Area Forecast Discussion National Weather Service Pocatello ID 147 PM MDT Mon Aug 28 2023 .SHORT TERM...Tonight and Tuesday It has been a rather quiet day across eastern Idaho as weak ridging remains in place allowing for mainly clear skies and light winds. This will continue into the overnight as well but overnight lows will run on the warmer side of normal by some 5-10 degrees. Things change as we move into Tuesday however as a potent shortwave swings through the region tomorrow. Winds will be the biggest story as there won't be much precip with this feature, although we do expect some. Winds will flirt with advisory levels mainly in the Magic Valley and into the South Hills but for now look like they will stay just below thresholds. This will create some fire weather concerns with warm temps expected, see discussion below for more on that. Temperatures ahead of the front will warm significantly and we will likely climb into the lower 90s for highs in much of the lower valleys with mid to upper 80s in the mountain valley zones. Again, precip should be fairly limited and likely focused across the higher terrain, but it can't be ruled out down into the Snake Plain either. Cooler air will filter into the region behind the front as we move into Wednesday. McKaughan .LONG TERM...WEDNESDAY THROUGH NEXT MONDAY... Post-cold front, fairly strong SW winds will linger Wed especially up the Snake Plain corridor, peaking during the afternoon at 20 to 30 MPH with gusts to 40 MPH (lighter outside of this corridor). A Wind Advisory might be needed for the Arco Desert region, while speeds further south may hold just shy of meeting Lake Wind Advisory criteria/creating dangerous waves on American Falls Reservoir. The other sensible wx impact post-front will be a noticeable drop in temps with highs only topping out in the upper 60s to mid 70s Wed afternoon, about 15 degrees cooler than Tue! Right now, it looks like Wed and Thu should hold dry for our region. As we head toward Fri, however, a fresh low pressure system will drop south along the PacNW coast, stall over Oregon/nrn California, and then potentially eject inland sometime over the weekend. Ahead of it, deep S/SW flow will draw increasing moisture/PWATs northward into our region with increasing chances of daily showers/t-storms from Fri onward. A modest warming trend is also likely until the low (or eventual open trough axis) pushes east of our CWA Sun or Mon. The afternoons will be a bit breezy until the system pushes east as well. 01 && .AVIATION... VFR conditions expected to prevail through the day and into the overnight with light winds and mostly clear skies. Things become a bit breezier after daybreak tomorrow but especially after 18Z as a frontal boundary is poised to move through the region. Winds will get breezy areawide. Precip will be fairly limited with this and primarily focused in the higher terrain potentially impacting KSUN and KDIJ but this is still just outside of the current forecast period. McKaughan && .FIRE WEATHER... Weak ridging over the Great Basin and nrn Rockies today will break down and surrender to an approaching low pressure system. This system will track east from WA to MT Tue and Wed, with a cold front swinging through SE Idaho Tue eve. Breezy winds on the order of 20- 25 MPH gusting over 35 MPH are expected for nearly all zones (lower along the WY border) Tue afternoon into Tue night, continuing Wed across most of Zones 425, 476, 410, and 411, direction SSW ahead of the front turning into the WSW behind it Tue eve and beyond. Right now, the only zone where decent coverage of critical RHs will overlap with the winds is Zone 425, so after coordination with NWS Boise, SCIIDC, and the Great Basin GACC, we have issued a RED FLAG WARNING for this zone from 3 PM to 9 PM Tue. The overall duration of true meteorological Red Flag conditions is a bit limited as it will take some time for winds to increase Tue afternoon, and then RH values will moisten rapidly during the eve as diurnal temps drop even as strong winds continue into the night. If any fires ignite, partners should bear in mind that gusty post-frontal winds will continue well beyond 9 PM. This system will also bring isolated t- storms Tue afternoon and Tue night regionwide, perhaps sct in coverage in Zones 475, 476, and 411. Storms will generally lean dry and gusty. RHs will improve slightly Wed/Thu with no storms currently expected, before a deep south flow ahead of our next low pressure system transports increasing moisture northward Fri into the weekend. 01 && .PIH WATCHES/WARNINGS/ADVISORIES... Red Flag Warning from 3 PM to 9 PM MDT Tuesday for IDZ425. &&
