536 FXUS65 KBOI 052000 AFDBOI Area Forecast Discussion National Weather Service Boise ID 200 PM MDT Fri Jul 5 2024 .SHORT TERM...Tonight through Sunday night...A strong upper level ridge will bring increasingly hot temperatures to the area through the weekend as it drifts slowly east. Initially off the coast, it will move inland by Sunday night. The Excessive Heat Watch has been changed to a Heat Advisory for Harney and Malheur counties, along with the lower Treasure Valley of Oregon, for Saturday and Sunday. Temps will warm up even more going into the long term, and the Watch continues for most areas through next week. Winds will increase tomorrow afternoon/evening, especially in far SE Oregon and from near Mountain Home south and east, with gusts 20-30 mph. Winds will be considerably weaker Sunday. .LONG TERM...Monday through Friday...I know it is starting to sound like a broken record, but temps will continue to rise going into next week. The upper level ridge will continue to move slowly east, and will be centered over our area Tuesday and Wednesday. An Excessive Heat Watch continues for most of the area Monday through Friday, with Wed currently forecast to be the hottest day. Numerous daily records will be set, and several all-time-high records may be reached. It`s going to be a dangerous time for those without air-conditioning, and for those working outside. The watch will almost certainly be upgraded to a warning as we get closer in time. Multiple consecutive days of high heat take a cumulative toll on the body that can seriously endanger life. This is especially true for those with pre-existing health conditions, BUT AFFECTS EVEN FOR THOSE IN PERFECT HEALTH, if reasonable precautions are not taken. && .AVIATION...VFR under clear skies.
