VALID 241630Z - 251200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS/DISCUSSION...
UPPER AIR PATTERN WILL NOT CHANGE MUCH THROUGH THE PERIOD WITH
BLOCKING RIDGE ACROSS THE ROCKIES AND LARGE UPPER LOW MOVING SLOWLY
SE OUT OF THE LOWER GREAT LAKES. VERY COLD AIR ALOFT WITH THIS LOW
AS WELL AS APPROACHING VORT MAX AND PATCHY SUNSHINE MAY ALLOW FOR
ISOLATED LIGHTNING STRIKES TO DEVELOP ACROSS PORTIONS OF THE OH
RIVER VALLEY.

TO THE WEST...A LEAD SHORTWAVE TROUGH MOVING NEWD ACROSS WA AND
OREGON WILL PRODUCE ISOLATED THUNDERSTORMS. INSTABILITY WILL REMAIN
TOO LOW FOR SEVERE PROBABILITIES...ALTHOUGH SMALL/SUB-SEVERE HAIL
CANNOT BE RULED OUT WITH THE STRONGEST STORMS GIVEN VERY COLD AIR
ALOFT. OVERNIGHT...CONVECTIVE ACTIVITY WILL INCREASE OFF THE NRN CA
COAST AS STRONG UPPER LOW AND JET MAX NOSE INTO THE AREA.
