Area forecast discussion, May 6, 4:03 PM MDT, 11 hours 19 minutes before
Area Forecast Discussion...CORRECTED National Weather Service Salt Lake City UT 403 PM MDT Fri May 6 2022 .SYNOPSIS...A series of storm systems will keep northern Utah unsettled this weekend while southern Utah remains warm and dry with gusty winds. An active pattern will continue next week. && .SHORT TERM (Through 12Z Sunday)...Utah and southwest Wyoming are under a roughly zonal flow this afternoon between a weak wave that grazed northern Utah overnight and a second system moving onshore along the Pacific Northwest coast. The passage of a boundary has curbed the warming trend over northern Utah, though temperatures remain 10-15F above seasonal normals. Over southern Utah, temperatures have continued to rise, with maxes warming to 15-20F above normal for this time of year, approaching record territory in some locations. The Pacific Northwest storm system will make its way across northern Utah tonight into tomorrow. Disorganized as it comes through and not accompanied by much moisture, any precipitation associated with the system will be light and primarily confined to the higher terrain. Of greater impact will be gusty southerly winds ahead of the front during the day. Most guidance indicates 700 mb winds peaking at 50-55 kts over southeast Utah Saturday afternoon, with much of that easily making it to the surface. With high confidence in these winds being strong enough to cause travel impacts, issued a Wind Advisory for much of Saturday for south central and southeastern zones, including the Lake Powell area. Passage of the associated frontal boundary through northern Utah will also bring noticeable cooling, with maxes running around 10F cooler than values observed today. Some cooling is also expected over southern Utah, but should only be a few degrees or so. .LONG TERM (After 12Z Sunday)...The extended period will be based around a trough feature centered over the western United States. Starting Sunday we expect mostly zonal flow aloft to slowly turn to southwesterly and to strengthen, specifically over southern UT as the trough begins to deepen and amplify over the west coast. The associated low pressure system with the trough is expected to sit over the region through much of the extended keeping the CWA breezy, slightly cooler and driving spotty precipitation for areas in northern and central UT as well as SW Wyoming. The main risks for this incoming trough will be mostly for strong southwesterly wind gusts with the strongest winds coming on Sunday and Monday. Winds could reach and exceed advisory levels, particularly for high terrain areas in southern UT, but southern valleys should expect consistently breezy winds over this period as well. Sunday and Monday are also the best chance for any precipitation to form for northern and central UT as an enhanced baroclinic zone moves in and provides the best dynamical forcing. QPF values have slowly backed off over the last few days due to the westward positioning. This will lead to moreso spotty precip chances for not only Sunday/Monday but the entire extended. With cold air overhead the mountains could see a few inches of accumulating snow while the valleys see more of a mix of rain and snow with any accumulations sticking to grassy surfaces and likely melting relatively fast. Any afternoon showers, particularly on Sunday, Monday and even Tuesday that develop could form weak isolated thunderstorms as well. While a mixing of cloudy skies will likely keep us more mild overnight during the extended there is the potential for the abnormally cold airmass to drive borderline freeze risk conditions for various valleys with agricultural interests across the CWA on Monday and Tuesday nights. As model guidance has gained confidence on the trough's development occurring along the Pacific west coast, confidence has lessened in the chance for convection to form over the week with about 50/50 split at the moment. However, both deterministic and ensemble models drive the best chance for precip on Sunday and Monday with about 70% of members showing a wet solution. Thursday is also gaining some confidence with 70% of members showing a good chance for precip but also holds some uncertainty in the trough's pattern as it weakens, which will play a big role in the possibility for convection. && .AVIATION...KSLC...VFR conditions will be maintained over the KSLC terminal through the valid TAF period under increasingly cloudy skies. Light northerly winds, with periods of variable flow, will continue through ~03Z before returning to a southern flow. A cold front will push into the area and bring another northerly wind switch between 09-10Z. CIGs will drop to ~10kft AGL. There is a 30% chance of local mountain obscuration as showers develop early tomorrow morning. .REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions under increasingly cloudy skies will prevail across much of the area throughout the 24-hour period. A cold front will move into northern Utah after ~05-06Z, bringing a shift to northwest winds for most areas north of ~KPVU by 09-11Z. There is potential for strong wind gusts over northwest Utah following the frontal passage, where gusts as up to 35kts may be possible for KENV. Otherwise, expect CIGs to linger around 10kft AGL, with local terrain obscuration possible from KPVU northward from ~06Z onward as showers develop. && .SLC WATCHES/WARNINGS/ADVISORIES...
