For anyone who is ready for a day of sunshine and over all the cloud cover, the wait is almost over. We are seeing the final bit of showers and storms early on this afternoon as the system that has brought us these showers moves too far east to continue to impact Wyoming. A large portion of Wyoming is already seeing the return of the sun; the western half of the state is not seeing very much cloud cover as we move towards the back half of the week. The Eastern half will join them as Wednesday progresses with plenty of sun and a jump in temperatures awaits the state on Thursday.

We have to get through today first. We are seeing scattered snow showers shift into rain showers along the I-80 corridor in the Medicine Bow as temperatures rise. There are some rain showers turning into thunderstorms further north, making their way through Natrona County and further east where warmer temperatures will allow for convection. As a refresher, convection is simply when the ground is heated, resulting in the air above the ground warming and then lifting. This results in instability and allows for the development of thunderstorms provided there is enough moisture. These storms are expected to push out of Wyoming during the late afternoon hours, and only a few showers should linger into the evening.

Locations such as Casper will see the sunshine return during the late afternoon and early evening hours as the system moves further off to the East. Riverton has already seen the clouds clear out; the rain chances there are essentially done until at least Friday if not Saturday. For Cheyenne this likely will not occur until the dinnertime hours of Wednesday, but clear skies are expected across the state overnight. This will result in another cool morning ahead of the warmth and sunshine that Thursday brings, but despite the need for drought relief we could use a day of sunshine once in awhile.

After today’s rain chances the next ones look to occur Friday evening in the form of very isolated rain showers. Temperatures on Friday will top off in the upper 70s and lower 80s for most of Wyoming before things cool back off over the weekend as the jet stream takes another dip over the western US. Temperatures will have dropped over 20 degrees between Friday and Mother’s Day on Sunday, with scattered thunderstorms expected Sunday evening. Outdoor plans for Mom should mainly be during the earlier hours of the day unless you wish to get wet. Once those storms start on Sunday, the rain will not stop in some areas until late Monday/early Tuesday as the storms shift into a stratiform rainfall. Once again the location targeted for the most rain is the southeastern corner of Wyoming, so locations like Cheyenne could see over an inch of rainfall with the next system.
