KEY MESSAGES
- WIDESPREAD RAIN ALONG WITH ISOLATED THUNDERSTORMS ARE ONGOING
ACROSS NORTH AND CENTRAL TEXAS. SEVERE WEATHER IS NOT EXPECTED.
- A THREAT FOR MORE TYPICAL SPRING TIME SEVERE WEATHER MAY EVOLVE
LATE THIS WEEK INTO THE WEEKEND.
SHORT TERM
(TODAY THROUGH WEDNESDAY)
ISSUED AT 1234 AM CDT TUE APR 21 2026
RAIN SHOWERS ARE EXPECTED TO OVERSPREAD MUCH OF NORTH AND CENTRAL
TEXAS LATER TONIGHT INTO TUESDAY MORNING AS LARGE SCALE ASCENT
INCREASES AHEAD OF A MID-LEVEL SHORTWAVE EXITING THE TRANS-PECOS
REGION. MOST OF THIS SHOWER ACTIVITY WILL REMAIN ACROSS CENTRAL
TEXAS UNTIL THE LOWER LEVELS OF THE ATMOSPHERE SATURATE CLOSER TO
THE I-20 CORRIDOR ALLOWING FOR MORE WIDESPREAD COVERAGE ACROSS
NORTH TEXAS BY 3-4AM EARLY TUESDAY MORNING. IT WILL BE A SOGGY
TUESDAY MORNING COMMUTE ACROSS MUCH OF THE REGION WITH A FEW
EMBEDDED THUNDERSTORMS NOT ENTIRELY OUT OF THE REALM OF
POSSIBILITY DURING THE MORNING HOURS AS THIS ACTIVITY WILL STILL
HAVE ACCESS TO A FEW HUNDRED J/KG OF MUCAPE.
THIS BROAD PRECIPITATION SHIELD WILL LARGELY DIMINISH AND SHIFT
EAST OF OUR AREA BY TUESDAY EVENING, BUT ISOLATED TO SCATTERED
SHOWERS MAY LINGER INTO TUESDAY NIGHT, ESPECIALLY ALONG AND EAST
OF I-35. WHEN ALL IS SAID AND DONE, THE MOST LIKELY RAINFALL
TOTALS WILL FALL IN THE 0.5-1.25" RANGE ACROSS CENTRAL TEXAS AND
0.25-0.75" RANGE ACROSS NORTH TEXAS. SOME OF THE MORE RECENT HIGH-
RESOLUTION GUIDANCE IS SUGGESTING THAT THE DAYBREAK ACTIVITY NEAR
THE I-20 CORRIDOR MAY BE A LITTLE BIT HEAVIER THAN CURRENTLY
FORECAST, SO LOCALIZED TOTALS OF 1+" IN THE METROPLEX AND
SURROUNDING COLLAR COUNTIES REMAIN POSSIBLE THROUGH TUESDAY
EVENING. WIDESPREAD, DENSE LOW-LEVEL CLOUD COVER AND RAIN-COOLED
AIR WILL KEEP AFTERNOON HIGHS DOWN IN THE LOW TO MID 60S TUESDAY.
ALTHOUGH WEAK MID-LEVEL RIDGING WILL MOVE IN BEHIND THE SHORTWAVE
WEDNESDAY, DEEP MOISTURE WILL STILL SUPPORT ISOLATED TO SCATTERED
SHOWER ACTIVITY LARGELY ALONG AND EAST OF I-35 WEDNESDAY AFTERNOON
AND EVENING. CLOUDS WILL FINALLY SCATTER OUT WEDNESDAY AFTERNOON
AS WELL ALLOWING FOR TEMPERATURES TO RISE INTO THE 70S ACROSS MUCH
OF NORTH AND CENTRAL TEXAS.
LONG TERM
(THURSDAY THROUGH MONDAY)
ISSUED AT 1234 AM CDT TUE APR 21 2026
A SHARP DRYLINE WILL SET UP TO OUR WEST BY THURSDAY WITH A WARM
AND MOIST AIRMASS REMAINING OVERHEAD MUCH OF NORTH AND CENTRAL
TEXAS. WITH PERSISTENT EMBEDDED SHORTWAVES IN THE WEST-
SOUTHWESTERLY FLOW ALOFT, WE COULD SEE PERIODIC CHANCES FOR
ISOLATED TO SCATTERED DRYLINE THUNDERSTORMS DURING THE LATTER HALF
OF THIS WEEK. A MAJOR LIMITING FACTOR TO THUNDERSTORM DEVELOPMENT,
ESPECIALLY THURSDAY AFTERNOON AND EVENING, WILL BE A STOUT CAPPING
INVERSION NEAR 800MB. THE BETTER LARGE-SCALE LIFT WILL ALSO REMAIN
NORTH OF OUR FORECAST AREA ON THURSDAY, SO WE WILL KEEP THE
POTENTIAL FOR AN ISOLATED THUNDERSTORM OR TWO TO 10% FOR LATE
THURSDAY ACROSS OUR WEST.
THUNDERSTORM CHANCES WILL BE SLIGHTLY HIGHER FRIDAY AFTERNOON AND
EVENING ACROSS THE EASTERN HALF OF OUR FORECAST AREA AS THE
DRYLINE PUSHES TOWARD THE I-35 CORRIDOR AND A WEAK COLD FRONT
NEARS THE RED RIVER. WARM-ADVECTION SHOWERS WILL BE POSSIBLE EARLY
IN THE AFTERNOON, BUT MORE ROBUST CONVECTIVE INITIATION MAY HOLD
OFF UNTIL AFTER 4-5PM WHEN FORECAST SOUNDINGS SUGGEST THE CAP MAY
BREAK. STRONG INSTABILITY AND FAVORABLE DEEP-LAYER SHEAR WILL
SUPPORT A LARGE HAIL AND DAMAGING WIND THREAT IN ANY STORMS THAT
DEVELOP LATE FRIDAY AFTERNOON AND EVENING WITH THE GREATEST THREAT
GENERALLY ALONG/EAST OF I-35 AND ALONG/NORTH OF I-20. THIS ACTIVE
PATTERN WILL CONTINUE INTO THE WEEKEND WITH INCREASING
PROBABILITIES FOR THUNDERSTORMS, SOME STRONG TO SEVERE, ACROSS THE
EASTERN HALF OF OUR FORECAST AREA LATE SATURDAY INTO SUNDAY.
