Area forecast discussion, Aug 5, 3:00 PM CDT, 1 hour 48 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
300 PM CDT FRI AUG 5 2005

.DISCUSSION...
COLD FRONT LOCATED ACROSS MISSOURI AND UPPER LEVEL LOW LOCATED ALONG
GULF COAST WILL BECOME THE FOCUS OF SHOWER AND THUNDERSTORM ACTIVITY
OVER THE NEXT FEW DAYS ACROSS THE MIDSOUTH. COLD FRONT WILL SAG
SOUTHWARD INTO THE MIDSOUTH BY SATURDAY...AND WILL EVENTUALLY WASH
OUT OVER THE AREA BY THE END OF THE WEEKEND. UPPER LEVEL LOW WILL
MOVE NORTHWARD ALONG THE MISSISSIPPI/ALABAMA BORDER AND BY
MONDAY/MONDAY NIGHT WILL BE LOCATED OVER PORTIONS OF THE MIDSOUTH.
UPPER LEVEL LOW WILL MOVE AWAY FROM THE MIDSOUTH BY MID WEEK UNTIL
THEN EXPECT CHANCES FOR RAIN TO BE SLIGHTLY HIGHER THAN THE NORMAL
DIURNAL CONVECTION. HOWEVER WILL STILL HAVE CHANCE POPS ACROSS THE
CWA WITH A RANGE FROM 30 TO 50 DURING THIS TIME PERIOD. LATER POPS
MAY NEED TO BE RAISED EVEN FURTHER...ESPECIALLY FOR MONDAY WHEN THE
LOW PASSES OVER PORTIONS OF THE MIDSOUTH. CONVECTION SHOULD ALSO
KEEP TEMPERATURES A TAD COOLER WITH HIGHS IN THE UPPER 80S TO LOWER
90S.

HIGH PRESSURE WILL RETURN TO THE CWA BY MIDWEEK AND WILL DOMINATE
THE WEATHER THROUGH THE END OF THE FORECAST PERIOD. EXPECT TYPICAL
SUMMERTIME DIURNAL CONVECTION AROUND THE MIDSOUTH. WILL PUT 30 POPS
DURING THE DAY WITH 20 AT NIGHT. HIGH TEMPERATURES WILL ALSO RETURN
TO THE MID 90S.
