- NO IMPACTFUL WEATHER IS FORECAST FOR THE NEXT 7 DAYS.
NEAR TERM
(TODAY)
ISSUED AT 438 AM CDT TUE APR 7 2026
WINDS CONTINUE TO BE CALM OR VERY LIGHT IN MANY AREAS ACROSS
NORTHERN ALABAMA AND SOUTHERN MIDDLE TENNESSEE. DEWPOINT
DEPRESSIONS ARE BETWEEN 0 AND 5 DEGREES IN MANY LOCATIONS.
HOWEVER, A COLD FRONT CURRENTLY PUSHING SOUTH INTO NORTHERN
ALABAMA FROM TENNESSEE WILL ADVECT DRIER AIR INTO THE AREA OVER
THE NEXT FEW HOURS. THIS SHOULD KEEP FOG FROM FORMING DESPITE THE
CLEAR SKIES.
A BIT WARMER TODAY WITH HIGHS EXPECTED TO CLIMB INTO THE UPPER 60S
TO LOWER 70S. BASED ON FORECAST SOUNDINGS, THINKING WE WILL SEE
DEWPOINTS DROP MORE THAN ENSEMBLE/NBM ARE THINKING. THE CURRENT
FORECAST DOES NOT DROP THEM LOW AS RAP13 OR HRRR, BUT LOWER THAN
ENSEMBLE GUIDANCE. THIS WILL ALLOW AFTERNOON RH VALUES TO DROP TO
BETWEEN 27 AND 30 PERCENT IN MANY AREAS. RAP13 AND HRRR SUGGEST A
BIT LOWER, MAYBE DROPPING AROUND OR JUST BELOW 25%.
NORTHEASTERLY WINDS BETWEEN 5 AND 10 MPH GUSTING TO BETWEEN 15 AND
20 MPH ARE EXPECTED. LUCKILY, RECENT RAINFALL SHOULD HELP
MITIGATE AND RED FLAG CONDITIONS. NOT EXPECTING THAT TO DEVELOP,
BUT MAY BE CLOSE BRIEFLY THIS AFTERNOON.
SHORT TERM
(TUESDAY NIGHT THROUGH THURSDAY)
ISSUED AT 1004 PM CDT MON APR 6 2026
THROUGH TUESDAY WINDS WILL VEER TO THE SE AS HIGH PRESSURE BUILDS
IN OVER THE NE COAST. THIS WILL PROMPT A SLOW BUT PROLONGED
PERIOD OF MOISTURE RETURN WITH DEW POINTS REBOUNDING TO THE MID
40S TO LOW 50S BY THURSDAY. ALOFT, A PASSING SHORT WAVE WILL
SUPPORT INCREASED CLOUD COVER WITH MOST OF THE DAY ON WEDNESDAY
BEING OVERCAST. THIS WILL MODERATE TEMPERATURES AND KEEP HIGHS IN
THE LOW 70S. DESPITE THE CLOUDS, MODELS INDICATE FAIRLY DRY AIR
NEAR THE SURFACE, KEEPING RAIN CHANCES BELOW 10% ON WEDNESDAY.
SKIES WILL CLEAR THROUGH THE DAY ON THURSDAY WITH WEAK WAA
CONTINUING FROM SE SURFACE FLOW ALLOWING FOR A WARM UP AS WE HEAD
INTO THE LONG TERM FORECAST.
LONG TERM
(THURSDAY NIGHT THROUGH MONDAY)
ISSUED AT 1004 PM CDT MON APR 6 2026
HIGH PRESSURE WILL PERSIST ACROSS THE SOUTHEAST AND MID ATLANTIC AT
THE END OF THE WEEK. AS A NORTHERN STREAM SYSTEM PUSHES OUT OF THE
GREAT LAKES AND INTO THE NORTHEAST ON SATURDAY, IT WILL SQUISH THE
HIGH PRESSURE OVER THE REGION. THE HIGH WILL BE STRONG ENOUGH TO
HOLD OFF THE APPROACHING COLD FRONT, KEEPING THE TN VALLEY DRY. THE
RIDGE WILL BUILD STRONGER OVER THE REGION ON SUNDAY, BEFORE A
SHORTWAVE GLIDES THROUGH AND DAMPENS IT ON MONDAY. REGARDLESS OF THE
FLUCTUATION OF THE RIDGE, SOUTHERLY WINDS WILL HELP PROVIDE A
GRADUAL INCREASE IN TEMPS THROUGH THE WEEKEND AND INTO NEXT WEEK. WE
WILL HOLD ONTO THE 70S FOR ONE MORE DAY ON FRIDAY BEFORE RETURNING TO
THE 80S OVER THE WEEKEND AND INTO NEXT WEEK. THE PARCHED SOIL WILL
NOT GET ANY RELIEF IN THE LONG TERM AS CONDITIONS WILL REMAIN DRY.
AVIATION
(06Z TAFS)
ISSUED AT 102 AM CDT TUE APR 7 2026
VFR CONDITIONS ARE EXPECTED THROUGHOUT THE TAF PERIOD AT BOTH
TERMINALS. THOUGH WINDS WILL BE LIGHT TONIGHT, DRIER AIR MOVING IN
FROM THE NE SHOULD KEEP ANY FOG AT BAY. WINDS WILL PICK UP FROM
THE NORTHEAST TO AROUND 10 KTS GUSTING TO 20 KTS AFTER 14Z.
