25. 26. Cold last night, one more to go. 27. 28.

The first of two arctic nights brought temperatures to the minus 20s across the region.

I plotted this morning's low temperatures on my map (
to the right). The Keweenaw and the Bayfield Peninsula's remained the warmest from Lake Superior's influence. A reporting station on Oak Island had only -1, Bayfield, Port Wing, and I all measured -2. The areas around Houghton and Silver City (both in the UP) were actually above zero, while only several miles inland the temperature plummeted down to -18.

Clear and sunny across the region.

Clouds were streaming off Lake Superior this morning as the cold air draws warmth and moisture from the above-freezing water. Even a band of low convective clouds have formed in the middle of Lake Michigan. The head of Lake Superior, the bay of Green Bay and the Straits of Mackinaw are all ice-covered by this photo, as well as Lake Winnebago (in Wisconsin) , Mille Lacs Lake, Leech Lake, and Lake Winnibigoshish (all three in Minnesota). As a side-note, Wisconsin has
14,927 lakes while Minnesota only claims 10,000 (11842 in reality).

A Warm-up Still Forecast.

One more cold night to go before warmer air starts returning to the Western Great Lakes. Still a chance of snow and clouds on Thursday, but probably nothing measurable.

While everyone else was clear and cold, I had snow overnight.

I didn't know that it snowed until this morning, but some light lake-effect moved onshore the Bayfield Peninsula. I measured 1 inch on my snowboard and that melted to 0.04". The current snow depth here is 18.1".
