642 FXUS65 KMSO 040824 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 224 AM MDT Tue Jun 4 2024 ...Windy again this Afternoon and Evening... .DISCUSSION...A secondary front with a strong upper level jet max over the region will bring windy conditions with showers and even a thunderstorm (primarily across SW Mt) this afternoon and evening. Winds will be strong enough for choppy conditions on Flathead Lake where a lake wind advisory is in effect. Stronger showers and/or a storm this afternoon will have gusty outflows over 45 mph. Thursday and Friday, the ridge will have warmed things up to about 10 degrees above normal for this time of year. This marks the beginning of our first extended hot spell of the year. Most of the valleys in western Montana will warm into the low 80s, with central Idaho low elevation valleys reaching the low 90s. The hotter than normal weather continues into the weekend. It`s looking like Saturday will be the hottest day of the week. The lower valleys of central Idaho may approach the 100 degree mark with readings in the mid 80s to lower 90s across western Montana. A front will move through the region Sunday and briefly flatten the ridge. The increased instability and moisture will trigger showers and thunderstorms across the entire Northern Rockies. A few showers and thunderstorms will linger across southwest Montana Monday afternoon. Otherwise, ridging will re- establish itself over the NR through at least the middle of next week thus continuing above normal temperatures and mainly dry conditions. && .AVIATION...All terminals will experience gusty westerly winds today with peak wind conditions between 04/1900z to 05/0100z. Frequent gusts 20-25 mph will occur. Showers will also occur across the entire NR today. Some stronger showers will be capable of producing gusty outflow winds over 45-50 mph. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...Lake Wind Advisory from 3 PM this afternoon to 10 PM MDT this evening for Flathead/Mission Valleys. ID...None. && $$
