NEAR TERM
(TODAY)
ISSUED AT 355 AM CDT THU SEP 10 2026
SFC HIGH PRESSURE SHOULD KEEP US MOSTLY DRY TODAY AS OUR AREA
REMAINS WEDGED BETWEEN TWO LOW PRESSURE SYSTEMS. AS THIS SFC HIGH
SHIFTS EASTWARD, SOUTHERLY FLOW WILL ENCOURAGE INCREASED
MOISTURE/DEW POINTS INTO THE TENNESSEE VALLEY AHEAD OF AN UPPER
LEVEL TROUGH. IN TURN, HEAT WILL CONTINUE TO BE A CONCERN TODAY AS
HIGHS CLIMB INTO THE LOW TO MID 90S WITH HEAT INDICES NEAR 100
DEGREES.
SHORT TERM
(THURSDAY NIGHT THROUGH SATURDAY NIGHT)
ISSUED AT 816 PM CDT WED SEP 9 2026
AS WE HEAD INTO THE END OF THE WORK WEEK, A SHORTWAVE TROUGH DIGS
DOWN ACROSS THE PLAINS AND TOWARDS THE TENNESSEE RIVER VALLEY.
THIS WILL PUSH A FRONT TOWARDS THE LOCAL FORECAST AREA THAT WILL
ULTIMATELY STALL JUST TO OUR NORTH. THIS FEATURE WILL PROVIDE AN
AREA OF FOCUS FOR SHOWERS AND THUNDERSTORMS TO DEVELOP BOTH FRIDAY
AND SATURDAY. THE GREATEST COVERAGE WILL BE DURING THE AFTERNOON
HOURS. WHILE NO SEVERE STORMS ARE FORECAST DUE TO THE LACK OF
SHEAR, CANNOT RULE OUT A STRONG STORM OR TWO CAPABLE OF PRODUCING
GUSTY WINDS GIVEN A DECENT AMOUNT OF INSTABILITY. OUTSIDE OF ANY
PRECIPITATION, IT WILL BE HOT AND HUMID WITH AFTERNOON HIGHS IN
THE LOWER 90S WITH OVERNIGHT LOWS IN THE UPPER 60S TO LOWER 70S.
LONG TERM
(SUNDAY THROUGH WEDNESDAY)
ISSUED AT 816 PM CDT WED SEP 9 2026
THROUGH THE LONG TERM FORECAST, HIGH PRESSURE LOOKS TO BUILD IN AGAIN
OVER THE MID ATLANTIC STATES AND EXTEND BACK INTO THE TN VALLEY. THIS
WILL INDUCE WEAK SSW FLOW AT THE SURFACE AND KEEP HUMID SUMMER LIKE
CONDITIONS IN PLACE EACH DAY. HIGHS LOOKS TO REMAIN IN THE 90S WITH
DEW POINTS IN THE HIGH 60S TO LOW 70S. THIS WILL PUSH HEAT INDICES
NEAR AND ABOVE TRIPLE DIGITS EACH DAY. WHILE NOT APPROACHING ANY
RECORDS, THESE TEMPERATURES AND DEW POINTS WILL BE UNSEASONABLY HIGH,
PRESENTING MORE LIKE SUMMER THAN MID SEPTEMBER. PLEASE MAKE SURE TO
CONTINUE TO PRACTICE PROPER HEAT AND SUN SAFETY DURING OUR
CONTINUED HOT AND HUMID CONDITIONS.
DUE TO THE HIGHER HUMIDITY FOR MID SEPTEMBER, WE WILL HAVE LOW
CHANCES FOR RAIN AND PERHAPS A STRAY THUNDERSTORM EACH AFTERNOON.
COVERAGE CURRENTLY LOOKS VERY SCATTERED. WITHOUT ANY SPECIFIC FORCING
MECHANISM IT WILL BE HARD TO NAIL DOWN SPECIFIC TIMES OR LOCATIONS
THAT MAY HAVE BETTER CHANCES FOR RAIN. PLEASE CHECK BACK FOR UPDATES
REGARDING OUR LOW RAIN CHANCES NEXT WEEK.
