The first named winter storm of the season is here, and Wyoming is included. Winter Storm Warning "Ajax" could bring heavy snowfall over a short period of time, gusty winds, and low visibility.

Most of the snowfall in southeastern Wyoming is expected Monday night into Tuesday morning. Here's a new release from the National Weather Service:

Winter conditions expected for much of southeast Wyoming this afternoon through Tuesday afternoon.

A strong winter storm will move across the central Rockies and central Great Plains during the next 24 hours. Snow will continue to develop west of the Laramie Range, with snow along and east of the Laramie Range late this afternoon through this evening. The snow may be heavy at times, especially along the Interstate 80 corridor from east of Arlington to Sidney tonight and early Tuesday morning. A strong cold front will surge south across the area this afternoon, with Northerly winds increasing to 25 to 40 mph with gusts to 50 mph tonight and Tuesday morning. The combination of the strong winds and snow will create considerable blowing and drifting, with icy and snow packed roads. Travel will become extremely difficult with near blizzard conditions possible over extreme southeast Wyoming into the southern Nebraska Panhandle.

Winter Storm Warning remains in effect from 5 PM this afternoon to 2 PM MST Tuesday.

  • Timing: snow will continue to increase in coverage and intensity late this afternoon and continue through Tuesday morning. The snow may be heavy at times late tonight.
  • Total snow accumulations, 4 to 7 inches with locally higher amounts.
  • Winds/visibility: North winds increasing to 30 to 40 mph with gusts to 50 mph. Visibilities will be reduced to less than a quarter mile in snow and blowing snow.
  • Impacts: primarily travel. Significantly Reduced visibilities will occur at times, along with icy and snow packed roads. Travel will be extremely difficult, especially along Interstate 80 from Cheyenne to Pine Bluffs.

Avoid travel in the warning area. If you are planning to travel in the warning area, listen to the latest weather forecast and consider traveling at another time or by another route. If you must travel in the warning area, use extreme caution when approaching and driving over railroad crossings, take along a winter survival kit. If you become stranded in a rural area. Stay with your vehicle until help arrives. To keep warm in your vehicle, run your engine 10 minutes each hour, and make sure the exhaust pipe is clear of snow to avoid carbon monoxide poisoning.
