Another significant winter storm for Southern Idaho Wednesday into Thursday

By  | 

TWIN FALLS, Idaho (KMVT/KSVT) Numerous Winter Storm Warnings and Winter Weather Advisories are in place for Southern Idaho from Wednesday midday into Thursday evening. Complete details on warnings and advisories here. .

Next winter storm will spread snow and possible wintry mix midday Wednesday into Wednesday evening across Southern Idaho. Should start off as snow but could change and mix over to freezing rain and even rain across the Magic Valley and along the I-84 corridor. Temperatures will be the focus Wednesday afternoon and evening. Temperatures could range from 31 to 36 degrees during the afternoon and this is a challenge for the type of precipitation we will see in the region. This makes for a challenging forecast because if temperatures remain below freezing then we see mostly snow and possible freezing rain, if it rises above freezing then we see a few hours of rain. Eventually all of the wintry mix will change back over to snow Wednesday night into Thursday morning.

Here is the timeline for this winter storm:

Wednesday 11am to Midnight: Start as snow across the I-84 corridor with a possible mix or even change over to freezing rain or to rain at times. Temperatures will be key as they will range from 31 to 36 degrees.

Thursday Midnight to 6 am: Precipitation will change back over to snow and some could be heavy at times, snow amounts will range from 2 to 4 inches in the valleys to 4 to 6 further north from Gooding, Shoshone, Richfield, Fairfield into the Wood River Valley.

Thursday 6 am to 6 pm: Mostly snow with an additional 1 to 4 inches across the region and 3 to 6 inches to the north from Gooding, Shoshone, Richfield, Fairfield into the Wood River Valley.

Official snow amounts can be found in the images at the bottom of this post from Wednesday noon until 6 pm on Thursday. Main impacts will be snow and very difficult and hazardous driving conditions. With the threat of rain and freezing rain it will lead to an icy mixture at times Wednesday evening. Winds are not expected to be high but there could a time with 10 to 20 mph winds out of the east-southeast.
