DISCUSSION
(SATURDAY THROUGH NEXT FRIDAY)
ISSUED AT 1044 PM CDT FRI APR 17 2026
ANOTHER FAIR AND WARM DAY IS EXPECTED TODAY, WITH AFTERNOON HIGHS
CLIMBING INTO THE MID-80S. THANKFULLY, THIS PATTERN WILL FINALLY
BEGIN TO BREAK DOWN BY THE EVENING HOURS, AS RAIN CHANCES BEGIN
TO INCREASE AHEAD OF THE COLD FRONT. THE BAD NEWS IS, RAINFALL
AMOUNTS STILL LOOK MEAGER AT BEST, WITH AMOUNTS GENERALLY RANGING
BETWEEN 0.25 AND 0.5 INCHES THROUGH SUNDAY MORNING.
TEMPERATURES STILL LOOK TO DROP SOME 15-20 DEGREES BEHIND THE COLD
FRONT, WITH AFTERNOON HIGHS ON SUNDAY RANGING IN THE UPPER-60S AND
LOW-70S. GIVEN THE STIFF WINDS BEHIND THE FRONT, AND VERY LOW RH
VALUES, WE MAY PUSH RED FLAG WARNING CRITERIA IS SOME LOCATIONS.
HOWEVER, THAT WILL NEED FURTHER TUNING THROUGH THE DAY TOMORROW.
OTHERWISE, THE REST OF THE WEEK IS "MORE OF THE SAME" AS A SLIGHT
RIDGE BUILDS BACK INTO THE AREA. AFTERNOON HIGHS WILL BEGIN TO
CLIMB, REACHING THE MID-80S ONCE MORE COME THURSDAY, AND THE ONLY
CHANCE FOR RAIN APPEARING TO BE NEXT WEEKEND.
