AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
910 PM CDT TUE APR 3 2007

.DISCUSSION...INTERESTING EVENING SO FAR...WITH THINGS LIKELY
GETTING MORE ACTIVE OVER THE NEXT HR OR TWO WITH DECENT STORMS GOING
ON BETWEEN 1-3AM.

TO START...AN UNSTABLE AIRMASS HAS BEEN IN PLACE MOST OF THE DAY
WITH LITTLE TO NO CAP. THE GREATEST INSTABILITY WAS TO OUR W/NW WITH
A WEAK CAP IN PLACE. A FEW STORMS FIRED...BUT THE DEEP LAYER ASCENT
WAS JUST NOT GOOD ENOUGH. ONE STORM DID GET OUT OF HAND OVER
WALTHALL AND MARION COUNTIES WHICH WERE ASSISTED BY SOME MERGING
OUTFLOW BOUNDARIES. NOW THAT THE SUN HAS SET...WE HAVE LOST SOME
HEATING. HOWEVER...TEMPS WILL REMAIN QUITE WARM IN ADVANCE OF THE
SFC FRONT SUPPORTING 1000-2000 J/KG OF MLCAPE. THESE GOOD
INSTABILITY WILL MAINLY BE LOCATED ACROSS THE NW HALF OF THE CWA
THROUGH THE EARLY MORNING HRS. BETTER ASCENT FROM THE MAIN S/W WILL
MOVE OUR WAY OVER THE NEXT 2-5 HRS ALONG WITH SOME JET LEVEL LIFT AS
THE NOSE OF A 90KT H25 JET MOVE INTO THE REGION. THE BEST AREA WHERE
LIFT...INSTABILITY AND FRONTAL CONVERGENCE COMBINE WILL BE ALONG AND
N OF A LINE FROM VICKSBURG TO CARTHAGE TO COLUMBUS. IM THINKING THE
FAR NW CWA WILL SEE ACTION BETWEEN 10PM AND 2AM...WITH A RIBBON
ACROSS THE N-CENTRAL CWA IMPACTED BETWEEN 1-4AM. ACTUALLY...AS I
WRITE...SAT IMAGERY IS INDICATING LIFT IS INCREASING FROM OUR DELTA
AREA ALL ACROSS N MS. THIS WILL LIKELY FILL IN WITH STORMS BETWEEN
10PM AND MIDNIGHT. BY 2-4 AM...LARGE SCALE ASCENT WILL WEAKEN AS
WELL AS INSTABILITY BECOMING MUCH LESS. THIS SHOULD SUPPORT AN
OVERALL WEAKENING OF THE LINE OF STORMS. VIEW OUR GRAPHICAST ON THE
WEB FOR A GRAPHIC.

AS FOR WHAT TO EXPECT...STEEP LAPSE RATES AND GOOD INSTABILITY HAVE
AND WILL CONTINUE TO SUPPORT LARGE HAIL. EXPECT THE NW CWA TO SEE
THE LARGEST HAIL...LIKELY QUARTERS TO SOME GOLFBALLS. DAMAGING WINDS
WILL ALSO BE A CONCERN. WITH THINGS ON THE DOWN SWING AFTER
THAT...HAIL WILL STILL BE POSSIBLE...BUT OF THE SMALLER VARIETY.

AS FOR ANY WATCHES...IM EXPECTING SOME OF OUR N/NW COUNTIES TO GO
UNDER A WATCH POSSIBLY WITHIN THE NEXT HR.

AS FOR THE GOING FORECAST/GRIDS...I HAVE UPDATED THE WX GRIDS TO
SHOW THE SLOWER PROGRESSION ACROSS THE CWA. I HAVE ALSO WARMED
HOURLY TEMPS TO MATCH CURRENT TRENDS WITH MUCH WARMER VALUES AHEAD
OF THE BOUNDARY.
