Weak high pressure will gradually build in, providing clearing skies from west to east throughout the rest of our Wednesday. Light rain showers will linger into this evening on the east end. Meanwhile, we??ve seen gusty northwest winds pulling cool air off of Lake Superior. High temperatures will only manage upper 40s and low 50s this afternoon.
Tonight will be coolest inland, away from the lakes, especially east where lows dip into the mid 20s. Elsewhere, temperatures should hold into the mid and upper 30s overnight.
After a chilly start, Thursday looks pleasant enough with sunshine in the morning. Highs will be seasonal, in the 50s. It??ll be coolest across western Upper Michigan with highs struggling to break above the 50 mark. The nice weather will be short-lived and cloud cover will increase ahead of the next fast-moving cold front.
The next batch of dreary weather will come Thursday night through Friday morning. Most of the area will see persistent drizzle with highs in the upper 40s during the day. Nighttime temperatures will stay just warm enough to keep widespread mixed precipitation off the grid Friday night.
However, by Saturday, we??ll begin to see lake effect clouds and rain as a stronger disturbance settles into the region. Reinforcing cold air will filter in across the higher terrain of west-central Upper Michigan, bringing a wintry mix of rain/snow pellets into Saturday evening. Overnight lows will fall far enough to allow for the first wet snowflakes to fly across the higher terrain into early Sunday. Warmer temperatures will keep precip as all rain in the lower elevations and by the shore.
Whether this first dose of winter weather will be enough to see our first measurable snowfall remains unclear. Any accumulation in the higher elevations of the western U.P. would melt almost immediately. However, Karl, Dustin and myself are keeping a close eye on the next potential weather maker that could bring more potent cold air and better moisture by Tuesday.
