This Past Weeks Tornado Outbreak at a Glance

A developing intense low pressure system resulted in an unstable air mass over parts of the Southern United States on October 24. The most intense tornado hit Rice, Texas where a high school was heavily damaged(see a youtube video by clicking the title of this tornado by Jason Mclaughlin) and several people were reported to be injured. That tornado was rated as an EF2. Another notable tornado, an EF1, hit Mobile, Alabama early on October 25.

There were a total of 74 confirmed tornadoes so far. 38 EF0s, 28 EF1s, and 8 EF2s
Of the 74 12 have been confirmed in Alabama.

As the low explosively deepened to become the most intense extra tropical low of non-tropical origins ever recorded in the continental United States, reaching as low as 953 mb (this is a record) over northern Minnesota this was basically like an inland medium-sized Category 3 hurricane, (just like the movie Day After Tomorrow) storms developed on the associated cold front late on October 25. A high risk of severe storms, the FIRST to be issued in OCTOBER since October 24, 2001 and the first in any fall month since November 15, 2005, was issued for parts of the Midwest including most of Indiana early on October 26, with both a tornado outbreak ahead of the front and a major derecho event as well was expected from the Gulf Coast to the upper Great Lakes. That morning, a few tornadoes struck, primarily around Lake Michigan, including a confirmed EF2 tornado four miles east of Peotone, Illinois, and another EF2 in Cridersville, Ohio, with more tornadoes reported near the Ohio River. Later that day, a confirmed EF1 tornado struck Middlesboro, Kentucky.In addition, widespread intense wind damage was also reported from Mississippi northward to Michigan.
The cold front tracked eastward on October 27 as the storm weakened. Additional tornadoes developed across the Mid-Atlantic states as the atmosphere remained unstable.In the end, it was one of the largest October tornado outbreaks ever recorded, even though none of the tornadoes were stronger than EF2.
We had a total of 18 confirmed tornadoes in Alabama for all of 2010 until the Oct 25th-27th outbreak when we dded 10 more to that. We are not even in our secondary tornado season yet so many more tornadoes may come before the end of the year. This is Alabama and we have been known for our warm and stormy Winters so stay weather aware.

What a Day!!

This is the scud that someone reported as a tornado on the ground. Notice the Hail shaft to the left of the scud.

You can see the funnel (nice wedge shape) behind the trees. I moved further north and thats when I was over took by rain.

Wall cloud in Limestone County

Another funnel with a nice lightning shot from screen capture.

Nice Supercell in Morgan county

While there where tons of Tornado warnings across the valley tonight. Some where verified others were not as of yet. The most significant damage seems to be in Dekalb County near the town of Geraldine. Severe Studios Associate Chaser Brett Adair was in the area reporting significant damage there. Here closer to home I captured a wall cloud, hail shaft and a tornado in Limestone County. The Tornado was in an open field and lifted as soon as it crossed behind me. In the small video clip you can see some small debris(and at the 1:15 mark you here some hit the windshield)blowing across the rod then I get overtook by rain as it approached. Not much in the way off good video since it was to my left and behind me and rain wrapped as well. All in all a very messed up day tons of rain with each cell made it hard to chase anything. video

More reports still to come.

Tomorrows Outlook!!!

Well if this morning was not enough another round of storms will affect us on Tuesday.During the day tomorrow, with a strong southerly flow bringing moisture back in here, and if the sun comes out as it is now, the air will become unstable, with CAPE reaching above 2,000 J/kg by tomorrow afternoon. the NAM is painting highs near 87F which could be a little high but do not be surprised to see highs near 83-85F.
The strongest dynamics will be across the Tennessee Valley of Alabama, Tennessee, and farther north, closer to the low, where the SPC has now painted a Moderate Risk. A Slight Risk is in place for nearly all of Alabama. The biggest threat for tornadoes looks to be north of the State, but expect the unexpected. Stay tuned for further updates and chase information.

