DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1250 AM CST FRI DEC 19 2025
VALID 201200Z - 211200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
ISOLATED THUNDERSTORMS WILL BE POSSIBLE ACROSS COASTAL SECTIONS OF
WASHINGTON AND NORTHWEST OREGON SATURDAY NIGHT.
..SYNOPSIS
BROADLY CYCLONIC MID-LEVEL FLOW ASSOCIATED WITH A SHORTWAVE TROUGH
OVER ONTARIO/QUEBEC PROVINCES WILL SHIFT EASTWARD ACROSS THE GREAT
LAKES AND NORTHEAST ON SATURDAY AS AN UPSTREAM TROUGH APPROACHES THE
PACIFIC NORTHWEST SATURDAY NIGHT. SLOWLY RISING HEIGHTS WILL EXTEND
ACROSS THE SOUTHERN U.S. THROUGH SATURDAY NIGHT IN ASSOCIATION WITH
AN UPPER-LEVEL HIGH CENTERED OVER NORTHERN MEXICO.
AS MODEST HEIGHT FALLS DEVELOP ACROSS THE PACIFIC NORTHWEST LATE
SATURDAY, VERY WEAK BUOYANCY (ON THE ORDER OF 100 J/KG) MAY DEVELOP
ALONG THE IMMEDIATE COASTAL AREAS. ISOLATED CONVECTIVE ELEMENTS MAY
DEEPEN SUFFICIENTLY FOR CHARGE SEPARATION/LIGHTNING PRODUCTION.
MODEST LOW-LEVEL MOISTURE SHOULD BEGIN RETURNING TO THE UPPER
TEXAS/LA COAST SATURDAY ON STRENGTHENING SOUTHERLY FLOW, WITH 50S TO
NEAR 60 DEG F SURFACE DEWPOINTS AS FAR NORTH AS THE ARKLATEX REGION.
THE PRESENCE OF A CAPPING INVERSION AND LACK OF NOTABLE ASCENT
SUGGESTS NEGLIGIBLE CHANCES FOR THUNDERSTORMS THROUGH SATURDAY
NIGHT.
