Enjoy the warmth through the middle of the week, as a blast of cold air will start to move in just in time for Christmas. Yes, we'll "welcome" highs in the single digits back to the region next weekend. This cold blast will also come with snow Wednesday-Thursday. Click for more information! - D.J. Kayser
I couldn't help but notice how bad the roads were last night with a lousy half inch of snow (on top of glaze ice in some areas). Travel conditions improve today with relative warmth through the middle of the week. The arrival of a real cold front could still set off a few inches by Thursday. A week from Saturday there will be no doubt in your mind that it's late December.
Yes, these are the "good 'ol days", at least in terms of tolerable temperatures. Highs reach the 30s from this weekend into Wednesday of next week, followed by a pre-Christmas temperature tumble. Nothing shriek-worthy, but within 7 days there will be NO doubt in your mind that winter is not to be trifled within across the Upper Midwest.
At this point the Twin Cities metro is running an 11 inch snowfall deficit, to date. And I don't see a major shift in the pattern anytime soon, at least through the end of December - no big snow events as long as prevailing jet stream winds are howling from the northwest. Temperatures run 5-10F warmer than average into Thursday of next week, then a numbing smack just in time for Christmas.
Tuesday was colder than average, but the latest in a series of clippers pulls slightly milder air into town today, a mix of very light snow or freezing drizzle possible - and a few roads may ice up. Relatively mild weather spills over into the first half of next week. And then a punch of Canadian air arrives - just in time for Christmas. Still no big storms of any flavor in sight.
