Area Forecast Discussion
National Weather Service Salt Lake City UT
1010 AM MDT THU MAY 19 2016

.SYNOPSIS...High pressure will shift east today ahead of the next
Pacific storm. This system will stall over the Pacific Northwest
through the end of the week.

&&

.DISCUSSION...Upper low clearly indicated on morning satellite
imagery across the Pacific Northwest along with a significant jet
streak rounding the base of the trough. This trough will slowly
dig southeastward and intensify through Friday and remain across
the Pacific Northwest/Northern California area into the weekend.

The associated cold front will approach the northwestern corner of
the state this afternoon. Ahead/near the cold front, expect
convection to develop this afternoon and evening. Expect well
mixed/dry subcloud environment/inverted V type profiles, the
biggest threat will be microburst winds associated with any
convection that develops. Though instability will be marginal for
more robust, organized convection but small hail will be possible
in some of the stronger storms. Expect at least a few reports near
60 mph this afternoon/evening...primarily across the Great Salt
Lake Desert...though the threat for gusty microburst winds extends
to the central/northern Wasatch Front/Cache Valley and adjacent
terrain. Any convection should quickly diminish after sunset with
the loss of daytime heating.

Forecast is on track and no updates are planned this morning.

High wind warnings and wind advisories remain in place across much
of the CWA for Friday afternoon/evening. Initial review of
available 12Z model guidance continues to support current
warnings/advisories.

&&

.AVIATION...Expect southerly wind gusts to continue at the SLC
Terminal through the afternoon and into the evening. A cold front
is expected to cross the terminal between 00-02Z. Thunderstorms
are possible in the vicinity of the terminal between 18-02Z. Any
thunderstorms will be capable of strong, gusty and erratic winds.

&&

.SLC Watches/Warnings/Advisories...
