DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1212 AM CST THU NOV 21 2024
VALID 221200Z - 231200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
A FEW THUNDERSTORMS ARE POSSIBLE ALONG THE PACIFIC NORTHWEST COAST
ON FRIDAY.
..SYNOPSIS
A LARGE, DEEP UPPER LOW WILL EXIST OVER THE NORTHEAST FRIDAY
MORNING, AND WILL GRADUALLY WEAKEN AS IT DRIFTS EAST THROUGH THE
PERIOD. MEANWHILE, AN UPPER RIDGE WILL SLOWLY SHIFT EAST FROM THE
ROCKIES INTO THE PLAINS, WHILE YET ANOTHER TROUGH PUSHES ACROSS THE
PACIFIC NORTHWEST REGION LATE.
SUBSTANTIAL NORTHWEST SURFACE WINDS WILL MAINTAIN RELATIVELY STABLE
CONDITIONS FROM THE PLAINS TO THE EAST COAST, WITH NO INSTABILITY
FORECAST OVER MUCH OF THE CONUS.
THE EXCEPTION WILL BE AGAIN ALONG THE COASTAL COUNTIES OF WA AND OR,
AS STRONG COOLING ALOFT OCCURS. SCATTERED LOW-TOPPED CONVECTION WILL
BE MOST LIKELY OVER THE OCEAN OVERNIGHT. A FEW THUNDERSTORMS MAY
MOVE ONSHORE, BUT AT THIS TIME THE STRONGER SHEAR FARTHER NORTH DOES
NOT APPEAR TO OVERLAP WITH THE MINIMAL INSTABILITY REQUIRED FOR A
SEVERE THREAT.
