Some Slight Changes To Our ForecastDecember 9th, 2012 at 12:14 pm by Chad Evans under Chad's WLFI Weather Blog
UP TO 16″ OF SNOW SO FAR WITH BLIZZARD……….
Up to 16″ of snow has fallen in western Minnesota & 3″ in southern Wisconsin. Up to 20″ is possible nearer to Lake Superior in northeast Minnesota. Snow has been reported as far south as the Indiana/Michigan line & far northern Illinois. Conditions will continue to worsen from the Dakotas to central Lower Michigan today-tonight.
HOWLING WINDS & ZERO VISIBILITY………..
Winds have gusted to 46 mph near Minneapolis. At Miller Muni Airport near Huron, South Dakota, temperature is 9 above with sustained winds at 35 mph with gusts to 44 mph! At Marietta, in western Minnesota, temperature is 10 with sustained winds at 39 mph with gusts to 49 mph! Even near Le Mars, Iowa, DOT station had sustained winds at 36 mph at last check with 14 degrees & falling rapidly. Ellen, South Dakota has 2 degrees with SUSTAINED north winds at 39 mph with gusts to 46 mph! Visibility is zero in these areas. Zero visibility will overspread Minnesota to parts of Iowa 7 eventually Wisconsin & then Michigan (though Michigan is not as open as the Plains, but it will still be blinding snowstorm).
SHOWERS HERE (EVEN A T’STORM POSSIBLE!)………….40s DAY (FEW LOW 50S IN THE SOUTHERN COUNTIES)
As for us, showers will continue all day with even an isolated t’storm possible as a tongue of warmer, unstable air is thrust up over the cold, stable surface. This is elevated instability & though it may be marginal, enough may arrive for lightning discharge. This will not be an all-day rain………but SHOWERY, rather. Between showers, however, there will still be drizzle & fog around.
SEVERE THREAT SOUTHERN INDIANA TO TEXAS…………
Severe weather threat will exist from Evansville, Indiana & Louisville, Kentucky to Texas this afternoon & this evening. In fact, temperatures are in the 60s in southern Indiana!
SOME WET SNOW POSSIBLE HERE……….
Interestingly, models bring brief period of wet snow in late tonight as cold air rushes in with nothing more than a dusting on the grass in a few places. THEN, they pivot in a wave of light snow in during the late afternoon & evening less than 1″ of accumulation. So, there are two times for some snow potential, per recent analysis.
