Blustery! A few flurries tonight; areas of light snow/rain (patchy ice?) possible Wednesday morning

There is a chance for a little snow, rain or a wintry mix of precipitation across northeast Minnesota and northwest Wisconsin through Wednesday morning as warmer air pushes east into our area while low pressure passes by to our north. We’re not looking at any widespread or significant amounts of precipitation out of this system, but there could be just enough frozen precipitation to produce some slippery road conditions in spots for a time Wednesday morning before temperatures warm above freezing Wednesday afternoon.

18z NAM 3km radar forecast thru 7 PM Wednesday.

Up and down temperatures sums up the rest of this week. After a very cold start to the week, temperatures will moderate on Wednesday, but will cool down again on Thursday before we see another brief warmup on Saturday which will be followed by another brief cool down for Sunday. Note: There is a chance we could see a longer stretch of milder temperatures next week with 3-4 days in a row having highs of 50 degrees or warmer, but that’s still a ways off and could certainly change in the next few days.

Keep in mind that our normal highs in late October are in the mid to upper 40s, so although temperatures will be milder on Wednesday, they will still be a little below normal for this time of the year, but certainly closer to normal compared to where they have been over the past week or so.

Here is the high temperature forecast for northeast Minnesota and northwest Wisconsin over the next few days.

Wednesday (October 28th) Mid 30s to Mid 40s.

Thursday (October 29th) Mainly in the 30s.

Friday (October 30th) 30s to lower 40s.

Widespread 40s and 50s this afternoon from Montana to North Dakota, north to Saskatchewan and Alberta, this air mass will move over the Northland on Wednesday, but I don’t think will see any 50s in our area, but some locations should get into the 40s!

Temperatures are running anywhere from 15 to 30 degrees warmer this afternoon compared to Monday afternoon in the yellow outlined area on map.

We had freezing temps as far south as San Angelo, Texas Tuesday morning, while a record low of 32 degrees was reported at Tucson, Arizona!

What a cold snap for so early in the season.

4 PM NHC Update – Tropical Storm Zeta was located about 450 miles south of the Mouth of the Mississippi River with maximum sustained winds of 65 mph. Zeta is currently moving off to the northwest at 14 mph but is forecast to turn north to even north-northeast later tonight and Wednesday.

Zeta is forecast to become a category 1 hurricane tonight, and a landfall somewhere over southeastern Louisiana is expected by Wednesday evening.

A winter storm across the southern Plains heads east which will help pull Zeta on a more north to north-northeast track over the next 24 hours.

Here’s a water vapor loop from Tuesday, October 27th, 2020.

This is pretty crazy! A rather short distance between where snow and ice is occurring to where hurricane conditions are expected on Wednesday.
