999 FXUS65 KBOI 070222 AFDBOI Area Forecast Discussion National Weather Service Boise ID 822 PM MDT Sat Jul 6 2024 .DISCUSSION...Today was 5-10 degrees above normal in most areas. The hottest temps were in SE Oregon where Burns tied their record high for the day at 102 degrees. Ontario was also 102, and the hottest official observation was 103 at Rome. The forecast for Sunday is for most locations to be a few degrees cooler than today, but it will still be hot. Monday will see about a 5 degree increase from Sunday, and then we should gain another 5 degrees Tuesday. The Excessive Heat Watch will remain in place for now. No changes are needed this evening. && .AVIATION...VFR and mostly clear. High density altitude due to hot daytime temperatures. Surface winds: W to NW 10-20 kt with 20-30 kt gusts through 07/03Z, then becoming variable less than 10 kt. Winds aloft at 10kft MSL: NW 15-25 kt. KBOI...VFR and clear. High density altitude due to hot daytime temperatures. Winds NW 8-12 kt through 07/04Z, then variable around 5 kt overnight. && .PREV DISCUSSION... SHORT TERM...Tonight through Monday night...Breezy northwest winds will continue through this evening as a system passes by to the northeast in Montana. Winds should subside late this evening as the upper level ridge off the coast begins to move inland. As it moves inland, temperatures aloft warm substantially by Monday into Tuesday, with the hottest temperatures of the year so far. LONG TERM...Tuesday through Saturday...Multi-day 100+ high temperatures are forecast throughout the week with the strong upper ridge dominating across the region. Near record highs possible from Tuesday through Thursday. An Excessive Heat Watch remains in effect for all of southeast Oregon and southwest Idaho. Some relief in the mornings as lows are generally 35-40 degrees less than afternoon highs, thanks to the very dry conditions. Drier air prevails, although models continue to hint at some increasing high- level moisture later in the week. There is some indication for showers/storms next Saturday evening, but the setup is very marginal and could easily disappear in following forecasts. && .BOI WATCHES/WARNINGS/ADVISORIES...
