WX MAP CURRENTLY HAS ARE AREA OF WEAKENING HIGH PRESSURE MOVING INTO
THE SECOUS. MEANWHILE A WEAK SURFACE TROUGH IS ORGANIZING OVER
OKLAHOMA AND GRADUALLY DEEPENING EAST TOWARD THE TENNESSEE VALLEY.
LOCALLY, CONDITIONS WILL REMAIN WARM AND DRY WITH THE STRONGER
MOISTURE CONVERGENCE WELL TO OUR NORTH. THIS TROUGH WILL DRAW UPON
GULF MOISTURE BY MONDAY AND ADVECT MORE AMBIENT MOISTURE ACROSS THE
FORECAST AREA. THAT SAID, DRY LAYERS BETWEEN 1-3KM ALOFT WILL LIKELY
CAP BUILDING CUMULUS CLOUDS FROM DEVELOPING PRECIPITATION.
AS THE PRESSURE GRADIENT TIGHTENS WITH THE NEAR STATIONARY TROUGH
ACROSS THE OZARKS AND TENNESSEE VALLEY WHILE ABUTTING THE HIGH
PRESSURE OVER FLORIDA, SOUTHERLY WINDS WILL INCREASE FURTHER ON
TUESDAY. NOT LOOKING AT HAZARDOUS WINDS, BUT FREQUENT GUSTS AROUND
20-25MPH ARE LIKELY. WHILE RAINFALL IS NIL IN THE SHORT TERM, ONE
BIT OF GOOD NEWS RELATED TO FIRE WEATHER IS THAT DIURNAL RH MINS ARE
EXPECTED TO RISE MONDAY AND TUESDAY AMID ABOVE NORMAL HIGHS IN THE
UPPER 70S TO LOW 80S.

LONG TERM
(WEDNESDAY THROUGH SUNDAY)
ISSUED AT 1203 AM CST SUN MAR 1 2026
BY WEDNESDAY, THE LOCAL PRESSURE GRADIENT SLACKENS ALLOWING GUSTS TO
COME DOWN A BIT. THE AFOREMENTIONED STATIONARY TROUGH QUICKLY BEGINS
TO EVOLVE / RETROGRADE WEST OVER NORTHERN TEXAS. WHILE THAT REGION
IS MORE FAVORABLE FOR PRECIPITATION, LOCALLY, THE COLUMN BEGINS TO
MOISTEN WITH IMPROVING LOW LEVEL PROFILES TO SUPPORT ISOLATED
SHOWERS OR WEAK THUNDERSTORMS.
FROM HERE ON OUT THROUGH THE REMAINDER OF THE LONG TERM, THE
FORECAST PATTERN BECOMES A BIT UNSETTLED WITH RESPECT TO RAINFALL.
THE KNOWN IS THAT GULF MOISTURE AND ABOVE NORMAL TEMPERATURES WILL
BEGIN TO SUPPORT ISOLATED TO SCATTERED CHANCES OF RAINFALL DURING
THE LATER HALF OF THE WORK WEEK. THE MAIN CAVEAT IS THAT THE ACTIVE
JET AND ASSOCIATED PERTURBATIONS MEANDER NORTH OF THE FORECAST AREA
INTO THE OHIO VALLEY. AN UPSTREAM UPPER SHORTWAVE IS FORECAST TO
OVER THE SW US. GUIDANCE HAS BEEN SUPPORTIVE OF PULLING DOWN THE
AREA OF BETTER MOISTURE CONVERGENCE TOWARD THE COAST INTO THE
UPCOMING WEEKEND. THEREFORE POPS DO INCREASE NOTABLY BY SATURDAY FOR
THE POTENTIAL OF WIDESPREAD CHANCES. WORTH NOTING, THE CURRENT CPC
OUTLOOK KEEPS THE FORECAST ARE TRENDING ABOVE NORMAL FOR
PRECIPITATION IN THE 6-10 DAY WINDOW SUGGESTING OPPORTUNITIES OF A
MUCH NEED RAINFALL MAY INCREASE THROUGH THE END OF THE FIRST WEEK OF
MARCH.
