Area Forecast Discussion
National Weather Service Salt Lake City UT
1014 AM MST Thu Feb 22 2018

.SYNOPSIS...An active cold weather pattern will prevail through
the next several days as a series of weather systems move through
the region.


.DISCUSSION...A complex storm system with several lobes of energy
is developing across the Great Basin and northern California this
morning. The first, albeit weak, is along the Nevada/Utah border
and moving northeast. Weak lift is occurring ahead of it under a
diffluent flow aloft. The favored locations under southwest flow
aloft, such as Price and portions of the Wasatch Mountains and
Wasatch Plateau, have already been seeing some light snow this
morning and this should increase some as the day progresses. Have
updated the morning forecast to include this light snow as well
as increased the PoPs for the southern and central mountains for
this afternoon as a second lobe of energy crosses that region of
the CWA.

The maximum temperatures were tweaked some in several places due
to the cloud cover and expected snow. These include the Price area
where the cold air should remain in place with weak over running
all day. The other areas of concern were the GSL desert and the
CAche Valley where cold air will be trapped under a prevailing
cloud cover today. Lowered temps here by a few degrees.


.AVIATION...VFR conditions are expected at the SLC terminal
throughout the day with gradually lowering ceilings. The cigs are
expected to remain above 6000 feet AGL through about 00Z, but there
is a 30 percent chance lower cigs will come in earlier than
anticipated. Southerly winds are expected to persist throughout the
