Area Forecast Discussion
National Weather Service Salt Lake City UT
1004 AM MDT Sat Apr 29 2017

.SYNOPSIS...The upper low over northwestern New Mexico will move
slowly east into the southern Rockies today. A series of weak
weather disturbances will graze the area Sunday night through the
early portion of the upcoming week. Strong high pressure aloft will
finally reach the area around the middle of the week.

&&

.DISCUSSION...The upper low centered over northwestern New Mexico
this morning is expected to shift east out of the area through the
day. In the meantime, some moisture continues to wrap into east-
central through southwest Utah mainly in the form of clouds, with
little or no precipitation being generated. Otherwise, a northerly
pressure gradient remains in place which is producing wind gusts of
25-25 mph in many areas. However, canyon/downslope winds across the
northern Wasatch Front and in Washington County never got
particularly strong, although brief gusts 40-50 mph were reported
overnight. These winds are no longer expected to reach advisory
criteria, so the Wind Advisories have been allowed to expire.

The back edge of the upper low will cross Utah this afternoon, with
a small chance of producing a few showers across the higher terrain,
otherwise sunny to partly cloudy skies are expected in most areas.
The sun combined with a general warming of the airmass will lead to
warmer afternoon maxes, although they will remain below normal.
However, some of the colder valleys will have a chance to see a hard
freeze tonight, especially those across central and southwest Utah,
as high clouds should begin spreading into the northwest tonight.

Updated the forecast mainly to reduce PoP/Sky for the rest of the
morning.

&&

.AVIATION...Winds at the KSLC terminal will remain primarily light
and variable or a light northerly through 17-18z prior to becoming
northwesterly above 7 knots between 18-19z. VFR conditions will
prevail through he valid TAF period under largely clear skies.
