DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1104 AM CST SAT DEC 20 2025
VALID 211200Z - 221200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORMS ARE NOT EXPECTED SUNDAY.
..SYNOPSIS
ZONAL FLOW ALOFT WILL BECOME MODESTLY MORE AMPLIFIED ON SUNDAY.
UPPER-LEVEL RIDGING WILL BECOME MORE PROMINENT IN THE CENTRAL U.S. A
LOW-AMPLITUDE SHORTWAVE TROUGH WILL MOVE INTO THE NORTHWEST DURING
THE EVENING. ISOLATED LOW-TOPPED THUNDERSTORMS MAY IMPACT COASTAL
AREAS OF WASHINGTON AND FAR NORTHWEST OREGON. ALONG THE CENTRAL GULF
COAST, A COLD FRONT WILL SLOW AND BECOME NEARLY STATIONARY INLAND. A
WEAK WARM/MOIST ADVECTION REGIME COULD LEAD TO DEVELOPMENT OF
SHOWERS. GIVEN THE SLIGHT RISE IN MID-LEVEL HEIGHTS, RESIDUAL
CAPPING, AND LACK OF GREATER LOW-LEVEL FORCING, POTENTIAL FOR
THUNDERSTORM DEVELOPMENT WITHIN THIS REGIME STILL APPEARS LOW.
