A warming trend combined with a wet pattern could result in a progression of snow to freezing rain to plain old rain over the next 24 hours. A warm overrunning band of moisture will fall into cold air pooled into the western valleys, with Wednesday night snow changing into rain during the day Thursday. There is a possibility that the snow could become freezing rain early Thursday morning. Temperatures will warm to the upper 40s Thursday and then to the mid-50s on Friday. Snow levels will begin at valley levels but will rise to about 7,000’ Thursday and will likely climb to about 8,000’ Friday.
Conditions remain mild and unsettled with a chance of rain showers through the weekend and into the first half of the next.
Freezing rain is a very difficult phenomenon to forecast here in western Nevada, and to be honest, I am not sure why, because we should have a perfect setup for it to happen quite a lot. Freezing rain occurs when rain from warmer air aloft falls into sub-freezing air at the ground, causing it to freeze into a dangerous icy layer. Tomorrow I’ll look at why we should see it more than we do.
