Last week saw Wyoming temperatures climb well above seasonal averages in time for the Easter holiday, encouraging Wyomingites to get outside and make the most of the pleasant heat. This week has been filled with a whole bunch of ups and downs, with a pair of cold fronts dropping temperatures to more of what we would expect during the springtime, with the first one dropping highs from the 70s to the mid 40s and the second one from the 60s to the mid 40s. We will see a repeat of that second front’s temperature drop over the weekend when a third cold front moves through, however the effects of this next one look to be a bit different.

Today began with some scattered snow showers in Central and Southeast Wyoming as well as the Nebraska Panhandle, with a few limited areas seeing some showers heading towards the lunchtime hours. Tomorrow will bring nearly identical conditions to Thursday with highs in the low to mid 60s for most of the state and breezes at 20-25 mph from the west with gusts primarily hanging in the 30-40 mph range. Sunny skies will accompany those conditions before a 3rd cold front arrives tomorrow night. But as mentioned before, there are a few differences.

First off is timing: this next cold front looks to arrive a bit later, with snow entering the northern part of the state near midnight Saturday and not making its way towards Central Wyoming until early Sunday morning. The snow itself also looks to be a bit different; not nearly as widespread and likely not as much either, so drought relief will be more limited than what we saw with this one. The chances for Southeast Wyoming to be hit with this on Sunday morning ahead of the lunchtime hours are slim, however unlikely. Temperatures will be a bit colder as well, with low to mid 40s expected instead of mid to upper 40s. It will, however, once again bring powerful northerly winds to the eastern counties of the state, especially Cheyenne and Laramie in Laramie and Albany Counties. This will begin the pattern shift into next week.

Instead of the temperatures rebounding quickly entering the 2nd full week of April, things will continue to cool down into the heart of the week. The jet stream will be shifting as a large trough looks to take hold of the western US heading into the middle of next week, pulling in arctic air to make things colder and ramping up the threat of not just snow showers, but an actually system that could bring several inches to much of Colorado and Wyoming. At this time there is still much in the air as this is several days out, but as of now it is looking like a decent storm could hit the Cowboy State as early as next Tuesday and hang around through next Thursday.
