Here we go again - Severe cold coming next week

Mother nature has yet another round of severe cold on tap for next week.

If you saw my v-log from earlier this week, I gave the impression that this type of thing wasn't going to happen. The arctic oscillation is not totally in polar vortex "destroy mode" and the tropical signal is for above average temps. This is suppose to be the warm stretch but models have been showing this severe cold for several days now. I suspected a moderation in temperature forecast but that never came and maybe that returns afterwards, but the cold is coming. There is something called the EPO that seems to be driving it but we can talk about that another time. Let's get to the details.

THE JET STREAM CHANGES QUICKLY

A storm system will move through Sunday & Monday and out ahead of it above average temperatures. Behind it severe cold will be unleashed.

The jet stream pattern through the weekend favors above average temperatures across the region. Early next week a potent arctic trough will drop out of Canada

This correlates to an ugly temperature forecast for the Dakotas, Minnesota, and Wisconsin. Average is 30-40°F this time of year, so that means high temps in the single digits and lows well below average.

Wind Chill's Not Great Either

The exact temp/wind chill minimums could get colder/warmer as we get closer, but this is what it looks like for Tuesday night next week. It looks to be one notch colder across Minnesota throughout the period where wind chills could reach -40°F. Yikes.

Temperatures of 30°F below average or greater is typically where records get broken. This upcoming arctic outburst could get there. Temperatures may return to average levels by late next week but it's too early to know for sure. I will cover all this in detail on the Friday morning v-log. The scary thing is; it's not winter yet according to the calendar. We've already seen one or two big time cold outbreaks since October across the region. This leads one to suspect we will see more of this this winter.
