AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
252 PM CDT MON AUG 2 2010
.DISCUSSION...
HIGH PRESSURE WILL REMAIN IN CONTROL FOR THE NEXT SEVEN DAYS.
CONTINUED SUBSIDENCE FROM THIS SYSTEM...ESPECIALLY ACROSS THE
WESTERN HALF OF THE FORECAST AREA WILL ADD TO THE DRYING. LOWER
DEWPOINTS OVER THE NEXT COUPLE OF DAYS COULD KEEP HEAT INDEX
READINGS BELOW THE 105 THRESHOLD NEEDED FOR AN ADVISORY. IN THE
EAST...SLIGHTLY HIGHER MOISTURE LEVELS WILL KEEP DEWPOINTS ABOVE
70 FOR THE MOST PART. THIS COMBINED WITH TEMPERATURES OVER 100
DEGREES MAY KEEP THE NEED FOR AN EXCESSIVE HEAT WARNING GOING
BEYOND TUESDAY...WITH THE HEAT INDEX EXCEEDING 110 DURING THE
AFTERNOON. ONLY RELIEF FOR THIS AREA MAY OCCUR FROM ISOLATED
CONVECTION...ESPECIALLY AFTER WEDNESDAY, THIS DUE THE HIGHER
PWS...AND THE CENTER OF THE UPPER RIDGE SHIFTING A LITTLE MORE
TO THE WEST.
