We’ve been able to talk about high pressure and quiet conditions for the last several days, but our luck is going to change as we visit Lake Michigan and Wisconsin’s largest city.
At 452PM, ET, Milwaukee was reporting a temperature of 43 degrees with overcast skies and light rain. The entire state was being smothered by clouds and light rain as an area of low pressure centered near Des Moines was attempting to work it’s way northeast into southern Wisconsin. The system is pulling down quite a bit of cold air on the western flank, and rain is changing to snow in Minnesota and Iowa, though that’s a long way off for Milwaukee. In fact, warm air is still surging north through southern Wisconsin, though that will likely continue to pin the low level moisture over Milwaukee tonight.
The low itself will track from Iowa to Ohio through the day tomorrow, keeping showers in Milwaukee overnight. Rain will begin to mix with snow, finally, in Milwaukee tomorrow afternoon. The upper level trough will be flattening out, and melding into a the exit region of a broader trough over the Rockies. The rain won’t end, but the cool down won’t be as significant in Wisconsin as it will be west of their, and snowfall accumulation is not expected. On the other hand, the flattening of the trough will mean associated moisture will remain stuck in the Great Lakes, and though Wednesday doesn’t appear wet, it will be gray.
