Our long subfreezing streak ends across most of Minnesota Wednesday.
Temperatures have been below freezing across most of Minnesota for the past week. The last time the mercury cracked the 32-degree mark in the Twin Cities was last Wednesday, Nov. 7. And that's not even close to the record of 66 days, 16 hours in the Twin Cities during the barbaric winter of 1977-78.

40s ahead
Temperatures in the 40s will feel mighty nice this week. I still think the numbers below are conservative for Thanksgiving week. I can see three to six days at or above 40-degrees in the Twin Cities and southern Minnesota over the next 10 days. We'll see.
November out like a lamb?
The upper-air maps overnight still suggest a mild Pacific air flow into late November. As of now I still don't see any big snow events in sight. Stay tuned.
Western smoke to Minnesota?
Most of the smoke from California's wildfires has been pushed westward into the Pacific Ocean this week.
But westerly winds aloft may begin to transport some of that massive plume toward the Upper Midwest over the next several days. Chances are most of the smoke will stay aloft. But the National Oceanic and Atmospheric Administration's High-Resolution Rapid Refresh smoke model brings slight concentrations to near surface level in the Upper Midwest.
