Area Forecast Discussion National Weather Service Salt Lake City UT 355 PM MDT Wed Aug 24 2022 .SYNOPSIS...A disturbance will pass through northern Utah through tonight, promoting widespread showers and thunderstorms. Drier conditions will build into northern Utah Thursday and Friday while central and southern Utah remains active. An area of low pressure moving into the Pacific Northwest Saturday and approach our area Sunday into early next week, but the track, strength and timing of this system remains uncertain at this time. && .SHORT TERM (Through 6AM/12Z Friday)...Early afternoon water vapor and upper air analysis depicts a shortwave located over northwest Nevada with an attendant jet streak located over NE Nevada. This feature is providing a source of large-scale ascent, which is maximized currently over SW and west-central Utah. Mid-morning convective activity that developed across the west deserts has continued to grow upscale as it has progressed into northern Utah, where widespread showers and isolated to scattered thunderstorms have developed. There is uncertainty as to how this activity might impact convective trends as we head through the remainder of the evening as at least modest subsidence and boundary layer stabilization appears to be occurring in the wake of this activity. ARW and NSSL WRF CAMs initialized closest to reality, and they both suggest widespead showers and thunderstorms will move from central Nevada across central Utah late this afternoon and through the evening hours, especially along/south of I-80. Farther south, convective initiation has been largely tied to terrain. CAMs have initialized better here, so have more confidence in their depictions - which suggest this convection will gradually move northward from their current locations. Merging cold pools could result in some deviant/random motions. An axis of PWATs in the 0.8-0.9" inch range now overspreads all of western Utah, mainly along/west of I-15. Thus, slow-moving training cells will have the potential to produce flash flooding, especially over burn scars, slickrock areas, normally dry washes, slot canyons and steep terrain areas. By this evening, CAMs appear to be converging on a solution that suggests numerous cold pools will converge across SW Utah, mainly across Washington and Iron counties between 6PM-10PM. This will bear watching. Farther north, convection associated with the above- mentioned shortwave will continue to gradually weaken overnight, but a few showers can't be ruled out through the night across northern Utah. Heading into Friday, northern Utah and SW Wyoming will reside within both a subsident regime as well as a dryer, westerly flow regime. Therefore, shower and thunderstorm coverage is expected to wane significantly here, with the exception of the Uintas and adjacent Uinta Basin. Farther south, moisture is expected to pool generally along/south of I-70/US-50, and scattered showers and thunderstorms are expected to develop during the afternoon and continue through the early evening. Given PWATs in the 150-175% of normal range (highest over SW Utah) a heavy rainfall threat will exist once again. Storm motions are expected to be generally light eastward, which could be problematic for those west-east oriented drainages. HREF 3-hr neighborhood probabilities of 1" of QPF in 3 hrs is maximized around 30% over south-central and SE Utah. Opted not to issue a Flood Watch at this time due to an anticipated largely isolated flash flood risk. This does not mean a flood risk does not exist as any slow-moving or training storms will be capable of producing flash flooding across sensitive areas. .LONG TERM (After 12Z/6AM Friday)...The extended forecast period remains mostly unchanged with some uncertainty to end the weekend and start of the following work week. Precipitation chances on Friday for areas of southern and eastern Utah remain while the remainder of the CWA looks to stay dry. Temperatures sit right around climatological norms with afternoon highs expected to be in the upper 80s to mid 90s for most valleys in Utah and SW Wyoming. A closed low pressure system is expected to develop over the extended and move on shore and eastward to our north by the start of the weekend. Its movement into the region is expected to promote upper level flow to be more zonal/northwesterly over Utah, moving dryer air into the region. This will keep the CWA mostly dry on Saturday with the potential for spotty terrain driven showers and storms. The growing effects of the closed low on Saturday are showing the potential for enhanced winds in model guidance, particularly over high terrain areas of Utah and SW Wyoming. Ensemble members have wind gusts of 25-30 mph over most those areas with some guidance having 35+ mph at Evanston which could be of risk for weekend travelers on I-80 in Wyoming. Sunday and into the beginning of the following work week there grows some uncertainty as the passing closed low is growing in model guidance as passing further south than originally expected. This more southerly track would allow for southwesterly flow to be promoted over the CWA and bring more moisture and better synoptic lift for widespread storms on Sunday into Monday and in some models that have the low progressing slow, possibly into Tuesday. After the passing closed low, model guidance is growing in high pressure building behind it over the CWA that will likely bring dry conditions across all of Utah and SW Wyoming by midweek. With showers and storms still likely in the forecast for areas in southern Utah we can't rule out the potential for localized flash flooding for different slot canyons, National Parks and recent burn scars. && .AVIATION...KSLC...Showers and thunderstorms with gusty outflow winds are expected through 01Z. Better chances for rain are expected from roughly 01-04Z. VFR conditions are expected to prevail, with slight chances for MVFR conditions with a stronger shower or thunderstorm. Dry conditions are expected through the overnight with light southeast winds. .REST OF UTAH AND SOUTHWEST WYOMING...Chances for rain will increase from 00-05Z throughout southwest Wyoming and northern Utah. Stronger showers or thunderstorms could cause MVFR conditions. VFR conditions are expected further south. Showers and thunderstorms will be more isolated and diminish after sunset throughout southern Utah. && .FIRE WEATHER...A trough of low pressure will drift across northern Utah tonight, interacting with a modest monsoonal surge to promote widespread shower and thunderstorms this evening along with an increase in humidity. Thunderstorms will be capable of producing heavy rain, gusty winds and frequent lightning. A drying trend will commence across the north for Thursday and Friday while increased moisture and shower and thunderstorm activity remains confined to mainly central and southern Utah through this time. By this weekend, models continue to indicate that an area of low pressure will drop into the Pacific Northwest Saturday. There remains quite a bit of disagreement on where this low will track and how strong it will be. There is a chance it tracks across northern Utah between Sunday and Tuesday. A farther north track through Idaho would result in dryer, warmer and breezier conditions while a low track directly overhead would likely result in cooler, showery conditions. Either scenario is still in play at this point. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...None.
