Already today [ Sunday 9/30/12 ] there have been ‘isolated tornadoes’ in Mississippi with damage reported and the threat may continue to increase through this evening for areas in Southeast Louisiana, Southern and Central Mississippi and West Central / Southwest Alabama. Likely the threat of strong storms will continue through the overnight into Monday morning as well.
Looks like at this time the severe threat on Monday will be greatest in the Afternoon through late evening into the early overnight if anything comes from it. Possibility of strong storms Monday into Tuesday as well. At the least may see some damaging wind events with stronger thunderstorms. This is not a widespread threat. Isolated severe only. Not everyone will experience serve weather.
Wind shear will be adequate to support rotation with some of the stronger storms as they move from West to East through the area Monday through Monday night and possibly Tuesday morning. While the threat for Tornadoes is low, the threat is there. Heavy rain could also be a problem causing Flash Flooding for some due to abundant moisture being pulled north from the Gulf of Mexico over the same areas.
Here’s the current Storm outlook issued 2:00 PM EDT Sunday September 30 2012. This will likely shift north in updates issued later as the Low and adjacent fronts continue pushing East and North.
Probabilistic Damaging Wind Graphic
Probability of damaging thunderstorm winds or wind gusts of 50 knots or higher within 25 miles of a point.
Statement from Storm Prediction Center 2:00 PM EDT Sunday September 30 2012
FORECAST SOUNDINGS ACROSS THE WARM SECTOR IN ERN AL AND WRN GA MONDAY AFTERNOON SHOW MLCAPE VALUES OF 1000 TO 1500 J/KG WITH 0-6 KM SHEAR AROUND 45 KT. IN ADDITION…LCL HEIGHTS ARE FORECAST TO BE NEAR 500 METERS WITH 0-1 KM SHEAR OF 25 TO 30 KT. THIS ENVIRONMENT SHOULD SUPPORT ROTATING CELLS ELEMENTS EMBEDDED IN THE LINE OR DISCRETE SUPERCELLS AHEAD OF THE LINE ACROSS THE WARM SECTOR. AS THE ENVIRONMENT BECOMES MORE FAVORABLE DURING THE DAY…AN ISOLATED TORNADO THREAT IS EXPECTED TO DEVELOP MONDAY AFTERNOON. WIND DAMAGE COULD ALSO OCCUR WITH THE MORE INTENSE SEGMENTS OF THE LINE. GREATEST TORNADO POTENTIAL MAY OCCUR MONDAY AFTERNOON ACROSS NE AL AND NW GA INTO SE TN WHERE LOW-LEVEL WINDS ARE FORECAST TO BE BACKED TO THE SOUTHEAST WHICH WILL ENHANCE LOW-LEVEL SHEAR PROFILES.
