MISSOULA - Light precipitation Tuesday morning will become widespread by late-afternoon.
Temperatures will sit well above average, in the upper 40s for Missoula, and even low 50s or Hamilton as Tuesday is expected to be the warmest day of the week.
Snow chances and accumulation will improve with this system starting late Tuesday night into Wednesday afternoon.
Overnight lows will drop to the upper 20s and low 30s as snow levels will be lowering to the valley floor overnight tonight, but accumulations at these lower elevations will be roughly an inch or less.
Between 3" and 5 " of snow can be expected over the mountain passes by late Wednesday afternoon, with the main areas of concern being Lolo, Lookout and Marias passes.
Another low pressure system will move in on Thursday bringing more rain/snow mix for valley locations and another dusting of snow for mountain passes.
By the end of the workweek we will dry it out with seasonal temperatures for the weekend.
