Snow - Weather

We have an active day of weather in store with rain on Thursday morning giving way to a threat for strong thunderstorms on Thursday afternoon. Off-and-on rain showers will continue throughout the morning hours and a rumble of thunder can’t be ruled out this morning either. This is a warm system and snow levels are up well above 10,000 ft. as a result.

Thursday afternoon is when things will get interesting. Rain showers will become less widespread and we should see some occasional breaks in the clouds as temperatures warm up into the 60s, but the thunderstorm threat will also increase by late afternoon and into the evening. The ingredients are coming together to support a threat for strong to possibly even severe thunderstorms across Eastern Idaho and Western Wyoming late on Thursday afternoon.

The development of strong or severe thunderstorms will largely depend on whether or not we see clearing in the cloud cover across Central and Eastern Idaho early this afternoon, which would allow for the atmosphere to destabilize. Teton Valley, Idaho will see the highest threat for severe thunderstorms in our area, but the potential exists in Jackson Hole as well.

The main threats with stronger storms this afternoon and evening will be large hail, strong winds (isolated gusts up to 60 mph possible) and frequent cloud-to-ground lightning. There is even a very minor threat for hail to reach one inch in diameter under the strongest thunderstorms.

On Friday and Saturday, the weather pattern will calm down a bit, though we will see enough lingering moisture to result in a chance of isolated light showers or thunderstorms, mainly during the afternoons. A stronger storm system will then approach late in the weekend with showers and thunderstorms developing on Sunday afternoon, before a cold front arrives late Sunday night with rain and snow showers along with much colder temperatures expected on Monday.
