The large, slow-moving storm system will produce widespreadย rain and mountain snow across the region through Thursday.ย The storm watch is in effect from 6 pm this evening through Thursday. Most of the precipitation today and tonight will spread acrossย Southwest into central Montana as low as 5,500-feet.

Nonetheless, with most backcountry areas open to recreation, snowย accumulations of even a few inches should be consideredย significant for this late in the season.
