Amazing temperature swings occur as arctic front moves south

25 WEATHER — The arctic cold front that we've been discussing at length for a while is on its way.

Over the past couple days, brutally cold air has been bottling up in Canada and the northern Plains.

Wednesday morning, that air mass finally started to move, bringing about radical temperature changes for anyone in the way. Things got started early this morning for parts of Montana, where shifts of over two-dozen degrees happened in a matter of minutes.

In addition to the rapid temperature drop, Dillon, MT had to deal with winds gusting over 40 mph as the light snow turned to heavy snow.

As the front continued to plow south over the course of the day, more temperature extremes were observed. Take a look at Cheyenne, WY.

What's really impressive about those stats is that Cheyenne's record of a one-hour temperature drop was easily broken in just 30 minutes. At 4 p.m. Mountain Time, Cheyenne had dropped to -6° with a wind chill of -31°.

When the front arrives in Central Texas tomorrow morning, we will also experience large temperature swings, though not quite as dramatic as places in Wyoming and Montana. Temperatures mid-morning Thursday will be in the mid-40s, but once 1 p.m. rolls around, we could be looking at temperatures in the mid to upper-20s.

Windy conditions are certain, but we will not be receiving any snow outside of a flake or two.
