The Sunshine Train is Coming to a Stop
November 5th, 2020
Since the last snowstorm near the end of October, Wyoming has essentially seen nothing but sunshine as temperatures have climbed to 20+degres above seasonal averages around the state. That two week trend is finally coming to an end as we head into this weekend. High pressure over the rocky mountains has brought lovely fall and now spring-like weather to the Cowboy State, but that high pressure is breaking down as our next system arrives. The clear nights are also coming to an end, and for some locations that begins tonight as clouds begin to creep in from the west during the overnight hours tonight. These clouds will stick with us into Friday as they continue to thicken ahead of the next system, however southerly winds are going to keep the warmer temperatures around into the weekend.
The system coming in looks similar today as it did yesterday, however there are a couple of key differences. For starters, the timing of arrival looks to be delayed, especially in regards to the cold front. So high temperatures on Saturday now are expected to replicate what we have seen all week. In fact, low temperatures Saturday night are only going to be a few degrees colder in some places than they have been all week. Sub-freezing temperatures are not expected to arrive until Sunday night after the storm has passed, and while conditions next week will certainly be cooler than this week, they are not going to be sub-freezing except during the overnight hours.
Precipitation with this storm will likely begin as rain for many across Wyoming, shifting into a wintry mix for most during the early morning hours heading into Sunday. Higher elevations are likely the only ones that actually see some snow. The warmer temperatures we’ve been seeing all week should still prevent most if not all accumulations of snow in most parts of Wyoming. The northwestern part of the state around Jackson and Yellowstone are the areas most likely to see accumulations simply because they’ve been a good bit cooler all week long despite the sunny conditions. Even a place like Laramie likely will not see more than an inch or two of snow accumulation, and two inches would most certainly be a stretch. Places like Cheyenne likely will just get wet with a tease of wintry mix, while a place like Casper might see a little snowfall, but accumulations should still be negligible.
Lastly, Sunday looks to be a very windy day for the middle of the state, with wind speeds in excess of 30 mph sustained and gusts approaching 60+mph from the southwest as the cold front finishes passing through the state. Calmer winds will return Sunday night as they shift to the north on Monday, leading to colder conditions to start the next work week.
