DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1220 AM CDT WED JUL 22 2026
VALID 231200Z - 241200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORM POTENTIAL APPEARS LOW ON THURSDAY. HOWEVER,
LOCALLY GUSTY WINDS COULD OCCUR WITH THUNDERSTORMS ACROSS THE
CENTRAL HIGH PLAINS.
..DISCUSSION
IN THE MEAN, AN AMPLIFIED UPPER RIDGE WILL PERSIST ACROSS HE WEST,
WITH THE SUBTROPICAL HIGH OVER TX SHIFTING WEST TOWARD THE FOUR
CORNERS VICINITY THROUGH THE PERIOD. AN UPPER SHORTWAVE TROUGH
EMBEDDED WITHIN THE EASTERN PERIPHERY OF THE UPPER RIDGE WILL
MIGRATE SOUTHEAST FROM THE CENTRAL ROCKIES TO THE MID/LOWER MO
VALLEY THROUGH EARLY FRIDAY MORNING.
SOUTHERLY LOW-LEVEL FLOW ACROSS THE PLAINS WILL RESULT IN A BELT OF
MODEST BOUNDARY-LAYER MOISTURE ACROSS THE CENTRAL HIGH PLAINS. STEEP
MIDLEVEL LAPSE RATES WILL FOSTER WEAK INSTABILITY ACROSS PARTS OF
WY/CO INTO WESTERN KS. SCATTERED THUNDERSTORMS WILL DEVELOP DURING
THE AFTERNOON AND SPREAD EAST/SOUTHEAST ACROSS THE CENTRAL HIGH
PLAINS. A DEEPLY MIXED BOUNDARY LAYER WILL SUPPORT ISOLATED STRONG
OUTFLOW GUSTS. HOWEVER, WEAK VERTICAL SHEAR AND LIMITED INSTABILITY
WILL PRECLUDE SEVERE PROBABILITIES AT THIS TIME.
