Area Forecast Discussion National Weather Service Salt Lake City UT 325 PM MDT Sun Jun 20 2021

SYNOPSIS. High pressure will amplify over Utah and southwest Wyoming tomorrow before a gusty southwest flow develops by Tuesday. Conditions will remain hot and dry to start the week, with high based moisture expected to return for the middle of the week.

SHORT TERM (Through 12Z Wednesday). The weak cold front that had been making its way across the area since last night has moved into northern Arizona this afternoon. Behind it, conditions are dry and stable over northern Utah and southwest Wyoming, with high temperatures running 5F or more below yesterday's maxes, but still 10F above seasonal normals. Cooling is much more subtle over southern Utah, and the front has provided enough instability for some cumulus over the higher terrain and a few patchy showers over southeast Utah. Any remaining convection is expected to dissipate by early evening.

As a trough starts to approach the Pacific coast tomorrow, high pressure will amplify over the forecast area Monday morning before the axis starts to shift east Monday afternoon. Because of this, southwest flow will be on the increase, initially over southwest Utah, spreading across much of the forecast area by Tuesday afternoon. With conditions remaining hot and dry, this will result in areas of critical fire weather conditions. See the fire weather section of the AFD for more details. The increasing flow will warm temperatures back to near record values over northern Utah by Tuesday. However, over southern Utah the slow approach of the trough will allow a slightly cooler airmass to start to advect in, so maxes there will be only about 5F above climo by Tuesday afternoon.

LONG TERM (After 12Z Wednesday). Critical fire weather conditions continue to be the primary concern early in the period, transitioning to potential for extreme heat by the weekend. A Fire Weather Watch is in effect Wednesday for areas of the West Desert and central Utah.

Global ensembles remain lockstep in nudging a low pressure system onto the CA coast early Wednesday. This system will usher in strong mid- and upper-level SW winds to the forecast area. Enough moisture advection in upper levels combined with increased instability will encourage high-based afternoon convection over the mountains of southern and central Utah, with potential for dry lightning. Mid- level moisture marches northward on Thursday to increase CAPE values and enhance the potential and coverage of afternoon thunderstorms across the high peaks throughout the CWA. Though little measurable precipitation is expected, temperatures will cool to a mere 5 degrees above normals during this latter half of the work week. Model agreement diverges on Thursday potential for critical fire weather conditions over southern Utah.

As the low retrogrades slightly westward, most models show a high pressure ridge quickly rebounding, returning a dry airmass and likely catapulting temperatures back to 10+ degrees above normal for the weekend. Ensembles also suggest lighter winds as the ridge axis develops directly over the forecast area.

AVIATION. KSLC . VFR conditions under largely clear skies are expected to be maintained over the KSLC terminal through the valid TAF period. Gusty northwesterly flow over the airfield will prevail through ~02- 03Z, decreasing in speed but remaining out of the northwest through 09Z. Thereafter, a return to light southerly drainage flow is anticipated.

Rest of Utah and southwest Wyoming . VFR conditions are expected through the valid TAF period. Gusty westerly/ northerly winds are anticipated from about KPVU northward through the remainder of the evening hours, but will decrease in speed around sunset. Scattered high-based cumulus across the southern half of Utah will prevail through the remainder of the heating hours, decreasing in coverage through the late evening. Expect winds below 12kts for most areas through the overnight hours.

FIRE WEATHER. Northwesterly flow aloft has temporarily developed across much of the region, which has allowed a more stable and slightly cooler airmass to spread across northern and central Utah. These northwest winds will be gusty at times through the evening, especially over northern and eastern Utah, combining with the dry airmass to produce areas of critical fire weather conditions.

High pressure will build across the district Monday, resulting in hot, dry, and stable conditions. As the ridge axis shifts east of the area Monday afternoon, southwest winds will increase over southwest Utah, resulting in areas of critical fire weather conditions. The gusty winds will spread over much of the district Tuesday, resulting in widespread critical fire weather conditions through Tuesday evening. This gusty southwest flow is expected to remain in place into Wednesday, and moisture within this flow may bring a return of afternoon thunderstorms to the higher terrain of southern Utah for Wednesday afternoon and evening, with some valley locations across central Utah possibly still seeing low enough relative humidity values for critical fire weather conditions.
