Wed. night: 30% chance of scattered thunderstorms in the evening, otherwise partly cloudy. Low: 63 Wind: NW~5
Thursday: Increasing clouds with a 60% chance of scattered showers and storms late in the day. High: 81 Wind: NW 5-10
It was a day of variety Wednesday as expected. Heavy rain fell in the morning in northern Wisconsin. With the thick clouds lingering there all day, highs were only in the 70s. Meanwhile hot sunshine and humidity pounded central Wisconsin with 90s reported south of Wausau. A cold front sliding through Wisconsin Wednesday evening could generate some scattered thunderstorms but the details are still quite uncertain as of this writing at 3:00 p.m. Any showers that do form would move quickly east out of the region by late evening. Lows will reach the lower to mid 60s. Thursday should start with a bit of sun but then clouds will roll in as a low pressure system and cold front slide in from the northwest. This will likely bring scattered showers and storms late Thursday afternoon and night. Some of them have the potential to produce downpours, hail, and gusty winds. Highs will be in the upper 70s to middle 80s.
The remnants of that system could bring a few showers to the area through midday Friday. Otherwise it looks comfortable Friday with highs in the upper 70s to near 80. Drier air and high pressure will build in for Saturday bringing sunshine and highs in the lower 80s. Humidity will be on the increase Sunday as southerly winds return. This coupled with a weak disturbance nearby could generate a few scattered showers. Right now most of next week looks quite warm and humid. There will also be at least the chance of a few periods of showers and storms from time to time as weak upper level disturbances drift through. While not all areas would get hit at once, there could be enough frequency of the showers, day after day to eventually cover most areas. Lows will be into the 60s with highs in the mid to upper 80s generally.
