Area Forecast Discussion
National Weather Service Salt Lake City UT
206 PM MDT Thu Jun 23 2022

.SYNOPSIS...A weak low pressure system will cross the area late
today through Friday, interacting with moisture in place to bring
a threat of showers and thunderstorms. High pressure will bring a
warming trend over the weekend.

&&

.SHORT TERM (Through 12Z/6AM Saturday)...A weak upper low,
currently noted over the western Great Basin, will continue to
move through the region through early tomorrow morning. As this
low moves through the region through the remainder of the
afternoon and evening hours today, it will combine with moisture
set in place from deep southerly flow and generate scattered
showers and thunderstorms across the northern half of the CWA.
Given the near surface/ sub- cloud environment is still dry
(~1200J/kg DCAPE), the main threat associated with these storms
will be gusty and erratic outflow winds in excess of 40 mph. With
the aforementioned low moving through the area in the late evening
and overnight, thinking that the threat for showers and
thunderstorms will continue through ~0300, especially for northern
Utah and southwest Wyoming. In general, this threat is expected
to stretch from the I-15 corridor westward and from ~US-6
northward. South and east of this area, afternoon convection in
southern and eastern Utah will maintain potential to generate
heavy rainfall and flash flooding through ~2100 MDT.

The upper low will drape a weak frontal boundary across the
northern half of Utah and southwest Wyoming by the morning hours
on Friday (700mb temps drop by ~3-4C). With the subtly cooler
airmass in place across the northern half of the CWA, temperatures
are expected to be cooler than Thursday by about 5F. Remnant
showers and isolated thunderstorms will be possible across the
northern half of the CWA before ~1500-1600 MDT as turbulent flow
combines with the lingering moisture. Locally heavy rainfall will
be possible, and may pose flash flooding threats to recently
burned areas. Heading through the remainder of the evening hours,
convection will largely taper off as more stable air builds in the
wake of the departing low/ wave.

For southern Utah, a largely dry day is expected on Friday.
An uptick in southwesterly flow aloft will be noted as the
aforementioned wave moves across northern Utah, filtering in drier
air over the southern half of the CWA. That said, lower level
moisture will linger and generate at least an isolated threat of
showers and thunderstorms during the afternoon hours, but the
threat of heavy rainfall and flash flooding will be much lower.
Near critical fire weather conditions are expected in far southern
Utah, however, large areal extent of such conditions are not
anticipated. Thus, fire weather headlines will not be made.
Moisture will flux back into the region by the weekend, bringing
more chances for daily showers and thunderstorms.

.LONG TERM (After 12Z/6AM Saturday)...The monsoonal pattern that
will effect the CWA during the short term period is expected to
persist and keep wet conditions through the weekend, mainly for high
terrain sites in central/southern UT and areas east of I-15. A NW
Pacific low is expected to form at the beginning of following work
week that will graze to our north, promoting mostly zonal/SW flow
aloft over the CWA by Tuesday. The zonal flow aloft over the CWA
will promote warming back into the region as most northern UT
valleys could creep back towards 100F and the remainder of the UT
and SW Wyoming being back within a couple degrees of seasonal
values. Remaining moisture from the monsoonal pattern combined with
favorable dynamics from the northern grazing low could continue to
kick off rounds of precipitation and thunderstorms for the CWA
through the end of the extended period but is more expected to be
more spotty/isolated.

Deterministic and ensemble members both agree on high pressure
persisting over the southern plains which will continue to push
moisture into UT. Ensemble members also keep moderate chances around
30-60% for precipitation to form for most of the days over the
extended. While there are no large risks within the extended, any
rain showers or thunderstorms forming within the monsoonal pattern
could make or add to any ongoing flood scenarios.

&&

.AVIATION...KSLC...VFR conditions will persist through much of
the TAF period for the SLC terminal. An area of low pressure moving
through the region will keep winds out of the south and gusting near
20kts during the afternoon. Additionally, scattered afternoon
thunderstorms are slowly developing across UT and while CIGS are
expected to remain above obscuration levels, potential storms and
showers could create short periods of MVFR/IFR conditions as well as
stronger and erratic wind gusts from storm outflow boundaries.

.REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions mixed with
brief MVFR/IFR conditions will exist for all of Utah and SW Wyoming.
A low pressure system moving through the region, promoting
southwesterly winds that could gust near 20-25kts for most locations
during the afternoon. This low is expected to help develop afternoon
rain showers and thunderstorms which could lead to short periods of
MVFR/IFR conditions from lower CIGS and even mountain obscuration as
well as gusty winds from potential storm outflow boundaries.

&&

.FIRE WEATHER...An upper low noted over the western Great Basin will
continue to weaken an move through the region later this evening
through tomorrow morning. As the wave moves through the area,
broad forcing will help generate shower and thunderstorm activity
across the northern half of Utah, bringing a threat for gusty and
erratic outflow winds, lightning, and isolated heavy rainfall.
Storms across southern Utah will generally decrease in coverage
and dissipate through the late evening hours, mainly following
sunset. With all the shower and thunderstorm activity, overnight
humidities are expected to make good to excellent recoveries.

Tomorrow, the aforementioned wave will depart the region through
the second half of the day, allowing any ongoing shower and/ or
thunderstorm activity across northern Utah to dissipate. A cooler
airmass will be noted across the northern half of Utah, allowing
for much more moderated minimum humidities from about Nephi
northward. For southern Utah, however, an uptick in southwesterly
winds will help bring in locally drier air. With this in mind,
elevated fire weather conditions are expected across southern Utah
tomorrow, with localized near critical conditions possible closer
to the Utah/ Arizona border region. No fire weather headlines
have been made at this time. Moisture is expected to flux back
into southern Utah and throughout the remainder of the area over
the weekend and increase the daily chances for showers and
thunderstorms.
