Today-Friday: Cold Conditions Continue, Mostly Dry

Northwest flow remains over the Upper Midwest through Friday as the area continues to be under the influence of a longwave trough. A few shortwave troughs move through the area throughout the week, but the better snow chances remain mostly off to our north for the early to mid week and to our south for the latter portion of the week. There is a wave that moves through tonight that will bring up to a 0.5" of snow for locations north of I-94. Temperatures during the week remain well below normal with highs in the single digits and low teens with low temperatures mainly in the single digits below zero.

Saturday-Early Next Week: Seasonable Temperatures

Ensemble cluster analysis favors the ridge to shift east which would allow for more seasonable temperatures in the mid to upper 20s. This shift also means a potential switch to a more active period. GEFS and EPS members show measurable snowfall a few times next week. As we are still a week away from these snow chances, there is still quite a bit of uncertainty regarding storm track and intensity. The more confident part of the forecast the return to near normal or slightly above normal temperatures.

VFR conditions are forecast for this afternoon with MVFR ceilings becoming increasingly likely (40-60% chance) along and behind a frontal boundary that sweeps through this evening. These lower ceilings may last for much of the day on Tuesday. There may be a brief period of LLWS ahead of this front for low- lying locales that manage to decouple this evening, otherwise SW winds increase to 10-15G15-25kts for the afternoon and back to the NW at similar values this evening, with these winds persisting from the NW through the day on Tuesday.
