...DISCUSSION...
SYNOPTIC UPPER TROUGH WILL PERSIST OVER THE ERN U.S. BUT GRADUALLY
SHIFT EWD DURING THE PERIOD. A LARGE AREA OF SFC HIGH PRESSURE OVER
THE SERN STATES WILL BUILD SEWD AND MAINTAIN INFLUX OF DRY CP AIR
OVER THE GULF RESULTING IN STABLE CONDITIONS INLAND.
BAND OF WINTRY PRECIPITATION WILL CONTINUE SEWD THROUGH MN...WRN WI
AND NERN IA EARLY THURSDAY IN ASSOCIATION WITH A PROGRESSIVE VORT
MAX EMBEDDED WITHIN NWLY FLOW ALOFT. STEEP LAPSE RATES AND WEAK
ELEVATED CAPE WILL ACCOMPANY THIS FEATURE...SUGGESTING SOME OF THE

STRIKES CANNOT BE RULED OUT...BUT INSTABILITY IS EXPECTED TO REMAIN
TOO LIMITED TO SUPPORT 10% OR GREATER COVERAGE OF THUNDERSTORMS.
