SHORT TERM
/ISSUED 155 AM CDT MON MAY 5 2025/
/THROUGH TUESDAY AFTERNOON/
A BUSY PERIOD OF ACTIVE WEATHER IS EXPECTED TO BEGIN TODAY, WITH
THE POTENTIAL FOR STRONG TO SEVERE THUNDERSTORMS AND LOCALLY HEAVY
RAINFALL THROUGH TUESDAY AFTERNOON AS AN UPSTREAM TROUGH PIVOTS
THROUGH THE DESERT SOUTHWEST. AS FOR TONIGHT, WE REMAIN RAIN-FREE
WITH SOME CLOUDS ASSOCIATED WITH THE STORMS THAT DEVELOPED IN THE
TRANS-PECOS REGION MOVING ACROSS THE REGION THIS MORNING. MORNING
LOWS WILL BE A FEW TO SEVERAL DEGREES WARMER THAN YESTERDAY, BUT
STILL BELOW NORMAL FOR EARLY MAY.
BY SUNRISE, THE SURFACE HIGH PRESSURE WILL STILL BE LINGERING
NEARBY BUT SHOULD HAVE SHIFTED FAR ENOUGH EAST TO ALLOW RETURN
FLOW TO BECOME MORE FIRMLY ESTABLISHED ACROSS NORTH AND CENTRAL
TEXAS. STRENGTHENING SOUTHWESTERLY FLOW ALOFT WILL ALSO ALLOW FOR
A NOTABLE UPTICK IN MID AND UPPER-LEVEL MOISTURE ACROSS THE STATE,
AIDED BY A 100–120 KT JET STREAK ROUNDING THE BASE OF THE UPPER
TROUGH. THE NET RESULT WILL BE DEWPOINTS RISING INTO THE MID 50S
TO MID 60S, WITH INCREASING MID-LEVEL CLOUD COVER AS ISENTROPIC
ASCENT STRENGTHENS FROM WEST TO EAST. ELEVATED SHOWERS AND A FEW
THUNDERSTORMS ARE EXPECTED TO DEVELOP TO OUR WEST EARLY THIS
MORNING, WITH ACTIVITY TRACKING INTO THE WESTERN PORTIONS OF THE
FORECAST AREA SHORTLY AFTER DAYBREAK, AND SPREADING EAST OF THE
I-35 CORRIDOR BY THE EARLY AFTERNOON. THIS INITIAL ROUND OF
CONVECTION IS NOT EXPECTED TO BE SEVERE, AS IT WILL LARGELY BE
ELEVATED IN NATURE, DRIVEN BY STRONG UPGLIDE ATOP A RELATIVELY DRY
BOUNDARY LAYER.
LATER IN THE DAY, STRONG DIURNAL HEATING ACROSS THE PERMIAN BASIN
WILL STEEPEN LAPSE RATES AND PROMOTE MODERATE DESTABILIZATION
ALONG AND JUST EAST OF THE DRYLINE. WHILE THE LOW-LEVEL INSTABILITY
AXIS MAY REMAIN RATHER NARROW AND CONFINED TO AREAS IMMEDIATELY
NEAR THE DRYLINE, DEEP-LAYER SHEAR AND SYNOPTIC ASCENT SHOULD BE
SUFFICIENT TO SUPPORT THE DEVELOPMENT OF DISCRETE CONVECTION
ACROSS WEST TEXAS LATE THIS AFTERNOON AND THROUGH THE EVENING,
WITH SOME POTENTIAL FOR UPSCALE GROWTH INTO LARGER CLUSTERS OR A
FORWARD-PROPAGATING MCS.
