SHORT TERM
(TODAY AND TONIGHT)
ISSUED AT 423 AM CDT MON MAY 5 2025
AN ACTIVE 24 HOURS IS EXPECTED FROM TODAY THROUGH TUESDAY
MORNING, WITH SEVERE STORMS AND LOCALLY HEAVY RAINFALL/FLOODING
POSSIBLE.
AN UPPER LEVEL LOW, CURRENTLY CENTERED OVER SOUTHERN AZ, WILL
MOVE NORTHEAST INTO NORTHERN NM BY EARLY TUESDAY MORNING. AN
ATTENDANT SHORTWAVE IS ROTATING AROUND THE SOUTHWESTERN SIDE OF
THIS LOW, AND IS EXPECTED TO MOVE INTO WEST TEXAS LATE TONIGHT. AT
THE SURFACE, DEEPENING SURFACE PRESSURES TO OUR WEST AND
NORTHWEST WITH THE APPROACH OF THE UPPER LEVEL LOW WILL MAINTAIN
SOUTHEASTERLY LOW LEVEL WINDS, AND CONTINUE TO INCREASE MOISTURE
ACROSS THE REGION. BROAD LIFT IN THIS WARM ADVECTION SET-UP WILL
KEEP CLOUD COVER PERSISTENT, AND SCATTERED MAINLY SHOWERS IN THE
FORECAST THROUGH MOST OF TODAY, ALTHOUGH A FEW THUNDERSTORMS ARE
ALSO POSSIBLE. AS THE LOW APPROACHES, INSTABILITY WILL INCREASE
DUE TO COOLING TEMPERATURES ALOFT AND WARMER TEMPERATURES AT THE
SURFACE. WARMING WILL BE TEMPERED BY PERSISTENT CLOUD COVER IN
OUR AREA. TO OUR WEST, MORE BREAKS IN THE CLOUDS ARE EXPECTED,
LEADING TO GREATER INSTABILITY AND A BETTER CHANCE FOR
STRONG/SEVERE THUNDERSTORMS THIS AFTERNOON INTO THE EVENING HOURS,
ALTHOUGH OUR WESTERN COUNTIES COULD STILL BE AFFECTED BY THIS
ACTIVITY, PARTICULARLY WEST OF A STERLING CITY TO OZONA LINE. THE
MAIN CONCERNS WITH THESE STORMS WILL BE LARGE HAIL AND DAMAGING
WIND GUSTS, ALTHOUGH ISOLATED TORNADOES WILL ALSO BE POSSIBLE.
AGAIN, MOST OF THIS ACTIVITY SHOULD REMAIN WEST OF OUR AREA THIS
AFTERNOON.
AS THE UPPER LEVEL SHORTWAVE ON THE SOUTHERN SIDE OF THE PARENT
LOW MOVES INTO THE AREA LATER TONIGHT, ADDITIONAL THUNDERSTORMS
ARE EXPECTED TO DEVELOP WEST OF THE AREA FROM SOUTHEASTERN NM INTO
THE WESTERN PERMIAN BASIN. THESE STORMS WILL LIKELY MERGE INTO A
LINE OR LINE SEGMENTS, AND THEN MOVE THROUGH WEST CENTRAL TEXAS
AFTER MIDNIGHT. THE MAIN CONCERNS WITH THESE STORMS WILL AGAIN BE
LARGE HAIL, AND DAMAGING WIND GUSTS, ALTHOUGH AN ISOLATED TORNADO
CAN'T BE RULED OUT. IN ADDITION, SOME OF THESE STORMS, MAINLY
NORTH OF A SAN ANGELO TO BROWNWOOD LINE WILL CONTAIN HEAVY
RAINFALL, AND SOME AREAS MAY SEE 1 TO 2 INCHES OF RAIN, WITH
ISOLATED HIGHER TOTALS. WITH PORTIONS OF THE BIG COUNTRY HAVING
RECEIVED HEAVY RAINFALL RECENTLY, HAVE ISSUED A FLASH FLOOD WATCH
FOR AREAS NORTH OF INTERSTATE 20. THIS WATCH MAY BE EXTENDED
SOUTHWARD IF SUBSEQUENT MODEL DATA INDICATES THAT HEAVIER RAINFALL
TOTALS MAY EXTEND FARTHER SOUTH ALONG THE I-20 CORRIDOR.
LONG TERM
(TUESDAY NIGHT THROUGH NEXT MONDAY)
ISSUED AT 224 PM CDT MON MAY 5 2025
A QUIETER WEATHER PATTERN WILL DEVELOP BY MID TO LATE WEEK AND
PERSIST INTO THE UPCOMING WEEKEND. THE UPPER LOW WILL MOVE INTO
EASTERN OKLAHOMA AND KANSAS BY LATE WEDNESDAY, WITH A TRAILING
SHORTWAVE EXTENDING BACK INTO NEW MEXICO AND ARIZONA. COULD SEE
SOME SHOWERS AND A FEW THUNDERSTORMS DEVELOP WEDNESDAY EVENING AND
OVERNIGHT AS THIS SHORTWAVE APPROACHES THE AREA. MODELS DIFFER
REGARDING THIS POTENTIAL HOWEVER, SO NBM LOW POPS SEEM REASONABLE
AT THIS TIME. OTHERWISE, DRY CONDITIONS WILL PREVAIL THROUGH THE
EXTENDED PERIOD, WITH COOLER THAN NORMAL TEMPERATURES THROUGH THE
FIRST PART OF THE UPCOMING WEEKEND. TEMPERATURES WILL WARM TO NEAR
NORMAL LATE THIS WEEKEND AND EARLY NEXT WEEK, AS RIDGING ALOFT
DEVELOPS ACROSS THE PLAINS.
