AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
305 PM CDT FRI JUL 22 2005

.DISCUSSION...
AFTERNOON CONVECTION HAS PERSISTED OVER THE FAR SOUTHWEST COUNTIES IN THE FCST
AREA WHICH HAS KEPT TEMPS DOWN IN THE 70S. ELSEWHERE CLOUD COVER OVER NORTH LA
HAS KEPT TEMPS IN THE 80S OVER THE SOUTHEAST PARISHES. THE NORTHWEST SECTIONS OF
THE FCST AREA HAVE REACHED THE UPPER 90S TO LOW 100S. EXPECT THE CONVECTION TO
DISSIPATE LATER THIS EVENING WITH LOSS OF DAYTIME HEATING.

THE HEAT ADVISORY HAS VERIFIED FOR LOCATIONS ACROSS SE OK AND PARTS OF SW AR...BUT
NOT OVER NORTH LA. HEAT INDICES LOOK SIMILAR FOR SATURDAY WITH OUR NW COUNTIES
POSSIBLY MEETING CRITERIA...BUT WILL HOLD OFF AND LET THE NEXT SHIFT LOOK AT THE NEXT
MODEL RUN. WILL HIGHLIGHT THE HEAT INDICES IN THE ZONES.

THE UPPER RIDGE TO OUR NORTHWEST WILL TRANSLATE EAST TOWARD THGE TENNESSEE VALLEY
THROUGH THE WEEKEND AND EVENTUALLY TO THE SOUTHEAST STATES NEXT WEEK. A SERIES OF
IMPULSES WILL ROTATE AROUND THE UPPER HIGH WHICH WILL BRING A CHANCE FOR SCATTERED
AFTERNOON CONVECTION TO THE FCST AREA. AN UPPER TROF WILL AMPLIFY OVER THE MID
MS VALLEY BY TUESDAY BRINGING AN ATTENDANT SURFACE FRONT INTO THE FOUR STATE AREA.
THIS FRONT WILL BECOME STATIONARY AND BE THE FOCUS FOR DAILY CONVECTION FOR THE
LATTER PART OF NEXT WEEK. WILL GO WITH PERSISTENCE ON TEMPS AND LOW CHANCE POPS
EACH DAY.