ANY ORGANIZED CONVECTION THAT DEVELOPS WEST OF THE AREA THIS
EVENING AND TONIGHT WILL SPREAD EASTWARD INTO THE BIG COUNTRY AND
WESTERN NORTH/CENTRAL TEXAS EARLY TUESDAY. A WEAK SURFACE LOW
DEVELOPING OVER FAR SOUTHWEST TEXAS AND A GRADUALLY LIFTING WARM
FRONT WILL ENHANCE LOW-LEVEL MASS RESPONSE AND CONTINUE MOISTURE
ADVECTION ACROSS THE REGION THROUGH THE OVERNIGHT HOURS. HOWEVER,
THE SEVERE THREAT SHOULD DIMINISH WITH EASTWARD EXTENT DUE TO
NOCTURNAL STABILIZATION AND A CONTINUED LACK OF SURFACE-BASED
INSTABILITY. THAT SAID, ELEVATED INSTABILITY MAY INCREASE
MARKEDLY TONIGHT, PARTICULARLY NORTH OF THE WARM FRONT INTO
CENTRAL TEXAS WHERE STRONG LOW-LEVEL MOISTURE TRANSPORT BENEATH
STEEPENING MID-LEVEL LAPSE RATES WILL SUPPORT MODERATE MUCAPE.
FORECAST SOUNDINGS SHOW ELONGATED, CURVED HODOGRAPHS BENEATH THE
STRENGTHENING LLJ, SUGGESTING A CONDITIONAL RISK FOR A DAMAGING
WIND AND LARGE HAIL THREAT WITH ANY ELEVATED CELLS OR CLUSTERS
THAT PERSIST OVERNIGHT.
BY TOMORROW MORNING, WIDESPREAD SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO BE ONGOING ACROSS MUCH OF NORTH AND CENTRAL TEXAS AS A
POTENT SHORTWAVE EJECTS FROM THE BASE OF THE UPPER TROUGH AND
TRAVERSES THE SOUTHERN PLAINS. THIS WILL PLACE THE REGION BENEATH
STRONG SYNOPTIC-SCALE ASCENT, COINCIDING WITH ANOMALOUSLY STRONG
LOW LEVEL MOISTURE TRANSPORT. PWAT VALUES OF 1.3–1.8" WILL ALSO
PLACE THE REGION ABOVE THE 90TH PERCENTILE OF LOCAL SOUNDING
CLIMATOLOGY, SETTING THE STAGE FOR HEAVY RAINFALL POTENTIAL IN
ADDITION TO A CONTINUED SEVERE WEATHER THREAT. FORECAST CONFIDENCE
DECREASES SOMEWHAT HEADING INTO TUESDAY AFTERNOON, WITH STORM
MODE AND SEVERITY LARGELY DEPENDENT ON THE EXTENT OF EARLY-DAY
CONVECTION AND ASSOCIATED CLOUD COVER. IF STORMS PERSIST INTO THE
LATE MORNING AND EARLY AFTERNOON, WIDESPREAD RAINFALL COULD LIMIT
SURFACE-BASED INSTABILITY, ESPECIALLY ACROSS NORTH TEXAS. HOWEVER,
THE LIFTING WARM FRONT SHOULD ALLOW THE WEAKLY CAPPED, MOIST WARM
SECTOR TO BUILD NORTHWARD ACROSS CENTRAL TEXAS THROUGH MIDDAY. IF
ENOUGH DESTABILIZATION OCCURS SOUTH OF THIS BOUNDARY, ADDITIONAL
STRONG TO SEVERE THUNDERSTORMS WILL BE POSSIBLE THROUGH THE
AFTERNOON, PARTICULARLY ALONG AND SOUTH OF THE WARM FRONT. IN THIS
SCENARIO, ALL SEVERE HAZARDS WILL BE POSSIBLE, ESPECIALLY WHERE
BOUNDARY INTERACTIONS (E.G., OUTFLOW BOUNDARIES FROM MORNING
CONVECTION OR WARM FRONT) LOCALLY ENHANCE LOW-LEVEL SHEAR AND
LIFT.
