If you have Friday evening plans out on the town, you may encounter some rain or snow, depending on where you're at.
A disturbance in the upper atmosphere will move over the Northern Rockies and will force scattered showers to develop.
Our hi-resolution Tru Vu Forecast model indicates the best timing for these showers will be from 7pm to 3am Saturday.

My main concern for tonight is the potential for any freezing rain over extreme northern Montana.
Surface temperatures will drop below freezing later tonight on the Hi-Line, but temperatures aloft will stay above freezing.
This would allow precipitation to fall as rain, but freeze on contact as it reaches the surface.
Significant icing is very unlikely, but it only takes a minor amount of freezing rain to slicken up roads.
Areas to watch will be along Highway 2 from Havre to Glasgow.
Elsewhere, surface temperatures will stay above freezing, so I'm not worried about icing.
At higher elevations, the precipitation should fall as snow, but I would expect less than an inch of accumulation.
We'll continue monitoring the freezing rain potential and update you as needed.
Over the weekend, an upper level low will slide into the Pacific Northwest.
I expect a cold front to pass through the Treasure State late Saturday into early Sunday.
Scattered snow showers will develop across Montana as the trough of low pressure swings east, but it appears north central Montana will miss out on the accumulating snow with this system.
By Sunday, the main energy associated with the system will dive south, and the mountains of southwest Montana will pick up several inches of snow.
This afternoon's latest Tru Vu Snowfall Forecast shows wimpy amounts of snow across the KRTV viewing area.
