Saying Goodbye to a Loyal Friend

Friday, February 29th, 2008

This morning, I had to part with the most incredible animal I have
ever owned.  While I am a dog lover (and said on television in
Huntsville once, while a dog was licking my face, “I love licking
dogs”, which immediately drew chuckles in the studio) and have been my
entire life, a very special life passed this morning at the Animal
Hospital of North Alabama.

Brad & Winston, Feb 2008

Winston was just shy of 10 years old, moved with me numerous times,
never bit or snapped anyone but the people in the vet’s office (who’d
blame him?), was the consummate watch dog, companion, running partner,
friend, listening ear, and cancer survivor (he lost his right front
leg to osteosarcoma in 2007).  But this morning, it seems a tumor in
his brain got the best of him, forcing a necessary decision to let him
leave with love, peace, and dignity.

Winston Feb 2008

I will miss him everyday, as will my family and all who ever met him.
While I have other animals, Winston, like most individual animals we
all own, was unlike any dog I have known.  

 Hugging My Pal, Feb 2008

On Leap Day, 2008, he made his ‘leap’, for the last time.

Friday’s Rains and Monday’s Storms Sandwich a Gorgeous Weekend

Thursday, February 28th, 2008

The coldest of the weather is now behind us for this go ’round, as they say in the rodeo, while rain showers are headed our way for Friday.  Though the showers will be brief, the rains will leave 1/4 to 1/2 inch rainfall totals on the ground.

But then, as Saturday morning dawns, we’ll see the clouds move away, the sunshine take over and allow temperatures to warm to near 60 degrees.  Then on Sunday, while most of us will see temperatures in the upper 60s, many of us will see high temperatures near or slightly above 70, with an increasing afternoon wind.

Weekend FOrecast

However, be prepared for a touch of Spring-like heavy to severe t-storms moving into the TN Valley Monday afternoon through early Tuesday.  Of course this all depends on the track of a large upper-level storm system that, as it swings on its Southern Route, will determine who sees rain, severe t-storms, and eventually potential snow.

Regardless, stay weather aware Monday afternoon through early Tuesday morning.

It’s Never Too Late For Snow…

Wednesday, February 27th, 2008

The above image is from the ABC 33/40 SKYCAM network in Stevenson, which is in Jackson County, and clearly shows the 1-2″ inches of snow that fell Tuesday night and Wednesday morning.  Bands of light snow flurries and snow flakes continue to fall throughout much of northeast AL and southern middle TN this afternoon as moisture is being wringed out of atmostphere within the northwesterly flow.  Expect some hazardous driving conditions in the higher elevations as some of the snowmelt will likely re-freeze on the mountainous roads after sunset tonight when temperatures return to below freezing.

A February Reminder… it is STILL February

Tuesday, February 26th, 2008

Behind the morning’s cold front, the temperatures have done exactly as predicted.  They started the say in the 50s and are ending the daylight hours in the 30s.  The lowest temperatures will fall into the mid- to upper- 20s in the Tennessee Valley Wednesday morning (and again on Thursday morning), but the biggest news is the likelihood of some scattered areas of snow showers and light snow flurries Tuesday evening and Wednesday in the early morning hours.

Overnight Light Snow 

There is a possibility that a lot of us see a light dusting on the grassy areas, and the highest elevations could top at 1-2″ of new snow.  Therefore, please be careful on mountain roads overnight and in the morning, since there will be some slick spots remaining.

A nice weekend will follow warmer weather on Thursday and a few showers late Friday, before the next threat for strong to severe t-storms head our way Monday night and early Tuesday morning, where there remains a slight chance for some light snow behind the rains.

Tornado Fatality Alley vs. Tornado Alley

Monday, February 25th, 2008

The December issue of Weather and Forecasting contains a spatial and temporal analysis of tornado Fatalities in the United States from 1880–2005 in order to assess region-specific vulnerabilities.  The analysis reveal that most tornado fatalities occur in the lower–Arkansas and Tennessee River Valleys, and lower–Mississippi River valleys of the southeastern United States—a region outside of traditional “tornado alley.” Analysis of variables including tornado frequency, land cover, mobile home density, population density, and nocturnal tornado probabilities demonstrates that the relative maximum of fatalities in the Deep South and minimum in the Great Plains may be due to the unique juxtaposition of both physical and social vulnerabilities.

