323 FXUS65 KBOI 101600 AFDBOI Area Forecast Discussion National Weather Service Boise ID 1000 AM MDT Mon Jun 10 2024 .DISCUSSION...Warm and clear conditions are expected for the next few days, with high temperatures in the valleys reaching the upper 80s-mid 90s each day. Low patchy clouds in the mountain valleys this morning will rapidly mix out by early afternoon today, and breezy westerly afternoon winds will increase by mid afternoon. No necessary updates to forecast. && .AVIATION...VFR and mostly clear. Monday will be breezy in the Magic Valley. Surface winds: generally NW 5-10 kt, except 10-20 kt from near KMUO east through KJER/KTWF. Winds aloft at 10kft: W-NW 10-20 kt. KBOI...VFR with some high clouds. Surface winds: NW 5-10 kt, then variable less than 5 kt. && .PREV DISCUSSION... SHORT TERM...Today through Wednesday night...Our upper level flow will be out of the northwest to start the short term, then shift to zonal Tuesday, then to just south of west Tuesday night through Wednesday night. This will be a dry flow, and no precipitation is forecast through the short term period. Winds will be breezy from around Mountain Home east into the western Magic Valley today, but otherwise winds will be light and follow typical diurnal trends for this time of year. Temps will be 5-10 degrees above normal today and Wednesday, with a warmer Tuesday (10-15 degrees above normal) sandwiched in-between. LONG TERM...Thursday through Monday...The upper flow will become more southwesterly Thursday as a large upper level low moves into position off the Canadian coast. This will bring warmer temperatures Thu (10-15 above normal) and Fri (5-10 above normal). As the upper system moves inland late Friday into Saturday, it is expected to push an initial cold front through the area Friday, followed by a stronger front Saturday. These will push temps down to just below normal Saturday and around 5 degrees below normal Sunday. These fronts look dry and breezy at this time. Models agree quite well into Friday, but differ in the strength of the weekend system. The latest EC depicts a strong trough passage Sunday, while the GFS holds it back until late Monday. At this time, a slight warming is anticipated for Monday in the NBM guidance, indicating that ensembles favor the EC timing over the GFS. && .BOI WATCHES/WARNINGS/ADVISORIES... ID...None.
