/ISSUED 1048 AM CDT TUE SEP 1 2015/
AREAS OF DENSE FOG MAINLY NEAR BODIES OF WATER AND IN THE VALLEYS
HAVE FINALLY DISSIPATED. CURRENT VIS SATELLITE SHOWS TERRAIN
INFLUENCED CU ALREADY DEVELOPING AND ADDITIONAL CLOUD COVER MOVING IN
FROM THE SW.

TAKING A LOOK AT REGIONAL WATER VAPOR...THERE ARE 3 UPPER LEVEL
FEATURES IN PLAY. THERE IS AN UPPER LEVEL LOW OVER TX AND LA THAT
WILL STREAM CLOUDS INTO THE REGION TODAY AND AN EMBEDDED LOW ACROSS
INDIANA. FINALLY...THERE IS A BROAD RIDGE OF HIGH PRESSURE ACROSS
THE SOUTHEAST COAST. HIGH PRESSURE WILL BUILD TODAY ALLOWING FOR A
DRY FORECAST AND TEMPS TO WARM UP INTO THE UPPER 80S/LOWER 90S.
ADJUSTED DEWPOINTS FOR CURRENT TRENDS AND UPSTREAM OBS. OTHERWISE THE
FORECAST WAS ON TRACK FOR TODAY.
