DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0226 AM CDT SAT SEP 22 2012

VALID 241200Z - 251200Z

...SYNOPSIS...
AS A SHORT-WAVE TROUGH EMBEDDED WITHIN THE LONGER-WAVELENGTH ERN
NOAM TROUGH MOVES RAPIDLY ACROSS NEW ENGLAND TOWARD THE CANADIAN
MARITIMES...A SECOND SHORT-WAVE FEATURE IS PROGGED TO DIG SSEWD OUT
OF ONTARIO INTO THE UPPER GREAT LAKES REGION LATE. AN ASSOCIATED
COLD FRONT IS FORECAST TO MOVE SWD ACROSS THE N CENTRAL CONUS...BUT
LACK OF MOISTURE/INSTABILITY PRECLUDES APPRECIABLE CONVECTIVE
POTENTIAL IN THIS REGION.

ELSEWHERE...WHILE MEAN LARGE-SCALE RIDGING PREVAILS ACROSS THE WRN
STATES...A SMALL-SCALE LOW/TROUGH SHOULD CONTINUE ITS SEWD
DRIFT...MOVING ACROSS THE GREAT BASIN REGION THIS PERIOD. AS IT
DOES...DIURNALLY-DRIVEN CONVECTION IS AGAIN FORECAST TO DEVELOP
ACROSS MUCH OF THE INTERMOUNTAIN WEST. FINALLY...ELEVATED
CONVECTION MAY DEVELOP ACROSS PARTS OF THE LOWER MO/MID MS VALLEY
REGIONS IN RESPONSE TO INCREASING LOW-LEVEL WARM ADVECTION. IN BOTH
OF THESE AREAS HOWEVER...LIMITED INSTABILITY PRECLUDES APPRECIABLE
SEVERE POTENTIAL.
