DISCUSSION
KEY MESSAGE 1: ABOVE SEASONAL TEMPERATURES AND DRY CONDITIONS
WILL PREVAIL THROUGHOUT THE WEEK. A COLD FRONT WILL BRING
COOLER TEMPERATURES THIS WEEKEND.
NOW THAT THE FRONT HAS MOVED THROUGH AND THE REMNANTS OF
ISAIAS ARE NOW OUT OF OUR HAIR, DRIER AND WARMER CONDITIONS WILL
MOVE INTO THE AREA. HIGH PRESSURE WILL BUILD OVER THE CENTRAL US
THROUGH THE EARLY HALF OF THE WEEK AND SLOWLY BUILD EASTWARD BY
THE END OF THE WEEK. THIS WILL LEAD TO DRY CONDITIONS THROUGH
THE WORK WEEK AND THE ONLY CONCERN WILL BE FOR NEAR RECORD HIGHS
GIVEN THE STRENGTH OF THE UPPER RIDGE. TEMPERATURES BY THE END
OF THE WEEK WILL BE IN THE UPPER 80S TO MAYBE EVEN 90 DEGREES
ACROSS SOME INTERIOR AREAS. THIS WILL CERTAINLY FLIRT WITH SOME
RECORD HIGHS AS WE GO THROUGH THE WEEK. BY THE WEEKEND, OUR NEXT
SYSTEM WILL SWING THROUGH AS THE UPPER TROUGH BREAKS DOWN AND A
COLD FRONT MOVES THROUGH THE AREA BRINGING SIGNIFICANTLY COOLER
CONDITIONS TO THE AREA.
AVIATION /00Z MONDAY THROUGH FRIDAY/
12/00Z TAFS:
KCHS/KJZI/KSAV: VFR THROUGH 13/00Z.
