Area Forecast Discussion
National Weather Service Missoula MT
143 AM MDT Sat Sep 21 2024

.DISCUSSION...High pressure rebuilds this weekend. Cooler
overnight low temperatures have prompted Frost Advisories for the
valleys of west-central and northwest Montana that have not seen
freezing weather so far this year. Protect sensitive vegetation
overnight tonight and Saturday night. Dry northwesterly flow takes
over again on Saturday. Models continue to back away from a system
Sunday night, currently there is less than 15% chance of a few
showers or sprinkles in the mountains.

Temperatures rebound through midweek, with daytime highs reaching
10 to 15 degrees above normal by Wednesday. The next chance for
precipitation will be later next week through the following
weekend, though model guidance is not at all on the same page
regarding timing and intensity.
