AREAS AFFECTED...SRN HALF OF MS
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 071901Z - 072000Z
SCATTERED STORMS ARE EXPECTED TO DEVELOP OVER THE NEXT FEW HOURS
ACROSS THE SRN HALF OF MS. MICROBURSTS CAPABLE OF ISOLD POCKETS OF
WIND DAMAGE WILL BE PROBABLE THIS AFTERNOON.
VISIBLE SATELLITE/SURFACE COMPOSITE SHOWS AN AGITATED CU FIELD
BEGINNING TO BLOSSOM INTO PULSE STORMS AS TEMPS WARM THROUGH THE MID
90S THIS AFTERNOON. DUE TO STRONG HEATING...STEEP LOW LEVEL LAPSE
RATES NEARING DRY ADIABATIC HAVE DEVELOPED. THIS IS AHEAD OF A WWD
MOVING MCV LOCATED NEAR THE MS COAST. BOTH KLIX AND KMOB SHOW FLOW
IN THE 6-8 KM LAYER IN THE 25-35 KT RANGE WHICH WILL SUPPORT WWD
PROPAGATION/SOME CONTRIBUTION IN ORGANIZING COLD POOLS SUCH THAT
THERE MAY BE LOCALLY MAXIMIZED BACKGROUND DMGG WIND POTENTIAL OVER
THIS REGION. CURRENT THINKING IS A PULSE TSTM MODE WILL BE FAVORED
INITIALLY BEFORE SOME CONSOLIDATION OF COLD POOLS RESULTS IN A
CLUSTER OF STORMS. IN SUMMARY...A THREAT FOR SOME STRONG TO
LOWER-END SEVERE WIND GUSTS RESULTANT FROM WET MICROBURSTS--CAPABLE
OF SPORADIC POCKETS OF WIND DAMAGE-- WILL BE PROBABLE THIS
AFTERNOON. CONVECTIVE TRENDS WILL BE MONITORED FOR UPSCALE GROWTH
IN THE NEXT HOUR OR TWO IN CASE THE THREAT IS MORE WIDESPREAD THAN
CURRENTLY ANTICIPATED.
