UPDATE

We have cancelled the Dense Fog Advisory in the east as webcams and surface observations indicate conditions have improved and the risk of visibility under 1/2 mile has diminished considerably. Any lingering fog should dissipate through the morning.

We have also updated forecast highs for today. Remarkedly warm air for this time of year is advecting into portions of northern WY and southern MT with upper 50s reported across southern Powder River and Carter Counties. Sheridan got a boost from downslope mixing winds and peaked at 66 degrees in the overnight hours. BT
