Area Forecast Discussion National Weather Service Pocatello ID 126 PM MDT Thu Aug 22 2024 .DISCUSSION... Hot, dry and windy is the theme for much of the day today before things change quite a bit for the weekend. For the rest of today, expect S/SW winds to remain breezy through the afternoon, likely subsiding a touch overnight, before ramping up once again throughout the day Friday. Precipitation will move north out of Utah during the late afternoon potentially sparking some showers and thunderstorms across the easternmost portions of the forecast area. Coverage looks rather isolated however and hi-res CAMs have differences in opinion on timing and coverage. Nevertheless, it will be possible. A better surge of moisture looks to push into the area after sunrise Friday bringing another round of showers and isolated/scattered thunderstorms which will likely linger into the evening hours. Thunderstorm coverage looks like it'll primarily be focused in the eastern highlands although we could get some tstms into the Snake Plain and central mountains as well. Thunderstorm chances and coverage will increase the further east you go, closer to the Wyoming border. These storms will be possible of producing gusty winds and some small hail. In addition to the precip, winds will be quite breezy tomorrow regionwide. Accordingly, a Lake Wind Advisory has been issued for the American Falls Reservoir throughout the daylight hours tomorrow to account for this. The winds and precip will slowly taper off as we move into the late evening Friday and head towards Saturday AM. On Saturday, the weather will turn noticeably cooler for the first time in a few months. An upper level trough will begin to exert its influence across much of the Pacific NW bringing increased cloud cover and much cooler temperatures. Models have come into agreement a larger mid-level low splitting into two with one piece heading north into British Columbia with the other hanging around in southern Oregon/northern California. The northernmost feature appears to be taking much of the moisture with it on Saturday so PoPs have trended down quite a bit over the last few forecasts. Saturday looks mostly dry now for much of the region outside of some shower chances across the central mountains. Sunday looks like we'll get a bit more moisture in here allowing for PoPs regionwide but QPF is not overly impressive. What this feature will bring though is much cooler temperatures for the weekend with highs expected in the 60s and 70s in the lower valleys and even cooler across the higher terrain. Saturday also looks a touch breezy as well (15-20 mph) so that combined with the cooler temps will certainly bring a touch of fall to the region. Overnight lows in the 30s and 40s for most spots also will serve as a reminder that autumn is quickly inching closer. As we move into the workweek, the trough will lift allowing temperatures to gradually climb Monday and Tuesday back a bit closer towards normal and keeping things mostly dry. It does appear that the warmup will be short-lived though as models show yet another trough sweeping down out of western Canada on Wednesday and Thursday and this would bring us another drop in temperatures for midweek. As of now, it doesn't appear that it will be quite as cool as what we're expecting for this weekend but that could still change. For now, the forecast calls for highs generally in the 70s in the lower valleys though. McKaughan && .AVIATION... VFR conditions this afternoon with skies remaining mostly clear although clouds cover and precip chances gradually begin to increase during the evening and overnight. Winds will remain breezy for much of the period as we being to feel the influence of an upper level trough that will impact the area through the weekend. Breezy S/SW winds in the 15-25kt range with even higher gusts are expected. They'll likely lessen a touch overnight, but not much, before increasing once again for much of the day Friday. Looks like precip will avoid most terminals this evening and overnight but could sneak in to KPIH, KIDA and KDIJ by late morning/early afternoon tomorrow. Still a bit of uncertainty though so the forecast remains dry, for now, but could need VCSH/VCTS for the 00Z forecast. McKaughan && .FIRE WEATHER... Red Flag Warnings continue this afternoon until 9PM for Fire Zones 422, 425, 427 and 476 as breezy winds and low RHs will combine for critical fire weather conditions. Zone 410 will see the Red Flag continue in to the early AM hours as the dry, windy weather early transitions to some thunderstorm potential later tonight and overnight. It looks rather isolated in coverage and things may even be trending a bit drier but for continuity and messaging sake, will let it ride as is. Winds will remain breezy into the day tomorrow and may be even windier in some spots. The big difference will be increased RHs as moisture surges into the region. The western half of the region will be driest, namely 425, 427. 422 and 475 but it does appear RHs will remain above 15% for much, if not all of those areas tomorrow, so not planning on any Red Flags at this time. Much further east, RHs are much higher but thunderstorms will be the greater threat. That being said, coverage looks isolated to scattered, at best. 411 probably has the best chance for seeing SCT coverage but parts of 413 and 410 will as well. Nevertheless, after coordination with EIIFC about the threats for tomorrow, decided to hold off on a RFW. Things will be much cooler as we move into the weekend and early next week with even some snow possible above 9000 ft or so. Any precip will likely be more showery in nature and not expecting much tstm potential Saturday and beyond. That being said, no significant fire weather concerns in the extended portion of the forecast at this time. McKaughan && .PIH WATCHES/WARNINGS/ADVISORIES... Red Flag Warning until 9 PM MDT this evening for IDZ422-425-427- 476. Red Flag Warning until 4 AM MDT Friday for IDZ410. &&
