DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1110 AM CST FRI DEC 20 2024
VALID 211200Z - 221200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORMS ARE NOT EXPECTED ON SATURDAY.
..SYNOPSIS
AN UPPER-LEVEL RIDGE CENTERED NEAR THE CONTINENTAL DIVIDE WILL
TRANSLATE SLOWLY EASTWARD THROUGH THE DAY AS A STRONG, COMPACT,
NEGATIVELY-TILTED MID-LEVEL TROUGH MOVES INTO THE PACIFIC NORTHWEST.
ACROSS THE EASTERN CONUS A TROUGH WILL PERSIST ON SATURDAY WITH DRY,
OFFSHORE FLOW AT THE SURFACE. THE LACK OF LOW-LEVEL MOISTURE WILL
LIMIT ANY THUNDERSTORM POTENTIAL ACROSS MOST OF THE CONUS. THE ONLY
EXCEPTION WILL BE ACROSS THE OREGON/NORTHERN CALIFORNIA COASTS WHERE
COOLING MID-LEVEL TEMPS OVER THE RELATIVELY WARMER OCEAN WATERS MAY
RESULT IN SOME SHALLOW INSTABILITY AND THE POTENTIAL FOR A FEW
THUNDERSTORMS. THE STRONG LOW-LEVEL JET (50 TO 70 KNOTS FROM 12Z TO
18Z SATURDAY ALONG THE OREGON/NORTHERN CA COAST) MAY RESULT IN SOME
GUSTY WINDS, EVEN WHERE LIGHTNING IS NOT PRESENT. HOWEVER, OVERALL,
LIMITED INSTABILITY SHOULD MITIGATE ANY SEVERE WEATHER POTENTIAL.
