Freezing levels: Freezing levels are currently at 4500’ and are expected to inch up to 5000’ tonight. Snow levels will hopefully stay near 4000’ but could rise as the cool air trapped in the eastern basin erodes.

Winds: Stronger westerly flow will override today bringing with it some gusty conditions. Expect ridge top wind gust to exceed 30mph tonight. Winds should taper as they swing SW again tomorrow.
