Major severe outbreak likely

The Storm Prediction Center, as mentioned, has outlooked much of the southeastern quarter of the US for a moderate risk for severe weather. From now through tomorrow night, if you live as far west as E Texas, as far east as SE North Carolina, as far north as S Illinois, or as far south as Louisiana, South MS, South AL, or the Georgia-Florida border. How about that, Rick and Dewdrop.

Birmingham sounding shows CAPE progged at 3430 later.


From Jackson, MS NWS:

…SIGNIFICANT SEVERE WEATHER EPISODE POSSIBLE FROM THIS AFTERNOON
INTO SUNDAY MORNING…ESPECIALLY ALONG AND NORTH OF INTERSTATE 20…

AN OUTBREAK OF SEVERE THUNDERSTORMS CAN BE EXPECTED OVER THE AREA
FROM THIS AFTERNOON INTO EARLY SUNDAY. THE GREATEST RISK OF
WIDESPREAD…SIGNIFICANT SEVERE WEATHER WILL BE NORTH OF INTERSTATE
20.

SCATTERED SEVERE THUNDERSTORMS WILL BE POSSIBLE SATURDAY AFTERNOON
AND EVENING…MAINLY ALONG AND NORTH OF INTERSTATE 20. VERY LARGE
HAIL TO THE SIZE OF BASEBALLS…DAMAGING WIND GUSTS GREATER THAN 70
MPH…AND A FEW TORNADOES…COULD OCCUR WITH THE MOST INTENSE STORMS
DURING THIS TIME PERIOD. VERY UNSTABLE AIR AND INCREASING WIND
SHEAR…COMBINED WITH A STALLED FRONTAL BOUNDARY…WILL SUPPORT THE
SEVERE THUNDERSTORMS. THE RISK FOR TORNADOES WILL INCREASE WITH
STORMS THAT RIDE ALONG OR JUST NORTH OF THE BOUNDARY AND IF TORNADOES
DEVELOP THEY COULD BECOME STRONG.

LATER SATURDAY NIGHT…THE RISK FOR SEVERE WEATHER WILL INCREASE
ACROSS THE ENTIRE OUTLOOK AREA AS A THUNDERSTORM COMPLEX IS EXPECTED
TO DEVELOP OVER THE OZARK REGION AND MOVE RAPIDLY EAST DURING THE
OVERNIGHT HOURS. THERE MAY BE AN ENHANCED RISK FOR WIDESPREAD
DAMAGING WINDS…ESPECIALLY NORTH OF INTERSTATE 20. THE THUNDERSTORM
COMPLEX SHOULD REACH THE ARKLAMISS DELTA REGION BY AROUND
MIDNIGHT…AND EXIT EASTERN PORTIONS OF MISSISSIPPI BY AROUND
SUNRISE. IN ADDITION TO THE DAMAGING WINDS…LARGE HAIL AND A FEW
TORNADOES WILL ALSO BE POSSIBLE.

PEOPLE ACROSS THE AREA…ESPECIALLY THOSE PLANNING OUTDOOR
ACTIVITIES…SHOULD PAY CLOSE ATTENTION TO THE WEATHER THIS WEEKEND.



More to come!
