Today may be the one day this week in Wyoming in which rain may be seen outside of the northern counties. Clouds are moving in from the southwest thanks to a weak low pressure system, and it’s bringing enough moisture to where a few isolated showers will be possible this afternoon. The highest chances for rain are in the southwestern part of the state, with the showers expected to move east-northeastward in the afternoon/evening hours. The only problem is these showers are expected to shrink and dissipate as they move off to the east, meaning that most of us in Wyoming are not going to see any rain. It would be highly beneficial for a shower or two to rain on the Mullen Fire in the Medicine Bow National Forest to help in the fight against it. Conditions towards the end of the week will be highly favorable for it to grow considerably.

Beyond today the only parts of Wyoming that will see any rain are the far northern counties that border Montana. That being said it won’t be clear skies for the rest of the state all week, so the smoky conditions shouldn’t build back in immediately. The problem is going to be those Wyoming Winds. Come Thursday the southern and central parts of the state will see sustained winds pickup to 15-20 mph with gusts over 30 mph coming from the southwest. These will be seen in places such as Rawlins and Casper. The Mullen Fire is off to the east of Rawlins, and to the east-northeast of that is the Rob Roy Reservoir, which is where a lot of Cheyenne’s water comes from. Breezy conditions from the west-southwest will push the fire closer to the reservoir. On Friday these winds will pickup to over 30 mph in the afternoon hours for Rawlins with gusts over 50 mph. Winds like this will easily push the fire to spread off to the east and the northeast. As of now Cheyenne’s water supply has been deemed safe, but the fire could grow considerably given the dry conditions the state is seeing along with those strong winds to finish off the week. Breezy conditions are expected to continue through the weekend and into next week for the region.
