THE MAIN FOCUS IS TURNING TO THE W WHERE WE HAVE ONGOING CONVECTION BEING HELPED OUT BY THE LAKE SUPERIOR LAKE BREEZE. EXPECT THIS AREA THAT HAS BEEN PRODUCING PEA SIZED HAIL TO DIMINISH IN INTENSITY AS IT EXITS THE LAKE BREEZE AREA AND MOVES CLOSER TO UPPER MI. KEPT THE POTENTIAL FOR ISOLATED THUNDERSTORMS ALONG THE WI BORDER THROUGH THE OVERNIGHT HOURS...CLOSER TO THE RIBBON OF INSTABILITY OVER WI. WITH STRONG WAA AND A 40-50KT LLJ TONIGHT...EXPECT TEMPS TO STAY IN THE 40S FOR MOST LOCATIONS. THE FAVORABLE DOWNSLOPE AREAS OVER THE W HALF /EXCLUDING THE KEWEENAW PENINSULA/ ALONG LAKE SUPERIOR MAY STAY IN THE MID 40S. OVER THE E A FEW POCKETS OF UPPER 30S WILL NOT BE OUT OF THE QUESTION...FARTHER AWAY FROM THE NEARING SFC LOW OVER E ND AND FAR W MN...WITH A FEW MORE POCKETS OF CLEARING POSSIBLE. EXPECT LOW RH/STRONG GUSTY WINDS TO DEVELOP THURSDAY AFTERNOON...WITH RH VALUES BOTTOMING OUT 20-25 PERCENT W OF A LINE FROM AROUND BARAGA TO IRON MOUNTAIN.

HOWEVER...WITH ONLY LIMITED MOISTURE AVAILABLE IN A NW FLOW AND FAIRLY WEAK FORCING INDICATED...ANY SNOWFALL AMOUNTS SHOULD AMOUNT FROM A DUSTING TO HALF AN INCH. IF PCPN OCCURS SOUTH CENTRAL IT COULD BRIEFLY MIX WITH RAIN DUE TO EXPECTED WARMER TEMPS THERE...BUT DRYNESS OF AIRMASS AND ASSOC EVAPORATIVE COOLING SHOULD TEND TO KEEP PREDOMINANT PCPN TYPE SNOW. SUN...STILL PLENTY OF MODEL DIFFERENCES AND THUS LOWER FCST CONFIDENCE AS THE PATTERN TRANSITIONS FROM NORTHERN BRANCH DOMINANT TO MORE ZONAL PACIFIC FLOW. THE 00Z/12Z ECMWF RUNS ALLOW ANOTHER STRONGER SHRTWV TO BRING A BATCH OF SNOW INTO THE AREA SUN WHILE THE GFS KEEPS DRY CONDITIONS WITH MID-LEVEL AND SFC RIDGING OVER THE AREA. 12Z CANADIAN RUN OFFERS MORE OF A COMPROMISE BRINGING PCPN INTO MAINLY THE FAR SCNTRL CWA. FOR NOW WL MAINTAIN GOING LOW SLIGHT CHC POPS UNTIL MODELS COME INTO BETTER AGREEMENT. MON-WED...AS A TROUGH DIGS INTO THE WRN CONUS THE RESULTING SW FLOW THROUGH THE PLAINS TOWARD THE GREAT LAKES AND WAA PATTERN COULD BRING ADDITIONAL PCPN TO THE NRN LAKES.
