DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0217 AM CDT SAT MAY 23 2026
VALID 251200Z - 261200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SCATTERED THUNDERSTORMS WILL BE POSSIBLE FROM PORTIONS OF THE
SOUTHWEST TO THE CENTRAL/SOUTHERN HIGH PLAINS AND ACROSS THE
SOUTHERN OHIO VALLEY AND THE SOUTHEAST. ADDITIONAL SHOWER AND
THUNDERSTORM ACTIVITY WILL BE POSSIBLE ACROSS THE PACIFIC NORTHWEST.
SEVERE STORMS ARE GENERALLY NOT EXPECTED.
ON D3/MONDAY, GUIDANCE SUGGESTS THAT HEIGHT RISES WILL BEGIN ACROSS
THE CENTRAL US AS A HIGH AMPLITUDE RIDGE BUILDS IN FROM THE WEST. AN
UPPER LEVEL LOW WILL BEGIN TO DEEPEN AND MOVE INLAND ACROSS THE
PACIFIC NORTHWEST THROUGH THE PERIOD. THOUGH INSTABILITY WILL BE
MINIMAL, COOLING TEMPERATURES ALOFT WITH THE UPPER LOW MAY PROMOTE A
FEW THUNDERSTORMS TOWARDS THE END OF THE PERIOD.
SLOW MOISTURE RETURN WILL CONTINUE ACROSS MUCH OF THE PLAINS INTO
THE MIDWEST, WITH AREAS OF WIDELY SCATTERED AREAS OF THUNDERSTORMS
POSSIBLE ACROSS PORTIONS OF THE SOUTHWEST TO THE SOUTHERN/CENTRAL
HIGH PLAINS AND FROM THE SOUTHERN OHIO VALLEY INTO THE SOUTHEAST. A
FEW STRONG TO MARGINALLY SEVERE STORMS WILL BE POSSIBLE FROM THE
PLAINS TO THE SOUTHEAST WHERE BETTER INSTABILITY RESIDES, BUT
GENERALLY WEAK FLOW AND SUBSIDENCE ALOFT WILL KEEP ORGANIZED STORM
POTENTIAL LOW.
