Get Ready For More Big Temperature Yo-Yo's And Weather Whiplash

The weather this month has, and will continue to, remind
you of this as temperatures keep yo-yoing from one
extreme to another. Coming up: Another big thaw,
and then a harsh freeze right after.
This has been a terrible month in Vermont and surrounding regions if you like consistency in your weather.

It's gone from one extreme to another. You remember the record low of 20 below in Burlington, Vermont on January 7, followed by the record high of 61 degrees just five days later, followed by subzero readings again just two days later.

Temperatures and weather conditions have somewhat stabilized for the past few days, but we're in for weather whiplash again.

Here's the deal: That powerful storm in the middle of the nation is sending a warm front our way initially. That means mixed precipitation (read icy roads) overnight tonight and early Tuesday, especially east of the Green Mountains and in New York's St. Lawrence Valley.

Once the warm front is through, it'll be warm and rainy Tuesday, with highs well up into the 40s. The rain - probably more than a half inch of it - and the warmth is still forecast to maybe shift existing ice jams around, or dam up more water behind them, so look for some more local flooding.

This won't be as bad as the January 12-13 episode because it won't be as warm, there's less snow to melt and it won't rain as hard. But it's still something to watch.

Then the cold front comes through Tuesday night and temperatures will crash early Wednesday. Around midnight Tuesday night, it still might be in the 30s in some locations, but by Wednesday afternoon, it'll probably be in the low teens with a subzero wind chill.  It looks like there will be some snow showers around, too, but accumulations won't be all that great.

Thursday stays cold, with morning lows near zero and highs in the teens. Then, the rolling coaster keeps going with temperatures warming back up into the 40s next weekend.

It's exhausting!

It also looks like this yo-yo trend might continue beyond next weekend, too. The odd thing is it's beginning to look like the overall mean temperature for January will come up somewhere fairly close to normal. It's just that almost none of the individual days will be near normal.

By the way, the storm in the middle of the country has, as expected, created its own batch of weather extremes. There were a couple of tornadoes in Texas and Missouri, and blizzard conditions are ongoing in parts of the central and northern Plains. An active weather pattern indeed!
