Area Forecast Discussion
National Weather Service Salt Lake City UT
854 AM MDT Fri Mar 23 2018

.SYNOPSIS...A weather system which has brought widespread valley
rain and mountain snow to the region will move away this
afternoon. A cold upper level trough along the Pacific Northwest
coast will move east and impact mainly northern and western Utah
and southwest Wyoming this weekend.


.DISCUSSION...Southwesterly flow aloft continues to prevail across
the Interior West this morning, downstream from an upper slow
spinning along the Pacific Northwest coast. A shortwave embedded
within this flow continues to fuel valley rain and mountain snow
across portions of both northern and southern Utah. As this wave
continues to rapidly lift northeast, drier air and subsidence in
its wake should bring a fairly quick end to precipitation later
this morning, with perhaps just some lingering showers continuing
into the afternoon.

Runoff from rainfall over the past 24 hours is resulting in
higher flows through area rivers and streams, particularly
normally dry washes and small streams across southern Utah,
however no mainstem river flooding is expected.

Will update later on this morning as precipitation ends to remove
PoPs and likely drop the going Winter Wx Advisory.




UT...Winter Weather Advisory until noon MDT today for UTZ007-008.
