1237 PM EST TUE DEC 1 2015 COLD FRONT CROSSES TODAY AND TONIGHT. SECONDARY COLD FRONT WEDNESDAY. HIGH PRESSURE BUILDS LATE WEDNESDAY THROUGH WEEKEND. AND JUST AHEAD OF THE COLD FRONT. COLD FRONT IS NOW PUSHING THROUGH INDIANA AND WESTERN KENTUCKY AT THIS HOUR. WITH A WEAK SURFACE WAVE OF LOW PRESSURE HANGING IT UP IN THIS AREA THROUGH THE OVERNIGHT PERIOD.
HIGH CLOUDS ARE STREAMING OVER THE REGION FROM THE SOUTHWEST AHEAD OF A LONGWAVE TROUGH AXIS OVER THE FOUR CORNER REGION PER LATEST WATER VAPOR AND RAP ANALYSIS. SURFACE OBSERVATIONS THIS AFTERNOON PLACE A WEAK COLD FRONT/DRYLINE OVER THE PANHANDLE OF TEXAS CHARACTERIZED WITH LOW TEENS DEWPOINTS TO THE WEST OF THE BOUNDARY AND 30S/40S DEWPOINTS TO THE EAST. THE LOWER LEVELS PER NAM/GFS SOUNDINGS SUGGEST IT WILL QUITE DIFFICULT FOR PRECIPITATION TO REACH THE GROUND. THE CLEARING OVERNIGHT AND THE DRIER AIR MOVING IN WILL ALLOW FOR A COOLER MORNING AND HAVE GONE BELOW SUPERBLEND VALUES THAT ARE MORE IN LINE WITH ENSEMBLE MEANS WHICH LINE UP TOWARDS RAW MAV/MET MOS. HIGHS SHOULD REACH INTO THE LOW TO UPPER 60S.
CLOSED LOW OVER THE MIDWEST WILL BE RESPONSIBLE FOR PUSHING A COLD FRONT ACROSS THE CWA DURING THE SHORT TERM. COLD FRONT/RAIN SHIELD WILL BE SLOW TO MOVE SOUTH OVERNIGHT TONIGHT INTO WEDNESDAY. THIS WILL LIKELY AFFECT THE CENTRAL PORTION OF THE CWA WHERE IT WILL MERGE WITH THE COLD FRONT. ALBEIT COOLER.

MODELS LIFT OR REDEVELOP WARM FRONT TO OUR NORTH LATER TODAY WITH ADVANCING COLD FRONT SLOWING DOWN AS IT APPROACHES THE MOUNTAINS.
With temperatures near or just above freezing, a rain/snow mix should gradually change to snow, but accumulations still expected to be mainly a quarter inch or less with slightly higher totals north of I-74. This system will bringing cooler conditions to the forecast area along with scattered snow showers, especially across the north, which may mix or change to light rain or sprinkles in the south during the afternoon. The precip threat should shift east of the forecast area by late afternoon or early evening as the 500 mb trof axis edges east into Indiana by then. Upper level heights will gradually build across the Midwest by the end of the work week as a trof moves into the western part of the country.