 Tornado Fatality Alley

The spatial distribution of these killer tornadoes suggests that the above the national average mobile home density in the Southeast may be a key reason for the fatality maximum found in this area. A demographic analysis of fatalities during the latter part of the database record illustrates that the middle aged and elderly are at a much greater risk than are younger people during these events. For a copy of the paper contact Stephanie Kenitzer.  You can also see a release online at http://www.niu.edu/PubAffairs/RELEASES/2008/feb/tornado.shtml

Mark Twain Weather…. “If You Don’t Like the Weather…”

Friday, February 22nd, 2008

 The rains have ended, now, with appreciably less rainfall than I had hoped for, as we enter a weekend of cool temperatures and fairly nice weather.

Saturday… Cool, Breezy and some Sunshine.

Saturday Forecast

Sunday… Warmer, Clouds Increase, Perhaps a Sprinkle of Two

Sunday Forecast

Monday… Lots of Sunshine, a Spring-like Feel to the Day

Monday Forecast

The next increased chance for showers is Tuesday, when a very sharp cold front will move through the Tennessee Valley, bringing some light snow as close as middle Tennessee, and perhaps a few flakes to parts of North Alabama as the colder air sinks into place.

Rains THU and FRI, Strong Storms Monday

Tuesday, February 19th, 2008

Another very complex storm system that will keep forecasters on their toes is headed toward the Tennessee Valley on Thursday and Friday, while a very nice, but breezy, day will precede the rains on Wednesday.  With the rains coming our way, and with the drought situation not really improving as you might think after recent rains, let’s hope we see hours of rain on and off Thursday and Friday.  We might also have a few thunderstorms as well coming our way in the midst of the rain, but the heavier storms might arrive Monday Night and Tuesday Morning. 

Surface Chart for 2_25_08 

As the surface reflects a developing low pressure area over the Southeast, the upper level winds show an unstable air flow pattern developing overhead.

500mb Chart for 2_25_08

The start of the next workweek looks like it could get busy with strong to severe t-storms in the Southeast, and possibly Tennessee Valley.  This is another changing situation we will continue to follow here at WAAY-31.

Severe Weather Awareness Week

Monday, February 18th, 2008

Since this is severe weather awareness week, the National Weather Service has published lots of information on their website.  You can find it here.  Make sure you show this information to your family and others for whom you care and are concerned.

And if you have any questions that are not answered by what you find here, you can always email Storm Force 31 at weather@waaytv.com.

Gorgeous Saturday followed by Beautiful Rains Sunday

Friday, February 15th, 2008

As the Drought Monitor update this week shows more of North and Northeast Alabama still deep in the throes of an ‘Exceptional’ drought, remember that all rain is always beautiful right now, except when rains cause flooding concerns.  As you spend time outdoors on Saturday, with clouds and sun, don’t be surprised to see a few sprinkles from leftover rains that are falling in Texas Friday, as the clouds move overhead on Saturday.

Sunday Feb 17, 2008 Forecast

Sunday, the ‘Big Event’ for the weekend looks like it will have an earlier start than expected earlier in the week, with rains and a few thundershowers starting in Northwest Alabama in the morning, and moving through the Tennessee Valley into the late afternoon hours, with the majority of rain ending by sunset on Sunday.  That might set the stage for a few flurries EARLY in Monday morning, and perhaps for a few daylight hours in parts of North Alabama.  Then next week… it is time for milder weather and the next change for rain and t-storms coming in Thursday and Friday.

Check out the 7-Day Forecast for details.

Weekend Outook…A Mix of Wet & Dry

Thursday, February 14th, 2008

 

