Area Forecast Discussion
National Weather Service Salt Lake City UT
957 AM MDT Fri Oct 21 2016

.SYNOPSIS...High pressure will shift east today with a
southwesterly flow developing for the weekend. Moisture will
begin to spread into the region Sunday and will continue to
increase through Monday.


.DISCUSSION...The mid level ridge is centered overhead this
morning with clear skies across the CWA. The temps at 700mb have
warmed 6c at SLC in the last 24 hrs but do not expect this warming
to be fully realized at the surface today due to the continued
stable airmass in place limiting the mixing in the valleys.

Swly flow increases tomorrow and these winds should surface in the
aftn bringing better mixing and warmer surface temps even tho
700mb temps stay steady.

Latest models still bring moisture into the CWA from the southwest
on Sunday increasing thru Mon. Clouds increase Sun with a chance
of showers beginning late in the day over swrn UT. The heaviest
precip looks to be over the mtns and east on Mon into Mon night
and the GFS was generating over an inch of rain by Tue aftn in
some areas including Carbon and Emery counties.

Will be raising pops in the aftn forecast package for these areas
if daytime runs continue along this trend. For now, no updates


.AVIATION...Southerly winds at KSLC will be switching to the
northwest between 18z and 20z today. There is a 30 percent chance
winds will switch sooner around 17-18z.
