939 FXUS65 KBOI 240820 AFDBOI Area Forecast Discussion National Weather Service Boise ID 220 AM MDT Tue Sep 24 2024 .SHORT TERM...Today through Thursday night...An upper level ridge centered directly over our area will move east today, allowing SW flow aloft to move in. This will help to increase temperatures through Wed, with readings around 15 degrees above normal Wed. This will also bring enough moisture to warrant a 15-30% chance of showers and a slight chance of thunderstorms to northern areas Wed late afternoon and night as a shortwave trough moves by. Breezy conditions will develop Wed aft/eve, especially in SE Oregon and in the higher terrain of SW Idaho. The cold front associated with that trough will move through Wed night, resulting in cooler temperatures (about 5 degrees above normal) Thursday. .LONG TERM...Friday through Tuesday...Relatively weak and dry flow aloft, changing from WSW to WNW through time, will dominate the long term period. No precipitation is expected. Temps will warm slightly Friday through the weekend to 5-10 degrees above normal before cooling back down to just a few degrees above normal Monday and Tuesday. && .AVIATION...VFR.