Cullman Damage

When I first arrived in Cullman it seemed more as a downburst had happened since all the damage was in a small confined area, but after walking the town and surveying the damage I am to the conclusion that it was a small EF0-EF1 tornado touched down and then lifted almost immediately. The storm pushed in from the west along a squall line and the individual cell moved NE along the line damage could be found on all sides of buildings (N,S,E,AND W) The NWS survey team will be there later today and we will know for sure. Stay weather aware as tomorrow could be rough again as tis system will move in during the heating parts of the day. We are under a slight risk right now for all day Tuesday.

Few Storms To Our West

Well the severe chances for our area are starting to unfold. It is 4:30pm and it is still 83º and the instability values are climbing. Please be aware this is going to be a late night event when most everyone will be asleep. There is a chance that no tornado warnings will be issued and this will be just a heavy rain event, but be prepared just in case. The NWS has issued Severe Thunder Storm Watch # 708 for portions of Mississippi until 0300 UTC (10pm CDT) which may be extended to the east and include North and Central Alabama. Stay tuned for updates.

Severe Chances going Up!!!

Well as the small tornado outbreak has unfolded in North Texas we are watching the possible development of strong to severe storms here across Alabama. all models are looking more and more like we will see significant storms late Sunday night into Monday morning. Will this be a tornado outbreak like we have seen today? It is uncertain right now just what to expect. Please make sure you have your weather radio where you can hear it in case of inclement weather as it will be after everyone has gone to bed. As you can see from the models below if they hold true it will be a long late night watching and waiting. Here is the latest from the NWS.
A SECOND PEAK IN TSTM DEVELOPMENT...AND POTENTIALLY GREATER SEVERE WEATHER THREAT...IS SUGGESTED BY THE MODELS FOR THE SECOND HALF OF THE FORECAST PERIOD AS STRONGER HEIGHT FALLS SPREAD INTO THE MID SOUTH. WARMING DEW POINTS AMIDST INCREASING LOW-LEVEL SRH CONTINUES TO BOOST CONCERNS FOR TORNADOES AND GUSTY WINDS OVERNIGHT SUNDAY/EARLY MONDAY.SUFFICIENT CAPE AND STRONG SHEAR ABOVE THE INVERSION TO SUPPORT
ROTATING CELLS. ALTHOUGH THE THREAT FOR SEVERE WEATHER LOOKS
MARGINAL...AND STILL BETTER TO OUR SOUTH AND WEST...IT IS STILL
POSSIBLE ACROSS NORTH ALABAMA AS WELL. THIS WILL BE MONITORED AS FUTURE FCST TRENDS CLOSELY TO TRY TO
PIN DOWN SEVERE WEATHER SPECIFICS AND CONVECTIVE MODE


Day 2 convective outlook

Significant Severe for 3am Monday

SRH 6am Monday

Significant Tornado Parameter 3am Monday

NOGAPS 6am Monday

Looking Ahead to Next Week

Some of the models look impressive for Monday as we look to have plenty of instability and moisture for a decent chance at some strong storms. I do not see an all out severe weather outbreak, but an outside chance at a severe thunderstorm or even a tornado warning cannot be ruled out. All the models below are valid at noon on Monday as you can see from Image one it shows a squall line from Nashville down towards Tuscaloosa. The HPC is painting nearly 4 inches of rain by Thursday so this looks as if the main threat from these storms will be heavy rain and flooding potential. With that said in Alabama expect the unexpected. As of now the main window for the heavier rain and storms looks to be 9am Monday thru 9pm Monday. Stay tuned fro more updates.

Severe Next Week??????

Well as Summer turns to Fall and an unsettled weather pattern moves in we turn our attention to severe weather. Now it looks as if we could see our first round across the Southeast beginning on late Sunday night and into Monday morning with the main window now between 9pm Sunday til 9am Monday. We could see some sunshine return late Tuesday and Wednesday before a much stronger system moves in late Wednesday into Thursday. With this time of year expect the unexpected and any and all modes of severe weather can occur. very cold air will follow the storm system as it exits the area on Friday with the potential for heavy frost or even our first freeze, notice the 540 line on the Saturday graphic all the way to near Cullman. We will see if pans out for both the severe weather possibilities and the potential for a freeze. Stay tuned for any severe weather updates as the system draws near.
