6/3AM: Greetings! Good news and bad news. Snow looks to return to southeast Wyoming where it is really needed to help with fire weather conditions. Bad news, it's going to fall along Interstate 80 from Cheyenne to Laramie where travel impacts could be high. A Winter Storm Watch has been posted for the I-80 Summit between Cheyenne and Laramie on Interstate 80 from 11 AM Thursday through 5PM Friday. The Summit could see 6-9 inches of snow that would really impact roads and travel. Accumulations in the eastern foothills into Cheyenne of 2-4 inches looking likely as well. May need Winter Weather Advisories posted for this area in near term updates. Finally, the Snowy Range looks to get another 6-10 inches, which could hinder snow mobilers and hikers, a Winter Weather Advisory may be needed for this area as well. Biggest impact will be travel over the Summit though. Stay tuned to later updates in the forecast!
