BOZEMAN – Weak High-pressure will continue to produce a calm weather pattern across Montana. Sinking stable air associated with this ridge will produce patchy valley fog across Montana and locally in SW Montana river valley bottoms could see fog overnight.
A weak and disorganized pacific cold front will pass through the state quickly Friday night into Saturday morning. Ahead of the front temperatures will jump into the 50s Friday and possibly a few lower 60s in wind prone regions.
The front could produce a few rain or snow showers Friday evening into Saturday morning but at this time most forecast models show only an inch or two of snow for most mountain ranges and mixed precipitation for lower valleys.
Temperatures will be slightly cooler behind this front on Saturday but jump back up into the 50s by Sunday.
Next week look for another round of rain changing to snow for lower valleys Tuesday into Wednesday with all snow for nearby mountain ranges. Temperatures will start off slightly above normal Monday but fall below normal by Wednesday. Wintry travel impacts are likely Tuesday into Wednesday of next week.
