BOZEMAN – Weak High pressure is sitting over Montana Monday afternoon producing a mostly quiet weather pattern.

NEXT WEATHER MAKER
The next storm system to impact Montana will be a slow-moving upper level Low. A cold front will pass through the state Tuesday evening followed by a deep trough into Wednesday and Thursday. Look for increasing valley rain Tuesday into Wednesday with snow likely over most mountain ranges. Colder air will begin to dig back down into Montana Wednesday and rain could change to a heavy wet snow Wednesday evening into Thursday.
Travel impacts are likely for Wednesday and Thursday commutes.
