The start of our weekend was characterized by overcast skies, areas of drizzle, and a few showers this afternoon as a low pressure system continued to skirt South and East across the Upper Midwest. As a result of the gloomy weather, we had a hard time warming up as temperatures stayed several degrees below average in the upper 50s and lower to mid-60s. Periods of scattered showers are expected tonight under mostly cloudy skies as our storm system moves across the Badger state. Winds will gradually shift to the West-Northwest and begin to increase late as low temperatures only fall to the lower 50s. Heading into tomorrow, some clouds early on will give way to increasing sunshine through the afternoon as low pressure slides out of the Midwest. That said, an upper-level shortwave trough is expected to build Southeast into Wisconsin by tomorrow afternoon, sparking up the possibility for a couple isolated showers and thunder locally. Much of the activity, however, looks to stay North and East of the Chippewa Valley. It will be a windy finish to the weekend as winds ramp up from the Northwest at 15-20 mph with occasional gusts between 35 and 40 mph expected during the second half of the day. Highs tomorrow will push into the mid and upper 60s.

Breezes from the Northwest will persist into the new workweek as we remain sandwiched between low pressure to the East and a high pressure system to the West. Sun will mix with clouds as a cold front slides down from Canada, with a large upper trough also taking hold across the region. A colder air mass will filter into our neck of the woods with temperatures to start the week only reaching the upper 50s and lower 60s. Monday night will bring the potential for some patchy frost as clear skies and very dry dew points allow lows to drop into the mid and upper 30s. By Tuesday, our cold front will be located well to the South while a large high pressure center drops out of Canada. Despite plenty of sunshine throughout the day, temperatures will be limited to the mid-50s with a few Northwesterly breezes sticking around. More of a widespread frost/freeze threat will unfold Tuesday night as light to calm winds mix in with our clear conditions and dry air. These ingredients will allow for a rapid cool down overnight with many areas dropping to the lower 30s. Some of our low-lying areas may dip into the upper 20s, setting them up for a freeze scenario. By Wednesday, the upper trough will be forced into New England as a ridge of high pressure nudges into the region. While we’ll still be in the upper 50s, Southerly flow towards the end of the week and into the start of next weekend will allow a warming trend to commence with highs heading back for the mid and upper 60s to around 70. Sunshine will prevail Thursday and Friday, before a few more clouds return Saturday as our next system approaches from the West. We may see, at least, a few showers out of this, but the latest forecast models diverge on outcomes going into next weekend. For now, we’ll continue to watch things the next few days.
