00Z TAF Discussion...

VFR conditions will persist across lower elevations through Tuesday. A push of moisture from the south will bring snow to the Beartooth Mountains late tonight into Tuesday, resulting in obscurations of the high terrain. Scattered light rain/snow showers are expected at lower elevations tomorrow.

Strong winds: By mid evening will see southwest winds increase along the western foothills gap wind areas (KLVM/K6S0 30-40kts), becoming strong overnight (50-60kts). Mountain wave activity is expected to develop overnight along the northern and eastern Beartooth foothills and and the eastern foothills of the Pryor and Bighorn mountains including the KSHR vicinity. Occasional S-SW wind gusts 40-50kts are possible from 08-17z. A cold front will bring strong (gusts 35-50kts) NW winds across lower elevations Tuesday afternoon and evening.
