CONCERNING...TORNADO WATCH 179...
VALID 290425Z - 290630Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 179 CONTINUES.
SUMMARY...NEW THUNDERSTORM DEVELOPMENT OVER SOUTHEAST ARKANSAS WILL
POSE A SEVERE HAIL THREAT.
DISCUSSION...THUNDERSTORMS HAVE DEVELOPED OVER THE LAST 45 MIN OVER
SOUTHEAST AR, ALONG A PRE-FRONTAL BOUNDARY. THESE STORMS ARE IN A
VERY MOIST AND MODERATELY UNSTABLE AIR MASS WITH MLCAPE VALUE AROUND
1000 J/KG. STORMS HAVE INTENSIFIED RAPIDLY WITH MESH VALUES
SUGGESTING SEVERE HAIL IS ALREADY OCCURRING. VADS AT LZK/NQA AND
MODEL GUIDANCE SHOW SUBSTANTIAL VEERING OF LOW-LEVEL WINDS HAS
OCCURRED IN THIS AREA, SUGGESTING HAIL IS THE MAIN CONCERN AS THESE
STORMS TRACK EASTWARD INTO WW179 DURING THE NEXT COUPLE OF HOURS.
NEVERTHELESS, SUFFICIENT LOW-LEVEL SHEAR REMAINS FOR AT LEAST THE
RISK OF AN ISOLATED TORNADO.
