NWS STORM PREDICTION CENTER NORMAN OK
0301 PM CST WED MAR 04 2026
AREAS AFFECTED...PARTS OF NORTH/NORTHEAST TEXAS INTO SOUTHEASTERN
OKLAHOMA
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 042101Z - 050000Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...A FEW SEVERE STORMS ARE POSSIBLE THIS AFTERNOON INTO THE
EVENING, WITH THE PRIMARY CONCERNS BEING DAMAGING GUSTS AND SEVERE
HAIL. A WATCH MAY EVENTUALLY BE NEEDED.
DISCUSSION...THE LATEST VISIBLE SATELLITE IMAGERY SHOWS CONTINUED
DIURNAL HEATING/DESTABILIZATION OF A RELATIVELY MOIST AIR MASS
(MIDDLE/UPPER 60S DEWPOINTS) EXTENDING FROM PARTS OF NORTH/NORTHEAST
TX TOWARD THE RED RIVER. DESPITE WEAK LARGE-SCALE FORCING FOR
ASCENT, CONTINUED EROSION OF INHIBITION AT THE BASE OF THE EML (SEE
LATEST DAL ACARS SOUNDINGS) IS PROMOTING ISOLATED CONVECTIVE
INITIATION WITHIN ZONES OF DIFFERENTIAL HEATING AND LOW-LEVEL
CONFLUENCE. CURRENT THINKING IS THAT THIS TREND WILL CONTINUE
THROUGH THE AFTERNOON, WITH MAINLY ISOLATED STORM COVERAGE. WHILE
MODEST DEEP-LAYER SHEAR (25-30-KT MIDLEVEL FLOW PER FWS VWP) AND THE
WEAK LARGE-SCALE ASCENT MAY LIMIT STORM ORGANIZATION IN THE
NEAR-TERM, THE DESTABILIZING BOUNDARY LAYER AND STEEP MIDLEVEL LAPSE
RATES MAY STILL PROMOTE LOCALLY DAMAGING GUSTS AND SPORADIC SEVERE
HAIL ON AN ISOLATED BASIS THIS AFTERNOON.
WITH TIME, A STRENGTHENING SOUTHERLY LOW-LEVEL JET SHOULD FAVOR
ADDITIONAL STORM DEVELOPMENT AND ORGANIZATION LATER THIS AFTERNOON
INTO THE EVENING, WHEN THE RISK OF DAMAGING WINDS AND SEVERE HAIL
SHOULD INCREASE. A WATCH MAY EVENTUALLY BE NEEDED FOR PARTS OF THE
AREA, THOUGH TIMING IS UNCERTAIN.
