AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
531 AM CDT THU AUG 21 2014

.DISCUSSION...
HIGH PRESSURE CONTINUES TO DOMINATE THE SOUTH BRINGING A TASTE OF
SUMMER. THE RIDGE OF HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE
REGION DURING THE NEXT FEW DAYS AND TEMPS WILL INCREASE INTO THE
MID/UPPER 90S WITH INCREASED DEWPOINTS AS WELL. HEAT INDICES WILL
BE BETWEEN 100-105 DEGREES. DEWPOINTS MAY MIX OUT THIS AFTERNOON
SLIGHTLY LOWERING THE EXPECTED HEAT INDEX VALUES TO JUST SHY OF
105...WILL HOLD OFF OF THE HEAT ADVISORY AT THIS TIME.

THE FORECAST WILL BE DRY UNTIL SUNDAY THROUGH WEDNESDAY WHEN A
SERIES OF DISTURBANCES WILL COME AROUND THE RIDGE. THE ECMWF AND NAM
WERE MORE OF A DRIER SOLUTION THAN THE GFS FOR THIS TIME FRAME...AND
DECIDED TO GO WITH THE DRIER OUTCOME AS THE GFS DOES NOT RETROGRADE
THE RIDGE LIKE THE OTHERS DO. TEMPS WILL BEGIN TO SLOWLY BACK DOWN
STARTING MONDAY WHEN STORMS MOVE INTO THE AREA AND EVEN FURTHER WHEN
THE RIDGE BEGINS TO BREAK DOWN. TEMPS WILL BE BACK TO NORMAL BY THE
MIDDLE OF THE NEXT WORK WEEK...LOWER 90S.
