.DISCUSSION...Patchy fog in many area valleys this morning will
dissipate quickly today under mostly clear skies and a building
ridge. Today and tomorrow will both be warm, gorgeous fall days to
Saturday afternoon winds will start to pick up ahead of a cold
front that will move through the region Saturday night and Sunday.
The biggest impact from this system will be winds, with the
strongest winds in northwest Montana. Strong surface winds will be
supported by a strong jet stream and should be fairly consistent
throughout the day. Expect the strongest winds during the day
Sunday. Main impacts expected are downed trees and the associated
road blockages and power outages in northwest Montana. It will
also be a very windy day on Flathead Lake Sunday impacting the
Mack Days fishing tournament.
The region will be under a northwest flow for the first part of
next week, as the weekend system exits the Northern Rockies. Some
models do indicate weak impulses of energy moving through the
apex of a low amplitude ridge building over the area. Confidence
is low at this time for any real measurable precipitation to
fall. Otherwise, slightly above normal high temperatures and cool
nights can be expected through the week next week.
.AVIATION...Areas of patchy fog this morning will clear
out quickly once the sun starts to shine as a ridge continues to
build over the region. Terminals KGPI and KMSO are most likely to
be impacted by fog this morning. Once the fog burns off, no
impacts to aviation are expected today.
