ALTHOUGH THIS IS NOT THE ACTUAL SYNOPTIC COLD FRONT...IT WILL BE

06Z TAFS...COLD FRONT CURRENTLY PUSHING NORTHEAST THROUGH THE TAF
SITES LATE THIS EVENING. WINDS BEHIND THE FRONT RAPIDLY INCREASING
WITH GUSTS 35-40KTS ACROSS MUCH OF EAST CENTRAL IL... AS LOW
PRESSURE BEGINS TO DEEPEN ACROSS THE UPPER GREAT LAKES. WINDS WILL

HOURS WITH GUSTS DIMINISHING TO 20-25KTS BY EARLY SUNDAY
AFTERNOON. WINDS FINALLY DIMINISH UNDER 10KTS BY SUNSET SUNDAY
EVENING.

OTHER CONCERN LATE THIS EVENING INTO OVERNIGHT IS LARGE AREA OF
WINTRY PRECIP OVER EASTERN IA INTO FAR NORTHWEST IL. AS COLDER AIR
WRAPS INTO THIS AREA OF PRECIP...IT IS CHANGING OVER TO SNOW WITH
SOME LOCATIONS REPORT VIS UNDER 1SM. THIS ENTIRE AREA WILL SLOWLY

.MARINE...
422 PM CST

21Z SURFACE ANALYSIS SHOWS MAIN LOW NOW 996 MB NORTH OF LAKE
SUPERIOR WITH ELONGATED AREA OF LOW PRESSURE AND ASSOCIATED COLD
FRONT EXTENDING SOUTHWARD TO EASTERN MISSOURI. PRESSURE GRADIENT
PATTERN ALSO DISRUPTED BY LINE OF CONVECTION THAT TRACKED ACROSS
NORTHERN ILLINOIS AND WEAKENED AS IT MOVED INTO LAKE MICHIGAN.
EXPECT GRADIENT TO SOMEWHAT BETTER RE-ESTABLISH ITSELF THIS
EVENING BUT MAY STILL SEE A PERIOD OF LOWER WIND SPEEDS WITH
TROFFINESS MOVING OVERHEAD. ALSO WILL HAVE LACKING ISALLOBARIC
COMPONENT WITH BEST PRESSURE FALLS WELL INTO MICHIGAN.

EXPECT NW FLOW TO INTENSIFY RAPIDLY OVERNIGHT AS LOW PULLS INTO
ONTARIO AND COLD FRONT SWEEPS EAST OF THE LAKE. STRONG COLD AIR
ADVECTION WILL AID MIXING OF HIGHER MOMENTUM AIR DOWN TO THE LAKE
SURFACE HELPING BOOST GALE FORCE WINDS. GRADIENT AND HENCE GALES
TO RELAX LATE IN THE DAY SUNDAY AS LOW MOVES INTO QUEBEC AND RIDGE
OF HIGH PRESSURE BUILDS ACROSS THE OHIO VALLEY.

UPPER FLOW PATTER TRANSITIONS TO A MORE ZONAL FLOW WITH A FAST
MOVING CLIPPER TYPE LOW PRESSURE AREA MOVING ALONG THE U.S.
CANADIAN BORDER REACHING LAKE SUPERIOR MONDAY MORNING. THIS LOW
WILL DRIVE ANOTHER COLD FRONT SOUTH ACROSS THE LAKE MONDAY
AFTERNOON AND EVENING. YET ANOTHER AREA OF LOW PRESSURE WILL THEN
MOVE ACROSS THE GREAT LAKES LATE TUESDAY INTO EARLY WEDNESDAY.
