DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1122 AM CST FRI DEC 13 2024
VALID 141200Z - 151200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORMS ARE NOT EXPECTED ON SATURDAY.
..CENTRAL/SOUTHERN PLAINS TO THE LOWER OHIO VALLEY
AN UPPER LOW WILL MOVE FROM THE CENTRAL PLAINS TO THE GREAT LAKES ON
SATURDAY. A SURFACE LOW WILL WEAKEN THROUGH THE DAY AS THIS TROUGH
ADVANCES NORTHEAST. A SUSTAINED LOW-LEVEL JET WILL ADVANCE FROM THE
OZARKS TO THE OHIO VALLEY AND PROVIDE AMPLE ASCENT AND ELEVATED
INSTABILITY FOR THUNDERSTORM ACTIVITY THROUGH THE DAY. INSTABILITY
SHOULD REMAIN TOO LIMITED FOR ANY SEVERE WEATHER THREAT FROM THIS
ELEVATED CONVECTION. WEAK SURFACE HEATING ACROSS THE ARKLATEX MAY BE
SUFFICIENT FOR A FEW SURFACE-BASED STORMS. HOWEVER, INSTABILITY WILL
BE WEAK AND ASCENT WILL MOSTLY BE FOCUSED NORTH OF THIS AREA.
THEREFORE, NO SEVERE STORMS ARE ANTICIPATED.
..CALIFORNIA TO THE PACIFIC NORTHWEST
A TROUGH APPROACHING THE PACIFIC COAST ON SATURDAY WILL RESULT IN
SCATTERED THUNDERSTORM ACTIVITY FROM SOUTHWEST WASHINGTON TO CENTRAL
CALIFORNIA AS COOLER AIR ALOFT STEEPENS LAPSE RATES ACROSS THE
REGION. OVERALL, WEAK INSTABILITY COMBINED WITH RELATIVELY WEAK
LOW-LEVEL FLOW SHOULD PRECLUDE ANY SEVERE WEATHER THREAT. A MORE
FOCUSED LOW-LEVEL JET WILL RESULT IN STRONGER LOW-LEVEL FLOW ACROSS
THE CENTRAL CALIFORNIA COAST LATE SATURDAY MORNING INTO THE EARLY
AFTERNOON. HOWEVER, DURING THIS PERIOD, FORECAST SOUNDINGS INDICATE
MINIMAL TO NO INSTABILITY WHICH SHOULD PRECLUDE ANY SEVERE WEATHER
CONCERN.
