Strong low pressure continues to pass by to the north with a large upper trough over our area tonight. This will keep a hold on our weather through tomorrow before gradually moving away on Wednesday.
The blustery west winds from earlier today have died down, with just a light breeze now, and that will stay through the night. Eau Claire remains on the southern fringe of more extensive cloud cover to the north, where even a few showers can be found. Expect a mostly clear to partly cloudy overnight as temperatures drop down into the seasonable 40's.
The upper trough will slowly move southeast on Tuesday, while a piece of energy swings around the backside and into Western Wisconsin. This will make for a breezy, cool and very fall-like day. Showers are also expected to be more numerous, with the best chances coming in the afternoon. Total rainfall should be on the light side, with up to a few tenths possible in the most persistent showers. Though we will start off with some sun, the developing overcast sky will also keep temperatures in the 50's, so plan on needing that light jacket. Winds won't be as strong, but gusts of 25-30 mph are likely.
Clouds and still a few showers will be around into tomorrow night before slow clearing begins to arrive on Wednesday. As the sunshine begins to return, temperatures will start to warm again, with highs returning to the 60's. The nicest weather of this week however will hold off until Thursday and Friday, when high pressure covers the area. This will bring lighter winds, plenty of sunshine and a warm up. Expect highs in the upper 60's to around 70.
The nice pattern looks to continue right into the weekend. The upper trough that is impacting our area now is expected to become a cut off upper low somewhere over the Eastern U.S., making for more of a blocking pattern further west. This will be what helps to extend our nice weather here in the Upper Midwest for a several day stretch.
