568 FXUS65 KBOI 101542 AFDBOI Area Forecast Discussion National Weather Service Boise ID 942 AM MDT Thu Jul 10 2025 .DISCUSSION...Dry and cooler conditions are expected today, with high temperatures running about 3 degrees below normal. A thick layer of smoke from wildfires in northern California and south- central Oregon was visible on satellite earlier this morning, but increasing northwesterly flow aloft is helping to push much of it south. As a result, mostly clear skies are expected across the forecast area by early afternoon. That said, some residual smoke remains possible, particularly if any new fires were sparked by yesterdays thunderstorms. We`ll continue to monitor smoke trends throughout the day. Winds will be breezy this afternoon, especially across the Snake River Plain east of Boise, where gusts of 25 to 35 mph are likely. No updates to the forecast are needed at this time. && .AVIATION...Generally VFR. Surface haze and smoke layers aloft near NV border, exiting toward NV today. Surface winds: W to NW 5-15 kt with 15-20 kt gusts, except 10-20 kt with 25-30 kt gusts for south- central ID. Winds aloft at 10kft MSL: NW-W 10-25 kt. KBOI...VFR. Surface winds: NW 8-14 kt, with gusts around 20 kt after 10/16Z. Weekend Outlook: VFR with smoke layers aloft. High density altitude due to hot temps, especially Sunday through next week. Surface winds: NW-W 5-15 kt with gusts 15-25 kt in the afternoons. && .PREV DISCUSSION... SHORT TERM...Today through Saturday night...The region will remain under a dry northwest flow today with temperatures 4-8 degrees cooler than yesterday. Breezy conditions across open terrain will bring gusts of 25 to 35 mph to areas south and east of Mtn Home through this evening. Friday and Saturday are dry with temperatures bumping up a couple of degrees each day as an upper ridge over the Desert SW flexes northward. Daytime mixing will bring northwest winds each afternoon with windier spots seeing gusts to 25 mph. LONG TERM...Sunday through Thursday...A large high pressure system developing over southern california will build into the entire western CONUS region, returning a warming and drying trend Sunday into next week. Valley daytime temperatures are expected to climb back into the upper 90s Sunday and generally remain in this range through Thursday. An upper trough digging down into the northern Rockies on Tuesday may bring some showers/thunderstorms in the higher elevations, but guidances do not favor any precipitation or much of a cooling trend at this time. Wednesday and Thursday will see a considerable guidance uncertainty over the arrival of another trough from British Columbia. For now, dry and warm conditions are expected throughout the long term period. && .BOI WATCHES/WARNINGS/ADVISORIES... ID...None.
