Area Forecast Discussion
National Weather Service Salt Lake City UT

.SYNOPSIS...An unseasonably warm southwest flow will exist across
the area this weekend. Moisture will spread north into Utah late
Sunday, and will continue to increase into early next week. Drier
conditions will return for the middle of the week.


.DISCUSSION...Southwesterly flow aloft remains in place over Utah
this evening. Models indicate heights will be slowly rising through
the night as the ridge bulges across the area in response to a
deepening storm system off the West Coast. Breezy southwest winds
this afternoon across portions of southern and west-central Utah
have diminished with the loss of daytime heating, with the exception
of a few exposed spots and high-elevation ridges. Meanwhile, high
clouds continue to spread into northern and central Utah. Overnight
mins should again trend warmer tonight due to the warm airmass in
place and the high clouds. However, the clouds are much thinner and
across the southern/eastern portions of the forecast area so
temperatures may remain on the cooler side there.

Moisture is still expected to work its way north into Utah tomorrow.
This moisture will interact with an approaching storm system to
bring precipitation to the area mainly tomorrow night through Monday
night. However, models have trended downward in QPF and coverage may
end up a bit more limited due precipitation becoming more showery
rather than steady rain.

Updated earlier to adjust Sky/winds through tomorrow morning and
made an additional update to adjust T/RH for the rest of the night.


.AVIATION...Southerly winds will continue at the KSLC terminal
through the rest of the night and is expected to strengthen by late
tomorrow morning. VFR conditions will prevail under increasing high
