Area Forecast Discussion National Weather Service Pocatello ID 138 AM MDT Sat Aug 17 2024 .SHORT TERM...Today through Sunday night. Monsoonal moisture will arrive this afternoon in the form of showers and thunderstorms. We'll see this activity arrive in the southern highlands and move northward this evening through the eastern highlands. The convection doesn't look too impressive on the 00z runs of the HRRR and 3km NAM, looks more like numerous showers with isolated thunderstorms bubbling up from Utah. As is the case many times with these strong monsoonal pushes, some models, mostly the HRRR, are showing showers and isolated storms continuing through the night as the convection becomes more elevated. Isolated to scattered thunderstorms looks likely across much of the region on Sunday although the coverage on the 00z runs looks more isolated than scattered but than can easily change. With precipitable water values around 1 inch, where storms develop there will most likely be some brief heavy downpours. However, flash flood potential looks low as we expect storms to be moving along fairly well. Temps through the weekend look near normal with highs around 90 for much of the Snake Plain and Magic Valley. .LONG TERM...Monday through next Saturday. Models have not changed much for next week. Pattern over our region remains favorable for monsoonal flow on Monday as a deep upper trough is expected off the coast of the Pacific Northwest with a ridge over the southern Rockies. This pattern should produce isolated to scattered thunderstorms, mainly during the afternoon hours. There is a marginal risk for heavy rain on Monday as precipitable water values are expected to be around an inch. However, widespread flooding looks unlikely as we expect storm coverage to be isolated to scattered. We may see a reprieve from the thunderstorm activity Tuesday and Wednesday as models are showing some drier air working into the region from the southwest. However, it looks like we could get back into the monsoonal pattern late Wednesday or Thursday. Temperatures through much of the extended look near normal, but do cool off some later in the week as most model solutions begin to move the Pacific trough inland. && .AVIATION...Expect breezy conditions to develop this afternoon at most TAF locations. 20 to 25 kt gusts are likely at PIH and IDA. SUN will likely become upvalley this afternoon with a sustained 10 kt wind. Gusts of 15 to 20 kts are possible at SUN which could impact incoming flights. Shower activity is possible at TAF locations, mainly after 03z tonight. && .FIRE WEATHER...Near critical fire conditions are likely this afternoon across the south hills into the Magic Valley and through fire zone 422. Wind gusts this afternoon are in the 20 to 30 mph range which would support red flags, however humidities are not quite there. Generally looking at humidity values around 20 percent. With that said, there could be isolated spots that reach red flag thresholds but currently don't think we'll see criteria met over a substantial portion of South Idaho. Storms are expected to bubble up from Utah in fire zone 413 late this afternoon. However models are only suggesting isolated thunderstorm coverage with scattered showers. && .AIR QUALITY...HRRR smoke model shows improvement in air quality throughout the day across Custer County as the flow becomes more southerly. By this evening the vast majority of central and east Idaho should be experiencing good air quality, as long as there are no new starts. This pattern should stay in place through Sunday. && .PIH WATCHES/WARNINGS/ADVISORIES... None. && 13
