Wednesday: The area of low pressure responsible for yesterday's rain is crawling eastward. We're left with cloudy skies and spotty showers behind it, particularly the Arrowhead region and South Shore. An area of high pressure will gradually work to clear skies from the west, allowing International Falls to be a warm spot reaching near 76, while stubborn cloud cover draped over Northwest Wisconsin keeps temps stuck in the low to mid-60s. A continuing east wind will also limit temperatures along the shoreline, leading to an unseasonably cool day overall. Clear skies Wednesday night will allow temperatures to drop into the mid-40s to low 50s.
Thursday: Sunshine carries through Thursday with mid and upper 70s inland, but a lake breeze once again keeps us cooler near Lake Superior. Thunderstorms will work into the region late Thursday night into Friday morning from the west, but stable air in place will try to break these down.
Friday: Humidity will spike Friday as southerly flow takes over, likely resulting in fog around Lake Superior and limiting temperatures while heat takes over inland with a high near 82. Heat and humidity stay with us through the weekend.
