Transient ridging moving over the Northern Rockies will continue to bring mostly dry and overall quiet conditions through the rest of this weekend. Light and variable winds will allow temperatures to fall cooler tonight.
Increasing surface pressure along the Continental Divide and Central Montana mountains will lead to breezy and gusty winds for areas along the Rocky Mountain Front and MT Hwy 200 corridor for the afternoon and evening hours on Sunday. Up to 40 mph wind gusts are possible. These downsloping winds, and overall increasing winds elsewhere, will help to push high temperatures on Sunday near to slightly above normal. A fast-moving shortwave moving over the Northern Rockies tomorrow night increases chances for isolated showers.
For Monday, a shortwave trough with its associated Pacific cold front is expected to move through, cooling temperatures to near or slightly below normal with more breezy conditions expected. Mostly dry conditions will also be likely. Tuesday through next Saturday, an amplified high-pressure ridge will enter back into the area, increasing southwest flow. This will keep the area dry as temperatures warm to between 10 and 15 degrees above normal by Wednesday with breezy southwest winds. The next chance for a widespread chance of precipitation does not move in until Friday night into Saturday as temperatures approach seasonal averages once again.
