Don Day Wyoming Weather Forecast: Sunday, March 19, 2023

NOTE: Don Day’s video will return on Monday.

It’s Sunday, March 19 – and while Monday marks the official first day of Spring, it certainly won’t look or feel like it! After a quiet weekend, another weather system will bring mountain snow and valley rain/snow to the west beginning Monday. Highs today will be in the middle 20s and 30s for most, with areas such as the Bighorn Basin, Johnson County, and Natrona County seeing 40s – some places might even see temps in the 50s. A few clouds will pass over throughout the day, but otherwise it will be a mostly sunny day. Winds will pick up in that “Central Wind Corridor” of South Pass through Natrona County; gusts up to about 30 mph are generally expected. Clouds will begin to increase from the west during the later afternoon as that next weather system makes its way to Wyoming.
