AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
550 AM EDT TUE APR 26 2011
.DISCUSSION...
RAIN IS BEGINNING TO STREAM NORTHWARD TOWARDS THE CWA. ALONG WITH
BREEZY CONDITIONS THAT WILL CONTINUE THROUGH THIS EVENING. THE SFC
LOW CURRENTLY DEEPENING OVER E MO AND W IL WILL MOVE TO LOWER WI BY
18Z TODAY...AS THE 500MB TROUGH WRAPS UP OVER NE IA. LOOK FOR 850MB
WINDS TO QUICKEN FROM THE CURRENT VALUES AROUND 20 TO 30KTS OUT OF
THE ESE...TO E AT 45 TO 65KTS ACROSS THE ENTIRE CWA. THE RIBBON ON
STRONGER WINDS WILL BE JUST SW OF THE AREA AT 12Z...AND SLOWLY
PROGRESS NORTHWARD TO LAKE SUPERIOR AND THE SOUTHERN LAKE SUPERIOR
SHORELINES BY 00Z WEDNESDAY...WITH ONLY ABOUT A 175 MILE NORTHERLY
MOVEMENT TO THE SFC LOW DURING THE DAYLIGHT HOURS TODAY /FROM
NORTHERN IL TO CENTRAL WI/.
EXPECT THE SFC LOW TO FILL TONIGHT ACROSS NORTHERN WI AND INTERIOR
WESTERN PORTIONS OF UPPER MI...IN RESPONSE TO THE NEXT 500MB LOW
DIGGING INTO THE CENTRAL PLAINS AND A SECONDARY SFC LOW NEARING FROM
THE SOUTHWEST. THIS SHOULD BRING THE NEARLY OCCLUDED WARM FRONT
ACROSS THE EAST HALF OF UPPER MI TUESDAY NIGHT INTO WEDNESDAY
MORNING. AS A RESULT...HAVE KEPT WITH THE THEME OF A NON DIURNAL
TEMPERATURE TREND EAST WITH SLIGHTLY RISING TEMPS OVERNIGHT.
ALSO...EXPECT A BRIEF PERIOD OF LITTLE PRECIPITATION SOUTH CENTRAL
FROM LATE TONIGHT THROUGH THE DAY WEDNESDAY.
AS HAS BEEN THE CASE FOR THE LAST SEVERAL DAY REGARDING THIS
SYSTEM...PRECIPITATION TYPE REMAINS AN ISSUE. COLD ENOUGH
TEMPERATURES WILL SNEAK IN FROM TIME TO TIME ACROSS THE WESTERN
THIRD OF THE CWA TO MIX IN HEAVY WET SNOW. THE HIGHEST AMOUNTS CAN
BE FIGURED NEAR IWD...AS THE COLD AIR LINES UP WITH NE WINDS OFF
LAKE SUPERIOR TO ENHANCE PRECIP AMOUNTS. KEPT THE MENTION OF
ACCUMULATING SNOW ACROSS THE HIGHER TERRAIN NEAR LAKE SUPERIOR FROM
LATE AFTERNOON THROUGH THE OVERNIGHT HOURS...AND AGAIN WEDNESDAY
NIGHT INTO MID AFTERNOON THURSDAY. SEVERAL CHANGES ARE POSSIBLE WITH
THIS FORECAST PRECIPITATION WISE...BUT THE LAST SEVERAL MODEL RUNS
WOULD KEEP SNOW OVER THE WEST HALF OF UPPER MI ONLY. THIS WOULD
BRING THE BEST CHANCE OF SNOW OVER THE HIGHER TERRAIN OF N CENTRAL
UPPER MI /FROM THE HURON MOUNTAINS THROUGH ISHPEMING AND NEGAUNEE/
FROM LATE WEDNESDAY NIGHT THROUGH THE DAY THURSDAY ON NNW WINDS AS
THE SFC LOW EXITS INTO SE ONTARIO AND QUEBEC. THIS TOO IS SUBJECT TO
CHANGE...AS THE GFS INDICATES COOLER AIR WRAPPING IN WITH 850MB
TEMPS FALLING TO AROUND -3C BY 18Z THURSDAY. THE 26/00Z ECMWF ON THE
OTHER HAND DOES NOT COOL MUCH AT ALL...WITH 850MB TEMPS AROUND 2C
/ABOUT 3C WARMER THAN ITS 25/12Z RUN/.
FEW CHANGES WERE MADE BEYOND THURSDAY.

.AVIATION /FOR THE 06Z TAF ISSUANCE/...
EXPECT CONDITIONS TO STAY VFR TONIGHT AT BOTH SITES...HOWEVER MVFR
CONDITIONS WILL SPREAD INTO KSAW/KCMX LATE TUESDAY MORNING INTO
EARLY AFTN ALONG WITH RAIN. EXPECT WINDY AND WET CONDITIONS TO
PERSIST THROUGH TUESDAY EVENING. CONDITIONS SHOULD DETERIORATE TO
LIFR PRETTY QUICKLY ON TUESDAY AFTN ONCE RAIN DEVELOPS AT BOTH SITES.
&&
.MARINE /FOR THE 4 AM LAKE SUPERIOR ISSUANCE/...
LOW PRESSURE OVER SOUTHEAST IOWA WILL MOVE INTO WISCONSIN TODAY
WHILE DEEPENING. EXPECT NORTHEAST WINDS TO INCREASE TO GALE FORCE ON
TUESDAY BEFORE THE DIMINISHING TUESDAY NIGHT OVER THE EAST AND
WEDNESDAY MORNING OVER THE WEST. ANOTHER LOW WILL THEN TRACK THROUGH
THE CENTRAL LAKES ON WEDNESDAY NIGHT INTO THURSDAY AND INTO QUEBEC
BY THURSDAY NIGHT RESULTING IN NORTH TO NORTHWEST WINDS TO 30 KT.
A PERIOD OF GALS MAY ALSO BE POSSIBLE OVER SOUTH CENTRAL LAKE
SUPERIOR THURSDAY. QUIETER CONDITIONS EXPECTED BY THE WEEKEND.
