LONG TERM
(TONIGHT THROUGH SATURDAY)
ISSUED AT 251 AM CDT SUN MAY 4 2025
ANOTHER UNSEASONABLY COOL NIGHT IS IN STORE TONIGHT AS A
RELATIVELY DRY AIRMASS REMAINS IN PLACE ACROSS THE REGION.
ALTHOUGH NOT NEARLY AS COOL AS TEMPERATURES WILL BE THIS MORNING,
OVERNIGHT LOWS TONIGHT SHOULD FALL INTO THE 40S AGAIN UNDERNEATH
MOSTLY CLEAR SKIES. REPOSEFUL WEATHER WILL ONCE AGAIN CONTINUE ON
MONDAY AS THE UPPER-LEVEL RIDGE AXIS MOVES OVER EASTERN OK AND
SURFACE HIGH PRESSURE BEGINS TO SHIFT EAST OF THE AREA. THIS WILL
CAUSE WINDS TO VEER MORE EAST/EAST-SOUTHEAST, BUT REMAIN LIGHT
THROUGH THE DAYTIME. AFTERNOON HIGH TEMPERATURES ON MONDAY WILL
RISE CLOSER TO SEASONAL AVERAGE, ESPECIALLY FOR SOUTHEAST OK AND
WEST-CENTRAL AR, VARYING FROM THE MID-UPPER 70S AREA-WIDE.
THE PLEASANT WEATHER WILL COME TO AN END BY TUESDAY MORNING AS AN
UPPER-LEVEL LOW SLOWLY MOVES OVER NM AND SOUTHWEST FLOW ALOFT
TAKES SHAPE. AN INFLUX OF LOW-LEVEL WARM AIR AND MOISTURE
ADVECTION WILL OCCUR DURING THE MORNING ON TUESDAY. TRENDS IN
MODELS OVER THE PAST 24 HOURS HAVE SLOWED DOWN THE UPPER-LEVEL
LOW’S FORWARD PROPAGATION A BIT AS MULTIPLE VORT MAXIMUMS ROTATE
AROUND IT. AS SUCH, THE ONSET OF RAIN HAS BEEN DELAYED UNTIL MID-
LATE MORNING TUESDAY. MODELS/ENSEMBLES ARE GOOD AGREEMENT MODERATE
TO HEAVY RAIN WILL DEVELOP EARLY TUESDAY MORNING IN WEST/NORTHWEST
TX IN ASSOCIATION WITH A SUBTLE SHORTWAVE TROUGH AND VORT MAX
AHEAD OF THE MAIN MID/UPPER-LEVEL LOW. THIS MODERATE TO HEAVY
RAINFALL IS FORECAST TO MOVE NORTHEAST INTO THE FORECAST AREA
AROUND MIDDAY AND PERSIST THROUGH THE AFTERNOON/EVENING. AT THIS
TIME, THE HIGHEST RAINFALL AMOUNTS ARE EXPECTED TO REMAIN SOUTH OF
I-40 (ESPECIALLY NEAR THE RED RIVER), WHERE CONSENSUS IN MODEL
DATA SHOW BETWEEN 1 AND 2 INCHES OF RAIN, LOCALLY HIGHER IN SPOTS,
TUESDAY INTO TUESDAY NIGHT. ALTHOUGH THE HIGHEST AMOUNTS ARE
ANTICIPATED TO REMAIN SOUTH OF I-40, MODERATE TO HEAVY RAIN WILL
SPREAD NORTH OF I-40 AS WELL. WITH SOILS STILL SATURATED FROM
RECENT RAINS, A FLOODING RISK MAY DEVELOP FOR PORTIONS OF THE
FORECAST AREA. MORE DETAILS TO COME IN LATER UPDATES.
MODELS SHOW SOMEWHAT OF A REX BLOCKING PATTERN DEVELOPING OVER
THE CENTRAL CONUS BY MIDWEEK, KEEPING THE MID/UPPER-LEVEL LOW
STATIONED OVER THE PLAINS AS IT EVENTUALLY DRIFTS SOUTHEASTWARD BY
THE END OF THE WEEK AND OVER THE NORTHERN GULF COAST BY SATURDAY.
THIS PATTERN WILL KEEP DAILY CHANCES OF SHOWERS AND THUNDERSTORMS
IN THE FORECAST THROUGH AT LEAST FRIDAY BEFORE THE LOW MOVES OUT
OF THE AREA AND RIDGING BUILDS IN. THERE COULD BE ADDITIONAL HEAVY
RAINFALL THROUGH THE WEEK, BUT EXACT DETAIL ARE STILL UNCERTAIN
AT THIS TIME.
AS FAR AS THE SEVERE THUNDERSTORM RISK FOR NEXT WEEK, CHANCES
OVERALL STILL APPEAR LIMITED, BUT ARE NON-ZERO RIGHT NOW. A WARM
FRONT WILL LIFT NORTHWARD FROM CENTRAL/NORTHERN TX TO NEAR THE RED
RIVER DURING THE DAYTIME TUESDAY. A NORTHWARD INCREASE IN
ELEVATED INSTABILITY SHOULD OCCUR TUESDAY AFTERNOON/EVENING,
ESPECIALLY SOUTH OF I-40. SINCE THE INSTABILITY WILL BE
ELEVATED, TORNADOES ARE NOT EXPECTED. HOWEVER, WITH SUFFICIENT
ELEVATED INSTABILITY, LIFT, AND 0-6 KM SHEAR IN PLACE, STRONG TO
MARGINALLY SEVERE STORMS MAY FORM ALONG THE WARM FRONT NEAR THE
RED RIVER. MODELS SHOW ANOTHER UPTICK OF INSTABILITY WEDNESDAY
AFTERNOON SOUTH OF I-40, WHICH MAY BRING ANOTHER WINDOW OF STRONG
TO MARGINALLY SEVERE STORMS. DETAILS TO BE IRONED OUT LATER.
