Area Forecast Discussion

.SYNOPSIS...An upper trough will cross the Great Basin today.
High pressure aloft will return briefly on Sunday, followed by
another storm system for early in the upcoming week.


.DISCUSSION...A cool upper trof and its associated cold front
are making their way into UT this morning. The front sits from
near Milford to near Evanston with fairly widespread precip
filling in to the west of it. A vort max in the base of the trof
over srn NV will lift north thru UT today enhancing precip along
and west of the front.

Snow levels are near 6500 feet but traffic cams show roads running
just wet over Logan summit and expect a similar conditions once
the snow reaches summits farther south such as Parleys and
Soldier. Snow levels will lower a bit thru the day and the major
passes could become a little slushy but it appears the main impact
to travel today will be above these main routes. Will leave the
existing advisory in place for now.

Expect slow clearing from the west this afternoon but clouds and
rain most of the day in many areas will keep temps on the cool
side today.

The upstream ridge moves into the Great Basin tonight and across
our CWA on Sun. Models keep some low level moisture around across
the north tonight and Sun so expect some lingering cloudiness
across the northwest that will hold temps up a bit.

The ridge shifts east Sun night as the next trof moves inland with
precip chances increasing across the north overnight becoming
widespread on Mon.

Updated forecasts earlier to lower max temps for today a little
and raised pops in areas where rain had already begun. No
additional updates planned.


.AVIATION...Periods of rain will occur at the SLC terminal through
about 20-21Z with prevailing MVFR conditions although 30% of the
time cigs could go above BKN030. Winds will be northerly through
about 07-08Z before switching to southeast. There is a 30 percent
chance of winds shifting to southeast as early at 03-04Z.


UT...Winter Weather Advisory until 10 PM MDT this evening for
