000 FXUS65 KMSO 042139 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 239 PM MST Thu Mar 4 2021 .DISCUSSION...Temperatures are still anticipated to be quite warm for this time of year for the remainder of today and especially for tomorrow. Many locations will be in the 50s and 60s, with lower elevations in Idaho getting up to 70 degrees, by Friday afternoon. These readings will put some locations near daily records. A weak cold front is still expected to sweep through the Northern Rockies on Saturday. This front will bring cooler temperatures and widespread shower activity. The mountains will pick up a couple inches of new snow, while the valleys will receive a rain or rain/snow mix. These cooler temperatures and shower activity will linger into Sunday. A broad trough of low pressure will set up over the western United States next week. The trough will keep temperatures near to slightly below normal for the Northern Rockies through at least Thursday, while also causing fairly active periods of precipitation. The models are still suggesting that a weak circulation will move through the region Tuesday and Tuesday night potentially bringing a decent amount of snow to the higher terrain south of the I-90 corridor, but confidence is still fairly low on this scenario. && .AVIATION...Pilots should anticipate fair flying conditions over the Northern Rockies for the next 24 hours. The only concern will be pockets of fog developing during the morning hours near lakes and rivers, but at this time fog is not a concern at local terminals. && .MSO WATCHES/WARNINGS/ADVISORIES...
