Area Forecast Discussion
National Weather Service Salt Lake City UT
937 PM MDT FRI MAY 27 2016

.SYNOPSIS...Several weak disturbances will cross the region
through the first part of next week.

&&

.DISCUSSION...An upper trough rotating through the northern
Rockies has pushed a weak cold front south through northern Utah
this evening. Isolated showers continue across the north behind
this boundary, however these should continue to gradually diminish
through midnight. Further south, a few showers also continue to
roam across southwest and south central Utah this evening, and
again should continue to wane over the next couple of hours. Plan
to update grids/zones to reduce evening pops accordingly.

The northern Rockies trough is forecast to lift northeast and away
from the region during the day Saturday, while a weak upper low
develops along the coast inducing shortwave ridging downstream
across the forecast area. Despite this ridging, lingering moisture
coupled with daytime heating will allow for another round of
afternoon and evening convection across much of the area.

This upper low is forecast to trek inland and across the forecast
area Sunday likely resulting in better areal coverage of
convection Sunday afternoon and evening, before a drying trend
begins Memorial Day in response to upper ridging amplifying across
the Sierras/Great Basin.

&&

.AVIATION...An outflow boundary stalled just south of the terminal
and is currently dissipating, which will likely result in
northerly winds continuing at KSLC through at least 05z. There is
a 30 percent chance these winds remain northerly through the
overnight hours. Otherwise VFR conditions will prevail with only a
10 percent chance of thunderstorms impacting the terminal through
the remainder of the evening and overnight hours.

&&

.SLC Watches/Warnings/Advisories...
UT...None.
WY...None.
