DISCUSSION
ISSUED AT 1205 AM CDT MON APR 20 2026
SOME MIGHT CALL THIS MORNING A CHILLY ONE, AS TEMPERATURES START
OUT IN THE MID 40S ACROSS THE REGION. AFTERNOON HIGHS TODAY WILL
RANGE FROM THE LOWER TO UPPER 70S, WITH A FEW LOCATIONS IN NORTH
CENTRAL LOUISIANA FLIRTING WITH THE 80 DEGREE MARK. NONETHELESS,
STILL PLEASANT FOR THIS TIME OF THE YEAR. AN UPPER-LEVEL
DISTURBANCE WILL MOVE ACROSS TEXAS ON MONDAY NIGHT AND WILL BRING
A RETURN OF PRECIPITATION CHANCES, MAINLY ACROSS OUR WESTERN
ZONES. WITH THE RAIN AND CLOUD COVER EXPECTED ON TUESDAY, WE WILL
SEE A WIDE VARIETY OF AFTERNOON TEMPERATURES. THOSE WITH
PRECIPITATION AND CLOUD COVER, MAINLY OUR WESTERN HALF OF THE
FORECAST AREA, WILL SEE HIGHS IN THE MID TO UPPER 60S, WHILE THE
EASTERN HALF WILL RANGE FROM THE LOWER TO UPPER 70S. NOT EXPECTING
MUCH IN THE WAY OF RAIN AMOUNTS ON TUESDAY, BUT THE HIGHER AMOUNTS
WILL BE ACROSS OUR FAR WESTERN ZONES FROM WOOD COUNTY SOUTH
THROUGH CHEROKEE COUNTY. WHILE THERE WILL BE A BRIEF BREAK IN
PRECIPITATION CHANCES TUESDAY EVENING INTO EARLY TUESDAY NIGHT,
THEY WILL BEGIN TO INCREASE EARLY WEDNESDAY MORNING AS THE
AFOREMENTIONED DISTURBANCE PUSHES EAST. RAIN CHANCES COULD EXTEND
FURTHER TO THE EAST WITH THIS PUSH.
THURSDAY RAIN CHANCES WILL EXIST, BUT WILL BE MUCH LOWER THAN ON
TUESDAY AND WEDNESDAY. IN ADDITION, TEMPERATURES WILL BEGIN TO
INCREASE, WITH LOWER TO MID 80S RETURNING TO MOST OF THE AREA.
WATCHING THE POTENTIAL FOR SOME MORE WIDESPREAD SHOWERS AND
THUNDERSTORMS POSSIBLE ON FRIDAY, SATURDAY AND SUNDAY. MODELS ARE
STILL SHOWING SOME MAJOR DISAGREEMENT IN TIMING, LOCATION AND
INTENSITY BUT IT WILL BE WORTH WATCHING HOW MODELS TREND OVER THE
NEXT COUPLE DAYS. SPC DID DROP A D6 (FRIDAY) SLIGHT RISK ACROSS
MUCH OF OUR REGION. I WOULDN'T SAY CONFIDENCE IS HIGH IN THIS
POTENTIAL, BUT SOMETHING THAT WILL NEED TO BE MONITORED
NONETHELESS SO CONTINUE TO CHECK THE FORECAST FOR UPDATES. /33/
