MESOSCALE UPDATE
ISSUED AT 633 PM CDT TUE MAR 17 2026
THE NEAR-TERM FORECAST WAS UPDATED THROUGH THE DAYTIME TOMORROW
BASED ON LATEST GUIDANCE. NO SIGNIFICANT CHANGES WERE NEEDED. ON
THE BACK SIDE OF A DEPARTING SURFACE HIGH, LIGHT WINDS ARE
EXPECTED OVERNIGHT. SOUTHERLY RETURN FLOW IS ALREADY BEGINNING
OVER NORTHEAST LOUISIANA, SOUTHEAST ARKANSAS, AND INTO THE
MISSISSIPPI DELTA REGION. OTHERWISE, THE LIGHT WINDS ACROSS
MISSISSIPPI SHOULD ALLOW MOST LOCATIONS TO RADIATE WELL OVERNIGHT
AND DROP TO NEAR OR BELOW FREEZING. /NF/
DISCUSSION
ISSUED AT 115 PM CDT TUE MAR 17 2026
TONIGHT THROUGH NEXT MONDAY...UNDER CONTINUED NORTHWEST FLOW ALOFT,
HIGH PRESSURE AT THE SURFACE IS SETTLING INTO THE REGION. ANOTHER
CHILLY NIGHT WILL PREVAIL ACROSS THE FORECAST AREA TONIGHT, BUT NOT
AS COLD AS LAST NIGHT. THIS IS THANKS IN LARGE PART TO A MID/UPPER
LEVEL DISTURBANCE PASSING TO OUR NORTH. THIS WILL RESULT IN
INCREASING CLOUD COVER OVER MAINLY CENTRAL AND NORTHERN PORTIONS OF
THE CWA OVERNIGHT.
ALTHOUGH TEMPERATURES WILL MODERATE UP, LOWS WEDNESDAY MORNING WILL
RANGE FROM THE LOWER 30S ACROSS THE EASTERN HALF OF THE FORECAST
AREA TO AROUND 40 ACROSS AREAS ALONG AND WEST OF THE MISSISSIPPI
RIVER. THIS, COUPLED WITH CALM WINDS, COULD LEAD TO SOME PATCHY
FROST FORMING, PARTICULARLY ACROSS EAST AND SOUTHEAST MISSISSIPPI.
HOWEVER, THE AFOREMENTIONED CLOUD COVER COULD PUT A HAMPER ON THIS.
WHERE EVER ANY FROST INDEED FORMS, IT COULD ONCE AGAIN RESULT IN
SOME MINOR DAMAGE TO SENSITIVE AND UNPROTECTED VEGETATION.
THE WEATHER OVERALL REMAINS QUIET THIS WEEKEND INTO EARLY NEXT WEEK.
TEMPERATURES WILL STEADILY REBOUND DURING THIS TIME, WITH HIGHS
EVENTUALLY CLIMBING BACK TO ABOVE NORMAL READINGS AND INTO THE 80S
SATURDAY THROUGH NEXT MONDAY. LOWS WILL LIKEWISE FOLLOW SUITE, BUT
REMAIN COOL THROUGH THE PERIOD. COME THIS WEEKEND INTO MONDAY
MORNING, LOWS TOO WILL BE ABOVE NORMAL AS THEY STRUGGLE TO FALL OUT
OF THE MIDDLE AND UPPER 50S. /19/
AVIATION

WILL BECOME LIGHT AND VARIABLE OVERNIGHT, TURNING OUT OF THE SOUTH
BY 15Z WEDNESDAY. /NF/
