A few snow and rain showers will slide through portions of Western Wisconsin early tonight as an upper low center slides across, while partial clearing is possible overnight. The added moisture from the fresh snowfall could lead to the development of freezing fog in areas overnight, lingering into early Monday. Though many roads have been cleared of much of today's snowfall, temperatures dropping into the 20's will lead to some slick areas.
Weak ridging will arrive on Monday, while more clouds arrive from the west out ahead of the next advancing front. Clouds should remain rather dominant on Monday, while southerly winds help to draw milder air back into the area. Highs are expected to be in the upper 30's, while some 40's will be possible to the south and west. By late in the day a shower or spotty drizzle is possible, with a better chance for a few showers at night. As colder air begins to arrive overnight this will switch to a little snow before ending. Lows will be in the 20's.
The coldest air of the season to date will then take hold, sticking around through the end of the work week. The main branch of the jet stream will be shifting south, limiting weather systems from impacting our area in the coming days, but we will still have a chance for a little snow. Tuesday will bring variable clouds and sun, with highs in the upper 20's. The mercury should drop just a bit into the afternoon as colder air continues to arrive. A flurry will also be possible.
The middle part of the week should bring the coldest days of this outbreak. Upper level northwest flow will tend to bring plenty of clouds and the chance of a few flurries on Wednesday as well, with highs not much above 20. A weak trough will then arrive on Thursday, bringing a better chance for a few snow showers. Highs will again only be around 20.
Temperatures are expected to slowly climb later in the week as the coldest air begins to slide to our east. An area of high pressure should be in the area on Friday, allowing for a mix of sun and clouds and highs in the low 20's. The most interesting system to watch over the next week or so will be a weak low and front that is expected to be in the area by Saturday. This could bring at least a light accumulation of snow with highs in the mid 20's. Sunday will remain mostly cloudy and still a touch below normal.
