AVIATION

Overnight patchy fog is possible for areas from Billings (KBIL) east into the Dakotas. Localized visibility below a mile and indefinite ceilings down to 200 feet are possible with any fog.

More Pacific moisture will flow over the area as the front side of a strong ridge moves over the area. This warm advection pattern will bring mainly VFR ceilings to the forecast area through Monday night, with periods of light snow showers this morning to the western foothills and rain showers late in the day today through tonight for the rest of the lower elevation locations. Given the light nature of the shower activity and weak forcing utilized vcsh liberally with this TAF package. Western mountains will see periods of obscuration for the next 48 hours as the Pacific moisture moves through producing periods of moderate snowfall for the higher terrain. Winds will begin to increase this afternoon over the western foothills around KLVM, with gusts of 40kts or more expected by late Monday evening. Current snowpack should shield most other areas from gusty winds through Monday night, though LLWS is expected, as ~2kft winds increase to 35 to 50kts out of the west/northwest. Chambers
