MADISON, Wis. (WMTV) - Nearly 40% of Wisconsin is under drought according to the latest Drought Monitor. The hot & sunny weather has taken its toll on our farmers and gardeners. The pattern shows no signs of breaking, but there will be a few opportunities for much needed rainfall.

An upper-level high-pressure system continues to rotate moisture into the Midwest. Dew points remain high - keeping the humidity in place. Lows will fall into the upper 60s - near 70°F tonight. Sunshine breaks back out again Friday afternoon. A frontal boundary will drop through Minnesota and into Wisconsin late in the afternoon. Scattered showers and a few isolated thunderstorms are expected along this frontal boundary late Friday into early Saturday. The front will be weakening as it makes its way into southern Wisconsin. Expect dissipating showers late in the day with a few isolated claps of thunder.

Models differ on the front’s exit speed. If it stays through Saturday morning, a few showers may reignite on the boundary before it clears Wisconsin. Otherwise, partly cloudy to mostly sunny conditions return Saturday with highs again in the upper 80s - lower 90s. The heat holds through Sunday before an upper-level wave dives south late Sunday night into Monday. Rain chances remain low for south-central Wisconsin, but it bears watching. Widespread rainfall is not expected.

Cooler weather arrives next week with NW winds. Highs will drop into the lower and mid 80s Tuesday/Wednesday.
