CHEYENNE, Wyo. (Wyoming News Now) - We started off with very warm temperatures across the region thanks to warm and dry air moving in from the south. Unfortunately, conditions are not expected to improve as we have a massive cold front coming through this weekend. There are already a few isolated rain and snow showers out to the north west that will slowly begin building up as we go into tomorrow evening. It is all from a stationary front that is sitting over us right now combined with two low pressure systems.

Tomorrow morning, most the activity is going to stay in the far west but it will quickly build up with severe storm potentials for the north east and South Dakota by the evening time. The low pressure system then pushes out to the north east dumping heavy snow across much of the central and northern areas of the state. this looks to continue throughout the day on Saturday allowing for our snow cast estimates to show about a foot in Gillette and anywhere from 3 to 6 inches throughout the north east. Only the south east is going to be spared by this heavy snowfall. Other models are showing even more significant snowfall potential with Gillette getting over 26 inches in places like Buffalo and Sheridan around a foot. This is why there are currently blizzard warnings in effect for the north east. Wind gusts will calm down going into those overnight hours and pick up once again as the front pushes through tomorrow during the late evening. These gusts will stay very strong throughout the eastern side of the state all day on Saturday getting well over 50 mph.

Until then, temperatures tonight will be right around the 30s and 40s due to the increase in our cloud cover. Tomorrow, before the front comes through, high temperatures across the eastern side wheel range anywhere from the 60s and 70s all the way to the 80s in the south east. The western side of the state will already have significant snowfall by this time resulting in more 40s and 50s for the high temperatures. Northern areas of the state are expected to have very high rain and snow chances for tomorrow, Saturday, and Sunday. Temperatures will drop 30 to 40° for the highs before conditions clear up and warm up going toward next week. Southern areas are not expecting a lot of precipitation chances, but they are still expecting some very strong wind gusts as the system pushes through on top of a drop in temperatures for the weekend.
