.DISCUSSION...
TAKING A LOOK AT THE NEWEST 00Z NAM DATA THIS EVENING...WE ARE
GETTING MORE CONVINCED OF SEEING SOME MINOR ACCUMULATIONS OF SNOW
LATE TONIGHT AND INTO TOMORROW MORNING...ROUGHLY ALONG AND WEST OF
A LINE FROM DEXTER TO CAPE GIRARDEAU MISSOURI AND FAIRFIELD
ILLINOIS. UPPER LOW IS NOW IN SOUTHERN ARKANSAS AND MODELS HAVE
BEEN SHOWING THIS LOW MOVING TO THE NORTHEAST TOWARD ST. LOUIS BY
12Z FRIDAY. MOISTURE WRAPS AROUND THIS FEATURE AND WILL GIVE THE
AFOREMENTIONED AREA A GOOD CHANCE FOR SNOW...AS MAJOR COLD AIR
ADVECTION TAKES PLACE STARTING LATER TONIGHT AND CONTINUES INTO
TOMORROW MORNING. AT THIS TIME...ACCUMULATIONS LOOK TO BE LIGHT
AND GENERALLY UNDER AN INCH.

&&

.AVIATION...
PRE-FRONTAL RAIN BAND HAS CLEARED THE AREA LEAVING SOME LEFTOVER 
BANDS OF SCATTERED SHOWERS IN ITS WAKE...ALONG AND AHEAD OF THE COLD
FRONT ITSELF WHICH IS JUST ARRIVING AT KCGI/KPAH. VSBYS/CIGS 
OCCASIONALLY DROP TO MVFR IN THE HEAVIEST SHOWERS...OTHERWISE VFR 
UNTIL THE FRONT PASSES. WINDS THEN SHIFT TO SOUTHWEST AND CONTINUE 
STRONG WITH GUSTS OF 25-30KTS THROUGH CHRISTMAS DAY. CIGS WILL 
GRADUALLY TEND TO THICKEN AND LOWER BEHIND THE FRONT TO BORDERLINE 
MVFR/LOW VFR INTO CHRISTMAS MORNING...THEN WILL TEND TOWARD LOW VFR 
DURING THE AFTERNOON BEFORE CLEARING. A PERIOD OF LIGHT SNOW WILL BE 
ANOTHER ISSUE CHRISTMAS MORNING BUT MAINLY NORTHWEST...EXPECT ONLY
