NEAR TERM
(REST OF TODAY AND TONIGHT)
ISSUED AT 1020 AM CST WED FEB 25 2026
A SLOW MOVING AND WEAKENING COLD FRONT EXTENDING FROM NORTH
CENTRAL OHIO WSW INTO NE OKLAHOMA CONTINUES TO EDGE SOUTHEAST
TOWARDS THE TENNESSEE VALLEY THIS MORNING. THIS FRONT SEEMS TO BE
LOSING STEAM AS IT TRIES TO PUSH INTO THE STRONG SURFACE HIGH
ENTRENCHED OVER THE FLORIDA PENINSULA AND OFF THE SOUTHEAST
COAST. CLOUDY CONDITIONS ARE IN PLACE NEAR AND SOUTHEAST OF THIS
FRONT. MULTIPLE SHORTWAVES ARE FORECAST TO MOVE EAST THROUGH 700
MB FLOW AHEAD OF THE DYING FRONT THIS MORNING INTO THE AFTERNOON
HOURS. MOISTURE AND LIFT ASSOCIATED WITH THESE FEATURES WILL HELP
KEEP CLOUD COVER IN PLACE THROUGH THE DAY INTO THE EVENING. THIS
WILL HELP KEEP HIGHS IN THE UPPER 50S TO LOWER 60S.
A SECOND STRONGER COLD FRONT IS MORE QUICKLY MOVING SOUTHEAST
INTO THE CENTRAL GREAT LAKES REGION. THIS FRONT WILL EVENTUALLY
PUSH SOUTHEAST AND OVERTAKE THE WEAKENING SOUTHERN FRONTAL
BOUNDARY. AS THIS SECONDARY FRONT OVERTAKES THE SOUTHERN FRONTAL
BOUNDARY, MUCH STRONGER FORCING DEVELOPS ALOFT AHEAD OF THE NEWLY
STRENGTHENED FRONT THIS EVENING. THIS IS DUE IN A LARGE PART TO
LOW AND MID-LEVEL JETS THAT INCREASE AHEAD OF IT (850 MB JET TO
40 KTS/500 MB JET 50-60 KTS). STRONG SHEAR (0-6KM) AND HELICITY
DEVELOP AS WELL. LUCKILY, MOST GUIDANCE SHOWS VERY MEAGER ELEVATED
CAPE DEVELOPING (<300 J/KG). EXPECT MAINLY LIGHT SHOWERS WITH
MAYBE AN ELEVATED THUNDERSTORM DEVELOPING THROUGH MUCH OF THE
EVENING HOURS AS THE SOUTHERN EDGE OF THIS STRONG FORCING MOVES
SOUTH INTO THE AREA.
SHORT TERM
(THURSDAY THROUGH SATURDAY)
ISSUED AT 1020 AM CST WED FEB 25 2026
HOWEVER, CONFIDENCE IN HEAVIER RAINFALL AND MORE WIDESPREAD
ELEVATED THUNDERSTORM POTENTIAL IS MEDIUM TO HIGH TOWARDS
DAYBREAK INTO THE MORNING HOURS ON THURSDAY. GIVEN THE ELEVATED
AND WEAK NATURE OF THE INSTABILITY, DESPITE SOME MID LEVEL LAPSE
RATES AROUND 7.0 DEGREES AND THE STRONG SHEAR, NO STRONG TO SEVERE
THUNDERSTORM ACTIVITY IS EXPECTED. THE HEAVIEST RAINFALL AMOUNTS
BETWEEN 0.50 AND 0.75 INCHES ARE EXPECTED NEAR AND NORTH OF THE
TENNESSEE RIVER THROUGH THURSDAY.
THE MAIN FRONTAL BOUNDARY SHIFTS FURTHER SOUTH DURING THE EARLY
AFTERNOON HOURS ON THURSDAY. EXPECT THE HEAVIEST RAINFALL TO SHIFT
EAST AND SOUTH OF THE AREA. HOWEVER, LIGHT RAIN AND MAYBE A
THUNDERSTORM OR TWO COULD LINGER INTO AT LEAST THE EARLY EVENING
HOURS AND POSSIBLY LATER, DEPENDING ON WHERE THE FRONT STALLS
SOUTH OF THE AREA, BEFORE A DRIER CLIPPER SYSTEM PUSHES SOUTHEAST.
THIS CLIPPER SYSTEM SHOULD DRIVE THE FRONT INTO SOUTHERN ALABAMA
AND THE FLORIDA PANHANDLE LATE THURSDAY NIGHT INTO EARLY FRIDAY
MORNING. DESPITE CLOUD COVER AND RAINFALL, HIGHS SHOULD STILL BE
ABLE TO REACH THE MID TO UPPER 60S ON THURSDAY GIVEN STRONG LOW
LEVEL WARM AIR ADVECTION AHEAD OF THE FRONT.
SOME DRIER AIR WILL PUSH INTO THE AREA ON FRIDAY. HIGHS DESPITE
SOME ABUNDANT SUNSHINE SHOULD BE WARM, BUT STILL ONLY CLIMB INTO
THE MID TO UPPER 60S. UPPER LEVEL FLOW TURNS MORE ZONAL FRIDAY
NIGHT INTO SATURDAY, AS ANOTHER COLD FRONT PUSHES SOUTHEAST
TOWARDS THE TENNESSEE VALLEY. CONCENTRATED CLOUD COVER SHOULD
REMAIN WELL NORTH OF THE AREA THROUGH MUCH OF THE DAY ON SATURDAY.
925 MB TEMPERATURES INCREASE SIGNIFICANTLY IN MODEL GUIDANCE TO
BETWEEN 10 AND 15 DEGREES. GIVEN SOUTHWEST SURFACE FLOW SHOWN IN
MODELS AHEAD OF THE FRONT AND THE ABUNDANT SUNSHINE EXPECTED,
HIGHS SHOULD JUMP A BIT INTO THE UPPER 60S TO LOWER 70S AT LEAST.
THIS MAY BE A TAD COOL GIVEN FACTORS JUST MENTIONED.
LONG TERM
(SATURDAY NIGHT THROUGH TUESDAY)
ISSUED AT 1014 PM CST TUE FEB 24 2026
POST-FRONTAL, DRY CONDITIONS ARE FORECAST TO DOMINATE THE WEEKEND
WITH HIGHS RISING INTO THE 70S AND OVERNIGHT LOWS IN THE 40S. THESE
TEMPERATURES ARE AROUND 10 DEGREES ABOVE NORMAL FOR THIS TIME OF
YEAR. AS AN UPPER LEVEL SHORTWAVE APPROACHES FROM THE WEST EARLY NEXT
WEEK, LOW RAIN CHANCES (15-30%) RETURN SUNDAY NIGHT THROUGH TUESDAY.
DUE TO SOME DISAGREEMENT IN TIMING, HAVE CONTINUED WITH BLENDED
GUIDANCE FOR NOW. IF YOU HAVE OUTDOOR INTERESTS EARLY NEXT WEEK, BE
SURE TO STAY TUNED FOR UPDATES AS WE APPROACH THE WEEKEND.