It appears that the weather pattern will remain relatively quiet until Sunday with only a slight chance of intermittent showers on Friday evening as a weak, moisture starved cold front passes the area.  The cold air behind the front is very limited, so a large drop in temperatures doesn’t seem plausible at this point.  Saturday will remain cool and dry with plently of sunshine overspeading the region, but the southerly winds will begin to transport large amounts of rich Gulf moisture that will increase cloud cover later in the day.  Fast-forward to Sunday….a developing storm system along the Texas Gulf Coast will move over parts of Louisiana and Mississippi dropping large amounts of rain before reaching North Alabama where the rainfall totals could add up quickly by Sunday evening.  As it looks at this point we could see rain gauges measuring nearly an inch of rain before the system exits late Sunday night and early Monday morning.  Large scale severe weather is not expected in North AL or Southern Middle TN, but a few renegade storms from the south could make their way into our area.  Most of the severe activity should stay along the Interstate 20 corridor where the energy and dynamics remain the greatest.  As the storm system begins to wrap up late Sunday evening we could see a changeover to light snow flurries as the temperatures begin to fall below freezing.  No large scale accumulation is expected, but we will keep an eye on it.  Check the 7-Day Forecast for details and changes.

NWS Storm Surveys

Tuesday, February 12th, 2008

After outbreaks of tornadoes or individual tornado occurances, the National Weather Service sends out teams of meteorologists to survey the storms, create detailed maps of storm or tornado strength, and includes pictures of storm damage.  The NWS Office in Huntsville continues to update the information regarding the 2008 Super Tuesday Tornado

Jackson County Path 

Lawrence County Tornado Path

One interesting piece of information is that the NWS NEXRAD Doppler Radar at Hytop, AL, apparently picked up a damage echo, meaning that as the storm was causing damage, bringing debris airborne, the radar picked up a spike in signal strength from the microwaves reflecting off of the large debris.  When I get those images I will post them on the blog.

It’s All About the SUN !

The Sun Also Sets

 

Climate Change: Not every scientist is part of Al Gore’s mythical “consensus.” Scientists worried about a new ice age seek funding to better observe something bigger than your SUV — the sun.


Related Topics: Global Warming


Back in 1991, before Al Gore first shouted that the Earth was in the balance, the Danish Meteorological Institute released a study using data that went back centuries that showed that global temperatures closely tracked solar cycles.To many, those data were convincing. Now, Canadian scientists are seeking additional funding for more and better “eyes” with which to observe our sun, which has a bigger impact on Earth’s climate than all the tailpipes and smokestacks on our planet combined.And they’re worried about global cooling, not warming.

Sun Spots and Solar Flares

Kenneth Tapping, a solar researcher and project director for Canada’s National Research Council, is among those looking at the sun for evidence of an increase in sunspot activity.

Solar activity fluctuates in an 11-year cycle. But so far in this cycle, the sun has been disturbingly quiet. The lack of increased activity could signal the beginning of what is known as a Maunder Minimum, an event which occurs every couple of centuries and can last as long as a century.

Such an event occurred in the 17th century. The observation of sunspots showed extraordinarily low levels of magnetism on the sun, with little or no 11-year cycle.

This solar hibernation corresponded with a period of bitter cold that began around 1650 and lasted, with intermittent spikes of warming, until 1715. Frigid winters and cold summers during that period led to massive crop failures, famine and death in Northern Europe.

Tapping reports no change in the sun’s magnetic field so far this cycle and warns that if the sun remains quiet for another year or two, it may indicate a repeat of that period of drastic cooling of the Earth, bringing massive snowfall and severe weather to the Northern Hemisphere.

Tapping oversees the operation of a 60-year-old radio telescope that he calls a “stethoscope for the sun.” But he and his colleagues need better equipment.

In Canada, where radio-telescopic monitoring of the sun has been conducted since the end of World War II, a new instrument, the next-generation solar flux monitor, could measure the sun’s emissions more rapidly and accurately.

As we have noted many times, perhaps the biggest impact on the Earth’s climate over time has been the sun.

Planck Institute Logo

For instance, researchers at the Max Planck Institute for Solar Research in Germany report the sun has been burning more brightly over the last 60 years, accounting for the 1 degree Celsius increase in Earth’s temperature over the last 100 years.

R. Timothy Patterson, professor of geology and director of the Ottawa-Carleton Geoscience Center of Canada’s Carleton University, says that “CO2 variations show little correlation with our planet’s climate on long, medium and even short time scales.”

Rather, he says, “I and the first-class scientists I work with are consistently finding excellent correlations between the regular fluctuations of the sun and earthly climate. This is not surprising. The sun and the stars are the ultimate source of energy on this planet.”

Patterson, sharing Tapping’s concern, says: “Solar scientists predict that, by 2020, the sun will be starting into its weakest Schwabe cycle of the past two centuries, likely leading to unusually cool conditions on Earth.”

