Pathfinder Collaboration Collaboration through NWSchat, between DayWeather, WYDOT and surrounding NWS offices. WYDOT Met Julie (DayWeather): …I’m going to give TMC a message to put up [on DMS signs] when there is space. Thinking…”Blowing Snow Expected Tonight Through Thursday 10 AM”. Do you have a more detailed time-frame suggestion? …conditions on 287 will stay snowy/icy, blowing snow probably not as big a concern as on I-80. NWS Jeff Garmon (Cheyenne, WY): We will likely issue a statement later today for travel conditions late tonight along I-80. Will also hit harder on Facebook/Twitter as we get into late afternoon along I-80 corridor….and point them to the wyoroad.info website
