The National Weather Service in Cheyenne says the I-80 Summit could see 6 to 9 inches of snow, good news considering the current fire danger, but bad news for travelers.
Interstate 80 between Cheyenne and Laramie is now open to all traffic in both directions, but Interstate 25 between Cheyenne and Wheatland remains closed.
Parts of extreme southeast Wyoming could see heavy snow this evening through Wednesday, and the Wyoming Department of Transportation is reminding drivers, "Don't Crowd the Plow!"