NORTH OF THE WARM FRONT, CONVECTION WOULD REMAIN ELEVATED, BUT A
CONTINUED HAIL THREAT IS LIKELY TO PERSIST. IN ADDITION TO SEVERE
WEATHER, FLOOD CONCERNS MAY INCREASE TUESDAY, PARTICULARLY EAST OF
THE I-35 CORRIDOR WHERE THE HIGHEST QPF IS FOCUSED. RAINFALL
TOTALS WILL MOST LIKELY RANGE FROM 1–3" ACROSS THE REGION, WITH
LOCALLY HIGHER AMOUNTS POSSIBLE WHERE CONVECTIVE TRAINING OCCURS.
THE FLOOD RISK IS COMPOUNDED BY RECENT RAINFALL IN SOME AREAS,
WHICH WILL LOWER THE THRESHOLD FOR LOCALIZED FLASH FLOODING.
OTHERWISE, GUIDANCE CONTINUES TO FAVOR A FAIRLY RAPID CLEARING OF
CONVECTION FROM WEST TO EAST TUESDAY AFTERNOON BRINGING A SWIFT
END TO THIS PERIOD OF ACTIVE WEATHER.

LONG TERM
/NEW/
/TUESDAY EVENING THROUGH THE WEEKEND/
RAIN CHANCES WILL CONTINUE EACH DAY THROUGH FRIDAY WITH AN UNSETTLED
PATTERN STICKING AROUND, FOLLOWED BY DRIER WEATHER THIS WEEKEND
INTO EARLY NEXT WEEK. NEAR OR SLIGHTLY BELOW TEMPERATURES ARE
EXPECTED TO PREVAIL WITH HIGHS IN THE 70S/LOW 80S AND OVERNIGHT
LOWS MOSTLY IN THE 50S.
TUESDAY'S ACTIVITY WILL BE EXITING EAST BY THE EVENING HOURS WITH
SOME LINGERING RAIN/STORM CHANCES ACROSS EAST TEXAS, BUT IT
SHOULD BE A QUIET NIGHT OVERALL IN THE WAKE OF THE EARLIER, MORE
ACTIVE WEATHER. FOR WEDNESDAY, LOW RAIN CHANCES WILL LINGER ACROSS
CENTRAL TEXAS (20-40%) AND ALONG THE RED RIVER (20%), BUT MOST
AREAS WILL STAY DRY. THE WEAK FRONTAL BOUNDARY AND PLENTY OF
REMAINING MOISTURE WILL BE SITUATED TO THE SOUTH, TOWARDS THE GULF
COAST ON WEDNESDAY. COVERAGE SHOULD REMAIN LOW, BUT THIS COULD
ALLOW FOR A FEW SHOWERS AND STORMS TO DEVELOP PRIMARILY IN THE
SOUTHERN HALF OF CENTRAL TEXAS, WITH THE BETTER CHANCES REMAINING
OUTSIDE OF THE FORECAST AREA. CONDITIONS ARE NOT OVERLY FAVORABLE
FOR SEVERE WEATHER, BUT THERE MAY ALSO BE A STRONG STORM OR TWO IF
SOMETHING DEVELOPS. WITH THE SLOW MOVEMENT OF THE UPPER TROUGH
THROUGH THE SOUTHERN PLAINS AND REMAINING MOISTURE ACROSS THE
REGION, THE RED RIVER ALSO HAVE LINGERING POPS ON WEDNESDAY AS
ADDITIONAL MOISTURE WRAPS AROUND THE LOW PRESSURE SYSTEM ACROSS
OK/KS.
BETTER RAIN CHANCES FOR THE RED RIVER AND FARTHER SOUTH THROUGH
NORTH TEXAS WILL EXIST ON THURSDAY AND FRIDAY (~30-50% BOTH DAYS),
BUT THERE REMAINS UNCERTAINTY IN WHEN THE ALMOST ENTIRELY CUTOFF,
WEAKENING UPPER LOW WILL FINALLY BE ABSORBED INTO THE NORTHERN
STREAM FLOW AND SHUNTED FURTHER EASTWARD. REGARDLESS, ADDITIONAL
CHANCES FOR SHOWERS AND STORMS RETURN TO END THE WEEK AS EMBEDDED
DISTURBANCES ROUND THE BASE OF UPPER TROUGH IN THE NW FLOW ALOFT,
WHICH WILL RESULT IN ADDITIONAL LIFT OVERHEAD PARTICULARLY
LATE WEDNESDAY NIGHT INTO THURSDAY AND POTENTIALLY AGAIN FRIDAY.
