We may be done with the real cold stuff, but models are not very pretty for the lakes region the rest of the month. We get a warm day Wednesday, with a high in the 70s, and Thursday should be solid, but then it kinda turns kinda lousy again. The GFS and Euro both show a similar pattern... general wnw/nw flow, with disturbances riding southeast like clippers and then amping up as they turn east into the Ohio Valley.
Farther into the lakes, like Michigan, you don't even get the brief midweek warmth. The Euro has you in 40s and 50s for the next ten days. Yuck.
