NWS STORM PREDICTION CENTER NORMAN OK
1235 AM CST SUN DEC 21 2025
VALID 221200Z - 231200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORMS ARE NOT FORECAST ON MONDAY.
..SYNOPSIS
MODEL GUIDANCE CONTINUES TO SHOW AN UPPER-LEVEL RIDGE AND QUIESCENT
CONDITIONS INFLUENCING WEATHER ACROSS MUCH OF LOWER 48 STATES ON
MONDAY. A MID-LEVEL SHORTWAVE TROUGH WILL MOVE FROM THE EASTERN
PACIFIC INTO WA AND BRITISH COLUMBIA DURING THE PERIOD.
INCREASINGLY COOL MID-LEVEL TEMPERATURES WILL SUPPORT POCKETS OF
SCANT INSTABILITY NEAR THE PACIFIC NORTHWEST COAST. WIDELY
SCATTERED SHOWERS AND PERHAPS A FEW LOW-TOPPED THUNDERSTORMS MAY
DEVELOP ALONG THE IMMEDIATE COAST. FARTHER SOUTHEAST ALONG THE
LOWER COAST OF TX WITHIN A SEASONABLY MOIST AIRMASS, WEAK CONVECTION
MAY DEVELOP BUT NEGLIGIBLE FORCING WILL LIKELY LIMIT CONVECTIVE
POTENTIAL WITH THIS ACTIVITY.
