Area Forecast Discussion
National Weather Service Salt Lake City UT
957 AM MDT FRI MAY 27 2016

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

&&

.DISCUSSION...An upper trof sits over the Pac NW states this
morning with a difluent west to northwesterly flow over the
eastern Great Basin. Airmass moisture and instability in place
should allow scattered mainly terrain based convection to develop
today as this upper trof shifts east and the flow aloft backs.
This has already started across the nrn CWA from the Uintas wwd to
central Tooele county.

The greatest coverage will be over the mtns and ern valleys altho
the far north will also tend to have better coverage along an
approaching cold front. The convection will tend to diminish this
eve with the loss of daytime heating but a few cells could remain
active over the north in the vicinity of this frontal boundary
associated with the passing upper trof. This feature stalls across
central Ut thru tomorrow and the somewhat cooler and more stable
airmass to its north should suppress convection across the nrn CWA
tomorrow aftn.

Expect a return of convection area wide Sun as the flow backs
around again to southerly/southwesterly ahead of a closed low
over srn CA.

Updated earlier to make some adjustments in convective
distribution and sky cover today and this eve, and to add mention
of thunder for the rest of this morning. No additional updates
planned.

&&

.AVIATION...Southerly winds at the SLC terminal are expected to
switch to the northwest between about 17Z-19Z. There is a 20
percent chance of gusty, erratic winds at the SLC terminal today
from nearby showers and thunderstorms.

&&

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