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.
1 to 2 feet of accumulation is possible in the higher elevations of the Snowys and Sierra Madres, while areas near the I-80 Summit could see accumulations over 6 inches.
Wednesday's temperatures were a far cry from last week's deep freeze, with several locations in southeast Wyoming and the Nebraska Panhandle either setting or tying record highs.
Heavy snow combined with gusty winds could make mountain travel extremely difficult or impossible in southeast Wyoming Tuesday morning through Wednesday evening.
