00Z WATER VAPOR AND H4 RUC ANALYSIS SHOWS UPPER LEVEL RIDGING STILL
FIRMLY IN CONTROL OF THE SOUTHEASTERN PORTION OF THE CONUS. MAIN
NORTHERN STREAM FLOW AND ANY SIGNIFICANT IMPULSES REMAINS WELL TO
OUR NORTH TOWARD THE U.S CANADIAN BORDER. MAIN FEATURE EMBEDDED
WITHIN THIS FLOW IS A FAIRLY POTENT SHORTWAVE NOW EXITING THE
INTER-MOUNTAIN WEST AND OVER THE NORTHERN PLAINS/UPPER MS VALLEY.

KTLH 24/00Z SOUNDING PROFILE SHOWS A WELL MIXED LAYER UP TO AROUND
840MB. ABOVE THE BOUNDARY LAYER THE COLUMN REMAIN QUITE DRY WITH A
VERY DRY LAYER BETWEEN AROUND 600MB AND 400MB WHERE DEWPOINT
DEPRESSIONS APPROACH 50C.

AT THE SURFACE...HIGH PRESSURE CENTERED OFF THE SOUTHEAST COAST
CONTINUES TO RIDGE BACK WESTWARD OVER OUR REGION. HAD ANOTHER VERY
WARM DAY FOR LATE SEPTEMBER WITH HIGH TEMPERATURES REACHING THE
LOWER AND MIDDLE 90S. WITH THE SETTING OF THE SUN...TEMPERATURES ARE
NOW SETTLING BACK THROUGH THE 80S. THE AFTERNOON CU FIELD IS ALSO
BEGINNING TO DISSIPATE AND WILL LEAVE OUR REGION WITH MOSTLY CLEAR
SKIES FOR THE MAJORITY OF THE NIGHT.
