It looks like a cool-down is in the forecast next week. A cold pool of arctic air is currently sitting over far northern Canada and will begin to sink southward over the next nine days.

On this Unisys Weather North American temperature map I have circled the cold air (currently between 5 and -20 degrees as of this morning) and then drew in some approximate lines of the southward extent of the arctic air through time.

The cold temperatures will be pushing our way quickly, nor will the air be as cold once it reaches Lake Superior. Regardless, the models do show that this will be our first cold blast, signaling that winter is arriving.

Up here in the Northwoods, we usually have our first snowflakes just before Halloween ( October 26th this year ) and some permanent snow by Thanksgiving ( some places have a snowpack started, for some of us, we have plenty of time to wait and see ). It looks like we're off to a normal autumn after a pretty nice summer ( I plan on posting about how our multi-year drought finally broke in an upcoming post ).

Any forecast beyond five days is simply a guess, but I took the daily high and low temperatures forecast for my area from the National Weather Service and plotted the numbers.

To that, I added the extended forecast from a different site that is willing to hazard a guess.

All the computer models and variables will continue to improve as we get closer to next Monday, but after that, it looks like we're in for a cool down.

I'm feeling a little cold just looking at a forecast high temperature of 16 degrees next Thursday morning. Brrrrr.

The National Weather Service Office in Duluth, MN has finally released their final snow total map from the last snowstorm.

It looks like the upper St. Croix and the Bois Brule river valleys received the heaviest amounts. And the high terrain just northwest of Duluth received up to a foot of snow too! Some very impressive totals.

And finally, the last map I uploaded was from a screenshot taken from NOHRSC and show the approximate area covered by snow today.
