NWS STORM PREDICTION CENTER NORMAN OK
0158 PM CDT MON MAY 05 2025
AREAS AFFECTED...PORTIONS OF FAR SOUTHEAST NEW MEXICO INTO FAR
WESTERN TEXAS
CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY
VALID 051858Z - 052030Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...THE SEVERE THREAT IS GRADUALLY INCREASING ACROSS SOUTHEAST
NM INTO FAR WESTERN TX. SUPERCELLS SHOULD ORGANIZE OVER THE NEXT FEW
HOURS, ACCOMPANIED BY A SEVERE HAIL/WIND RISK. THE TORNADO RISK WILL
INITIALLY BE LOW, BUT SHOULD INCREASE BY EVENING. A TORNADO WATCH
MAY BE NEEDED IN THE NEXT FEW HOURS TO ADDRESS THE IMPENDING SEVERE
THREAT.
DISCUSSION...CONVECTIVE INITIATION HAS RECENTLY OCCURRED OVER FAR
SOUTHEASTERN NM ALONG A CONFLUENCE BAND AHEAD OF A SURFACE TROUGH,
WITH CU GRADUALLY BECOMING MORE AGITATED FARTHER SOUTH INTO THE
TRANS-PECOS REGION OF SOUTHWESTERN TX. AHEAD OF THE
DEVELOPING/INTENSIFYING STORMS, CONTINUED DIURNAL HEATING BENEATH
STEEPENING MID-LEVEL LAPSE RATES IS SUPPORTING 500-1500 J/KG MLCAPE.
WITH STRONGER 500 MB FLOW ROTATING AROUND A PARENT UPPER LOW AND
OVERSPREADING THE SOUTHERN HIGH PLAINS, EFFECTIVE BULK SHEAR
CONTINUES TO INCREASE (CURRENTLY OVER 45 KTS PER 18Z MESOANALYSIS).
AS SUCH, STORMS THAT MATURE AND BECOME SUSTAINED SHOULD BECOME
SUPERCELLULAR, WITH AN INITIAL SEVERE HAIL/WIND RISK.
THE REGIONAL VADS AND 18Z MESOANALYSIS CURRENTLY DEPICT WEAK TO
MODEST LOW-LEVEL SHEAR, WHICH SHOULD TEMPER THE TORNADO THREAT TO A
DEGREE. HOWEVER, A QUASI-STATIONARY BAROCLINIC BOUNDARY, IDENTIFIED
VIA VISIBLE SATELLITE, RESIDES FROM CHAVES COUNTY, NM TO HOWARD
COUNTY, TX. WHILE THE TORNADO THREAT WILL INCREASE LATER THIS
EVENING WITH THE INTENSIFICATION OF THE LOW-LEVEL JET, LOCALIZED
EARLIER TORNADO POTENTIAL MAY EXIST WITH A SUPERCELL THAT CAN ANCHOR
TO THIS BOUNDARY. GIVEN THE INCREASING SEVERE THREAT, A TORNADO
WATCH MAY BE NEEDED IN THE NEXT FEW HOURS.
