Some video from my chase trip to Arkansas on May 1, 2010. The area was under a "high" risk that afternoon and damaging tornadoes were expected however things did not quite pan out, though some storms produced damage. The incredible flooding in Memphis and Nashville, TN were the focus of this storm system.

PROBABILITY TABLE:
PROB OF 2 OR MORE TORNADOES                        :  80%
PROB OF 1 OR MORE STRONG /F2-F5/ TORNADOES         :  60%
PROB OF 10 OR MORE SEVERE WIND EVENTS              :  70%
PROB OF 1 OR MORE WIND EVENTS >= 65 KNOTS          :  60%
PROB OF 10 OR MORE SEVERE HAIL EVENTS              :  70%
PROB OF 1 OR MORE HAIL EVENTS >= 2 INCHES          :  50%

PROB OF 6 OR MORE COMBINED SEVERE HAIL/WIND EVENTS : >95%

  ...THIS IS A PARTICULARLY DANGEROUS SITUATION...
DESTRUCTIVE TORNADOES...LARGE HAIL TO 2 INCHES IN DIAMETER...
THUNDERSTORM WIND GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE
POSSIBLE IN THESE AREAS.
THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 70 STATUTE
MILES EAST AND WEST OF A LINE FROM 20 MILES NORTH NORTHWEST OF
NASHVILLE TENNESSEE TO 30 MILES SOUTH SOUTHWEST OF SELMA ALABAMA.
FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU3).
REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS.

Today might unfold to be a record day with large hail and the threat of long tracked dangerous tornadoes. I am in North Carolina at my brothers wedding and will unfortunatly miss out on this event but I wanted to posted some information regaurding the weather today. This is a real dangerous situation and life threatening to say the least so everyone needs to have a source of warning information for today and tonight across the whole Southeast.

The ABC 33/40 Weather Blog started as “WeatherTalk”, a daily op-ed piece on the ABC 33/40 web site which we started writing way back in 1996, when the station first signed on the air. Back then there were not that many Internet users, and nobody knew what a blog was anyway!

Drove to Troy in South Alabama to watch the snow roll in. Here is a short recap clip.

Here is the recorded Storm Alert Extreme Sessions that was held at the BJCC this past weekend. Thanks to James Spann, Brian Peters, and Jim Stefkovich of the National Weather Service for there great work presenting on Storm Spotting.

Rain should cover most of Alabama today with a more potent storm system due in here Friday. Here is ABC 33/40's morning weather video of the blog Alabama Wx .

Here is a map of what the HPC is predicting for rainfall valid Saturday morning through Saturday night. Obviously most of this will come down as scattered showers with heavy downpours. It should not rain all day in these spots but have the rain gear ready. The numbers in parenthesis are expected total points scored by both teams. The weather just might have an effect on that however. 

(Sorry for the small numbers but image software was not acting right this morning)

The Southeast United States is in for a rainy week ahead due to a upper and lower level low currently over Houston, TX. The system will be slow to move but will bring tons of moisture into the Southeast. Rainfall amounts could reach 5 inches over some parts of the south by the time the event is over. Severe weather is not likely with this system but there will be shear in the atmosphere due to the system and we cannot rule out spin up tornadoes throughout the event especially along the coast. Stay tuned into you your local weather team for updates as flooding could be an issue but have your umbrella ready and expect a soggy week.

Continuous Live Radar feed from Severe Alabama Wx. We will follow severe weather all across the country and feed it live to you. Hope this new feature helps during times of severe weather.

A frontal boundry will be drifting southward today allowing for some convective clusters along the gulf coast states. SBCAPE values will be significant enough for some strong storms with the main concern coming from wet microbursts and straight line winds. Mid level lapse rates are not that significant so hail should not be a main concern though some severe hail is possible. Stay tuned in to Severe Alabama Wx and your local media for updates throughout the day.
