CONCERNING...TORNADO WATCH 251...253...254...

VALID 030009Z - 030145Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH
251...253...254...CONTINUES.

TORNADO WATCH 251 CONTINUES UNTIL 01Z...A REPLACEMENT WATCH /OR
LOCAL WFO EXTENSION/ MAY BE NEEDED WITHIN THE HOUR. TORNADO WATCHES
253/254 CONTINUE UNTIL 05Z.

A NUMBER OF SEVERE STORMS/SUPERCELLS CONTINUE EARLY THIS EVENING
ESPECIALLY ACROSS TORNADO WATCHES 251/253. THE MOST PROLIFIC
SUPERCELLS WITH HISTORY OF TORNADOES CONTINUE ACROSS NORTHEAST MS AT
THIS TIME...WITH TWO DISTINCT SUPERCELLS NEAR THE NEW ALBANY AND
BOONEVILLE MS VICINITIES AS OF 2350Z. THE BOUNDARY LAYER WINDS
WITHIN THIS NEAR STORM CORRIDOR HAVE BACKED OVER THE PAST FEW HOURS
/REFERENCE TUPELO MS OBS/...ALTHOUGH DIMINISHING
INSTABILITY/INCREASING CINH WITH EAST EXTENT ACROSS NORTHWEST
AL/MIDDLE TN SUGGEST A WEAKENING TREND COULD OCCUR WITH THESE STORMS
OVER THE NEXT FEW HOURS.

OTHERWISE...THE NEAR STORM ENVIRONMENT REMAINS FAVORABLE FOR
SUPERCELLS/TORNADOES FROM NORTHERN AL INTO FAR EASTERN AR/NORTHERN
MS AND ADJACENT PORTIONS OF TN. A 30-50 KT LOW LEVEL JET IS
CONTRIBUTING TO 0-1 KM SRH OF 200-500 MS/S2...HIGHEST ACROSS
NORTHERN MS/NORTHWEST AL INTO TN.

IN SPITE OF PLENTIFUL STORMS IN THE PREFRONTAL WARM SECTOR...WITH
THE SYNOPTIC COLD FRONT ONLY GRADUALLY ADVANCING EASTWARD EARLY THIS
EVENING...PORTIONS OF TORNADO WATCH 251 MAY NEED TO BE REPLACED /OR
LOCALLY EXTENDED/ PRIOR TO 01Z. SHORT TERM MODEL GUIDANCE SUGGESTS
STORMS SHOULD INCREASE ALONG THE COLD FRONT THE REMAINDER OF THE
EVENING.
