Rest of November looking to set up far colder than normal

After tying the record for hottest September in mid-Missouri, we made a complete 180 throughout the month of October.

We've already managed to see our first snowfall, along with temperatures that were some 25-30 degrees below normal for Halloween. Winter-like weather has had its way with mid-Missouri in the past week and it may get worse.

While it's not unusual to be cooling off this time of year, the rate and strength which we have done so has been very anomalous. This pattern will likely continue because of the amount of cold air that's building to our north. Some parts of Canada may see temperatures dip as low as 20 degrees below zero by this weekend.

That type of super-charged cold air will dive south with the arctic jet stream several times over the next 2 weeks, leading to temperatures which could dip into the teens before Thanksgiving.

The Climate Prediction Center is on board with this idea. They are forecasting colder than average temperatures for mid-Missouri over the next 6-10 days, as well as the rest of this month.

Will we see more snow?

Well... that's always a much harder question to answer.

One thing is certain in this type of weather pattern: cold, drier air tends to overpower warm, moist flow from the Pacific Ocean. However, this isn't always the case. If you're able to get a better phase of these two air masses, they can create some of our most robust snow events.

The cold, dry air stream will be very strong this week, limiting moisture for the area. Wednesday night rain may change to snow Thursday morning.
Accumulations aren't expected at this time.

The southern stream (warm and moist air) is forecast to strengthen over the next two weeks. This could help encourage more wintry weather.

So... maybe. We'll of course be tracking it.
