THE SFC LOW THRU THE MIDWEST TO THE DBQ VCNTY BY 12Z MON. 50 KT LOW-LVL

8H WRMFNT TO BE LOCATED ACROSS CNTRL WI. BASED ON PROJECTED 8H TEMPS...
NRN WI SHOULD REMAIN ALL SNOW WITH A BAND OF MODERATE TO HVY SNOW
OVRNGT. AFTER COLLABORATION WITH SURROUNDING OFFICES...WL ISSUE A WINTER
STORM WATCH GENERALLY ALONG AND NORTH OF LINE FROM MERRILL TO WAUSAUKEE.
AREAS TO THE SOUTH WL SEE A RAIN/SNOW MIX CHG MORE TO RAIN AS WARMER AIR
ARRIVES OVRNGT. WHILE THUNDER NOT OUT OF THE REALM OF POSSIBILITY OVR
SRN SECTIONS OF THE FCST AREA...WL KEEP IT OUT AS BEST INSTABILITY
REMAINS TO OUR SOUTH.

SFC LOW TO TRACK NE INTO LWR MI BY MON AFTERNOON...THUS PCPN EXPECTED TO
BE IN A DIMINISHING MODE. ADDL ACCUMULATIONS ANTICIPATED OVR NRN WI AS
THE DEFORMATION ZN MOVS THRU THAT PART OF THE STATE. WINTER STORM WATCH
TO BE IN EFFECT TIL 18Z MON FOR NRN WI WHERE TOTALS OF 5 TO 8 INCHES ARE

ACROSS THE U.S. WITH ONE SYSTEM TO MOVE ACROSS THE CNTRL PART OF THE
COUNTRY AT MIDWEEK. COOLER WEATHER GETS PULLED INTO THE GREAT LKS BEHIND
THIS SYSTEM WITH MORE POTENTIAL FOR LK EFFECT ACROSS NRN WI FOR THE END
OF NXT WEEK.

INITIAL COOLER AIR WL CONT TO BE PULLED INTO THE RGN ON TUE AND COMBINED
WITH WEAK CYCLONIC FLOW...CANNOT RULE OUT FLURRIES ACROSS MOST OF THE
FCST AREA. EXCEPTION TO BE NRN WI WHERE NW TRAJS WITH 8H TEMPS AROUND
-14C MAY BRING LK EFFECT SNOW SHWRS ACROSS THE MI BORDER. VILAS CNTY THE
MOST SUSCEPTIBLE AND WL RAISE POPS TO 50 PERCENT. HAVE DROPPED MAX TEMPS
A DEG OR TWO BASED ON EXPECTED CLDS AND WEAK CAA. HI PRES PUSHES ACROSS
THE GREAT LKS TUE NGT INTO WED WITH LINGERING SNOW SHWRS OR FLURRIES
PSBL OVR VILAS CNTY UNTIL WNDS BEGIN TO BACK. NXT SYSTEM TO BE ENTERING
THE CNTRL PLAINS BY WED AFTERNOON SO WOULD EXPECT CLDS TO THICKEN LATE
ON WED.

THIS SYSTEM EXPECTED TO MOV ALMOST DUE EAST TOWARD THE OHIO RIVER VALLEY
BY THU BRINGING A SWATH OF PCPN FROM THE GULF COAST TO THE GREAT LKS.
THERE REMAINS QUESTIONS AS TO THE TRACK OF THIS SYSTEM...THUS WL KEEP A
CHC OF SNOW ACROSS THE ENTIRE FCST AREA ALTHO SRN SECTIONS WOULD HAVE
THE BETTER CHC. BRIEF SHOT OF COOL AIR ARRIVES BY THU NGT AS HI PRES
BEGINS TO BUILD SWD FROM CANADA. FAVORABLE TRAJS AND COLD 8H TEMPS
(AROUND -15C) MAY BRING ADDL LK EFFECT SNOW SHWRS OR FLURRIES TO VILAS
CNTY ONCE AGAIN...ALTHO INFLUX OF DRIER AIR FROM THE HI PRES APRS TO
MAKE THIS A MINOR EVENT. THE HI PRES SHIFTS SE TOWARD THE ERN GREAT LKS
