Area Forecast Discussion National Weather Service Pocatello ID 239 PM MDT Mon Aug 1 2022 .SHORT TERM (Tonight - Tuesday)... Starting to see some more widespread CU development this afternoon across the central mountains as well as to the south across northern Nevada and Utah. Atmospheric moisture quickly increases throughout the rest of the afternoon and especially into the evening hours as the monsoonal push continues northward with PWAT values climbing well above 1" and into the 95th+ percentile climatologically. Initial thunderstorm development, especially in the mountains, will likely be of the dry variety but as the atmosphere quickly moistens, this will change to thunderstorms of the wet variety. Some of which may be sufficient rainfall produces so will have to keep an eye on precip accumulations once the event is ongoing. Hi-res CAMs this morning supported decent overnight coverage of convection with even some elevated thunderstorm potential during the overnight hours. As we move into Tuesday, primary focus area for precip shifts towards the SE corner of the region where the deepest moisture will be. Things remain unsettled throughout the day areawide however even across the higher terrain of the central mountains. Again, given the deep moisture in place late tonight but especially tomorrow, a close eye will have to be kept on storms for any localized flood threat. As far as temperatures are concerned, things remain quite hot across the area with widespread mid to upper 90s expected as more dense cloud cover looks to arrive past our peak heating time frame. Heat Advisory continues across the eastern Magic Valley towards Shoshone and into the Wood River Foothills. Things will be cooler by some 10- 15 degrees on Tuesday however as widespread clouds and rain will keep things noticeably cooler. ASM .LONG TERM (Wednesday - next Monday)... The forecast period starts with mainly zonal flow through the area, ECMWF and GFS can agree on that. Models also agree on a trough moving almost along the US/Canada border from west to east on Thursday and Friday. This will make for some breezy conditions both days and opens the door to bring in some more monsoonal moisture and the next best chance for widespread rain and convection to the area on Friday. A second trough follows a similar path through the weekend, but the GFS wants to keep it a bit farther north. To split the difference, keeping lower POPs in the forecast through Saturday and Sunday and even into Monday. As far as temperatures go, the ridge tries to build back in Wednesday into Thursday, but thanks to the end of the week and weekend troughs, it will break down a bit more again and keep our temperatures at or slightly below our average low 90s before the ridge begins to build in again and temperatures start to warm. Taking into account the CPC 6-10 Day outlook, we can expect at 40-50% chance of above normal temperatures as we get to the end of this forecast period. AMM/ASM && .AVIATION... For the 18Z TAFS through 18Z Tuesday Monsoonal moisture returns Monday afternoon, so expect an increase in cloud cover and each site contains VCTS for pop up showers and storms. VFR conditions are expected to continue, though cigs drop to around 7000ft. Winds pick up after 20Z with gusts between 15-20kts until around 06Z Tuesday. Expect winds to be a bit lighter at KSUN, staying around 10kts. Coverage of rain and storms picks up after 06Z Tuesday. AMM && .FIRE WEATHER... Monsoon moisture is moving up from Utah currently. Expect isolated thunderstorms mainly for our southern and northern areas. For our southern areas, zones 427 and 413, these storms late this afternoon into early evening could have locally heavy rain with them. Precipitable water amounts rise to around 1 to 1.25 inches by early evening along the Utah border. For our northern areas today, isolated thunderstorms are likely for zones 475 and 476 with moisture moving into the area combined with a weak short wave aloft. Thunderstorms look to occur by late afternoon and continue to early evening. For our northern areas, these isolated thunderstorms will be mostly dry and have gusty outflows up to around 40 to 45 mph. On Tuesday, look for a repeat of isolated showers and thunderstorms for most areas. Our southeast areas, zone 413, will likely just see isolated thunderstorms due to extensive cloud cover. Have held off on scattered thunderstorm coverage and thus any Red Flag warnings. However, expect moderate to heavy rain fall mainly along the Utah and Wyoming borders, especially for zone 413, on Tuesday. Wednesday looks dry with a return of isolated showers and thunderstorms, mainly for our southern areas, on Thursday and Friday. Also, Thursday and Friday look breezy with gusts of 20 to 30 mph. Temperatures do drop 5 to 10 degrees on Tuesday and Wednesday before warming back up by Friday and continuing into the weekend. Wyatt && .PIH WATCHES/WARNINGS/ADVISORIES... Heat Advisory until 9 PM MDT this evening for IDZ051-055-075. &&
