January thaw ahead

A milder Pacific air mass eases into Minnesota Wednesday. Highs Wednesday afternoon will reach the 40s in southwest Minnesota and be above freezing across most of our state.

Skies will be mostly cloudy, but if we break into any significant sunshine in the Twin Cities Wednesday afternoon we’ll have no trouble reaching the 40-degree mark.

The mild weather linger into Thursday.

Storm passing south Thursday into Friday

Forecast models favor a significant rain event across Iowa and Wisconsin late Thursday into Friday. It looks cold enough for snow on the northwest edge of the system as it passes over southeastern Minnesota into Friday.

Right now, it appears the snow edge will track just southeast of the Twin Cities but it’s close enough to keep an eye on for any shift north.

The European Centre for Medium-Range Weather Forecasts model shows the latest storm track between noon Thursday and midnight Friday.

We could cobble together a couple of inches of snow by Sunday morning around most of Minnesota as the colder air squeezes out residual moisture.
