Area Forecast Discussion National Weather Service Salt Lake City UT 430 AM MDT Fri Jun 14 2024

Above average temperatures remain in place today with an upper low bringing low to medium chances for isolated showers and thunderstorms over eastern Utah. Regional weather gradually changes through the weekend as a storm system develops over the West, bringing cooler temperatures late by early next week.

.SHORT TERM (Through 12Z/6AM Sunday)...An area of low pressure progresses across the region today, bringing increased moisture and low end chances for showers and thunderstorms over the eastern half of Utah. Cloud cover and stronger overnight winds associated with this area of low pressure have spread across much of the area late yesterday evening, and have contributed to high overnight low temperatures. As of 0400, temperatures at KSLC remain at 81 degrees... 8 degrees higher than the daily record high minimum temperature, and just 1 degree off from the all time record high minimum temperature. Similar temperatures are being observed across the Wasatch Front. As such, the existing heat advisories remain in effect through 6AM. It is unlikely that these headlines will need to be extended as temperatures gradually cool over the next few days as trough begins to develop over the West.

Today, temperatures will remain 5-10 degrees above average across the region today. Increased moisture associated with the aforementioned low will bring isolated showers and thunderstorms over the eastern portions of Utah this afternoon, however, there is very little potential for these showers to produce much precipitation. However, slow storm motion could allow for stronger storms to moisten up the sub-cloud environment more rapidly and allow for brief, but moderate to heavy, rainfall. Because of this, there still exists a non-negligible threat for flash flooding in slot canyons, dry washes, and slickrock areas.

Late this evening, an upstream trough will begin its progression inland and will bring significant changes by early next week.
Leading up to the arrival of the trough and its associated cold front, there will be increasing concerns for fire weather conditions (see "Fire Weather" portion of the discussion for more details). Gradual cooling of overhead temperatures is expected across at least the northern half of the forecast area up to the trough's arrival, resulting in cooler temperatures for Saturday from about Tooele County northward. For areas south of Tooele Co., temperatures will see minimal change, if not warming by a few degrees on Saturday. Breezy afternoon conditions are expected across much of the region on Saturday, but particularly across the southern half of Utah. Hot, dry, and breezy conditions will bring concern for fire weather headlines, however, recent models have backed off ever so slightly with winds, making Saturday more of a borderline fire weather day for the zones that currently have critically dry fuels. As such, have maintained Fire Weather Watches for fire zones 498 and 497.

.LONG TERM (After 12z/6AM Sunday)...A potent, spring-like cold front will bring temperatures near 10 to 20 degrees below normal by Tuesday, a great contrast to the heat we have seen in recent days.

On Sunday, a shortwave trough will be resting just off the coast of the PacNW. As it begins to push inland, pre-frontal southwesterly winds will increase on Sunday afternoon, especially across southern UT. Ensemble mean wind gusts are around 35-45 mph in this area mainly south of I-70. Monday afternoon wind gusts are likely to be even higher, reaching 40-50 mph just ahead of the frontal passage.
The 90th percentile wind gusts (a reasonable worst case scenario)
even approach 60 mph in isolated areas.

Just behind the frontal passage, gusty northwesterly winds are likely, along with a sharp drop in temperatures. The air mass will remain quite dry even with the front, despite the system's oceanic origins, with only a few isolated showers along the UT-ID border Monday evening. Tuesday high temperatures are likely to be 10 to 20 degrees below normal, translating to the upper-60s along the Wasatch Front and low-90s in St
more akin to highs in early May.

There is, however, still some remaining uncertainties in the forecast, mainly pertaining to timing of the frontal passage and the degree of cooling across the area. There are still 20% of members that favor a less aggressive cooldown, with 700-mb temperatures near contrast to the other 80% that suggest around -2C.

In summary, the biggest impacts with this system will be gusty pre- frontal southwesterly winds, below-normal temperatures, and areas of critical fire weather conditions (see Fire Weather section below).
Beyond Tuesday, temperatures will steadily increase once again.

KSLC...Southerly winds will continue through the morning, though speeds/gusts will gradually decrease after 12z.
Winds will then transition to northwesterly around 20-21z, returning to southerly around roughly 03-05z.

Southerly winds will gradually decrease through the morning, staying relatively light though favoring a southwesterly direction through the afternoon. Scattered showers and isolated thunderstorms are expected across eastern UT after roughly 18z. Any of these storms will be capable of producing gusty and erratic outflow winds.

UT...Heat Advisory until 6 AM MDT early this morning for UTZ101-102- 104>106.

Fire Weather Watch from Saturday morning through Monday evening for UTZ498.

Fire Weather Watch from Sunday morning through Monday evening for UTZ497.
