A RATHER AMPLIFIED MID/UPPER LEVEL PATTERN WAS IN PLACE OVER THE
GREATER NORTH AMERICAN DOMAIN. AN UPPER TROUGHING SETUP WAS IN
PLACE ALONG THE WEST AND EAST COAST, WHILE UPPER RIDGING WAS IN
PLACE OVER THE CENTRAL AND SOUTHERN GREAT PLAINS. UPPER LEVEL
DISTURBANCES MOVING SOUTHWARD ACROSS THE TENNESSEE VALLEY, ALONG
WITH EARLIER STRONG DAYTIME HEATING, RESULTED IN ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS. WHILE MOST PLACES WERE NOT
IMPACTED, LOCATIONS THAT RECEIVED RAINFALL HAD FROM A TRACE TO 1/4
OF AN INCH. AS OF THIS WRITING, ISOLATED CONVECTION WAS
CONTINUING FROM NW TENNESSEE TO NW OF ALABAMA. AREA TEMPERATURES
(AFTER HIGHS IN THE UPPER 80S/LOWER 90S) HAVE COOLED INTO THE 70S
WITH LIGHT WINDS.
REMAINING CONVECTION SHOULD CONTINUE TO SLOWLY FADE, AND SHOULD BE
OVER WITH AFTER MIDNIGHT. RESIDUAL MOISTURE, ESPECIALLY IN THOSE
AREAS THAT RECENTLY RECEIVED MEASURABLE RAINFALL, AND THOSE MORE
FAVORED SPOTS COULD BE IMPACTED BY FOG LATE TONIGHT. FOG SHOULD
REMAIN PATCHY TO AREAL IN COVERAGE, AND COULD BECOME DENSE
LOCALLY. LOW TEMPERATURES OTHERWISE SHOULD COOL INTO THE LOW/MID
60S WITH LIGHT WINDS.
DESPITE A MEAN NW UPPER FLOW AND SURFACE HIGH PRESSURE OVER THE
MID ATLANTIC, ANOTHER VERY WARM AND MOSTLY SUNNY DAY IS EXPECTED
TO END THE WORK WEEK. HIGH TEMPERATURES ON FRIDAY SHOULD RISE INTO
THE MID 80S TO AROUND 90.
SHORT TERM
(FRIDAY NIGHT THROUGH SUNDAY)
ISSUED AT 946 PM CDT THU SEP 11 2025
DRY CONDITIONS, WITH VERY WARM TO HOT CONDITIONS ARE EXPECTED FOR
THE UPCOMING WEEKEND. FRI/SAT NIGHT SHOULD FEATURE SEASONABLY COOL
CONDITIONS WITH LOWS IN THE UPPER 50S TO LOWER 60S. PATCHY LATE
NIGHT FOG CANNOT BE RULED OUT EITHER NIGHT, GIVEN LIGHT WINDS,
MOSTLY CLEAR SKIES AND LONGER LATE SUMMER NIGHTS (THAT ALLOW MORE
RADIATIVE COOLING). HIGHS SAT/SUN SHOULD RANGE FROM THE MID/UPPER
80S HIGHER ELEVATIONS, TO LOW/MID 90S THE WARMEST SPOTS.
LONG TERM
(SUNDAY NIGHT THROUGH THURSDAY)
ISSUED AT 946 PM CDT THU SEP 11 2025
A MEAN TROUGHING PATTERN ALONG THE EASTERN SEABOARD SHOULD
CONTINUE WAS WE GO INTO THE NEW WEEK. OUR LOCATION WELL TO THE
SE OF A FRONTAL BOUNDARY OVER THE GREAT PLAINS WILL HELP KEEP A
DRY AND WARM TREND GOING THROUGH THE MIDDLE OF NEXT WEEK. UPPER
RIDGING POSITIONED JUST WEST OF THE COASTAL TROUGH SHOULD ALSO
MAINTAIN ITS LOCATION. THUS DAILY HIGHS FOR THE MON-THU TIME
FRAME SHOULD RANGE FROM THE MID/UPPER 80S IN THE HIGHER ELEVATIONS
AND MORE EASTERN LOCATIONS, WITH LOW/MID 90S EXPECTED FOR THE
LOWER ELEVATIONS, ESPECIALLY WEST OF I-65. LOW TEMPERATURES EACH
NIGHT SHOULD AVERAGE IN THE LOW/MID 60S.

A WEAK UPPER LEVEL SYSTEM MOVING SOUTHWARD ACROSS THE AREA, ALONG
WITH STRONG DAYTIME HEATING HAS RESULTED IN ISOLATED TO SCATTERED
SHOWER AND THUNDERSTORM IN THE LATE AFTERNOON. THIS ACTIVITY
SHOULD SUBSIDE OVER THE NEXT FEW HOURS, THANKS TO A LOSS OF
INSTABILITY FROM DAYTIME HEATING. SURFACE HIGH PRESSURE OVER THE
EASTERN STATES WILL OTHERWISE CONTROL THE GENERAL WEATHER
SITUATION, WITH VFR CONDITIONS AND LIGHT WINDS. THERE IS A LOWER
END RISK OF PATCHY FOG FORMING BEFORE DAYBREAK FRI. ANY FOG THAT
FORMS SHOULD DISSIPATE SHORTLY AFTER SUNRISE, WITH VFR WEATHER
EXPECTED THEREAFTER. WINDS SHOULD BE FROM THE NE AT 4-8KT.
