NEAR TERM
(TODAY)
ISSUED AT 356 AM CST TUE NOV 4 2025
LIGHT WINDS AND CLEAR SKIES HAVE ALLOWED TEMPERATURES THIS MORNING
TO DIP DOWN INTO THE UPPER 30S TO LOWER 40S. WITH A FEW MORE HOURS
UNTIL SUNRISE, EXPECT AREA TEMPERATURES TO DROP A FEW MORE
DEGREES. UNLIKE YESTERDAY MORNING, FOG HAS REMAINED CONTAINED TO
ALONG THE RIVER BASED ON NIGHTTIME MICROPHYSICS SATELLITE
IMAGERY. GIVEN THAT NO SITES HAVE SHOWN MUCH VISIBILITY REDUCTIONS
AS OF YET, THE THREAT OF WIDESPREAD DENSE FOG APPEARS LOW.
WITH HIGH PRESSURE CENTERED OVERHEAD, AN OVERALL NICE FALL DAY IS
IN STORE. AMPLE SUNSHINE COMBINED WITH SOUTHERLY FLOW WILL HELP
TEMPERATURES CLIMB UP INTO THE UPPER 60S TO LOWER 70S THIS
AFTERNOON.
SHORT TERM
(TUESDAY NIGHT THROUGH THURSDAY)
ISSUED AT 922 PM CST MON NOV 3 2025
FOR THE REMAINDER OF THE WEEK, LOW TEMPERATURES WILL BECOME
MILDER. HIGH PRESSURE OVER THE REGION SHOULD SHIFT TO THE EAST
DURING WED/THU, RESULTING IN A DEEPER SOUTHERLY FLOW. THIS WILL
HELP MODERATE DAILY TEMPERATURES. LOWS TUE NIGHT SHOULD COOL INTO
THE LOWER 40S, AND LOW/MID 40S WED NIGHT. EVEN WITH MILDER
CONDITIONS, WE CANNOT TOTALLY RULE OUT LATE NIGHT PATCH FOG
DEVELOPMENT, CONFINED MAINLY IN/NEAR WIND SHELTERED LOCATIONS AND
NEAR BODIES OF WATER. AND UNDER GENERALLY SUNNY TO PARTLY CLOUDY
SKIES, HIGH TEMPERATURES ON WED/THU SHOULD RISE INTO THE LOWER 70S
BOTH DAYS.
LONG TERM
(THURSDAY NIGHT THROUGH MONDAY)
ISSUED AT 922 PM CST MON NOV 3 2025
TWO MAIN FEATURES OF FOCUS FOR THE LONG TERM PERIOD WILL BE A
SYSTEM THAT BRINGS POTENTIALLY STRONG STORMS FRIDAY AND AN INFLUX
OF COLD AIR EARLY NEXT WEEK. SIGNIFICANT DISAGREEMENT REMAINS IN
CLUSTERS REGARDING THE EVOLUTION AND TRACK OF AN UPPER LEVEL
DISTURBANCE SHIFTING GENERALLY EASTWARD THROUGHOUT THE U.S. INTO
THE TENNESSEE VALLEY VICINITY THIS WEEKEND. LREF SHOWS UP TO
400-500 J/KG OF CAPE MOVING IN ALONG AND WEST OF I-65 FRIDAY
AFTERNOON/EVENING, WHICH COULD ALLOW SOME STRONG STORMS IF
REALIZED. HOWEVER, CONFIDENCE REMAINS LOW DUE TO THE
AFOREMENTIONED DISAGREEMENT. BLENDED GUIDANCE WAS KEPT IN THE
FORECAST THROUGH THE LONG TERM DUE TO UNCERTAINTY, WHICH BRINGS
MEDIUM CHANCES OF SHOWERS AND THUNDERSTORMS INTO THE AREA BY
FRIDAY AFTERNOON AND CONTINUES RAIN CHANCES THROUGH FRIDAY
EVENING.
ENSEMBLES ARE AGREEING ON AN INFLUX OF COLD AIR EARLY NEXT WEEK,
IN WHICH WE COULD DROP INTO THE UPPER 20S TO LOW 30S FOR OVERNIGHT
LOWS (POTENTIALLY PROMPTING FREEZE PRODUCTS). THE CLIMATE
PREDICATION CENTER (CPC) HAS OUTLOOKED PORTIONS OF NE AL IN A
MODERATE RISK (40-60%) FOR MUCH BELOW NORMAL TEMPERATURES ON
NOVEMBER 11TH. THEREFORE, IF YOU HAVE ANY AGRICULTURAL OR OUTDOOR
INTERESTS, IT WILL BE IMPORTANT TO STAY UP TO DATE ON THE LATEST
FORECAST THROUGH THE WEEKEND.
AVIATION
(06Z TAFS)
ISSUED AT 1133 PM CST MON NOV 3 2025
CLEAR SKIES AND LIGHT WINDS PREVAILED ACROSS THE AREA. GIVEN
LONGER FALL NIGHTS, A RISK FOR MORE FOG IN THE OVERNIGHT REMAINS.
HAVE MVFR VSBY REDUCTIONS BEGINNING AT 07Z AT KMSL, AND 08Z AT
KHSV. VSBY REDUCTIONS COULD BECOME LOWER, HOWEVER NOT ENOUGH
CONFIDENCE TO MENTION THAT AT THIS TIME. ANY FOG THAT FORMS SHOULD
DISSIPATE SHORTLY AFTER SUNRISE TUE MORNING, WITH VFR WEATHER
RETURNING. LIGHT WINDS ARE EXPECTED FOR THE NEXT 24 HOURS.
CLIMATE
ISSUED AT 1246 AM CST TUE NOV 4 2025