BETTER INSTABILITY LOOKS TO DEVELOP THURSDAY, WITH MORE NOTABLE
MOISTURE AVAILABLE TO WORK WITH AS WELL. WHILE NOT IMPRESSIVE BY
ANY MEANS, WE WILL HAVE TO MONITOR THE POTENTIAL FOR SEVERE
WEATHER DURING THIS TIME AS THERE IS A LOW CHANCE FOR STRONG TO
MARGINALLY SEVERE STORMS WITH THIS ACTIVITY.
APART FROM THE LINGERING RAIN CHANCES, THE SLOW TRANSITION OF THE
UPPER TROUGH WILL MAKE TEMPERATURES SLOW TO MODERATE ACROSS THE
REGION. DFW'S NORMAL HIGH TEMPERATURE MAY 7TH-11TH IS 81-82 DEGREES,
AND THE CURRENT FORECAST IS FOR HIGHS TO BE ABOUT 5 TO 6 DEGREES
BELOW THAT THROUGH THE WEEKEND, BEFORE FINALLY STARTING TO CLIMB
BACK INTO THE 80S. FOR WACO, THE NORMAL HIGH TEMPERATURE IS 83-84
DURING THIS TIMEFRAME, AND THE FORECAST HAS ACT SIMILARLY AROUND
5 TO 7 DEGREES COOLER DURING THIS TIME. NOT THE MOST RIVETING
TIDBIT OF INFORMATION, BUT WE WILL TAKE WHAT WE CAN GET SINCE
ABOVE NORMAL TEMPERATURES ARE FAVORED FOR THE LATTER HALF OF THE
MONTH, AND SUMMER WILL ALSO BE HERE BEFORE WE KNOW IT.

AVIATION
/ISSUED 155 AM CDT MON MAY 5 2025/
/06Z TAFS/
VFR CONDITIONS PREVAIL WITH CLOUD COVER LIMITED TO THE REMNANTS
OF CONVECTION THAT DEVELOPED OVER WEST TEXAS EARLIER. SCATTERED
HIGH-BASED SHOWERS AND A FEW EMBEDDED THUNDERSTORMS WILL BEGIN TO
SPREAD TOWARDS D10 LATER THIS MORNING, REACHING WACO AROUND 16Z
AND THE METROPLEX TERMINALS CLOSER TO 19Z. THE MAIN WINDOW IN
WHICH WE EXPECT INFREQUENT LIGHTNING STRIKES TO MOVE ACROSS THE
AREA WILL BE DURING THE AFTERNOON AND EARLY EVENING (22-02Z) AMID
STEEPENING MID-LEVEL LAPSE RATES. CONFIDENCE IN DIRECT IMPACTS TO
THE TAF SITES IS TOO LOW TO INCLUDE ANY MENTION OF TSRA GIVEN THE
EXPECTED SCATTERED COVERAGE AS THIS ACTIVITY MOVES THROUGH THE
REGION. INTERMITTENT LIGHT SHOWERS WILL CONTINUE THROUGH THE END
OF THE CURRENT TAF PERIOD. OTHERWISE, CLOUD BASES WILL STEADILY
LOWER THROUGHOUT THE DAY TODAY WITH MVFR CIGS SPREADING IN FROM
THE WEST AFTER 00Z. IFR CIGS AND MORE WIDESPREAD CONVECTION ARE
EXPECTED AFTER 12Z TUESDAY AND WILL BE INTRODUCED TO THE TAFS IN
LATER UPDATES.
