One more day remains in the month of April, and for practically everywhere in Wyoming it will be the warmest day that we have seen through the entire month. April overall has been quite warm; it kicked off with some 70s for multiple days before some cold fronts brought a few waves of snow that cooled things off, reminding Wyomingites of the snowy nature of March and April in the state. With the way temperatures are trending to finish the month, the chances for snow activity going forward remain slim outside of mountainous terrain. Of course, in 2020 there was snow in June, so the possibility of a freak storm within the next few months does remain a possibility, even if it’s tiny.

As for the last two days of April for 2021, there will not be any snow. There will not be any precipitation. High pressure and a ridging pattern are keeping the weather across the state quite pleasant, with high temperatures for today hanging in the upper 60s and lower to mid 70s and for the final day of the month in the upper 70s and lower to mid 80s. Sunshine will dominate the skies all day for today, however despite the warmer conditions tomorrow cloud cover will begin to fill into the northern and central parts of the state during the afternoon and evening hours ahead of the weekend.

The first day of May will begin to bring changes as the ridge breaks down and a trough begins to move in. Temperatures will still be quite warm: for a handful of locations Saturday will be warmer than Friday, and for those it isn’t it will only be a couple of degrees cooler. Cloud cover will be prominent once again, however, sticking around all day for Northern and Central Wyoming and building through the afternoon for the southern part of the state. Afternoon and evening thunderstorms are also going to be possible, especially for the northern and central portions. Chances for rain in these regions drop on Sunday, but ramp up heavily in the southern part of the state, beginning as thunderstorms in the afternoon before shifting to a stratiform rainfall during the overnight hours into Monday. Sunday will begin a bit of a cooling trend as well, as the arrival of the trough will bring a cold front dropping highs into the 60s and upper 50s on Sunday and then into the 40s for most of Wyoming on Monday. That will likely be too cold for much thunderstorm activity as the first work week of the new month kicks off.

All precipitation activity that occurs from Saturday through Monday will be added to what happened on Tuesday when it comes to the drought monitor, so there will likely be more changes in the positive direction when the next monitor is released on May 6th.
