DENSE FOG ADVISORY until 9 a.m. Wednesday for Ashland, Iron, Vilas, Oneida, Lincoln, Price, Taylor, Clark, Marathon, Portage, Wood, Jackson, Juneau, Adams, and Waushara Counties. The cloudy pattern continues for a couple of more days at least. We will also see areas of fog Tuesday night. If it gets thick enough it could leave a film of frost or ice on some untreated roads, sidewalks, and parking lots. As such stay alert out there and be careful! Lows should reach the upper 20s with light winds. Any fog will lift Wednesday morning but mostly cloudy skies should persist. It looks a touch warmer with highs close to 40 degrees. The wind will become southeast at 5-10 mph.
A potent low pressure system developing toward Kansas Wednesday will start pumping large amounts of moisture north from the Gulf of Mexico toward Wisconsin. This will bring a drenching rain to our region Wednesday night into Thursday morning. Right now it appears the rain amounts will be up around .75 to 1.0”. Given the frozen ground, this could create rapid runoff causing some lowland flooding and some quick small stream rises. We will keep a close eye on the situation. As the storm center shifts east of us late Thursday morning we will have gusty north to northwest winds kick in. This will usher in colder air such that the rain could mix with or change to snow at least in the northwest half of Wisconsin. It is possible that there will be a few inches of snow accumulation in far northern Wisconsin before it ends. Otherwise temperatures will be in the upper 30s Thursday morning then fall.
Finally some sunshine should return Friday but it will be chilly, and breezy in the morning. Lows will be in the low 20s with highs in the lower 30s.
The weekend looks pretty nice with partly sunny skies along with seasonal conditions. Lows will be in the upper 10s Saturday morning and lower 20s Sunday morning. High temperatures are expected to climb to the upper 30s Saturday and around 40 Sunday.
Even warmer air will push in early next week with partly cloudy skies Monday. Highs could top out in the low to mid 40s. The latest data is projecting another powerful low pressure system to roll into the Midwest next Tuesday and Wednesday. It could deliver a lot of rain and wind as it stands now. But given the time of the year, we can’t rule out that it could mix with snow or sleet at times or even switch over to all snow at some point. Be sure to check in for updates.
Have a good evening! Meteorologist Tony Schumacher, 7:15 p.m., 19-November 2019
