This weekend in Southeast Wisconsin promises a warm and humid atmosphere, setting the stage for varied weather conditions. An isolated shower may occur on Saturday evening, but any rainfall is expected to cease after sunset, allowing skies to gradually clear overnight. Temperatures will remain warm and muggy, with lows around 70 degrees. Additionally, with high moisture levels and light winds, areas of fog are likely to develop, some of which may persist into early Sunday morning.
As we look to Sunday afternoon, temperatures will rise significantly, reaching the upper 80s near the lake and low 90s inland. The persistent humidity, with dew points around 70 degrees, will elevate heat indices into the mid and upper 90s, calling for caution outdoors. The UV index is predicted to be very high (9), so anyone planning outdoor activities should be mindful of sun protection. The forecasted air quality is moderate; however, it could dip into the “Unhealthy for Sensitive Groups” category along the lakeshore in the afternoon.
Looking ahead to Monday, a round of storms is anticipated in the morning, followed by a hot and humid afternoon with highs across the region expected to reach the 90s. Should clouds and storms dissipate quickly, heat index values could soar to around 100 degrees.
The weather pattern does not cool much for Tuesday and Wednesday, as additional shower and storm chances emerge. However, a cold front arriving late Tuesday is set to bring some respite from the heat and humidity, leading into a more pleasant Thursday and Friday with lower humidity levels and highs in the 70s.
Overall, while the weekend starts off warm and muggy, relief is on the horizon as cooler temperatures are expected to settle in mid-week. Be sure to stay informed with local weather updates to adjust your plans accordingly.
