Area Forecast Discussion
National Weather Service Salt Lake City UT
1006 AM MDT FRI JUL 22 2016

.SYNOPSIS...A dry cold front will cross northern Utah this
afternoon through tonight. This will spread drier and slightly
cooler air across about the northern half of the area. High
pressure aloft will strengthen across the area early next week
bringing a return of hot weather.

&&

.DISCUSSION...An upper trof is moving into the nrn Rockies this
morning. A disturbance in the southwest flow out ahead of this
trof kicked off convection across nrn UT overnight that is
currently lifting off to the ne with subsidence in its wake
shutting down any lingering convection and clearing out the
clouds.

The surface thermal trof lays stalled across nwrn UT but should
push swd this afternoon as the dry cold front associated with the
nrn Rockies trof enters the state. There is a potential of
convection focusing along this boundary this afternoon as well as
terrain based airmass development to the south of it but much
drier air spreads in behind this boundary ending the threat of
convection across the north.

This boundary doesn`t quite sweep the moisture out of the state
with enough lingering across the south to keep a mention of
isolated convection over about the sern 1/3 of the CWA.

A new weak upper trof along the coast backs the flow to swly again
across the CWA on Sun with moisture beginning to spread back into
the south. This spreads north on Mon with tstms spreading back
into the nrn mtns and deeper moisture looks to spread into the s
again by Tue.

For now have updated forecast to reduce sky cover most areas this
morning. Raised pops this afternoon across the srn Wasatch Front
swwd into the west deserts. No additional changes planned.

&&

.AVIATION...Gusty southerly winds will persist at the SLC terminal
into the late morning. A later wind shift to the northwest is
expected between 19-20z. Ceilings will not be of concern through the
TAF period.

&&

.SLC Watches/Warnings/Advisories...
UT...None.
WY...None.