“Solar activity has overpowered any effect that CO2 has had before, and it most likely will again,” Patterson says. “If we were to have even a medium-sized solar minimum, we could be looking at a lot more bad effects than ‘global warming’ would have had.”

In 2005, Russian astronomer Khabibullo Abdusamatov made some waves — and not a few enemies in the global warming “community” — by predicting that the sun would reach a peak of activity about three years from now, to be accompanied by “dramatic changes” in temperatures.

A Hoover Institution Study a few years back examined historical data and came to a similar conclusion.

“The effects of solar activity and volcanoes are impossible to miss. Temperatures fluctuated exactly as expected, and the pattern was so clear that, statistically, the odds of the correlation existing by chance were one in 100,” according to Hoover fellow Bruce Berkowitz.

The study says that “try as we might, we simply could not find any relationship between industrial activity, energy consumption and changes in global temperatures.”

The study concludes that if you shut down all the world’s power plants and factories, “there would not be much effect on temperatures.”

But if the sun shuts down, we’ve got a problem. It is the sun, not the Earth, that’s hanging in the balance.

Lawrence Co. Tornado Upgraded to EF-4

Friday, February 8th, 2008

Lawrence/Morgan County Tornado

February 6, 2008

Survey Summary

EF-Scale Rating EF-4
Est. Peak Wind 170 MPH
Est. Path Length 16.7 miles (14.0 in Lawrence, 2.7 in Morgan)
Maximum Path Width 1/2 mile

Representatives from the National Weather Service and the Lawrence County Emergency Management Agency conducted an storm survey of damage that occurred in Lawrence County and Morgan County, Alabama early in the morning of February 6, 2008.

The damage was determined to originate from a strong tornado, which at its peak had winds of approximately 170 MPH, giving it a rating of EF-4 on the Enhanced Fujita Scale. Based on reports and an aerial survey conducted by the Lawrence County EMA, the tornado is believed to have originally touched down near the Pinhook community in south-central Lawrence County (just north of the Bankhead National Forest) around 3:00 AM CST. The tornado remained on the ground for approximately 16.7 miles; the first 14 miles of the track occurred in Lawrence County, tracking through the Aldridge Grove, Fairfield, Five Points, Midway, and Caddo communities, and it continued into Morgan County for 2.7 miles, lifting near the Trinity community west of Decatur around 3:20 AM CST.

The most significant damage occurred in two main areas. The first occurred just south of the Pinhook community, near the intersection of County Road 92 and 188. The second occurred north of Aldridge Grove near the intersection of County Road 94 and 183, where three fatalities occurred. Numerous homes received significant structural damage, including a 2300 square foot/2-story brick house that was nearly leveled off its foundation. Large trees, with diameters up to 4 feet, were completely snapped, with many uprooted. Fence posts embedded in concrete were ripped out of the ground and vaulted 50 to 100 feet in several different directions. A truck was thrown over a distance of more than 100 yards into an open field.

Tornado watch #41 had been issued for all of north Alabama at 10 PM CST, and was in effect until 5 AM CST (it was later extended until 7 AM CST). A tornado warning for Lawrence County was issued at 2:40 AM CST, and a follow-up warning for northwestern Morgan and southeastern Limestone was issued at 3:08 AM.

Damage Surveys From Feb. 6th Storms

Thursday, February 7th, 2008

 

February 6, 2008 Tornadoes


Summary
A series of supercell thunderstorms swept across the Mid-South and Southeast states on February 5 and 6, 2008. The storms produced multiple tornadoes across Arkansas, Kentucky, Tennessee, Mississippi, and Alabama, causing at least 50 fatalities and many more injuries.Initial storm surveys have been completed on two significant tornadoes that occurred within the NWS Huntsville area of responsibility: one that occurred around 3 AM in Lawrence County (possibly including far western Morgan County), and one that occurred in eastern Jackson County.Several days in advance of the storms, local National Weather Service offices and media partners began to mention the potential for significant weather across the region. A tornado watch was in effect from around 10 PM on the evening of the 5th, through 5 AM Wednesday morning (the watch was later extended until 7 AM).Additional information regarding weather conditions, radar data, and storm surveys will be posted to this information as they become available.
