Wednesday: A weak cold front sweeping the region from the west will be competing with stable air in place to our east. As a result, morning showers from the west will fizzle out before making it across the Arrowhead region. The better chance for the unstable air to win out will be by the evening with assistance from daytime heating. Any thunderstorms that pop up should be sporadic and short-lived, but they could gain enough strength to produce hail and a brief bout of heavy rain.
We will see areas of fog again in the morning. This improves throughout the morning, lingering directly over Lake Superior. Mostly cloudy skies continue with the front passing. Temperatures are once again limited near the lake, but 80 degrees should be achievable on the hill in Duluth with mid to upper 80s inland. The heat and humidity will continue throughout the holiday weekend with heat indices easily in the 90s.
Thursday: Partly cloudy with a stray shower possible. High 87. SW wind 2-8 mph.
Friday: Mostly sunny with a slight chance for thunderstorms. High 86. E wind 5-10 mph.
