...HEADLINES UNCHANGED...
WILL KEEP THE WSW UNCHANGED...AS 00Z ETA AND GFS MODEL RUNS ARE VERY
CONSISTENT WITH THEIR PREVIOUS RUNS. ONLY CHANGE WILL BE TO KNOCK
DOWN ACCUMULATIONS A BIT AS CRYSTAL GROWTH IS NOT OPTIMAL ACCORDING
TO MODEL FORECAST SOUNDINGS SHOWING THE LAYER ABOVE MINUS 10C BEING
RATHER DRY AFTER 12Z. THIS WILL MEAN RATHER LIGHT SNOWFALL RATES
AFTER DEEPER MOISTURE AND LIFT MOVE THROUGH EARLY THIS MORNING.
CURRENT RADAR SHOWS LEADING EDGE OF FREEZING RAIN AND RAIN ACROSS
NORTHERN ILLINOIS AND INDIANA PUSHING NORTH. P-TYPE CONCERNS ARE
OFFSET IN THE GRR CWA BY COLD SOUNDINGS ACROSS SOUTHERN CWA AS SEEN
ON LAPS SOUNDINGS. LOW LEVEL DRY WEDGE NEEDS TO BE OVERCOME...AND
EVAPORATIVE COOLING SHOULD BE ENOUGH TO MOVE COLUMN COMPLETELY BELOW
FREEZING. CANT RULE OUT A BRIEF MIX AT THE ONSET OF THE PRECIP
ACROSS THE EXTREME SOUTHERN CWA...BUT DECIDED TO LEAVE OUT OF THE
FORECAST.
CLOUDS AND PRECIP SHOULD MEAN HIGHS A BIT BELOW GUIDANCE.
DEFORMATION AXIS REMAINS IN THE AREA INTO TUE AND WILL KEEP THE
CURRENT POPS AND LIGHT ACCUMS GOING FOR TONIGHT. VERY GRADUAL
IMPROVEMENT ON TUE...WITH SOME CLEARING POSSIBLE TUE NIGHT...WHICH
WOULD MEAN SOME RATHER COLD TEMPS AS SFC RIDGE WILL KEEP THE WINDS
LIGHT AND FRESH SNOW COVER WOULD MEAN GOOD RADIATIONAL COOLING
CONDITIONS. WILL KEEP THE CURRENT MINS THAT UNDERCUT GUIDANCE BY
SEVERAL DEGREES

EXTENDED FORECAST
WE WILL BE WATCHING THE EVOLUTION OF A CUTOFF LOW OVER THE SOUTHEAST
US DURING THE EXTENDED PERIOD. AS THE LOW CONTINUES TO MOVE
SOUTHEAST WE WILL SEE RIDGING MOVE INTO SW LWR BOTH AT THE SFC AND
ALOFT. FCST SOUNDINGS SHOW ABUNDANT DRY AIR THROUGHOUT THE PROFILE.
THUS SUNNY WX ON WED AND THU STILL LOOKS PRETTY GOOD. LOW PRESSURE
OFF THE PACIFIC NORTHWEST COAST WILL BUILD A RIDGE OVER THE CENTRAL
US BY THE WEEKEND. THE GFS SHOWS A WEAK COLD FRONT MOVG THRU THE CWA
ON FRIDAY, BUT THE LACK OF MOISTURE WILL PRECLUDE PCPN. HIGH
PRESSURE BEHIND THE FRONT WILL ALSO MEAN DRY WX ON SATURDAY. THE GFS
SHOWS A LOW DEVELOPING IN THE PLAINS BY SUNDAY AND PROGS A WARM
FRONT INTO THE CWA DURING THE DAY. IT ALSO DEVELOPS PCPN WITH THIS
FRONT...ESPECIALLY OVER THE NORTH. WILL GO WITH INCREASING CLOUDS
FOR NOW AND HOLD OFF ON THE MENTION OF PCPN UNTIL TIMING CAN BE
BETTER RESOLVED.
