..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
ORGANIZED SEVERE THUNDERSTORMS ARE NOT CURRENTLY FORECAST ACROSS THE
CONTIGUOUS UNITED STATES ON TUESDAY OR TUESDAY NIGHT.
..CALIFORNIA
AN UPPER TROUGH OVER THE EASTERN PACIFIC WILL APPROACH THE WEST
COAST ON TUESDAY. A MID-LEVEL SHORTWAVE TROUGH EMBEDDED WITHIN THE
LARGER-SCALE TROUGH WILL LIKELY REACH THE CENTRAL AND NORTHERN CA
COASTAL AREAS LATE TUESDAY NIGHT. A SURFACE LOW WILL DEVELOP AND
MIGRATE NORTHEAST REACHING THE OR-CA BORDER BY EARLY WEDNESDAY
MORNING. FLOW WILL INCREASE DURING THE PERIOD AS A 100-KT 500-MB
JET IMPINGES ON THE CENTRAL COASTAL AREAS OF CA. YET, ONLY SCANT
INSTABILITY IS CURRENTLY PROGGED. THIS MEAGER BUOYANCY WILL
GENERALLY FOCUS NEAR THE COAST BUT SPORADIC POCKETS WILL PROBABLY
DEVELOP FARTHER INLAND OVER THE CENTRAL VALLEYS LATE TUESDAY NIGHT.
LOW-TOPPED CONVECTIVE SHOWERS AND ISOLATED THUNDERSTORMS WILL
GRADUALLY INCREASE IN COVERAGE COINCIDENT WITH INCREASED FORCING FOR
ASCENT AND INSTABILITY. GIVEN THE DEARTH OF BUOYANCY FORECAST, WILL
PRECLUDE THE INTRODUCTION OF LOW-SEVERE PROBABILITIES.
ELSEWHERE, QUIESCENT CONDITIONS WILL PREVAIL ACROSS THE LOWER 48.
