197 FXUS65 KPIH 070403 AFDPIH Area Forecast Discussion National Weather Service Pocatello ID 1003 PM MDT Sun Jul 6 2025 ...NEW AVIATION... .KEY MESSAGES... - Today will be the last day (for a while) for near normal temperatures with highs only in the 70s and 80s. - A warming trend is expected with very hot temperatures this coming week. Temperatures will return to the mid 80s to mid to upper 90s and even approaching 100 for lower elevations by next Tuesday and Wednesday. - A trough/weak upper level low moving through late Tuesday into Thursday will bring breezy conditions and afternoon, mostly mountain, dry isolated thunderstorms. && .SHORT TERM /THROUGH MONDAY NIGHT/... Issued at 119 PM MDT Sun Jul 6 2025 You`d be hard pressed to find clouds this afternoon when looking at visible satellite imagery. There are a few up towards Monida Pass and across the higher terrain of the central mountains but they are few and far between. This will be the norm over the next few days as high pressure remains in place, and builds further, as we move through the next few days. Under the ridge, skies will remain clear and precip free along with light winds and gradually warming temperatures. We will climb into the low to mid 80s across lower elevations today before the day is over but will begin to crank up the heat starting tomorrow as low 90s return in parts of the Snake Plain and Magic Valley. && .LONG TERM /TUESDAY THROUGH SUNDAY/... Issued at 119 PM MDT Sun Jul 6 2025 Not much changes as we get into the extended portion of the forecast period. The ridge will remain in place across the Four Corners region with H5 heights rising even more as we get in to Tuesday and Wednesday. These appear to be the hottest days of the week with mid to upper 90s forecast across the lower elevations. Models may have trended down a degree or two over the last 24 hours but it`s still going to be hot regardless. A shortwave will sweep through the region late Wednesday and into Thursday and this feature COULD spark a shower or thunderstorm across the central mountains on Wednesday but chances seem too low (less than 15%) to include in the forecast at this time. Winds will pick up as this feature approaches and will continue into the day on Thursday which could lead to some fire weather concerns both afternoons. Temps will drop a touch behind this shortwave, closer to normal, which means mid to upper 80s for highs on Thursday and Friday which precip chances remain very low. As we approach next weekend, models signal towards ridging building back over the area which would keep things dry and allow temps to return back into the 90s across lower elevations. Anybody hoping for widespread precipitation anytime soon looks like they`re going to be waiting awhile. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1002 PM MDT Sun Jul 6 2025 VFR weather with a few mid level clouds around for the next 24 hours. For SUN, there will be a window from very late morning through mid afternoon where southerly winds COULD be strong enough to impact air traffic. && .FIRE WEATHER... Issued at 119 PM MDT Sun Jul 6 2025 High pressure currently locked in over the northern Rockies and the Great Basin means a warming and drying trend into Wednesday. Afternoon high temperatures in the 90s at low elevations will return Mon, then Tue and Wed should be near record heat. This will mean a drop in afternoon humidity with widespread low elevations drying to below the critical threshold of 15 percent. The strong heating will make the instability in the afternoon quite high, with mixing heights getting rather large even for this time of year for Tue and Wed. On Wed night, an upper level trough should push through southern Idaho, bringing back a thunderstorm and shower threat, increased wind on Wed, perhaps enough for a critical fire weather day, but then a cooling trend starting Thu. Expect stronger wind from Thu onwards as warming and drying return. && .PIH WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...McKaughan LONG TERM...McKaughan AVIATION...Keyes FIRE WEATHER...Messick
