High pressure has moved into the area, clearing out the clouds that we had earlier this morning, and will give way to abundant sunshine through the afternoon. It will also bring somewhat breezy winds out of the southeast, enough to push our temperatures near average as we top out in the mid 70s. Tonight, however, a mainly clear sky will hang around as our winds start to relax, which will dip our temperatures to the low 40s, with some of our lower elevations potentially dipping near the freezing point. That being said, be cognizant of the temperatures and consider bringing in plants or vegetation that is susceptible to frost.

The great weather will continue for a several day stretch, which just so happens to coincide with the Memorial Day holiday weekend. This means weather will not be a factor in any outdoor plans, other than having the sunglasses and sunscreen nearby! The upper level pattern will feature a building ridge over the region as a cut-off upper low sits over the southeast states. This “ridge over trough” pattern is one that typically leads to very little change and will effectively be a block for any incoming western systems here in the Upper Midwest. The result will be a continuation of sunny skies Friday through the weekend. The airmass will be dry, so we will likely have some cooler nights mixed in with the warmer days. In fact, Friday morning will be a bit chilly, with lows in the lower 40s locally, but towards Central Wisconsin there may be the threat for scattered frost. Otherwise afternoon highs will remain in the 70s for another day or two before warming into the summer-like 80s. Memorial Day looks mostly sunny and very warm, reaching the mid 80s. Low level moisture should start to rise by then, and certainly into the middle of next week with a well established southerly flow. This means in addition to the building heat, humidity may also be on the rise. Our next chances for any rainfall look to hold off until at least next Wednesday, so garden and lawn watering will be needed to keep things green and growing!
