AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
320 PM CDT SAT JUN 21 2003
MAIN FOCUS IS WITH THE BAND OF THUNDERSTORMS ACROSS SOUTHERN MS AND
HOW FAR NORTH THEY WILL GET THIS EVENING. AFTER TONIGHT...TEMPS WILL
BECOME OUR MAIN FOCUS.
THE AREA OF THUNDERSTORMS TO MY SOUTH HAS BEEN HOLDING IS OWN AND
DEVELOPING NORTHWARD OVER THE PAST 3 HRS. THIS COMPLEX OF STORMS
DEVELOPED ALONG THE STATIONARY FRONT AS A SHORTWAVE (S/W) TROUGH
MOVED EAST OUT OF SE TX. I AM CURRENTLY GOING TO MENTION 50
POPS...BUT MIGHT HAVE TO INCREASE THAT TO 60 BY ISSUANCE TIME. THE
LARGE MAJORITY OF THIS IS DIURNAL IN NATURE AND IS EXPECTED TO
DIMINISH BY MIDNIGHT AS THE S/W CONTINUES TO MOVE EAST.
FOR SUNDAY THE SFC FRONT WILL NUDGE A BIT MORE TO THE NORTH. THIS
WILL INCREASE LOW-LEVEL MOISTURE ACROSS AT LEAST HALF OF THE
FA...BUT WITH THE LACK OF ANY S/W AND AN UPPER RIDGE MOVING IN...I
AM EXPECTING ONLY ISOLATED ACTIVITY AT BEST ACROSS THE SOUTHERN
PORTION OF THE AREA.
FOR MON-THU...UPPER RIDGE WILL MOVE OVER THE REGION AND WE SHOULD
EXPECT TEMPS TO RISE INTO THE LOWER 90S. THERE WILL EXIST DECENT LOW
LEVEL MOISTURE...BUT THE EFFECTS OF SUBSIDENCE AND A MID LEVEL WARM
LAYER SHOULD HOLD MOST STORM ACTIVITY AT BAY. THE BEST CHANCES FOR
PRECIP WILL OCCUR ALONG AND WEST OF THE MS RIVER. THIS AREA WILL BE
JUST ALONG OR TO THE WEST OF THE UPPER RIDGE AXIS. THIS LOCATION
SHOULD SUPPORT BETTER RAIN CHANCES AS THE MID LEVEL WARM LAYER WILL
BE WEAKER.
A FAIRLY DECENT TROUGH WILL BEGIN TO EFFECT THE AREA BY FRIDAY...AS
THE UPPER RIDGE RETREATS TO THE SW. HIGH LOW LEVEL MOISTURE WILL BE
IN PLACE AND WITH THE UPPER FORCING MOVING IN...EXPECT MORE STORMS
ACROSS THE AREA. WILL MENTION NEAR CLIMO OR JUST ABOVE CLIMO POPS
FOR FRI/SAT.
