Area Forecast Discussion
National Weather Service Salt Lake City UT
1030 PM MST Thu Feb 23 2017

.SYNOPSIS...A cold upper trough over the area today will shift
east on Friday. The next system will cross the area Saturday
afternoon and night, with yet another cold storm on tap for the
first part of next week.

&&

.DISCUSSION...A longwave trough encompasses the western CONUS this
evening, resulting in a moist and unstable northwest flow across
the forecast area. This continues to result in a band of snow,
potentially enhanced by the relatively warm waters of the GSL,
impacting the northern Wasatch Front and adjacent Wasatch Range
this evening. Have had reports of 2 to 4 inches thus far from
this band, and would suspect snowfall will linger through the
overnight hours likely impacting the morning commute Friday. The
large scale flow is not expected to veer much at all overnight,
thus it seems unlikely this band will shift south into the Salt
Lake Valley for more than a brief period here or there. Updated
the PoPs and Weather grids to reduce snowfall across areas south
of I-80.

&&

.AVIATION...Periods of MVFR snowfall can be expected at the KSLC
terminal through the overnight hours, with a 40 percent chance of
IFR or lower conditions developing at times. Any accumulation is
expected to remain less than 2 inches. Winds are expected to
remain northerly through the overnight hours.

&&
