Area Forecast Discussion
National Weather Service Salt Lake City UT

.SYNOPSIS...High pressure will build into the region tonight
through Wednesday. The high will give way to the next Pacific
storm system that crosses the area late Thursday through Friday
night. High pressure returns for the weekend.


.DISCUSSION...A low amplitude ridge is centered over the west
coast this evening and is nosing into our CWA. The last of the low
topped convection over the east is dissipating and except for thin
cirrus over the north, skies will clear tonight.

The afternoon north winds have been dropping off across most of
the north but remain gusty across the south. These too should drop
off overnight but will stay locally gusty through gaps in
Washington Co into Wed morning.

The ridge advances over the next 24 hrs or so with the axis
shifting east of the CWA tomorrow eve. Temps tomorrow should warm
about 10 degrees from today with high clouds increasing from the
north during the afternoon.

The new 00z GFS is a little faster again with the next trof and
brings the cold pool farther east into UT but keeps the overall
idea of the closed low dropping south Thu night then east to near
4 corners by late Fri. Confidence remains higher in the more
consistent, and slower, EC solution.

Updated earlier to add mention of isolated thunder over the
northeast. Will update again to remove all pops and lower the sky
cover for tonight.


.AVIATION...VFR conditions will prevail at the KSLC terminal under
mostly clear skies through at least Wednesday morning. North winds
will gradually decrease through 07-09z this evening, then
gradually shift to light southeasterly.
