Area Forecast Discussion
National Weather Service Salt Lake City UT
946 PM MST Wed Feb 15 2017

.SYNOPSIS...High pressure aloft will maintain dry and mild
conditions across the region tonight. Southwesterly flow will
develop Thursday, followed by an active pattern late in the week
into early next week.


.DISCUSSION...An upper level ridge remains in place across Utah this
evening while a trough approaches the West Coast. Until the trough
ejects across northern Utah beginning late tomorrow afternoon, dry
and stable conditions will persist. Although cirrus clouds have
started to move into northwestern Utah and will gradually increase
in coverage overnight, they should remain fairly thin through the
night. However, these clouds combined with increasing southwesterly
flow aloft and the continued warming of the airmass are expected
keep overnight mins a bit warmer tonight.

The trough will bring light valley rain and mountain snow to the
area tomorrow night, mainly across northern Utah. This marks the
start of an extended period of unsettled weather with a series of
storm systems expected to cross the area through the end of next

Made minor updates mainly to tweak overnight mins and sky cover.


.AVIATION...Southerly surface winds will become established at the
SLC terminal by 06Z. Clouds will increase overnight and Thursday,
but ceilings will remain well above 7000 feet through 18Z.
