714 FXUS65 KBOI 092024 AFDBOI Area Forecast Discussion National Weather Service Boise ID 224 PM MDT Sun Jun 9 2024 .SHORT TERM...Tonight through Tuesday night...Scattered showers and thunderstorms will continue through the early evening hours in the warm, moist and unstable air ahead of an upper level shortwave and surface cold front. There is a marginal risk that some of these thunderstorms will produce severe wind gusts and hail. Some of these thunderstorms will also produce brief heavy rain, but will be moving northeast at about 30 mph, which will limit total accumulations along their path. The thunderstorm activity is expected to diminish in Oregon after sunset and move completely east of our Idaho zones after midnight as drier air moves in behind the cold front. Monday will be dry with mostly clear skies across the area and temperatures will be several degrees cooler than today...though still above normal for this time of year. Hot weather returns on Tuesday under clear skies with temperatures climbing back into the upper 80s and low 90s in most valley locations and into the 70s and 80s in Mountain communities. .LONG TERM...Wednesday through Sunday...A dry west to east zonal flow pattern on Wednesday will become more southwesterly on Thursday and Friday. This will keep temperatures about 10 to 12 degrees above normal through Friday under mostly clear skies. Models are consistent in depicting an upper level trough moving into the PacNW Friday night through Sunday which will allow temperatures to cool back down to near normal during the upcoming weekend. There still does not appear to be much of a moisture tap with the incoming upper level trough and dry weather is likely to continue into Saturday with only a slight chance of precipitation creeping back into the forecast by Sunday. && .AVIATION...Mainly VFR.
