Interesting temperature map

By: botulism , 7:38 AM GMT on February 03, 2011

Check out the temperature map for the continental US. Interesting because a 'pocket' of sub zero temps have become 'trapped' over Colorado. This is fairly unusual, in that the cold temps usually come down in a 'finger', following the so called 'Alberta Clipper' (wiki it for details). The 'finger' then recedes back into Canada. It's not that common for a pocket of sub zero temps to become trapped South of the Canada-US border.

To see the effects of this, check out Havre, Montana, which often is the coldest spot in the continental US. Tuesday night, Havre was basking in the glow of a -34 (F) temperature. Right now (midnight on Wednesday), they're up to 26 degrees F! That's a 60 degree (F) temperature swing in less than 24 hours.

Meanwhile, Dillon, Colorado (in the heart of the ski areas to the West of Denver) is at -21 degrees F.

Kalispell is currently sitting at zero (F), but we're expecting 22 on Thurs., and up to 35 F on Friday (with a chance of rain).

Good find! You're right, that is a very unusual situation. Wonder what conditions combined to create that cut-off deep freeze.
