Area forecast discussion, Jun 16, 5:03 PM CDT, 46 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
503 PM CDT THU JUN 16 2011

.DISCUSSION...THE MID LEVEL RIDGE WAS KEEPING MUCH OF THE CWA DRY
THIS AFTERNOON. WITH STORMS DEVELOPING IN A SEMI CIRCLE ON THE EDGE
OF THE CWA. THERE WAS A BOUNDARY DRAPED OVER THE AREA THIS MORNING...
THAT SEEMS TO HAVE SHIFTED TO THE NORTHEAST SLIGHTLY...WHERE MUCH OF
THE THUNDERSTORM ACTIVITY WAS DEVELOPING. GUIDANCE CAME IN WITH
CHANCE POPS ALONG THE HIGHWAY 82 CORRIDOR. SHOWERS AND THUNDERSTORMS
WERE BECOMING SCATTERED IN NATURE...SO WENT WITH HIGHER POPS FOR THE
LATE AFTERNOON AND EVENING. STORMS WERE GOING UP QUICKLY ACROSS THE
AREA. IN ADDITION TO THE DOWNBURSTS POTENTIAL...HEAVY RAIN WILL ALSO
BE A CONCERN. RADAR RAINFALL ESTIMATES WERE APPROACHING 4 INCHES IN A
FEW LOCATIONS. THINKING THERE WAS SOME HAIL CONTAMINATION OVER
NOXUBEE COUNTY WHERE ESTIMATES WERE FROM 5 TO 7 INCHES. SPC
MESOANALYSIS SHOWS CAPE VALUES FROM 2500-3000J OVER THE CWA.
SATELLITE SOUNDINGS SHOW PLENTY OF MID LEVEL LAPSE RATES AND
INSTABILITY. STORMS WERE DEVELOPING SOUTH OF THE BOUNDARY ALONG SOME
OUTFLOW...WITH NEW ACTIVITY IN CENTRAL MISSISSIPPI.

THE GFS CONTINUES TO SHOW RAIN LINGERING OVERNIGHT. EXPECTING MUCH OF
THE RAIN TO END BY MIDNIGHT. TOOK MUCH OF THE RAIN OUT BY TEN...BUT
LEFT SOME VALUES IN OVERNIGHT. THE RIDGE WILL CONTINUE TO BUILD IN
FROM THE WEST FRIDAY...BUT THE BOUNDARY MAY LINGER JUST TO THE EAST
OF THE AREA EARLY FRIDAY. LEFT SMALL RAIN CHANCES IN FOR THE EASTERN
HALF OF THE AREA FRIDAY AFTERNOON. BY FRIDAY NIGHT THE RIDGE WILL BE
IN PLACE. NOT EXPECTING MUCH ACTIVITY THROUGH THE WEEKEND. LOOKS LIKE
THE AREA WILL BE DRY FOR A FEW DAYS BEYOND FRIDAY. GUIDANCE VALUES
WERE GOOD FOR POPS AND TEMPS.

&&

.AVIATION...ISOLATED TSTMS CAN BE EXPECTED ACROSS THE AREA DURING
THE AFTERNOON INTO EARLY EVENING HOURS. ALTHOUGH STORMS CAN NOT BE
RULED OUT ACROSS OTHER AREAS...THE BEST CHANCE FOR STORMS WILL OCCUR
E OF A LINE FROM GLH-JAN-HBG. STRONGER STORMS WILL HAVE THE
POTENTIAL FOR DAMAGING WIND GUSTS. HAIL WILL ALSO BE POSSIBLE. TSTMS
WILL DIMINISH THIS EVENING AND END BY 10 PM. PATCHES OF LIGHT FOG
WILL BE POSSIBLE OVER SRN ZONES TOWARD MORNING...OTHERWISE VFR
CONDITIONS ARE EXPECTED DURING THE OVERNIGHT HOURS.
