Temperatures improving slowly

We’re still looking to see sub-zero overnight temperatures for much of the region. The National Weather Service has issued a Wind Chill Warning until 10AM Wednesday. However, we’re slowly starting to see normal temperatures return. We have some cloud cover moving down from the north tonight, leading to mostly cloudy skies and some light snow coverage. Expect sunny and cold weather with highs getting back into the teens and 20’s for Wednesday and Thursday.

Overnight, lows around -9° for Idaho Falls, 1° for Pocatello and 0° for Jackson. Mostly cloudy with a slight chance of snow. North winds around 5-10 mph.

For Wednesday, look for mostly sunny skies and daytime highs peaking around 18°. North winds at 5-10 mph, with wind chill values as low as -20°.

Thursday, mostly sunny, with a high near 23°.

A few snow showers Friday and Sunday as a couple of systems roll in from the Pacific.
