Quiet

The weather has been quiet lately in Alabama and so have I also been quiet on this blog. I think I speak for most weather geeks in Alabama when I say that the dry and warm weather that we have experienced in recent days has been most welcome. It seemed like we had some kind of severe weather threat every three days between mid February and mid April. I exaggerate slightly, but it has been an active spring and I am certainly enjoying a break.

Even though this spring has been active in Alabama, I can only think of one tornado rated higher than EF2, which was the Marshall-Dekalb EF3. Perhaps the best tornado photo ever made in Alabama was made of this one as it was actually a waterspout, crossing the Tennessee River at Lake Guntersville. Most of the events this spring have caused few, if any injuries. Sadly, there were two tornado related fatalities associated with the April 19 outbreak. There were 17 tornadoes in Alabama that day which were confirmed byNWS surveys. One of my best friends, who lives in Wren, south of Moulton, was in the path of the EF1 that went through Lawrence County.

Even as recently as April 23, there were some powerful storms that developed over extreme NE Alabama that produced large hail in Georgia. Andy Kula, meteorologist with the NWS Huntsville, took this picture of the top one of those storms from the roof of the Huntsville NWS Office, looking east.

Severe weather season is certainly not over and I anticipate that we will have more to talk about in the coming weeks. Yesterday was a "High Risk" day in parts Texas, Oklahoma, and Kansas. There were tornadoes out there each of the past two days and there were some really good videos made by chasers, but at first glance it doesn't appear that the high risk was warranted.

Stay tuned. In the mean time, I am getting away from the computer and riding to Atlanta tonight to take in the Braves/Cardinals games with two of my best friends since school days. I won't divulge how many years I have known them.

Closer Look at Lawrence County Tornadoes 4/19/09

My map showing approximate paths of April 19, 2009 Lawrence County, Alabama tornadoes.


Screen capture from WAAY 31 TV's coverage at 6:02 PM CDT on 4/19/09. This shows the approximate location of the first tornado (EF0). At approximately 6:12, meteorologist Gary Dobbs of WAAY called the station from his home in Mount Hope, reporting a wall cloud to his south. He also relayed scanner reports of power lines down on CR 22 and a tree on a car on CR 25.


Screen capture from WAAY 31 TV's coverage at 6:17 PM CDT on 4/19/09. This shows the approximate location of the second tornado (EF1).


Screen capture from WAAY 31 TV's coverage at 6:18 PM CDT on 4/19/09. This shows the approximate location of the second tornado (EF1) on the velocity display.


Screen capture from WAAY 31 TV's coverage at 6:23 PM CDT on 4/19/09. This shows the approximate location of the second tornado (EF1).


Screen capture from WAAY 31 TV's coverage at 6:24 PM CDT on 4/19/09. This shows the approximate location of the second tornado (EF1) on the velocity display near the end of it's path.

Around 6:33 WAAY reported that the Lawrence Countnd EMA reported large trees being down, power out, and a tree on a home near Wren. Later I relayed a report from my friend who lives on Highway 33 of numerous trees snapped and uprooted. He also mentioned a tree down on his mother's home and a neighbor's home.

A wet and stormy afternoon is beginning across North Alabama. Watches have been issued to the west. A severe thunderstorm watch is in effect for northern Mississippi and western Tennessee. Storms are lining up. A watch may soon be issued for westeren Alabama. I will be watching things closely on radar. There is a chance I will get out and do some storm spotting, but it is unlikely I will drive far from home.

A tornado warning is in effect for Washington County in southwestern Alabama.

Mini chase with the boys.....

Monday 4/13/09 was a weird weather day. A gravity wave/wake low moved through Alabama during the overnight hours on Sunday night/Monday morning, blowing down countless thousands of trees. In Central Alabama, Alabama Power indicated that 150,000 customers were without power. I hope to post more about that event soon. Then a "freak" tornado warning was issued during the after noon hours (see previous post), and finally another batch of storms moved through during the evening.

Before sunset, I took the boys on a "mini-chase" of one of those storms that was marginally severe and relatively close to home. I was hoping we would get to see a little hail, but it fell apart as it approached. My son David uploaded the following video. I may later post some radar captures he made showing how the storm literally fell apart as it approached.

Today's tornado warning......

We were under a tornado watch but conditions were not really very favorable for tornadoes. The boys and I were playing ball at the park close to home. Here is a time lapse of the storm responsible for the warning. I did see a wall cloud photo so the storm was dangerous in NW Madison and NE Limestone.

EF3 Tornado - Marshall, Jackson, Dekalb

An EF-3 Tornado was confirmed by the National Weather Service in Huntsville for Marshall, Jackson and Dekalb counties on Good Friday April 10, 2009, from 3:05 until 3:40 p.m. The tornado was on the ground for 28 miles and it was one-half mile wide at its widest point.

The National Weather Service Huntsville storm survey can be found here
.

I traveled though the Grant and Waterfront communities yesterday and took some pictures of the damage. I will post those later. It is amazing how the tornado traveled down the side of the mountain and really seemed to intensify when it approached the Lake Guntersville.

Following are three videos with the excellent real time coverage provided by WHNT Chief Meteorologist Dan Satterfield, Spencer Denton, and news staff. These videos concenttrate on this particular storm, before the warnings were issued, before the tornado touched down, while the tornado was on the ground, and eyewitness reports as it was ending, including an impressive viewer photo of the tornado. Dan did an excellent job on this storm (as did the NWS Huntsville) and anyone who wanted to be warned certainly had access to excellent weather coverage. Fortunately no deaths were reported.

Cullman County Storm Video

On April 10, 2009 around 3 p.m., a severe-warned storm moved across northern Cullman County. It did not actually develop into a rotating storm while it was in Cullman County but you can see the beginnings of a potential future wall cloud developing in this video. This storm did produce large hail north of Vinemont and became much stronger as it moved to the east of Cullman County.

Preliminary story on today's chase....



I did a lot of of storm chasing in Alabama today. I aw two wall clouds, hail, and severe thunderstorm. I was with John Brown who was streaming from Blount County.

Here is an intial summary in reverse chronological order.

pine tree uprooted on highway 160 in Hayden from the storm that came through at 4:55

Tree also blew down at the Hayden Post Office at 4:55 as the severe thunderstorm rolled through.
pea sized hail and high winds just blew through the hayden po also down spout from gutter blew off post office building #alwx at 455pm
John Brown and I are going to the Hwy 160 exit to follow the storm that is moving out of Walker County 4:45
3:45 John are at the guy hunt rest stop in good hope --- no sign of any wall cloud but a big ct g strike east of good hope...
John is streaming a possible wall cloud nw of cullman from 157/65

john brown and i are at 157 in cullman on 165 at 3 pm
Trees down on lines on hw 67, east of wheeler wildlife refuge, tree down at dairy queen in e decatur on 67

2:05 hail on hwy 24 e of moulton
at town creek on hwy 157 at 125pm 73, light rain, gusty south winds

large wall cloud---classic--- moving w and nw of leighton in the past few mins at 1:13
12:31 in Town Creek in Lawrence Co on AL HWY 20, at intersection of Hwy 101, south of TVA Wheeler Dam. 75, mostly cloudy.
Mostly Cloudy (dark skies) and 75F ne of Moulton at 12:16. #alwx
Made a quick stop at Whiits BBQ in Decatur....Now headed to Moulton.....77 on the car thermometer and mostly sunny at 11:50.

If you live in N AL your wx radio should have alerted you at 11:22 of a TORNADO WATCH until 7pm. Stay close to a source of wx info.

Moderate risk for severe wx expanded. http://tinyurl.com/bar6
