Area Forecast Discussion...CORRECTED
National Weather Service Salt Lake City UT
252 AM MDT Wed Apr 17 2024

.SYNOPSIS...A weak, mainly dry cold front will cross into northern
Utah this morning and eventually become quasi-stationary across
central Utah. This front will weaken with time through Friday.
Expect gradual warming into the weekend and early next week.

&&

.SHORT TERM (Through 12Z Friday)...A mainly dry cold front will
cross into northern Utah this morning into early this afternoon.
This cold front will eventually stall across central Utah as the
associated shortwave trough shifts eastward. A few mountain snow
showers will be possible with this front across the northern
mountains through this evening. Any accumulation will be minimal.

This front will continue to weaken with time Thursday. A gradual
warming trend will be noted across northern and central Utah as
the front weakens. Little else of concern through the short term
forecast period.

.LONG TERM (After 12Z Friday)...Long term forecast period begins
with the forecast region placed largely in zonal flow aloft while
a remnant baroclinic zone gradually retreats northeastward out of
the area. This will allow afternoon highs from central Utah
northward to return to near climatological normal levels Friday,
while southern Utah will remain around 5 to 10 degrees above
normal. Thereafter into early next week, increasing H7
temperatures will promote further warming across the forecast
region, with afternoon highs areawide generally running around 7
to 15 degrees above normal. This translates to temperatures in the
upper 80s to around 90 degrees for Lower Washington County, and
temperatures generally in the 70s along much of the Wasatch Front.
NBM probabilities highlight around a 50% chance to see afternoon
highs at or above 80 degrees at KSLC on Tuesday.

Precipitation chances through the long term period will also
remain quite subdued. Some weak shortwave energy filtering through
aloft will help trigger some isolated diurnal showers along high
terrain Friday and Saturday afternoon, but most locations will
stay dry and just see some clouds filtering through overhead. By
Tuesday into the middle of next week guidance hints at potential
for a slightly stronger shortwave to work into the Great Basin and
nudge precipitation chances upward accordingly, but with
inconsistencies between modeled strength and timing, confidence
isn`t great in the details yet.

&&

.AVIATION...KSLC...A weak and mostly dry frontal boundary will
move through the area accompanied by a mix of VFR cloud cover and
an early switch to NW winds. Some gradual clearing then expected
through the day, with some modest wind gusts less than 25 kts
during the afternoon. Gusts diminish by Wednesday evening, with NW
winds further relaxing through the overnight hours.

.REST OF UTAH AND SOUTHWEST WYOMING...A frontal boundary will
gradually sink southward through the day, eventually becoming
stalled somewhere across central Utah. Precipitation chances
expected to remain fairly minimal with the front, and cloud cover
anticipated to remain VFR in nature. Following the frontal
passage, winds will acquire a more northerly component, with some
gusts picking up during the afternoon hours. For southern
terminals, winds follow a more diurnally typical pattern with some
high clouds filtering in throughout the TAF period.

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...None.
WY...None.
