Area Forecast Discussion
National Weather Service Salt Lake City UT
953 AM MDT Sun Mar 11 2018

.SYNOPSIS...A disturbance over south central Utah this morning will
track eastward to the 4 Corners by this afternoon. In the wake of
this disturbance, strong ridging aloft will develop across the
Great Basin for the first half of the week.


.DISCUSSION...Short wave disturbance moving across south central
Utah this morning will exit the region by late this afternoon.
Improving conditions are expected over southwest Utah by midday
and over the southeast this afternoon. Snow amounts above about
8000 ft have been quite meager so far and with the storm system
moving away little additional snow is expected over the southern
mountains. SR-14 near Duck Creek is already mainly wet at 9700 ft.
Have updated forecast to end or reduce PoPs across southern Utah
for this afternoon.

Farther north, the high clouds have thinned across the northern
portions of the CWA so updated to have partly sunny skies
mentioned rather than cloudy or mostly cloudy. Although some areas
are currently experiencing mostly sunny skies this morning there
is mid level moisture that the models are insisting will form a
cloud deck this afternoon. Satellite is showing this cloud deck
over the western valleys from west of Delta to Dugway, but latest
imagery is showing this area is starting to shrink. May end up
with mostly sunny skies across northern Utah if this trend

Gusty easterly winds near canyon mouths along the northern and
central Wasatch Front will end by  as the surface gradient
between Wyoming and Utah relaxes.


.AVIATION...The SLC terminal will see VFR conditions throughout the
day with some high clouds. Light winds are expected to become
prevailing northwesterly by 18Z.
