HAD BRIEF SHOT OF --SN HERE AT OFFICE A WHILE AGO...AND GOT A REPORT OF
SLEET IN DEWITT. WSR-88D SHOWS WEAK RETURNS EXTENDING FROM
MAQUOKETA...TO MORRISON AND PRINCETON. THIS IS DEPICTED WELL ON META 285K
ISENTROPIC SFC WHICH SHOWS LIFT EXITING FAR N/E BY 18Z. 
WON/T UPDATE ZONES FOR PCPN DUE TO ISOLATED AND LIGHT NATURE...AND WILL
CONTINUE TO HANDLE IN SHORT TERM FORECASTS (NOWMLI).
MOST AREAS TO SEE AT LEAST SOME SUNSHINE THIS AFTERNOON BASED ON
SATELLITE TRENDS. ANTICIPATE MINOR CHANGES TO TEMPS/WINDS WITH LATE MORNING
ZONE UPDATE.

SYSTEM STILL ON TRACK NEXT 24-36 HRS WITH PCPN DEVELOPING LATER THIS EVENING
AND OVERNIGHT. BASED ON MOISTURE AND STRENGTH OF FORCING 
A WINTER WEATHER ADVISORY IS LOOKING LIKELY FOR TONIGHT/FRI FOR PORTIONS OF THE
AREA. VARIOUS THERMAL PARAMETERS SUGGEST SNOW OR MAINLY SNOW ALONG AND 
NORTH OF I-80...WITH WINTERY MIX IN THE SOUTH. ATTIM IT LOOKS LIKE AMOUNTS 
OF 1-3 INCHES LIKELY WITH HIGHER AMOUNTS POSSIBLE...STILL PERUSING LATEST MODEL
DATA THOUGH.

.DVN...
IA...NONE.
IL...NONE.
MO...NONE.
