RT @DrGregForbes: Looks like a severe and possibly tornado outbreak on Christmas for se TX, s and central parts of LA, MS, AL, GA, FL panh.

Major severe weather outbreak possible Tuesday. 30% hatched on a three day outlook is rare.

FORECAST SOUNDINGS AT MIDDAY TUESDAY IN THE LOWER MS VALLEY DEVELOP
AN IMPRESSIVE SHEAR ENVIRONMENT AS THE MID-LEVEL JET APPROACHES THE
REGION FROM THE WEST. NAM FORECAST SOUNDINGS VALID TUESDAY AT 21Z
JUST SOUTHWEST OF JACKSON MS SHOW MLCAPE VALUES AROUND 1500 J/KG
WITH ABOUT 60 KT OF DEEP LAYER SHEAR. THIS COMBINED WITH 0-3 KM
STORM RELATIVE HELICITIES AROUND 400 M2/S2 COULD BE FAVORABLE FOR
SUPERCELLS AND TORNADOES. IF MANY CELLS CAN REMAIN DISCRETE…THEN
CONDITIONS COULD ALSO BE FAVORABLE FOR STRONG TORNADOES AS THE
LOW-LEVEL JET MOVES EWD ACROSS THE CNTRL GULF COAST STATES FROM
TUESDAY MORNING INTO THE AFTERNOON. AT THIS POINT…THE POTENTIAL
FOR WIDESPREAD WIND DAMAGE APPEARS JUST AS VIABLE. THE MAGNITUDE OF
THESE THREATS MAY DEPEND UPON THE DOMINANT STORM MODE. IF THE
FAVORED MODE ENDS UP BEING LINEAR…THEN WIND DAMAGE COULD BE THE
GREATER THREAT.

Severe weather/tornado outbreak likely on Christmas Day. If storms remain discrete, we may see a few strong tornadoes (EF2 ). Please pay attention to the forecast if you live anywhere in the Slight risk area, which stretches across southeastern Texas into most of Louisiana, southern Mississsippi and Alabama, and into extreme western Georgia and the panhandle of Florida. Some of the cities that will probably get the worst of this event include…



New Orleans, LA
Alexandria, LA
