A Winter Weather Advisory is in effect for much of the viewing area.
Today: One batch of freezing drizzle has already made its way through this morning, making some untreated roads, bridges, and sidewalks slick. The next round of a wintry mix is pushing in and will overspread the area through the afternoon as temperatures climb to the middle 30s. Winds will pick up from the west northwest through the day, sustained around 10-20 mph with gusts of 30+ mph. As temperatures cool in the afternoon/evening, we expect a transition over to snow, some of which may be moderate to heavy. Expect a potentially slick evening commute. Winds will reduce visibility and blow snow around.
Tonight: Temperatures will eventually cool to the upper 20s and low 30s tonight as this bizarre system takes a very unusual track. It is expected to halt itself in northeast Iowa, do a loop-de-loop to the west and then continue its track south/southeast through tomorrow. This will keep snow chances in the forecast tonight, especially west and north with the snow heavy at times. As the system is overhead, winds are actually expected to decrease a touch. They will be variable at 5 to 15 mph.
Friday: As the system starts to gain more momentum, we will see snow continuing, especially in the west. In the dry slot to the east, it is not out of the question that we see smaller-scale bands of snow squalls that will produce heavy snow. The best chance for this is in the northeast. Winds will strengthen from the north at 10 to 20 mph, gusting to 30 mph. This will again blow snow and reduce visibility. Snow will begin to taper off through the evening and overnight hours. Expected accumulations of 2-5”, with locally heavier amounts likely in the north and west. Expect hazardous travel throughout much of Thursday night and Friday.
Weekend: Skies remain cloudy Saturday with a fairly breezy northwest wind. Highs will be in the upper 20s/low 30s with lows in the 20s. There will be a chance for light snow on Saturday night/Sunday with highs in the mid 20s and lows in the teens.
Next Week: Skies clear out partially for Sunday night as we dip to the low teens. Another chance for light snow arrives M.L.K Day into Monday night with highs in the upper 20s. Tuesday through Thursday will feature partly to mostly cloudy skies with highs in the 20s/30s and lows in the teens. There may be another chance for light snow on Friday with the potential for arctic air moving in behind it.
