CONCERNING...SEVERE THUNDERSTORM WATCH 290...
VALID 090155Z - 090400Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 290
CONTINUES.
SUMMARY...AN EVOLVING THUNDERSTORM COMPLEX WILL MOVE SOUTHEASTWARD
WITH A RISK FOR SEVERE GUSTS THIS EVENING.
DISCUSSION...ONGOING CONVECTION OVER TORNADO WATCH 287 AND SEVERE
WATCH 290 HAS GROWN UPSCALE INTO AN ORGANIZED AND LINEAR CONVECTIVE
COMPLEX THIS EVENING. FURTHER UPSCALE GROWTH IS LIKELY AS THE
CLUSTER INTERACTS WITH A VERY UNSTABLE ENVIRONMENT (MLCAPE 4000+
J/KG) AND A 25-35 KT SOUTHERLY LOW-LEVEL JET. THE STRONG INSTABILITY
AND COLD POOL WILL LIKELY SUPPORT SEVERE GUSTS THROUGH THIS EVENING.
A FEW SIGNIFICANT GUSTS TO 75+ MPH ARE ALSO POSSIBLE.
OBSERVED LOW-LEVEL SHEAR IS ALSO FAIRLY STRONG FROM THE ICT VAD
(0-1KM SRH OF 100-200 M2/S2). THIS COULD SUPPORT A COUPLE OF
TORNADOES, BOTH WITH THE LINEAR CLUSTER, AND WITH INTERACTING CELLS
AHEAD OF THE OUTFLOW. WITH THE COMPLEX EXPECTED TO CONTINUE
EAST/SOUTHEAST, THE RISK FOR SEVERE WIND GUSTS REMAINS HIGH ACROSS
WW290.
