Area Forecast Discussion
National Weather Service Salt Lake City UT
1044 PM MDT Fri May 18 2018

.SYNOPSIS...A weak ridge will move over the Great Basin Saturday
with another trough moving to central California by Sunday. A
southerly flow will prevail Sunday through Wednesday as this low
then tracks north northeast across Nevada into Idaho.


.DISCUSSION...A mean longwave trough remains in place across the
western CONUS this evening. A shortwave trough is slowly lifting
northeast away from the forecast area at the present time, while
another slow moving shortwave digs along the Pacific Coast. The
net result will be low amplitude shortwave ridging building across
the forecast area overnight through Saturday, resulting in only a
minimal threat for convection across the higher terrain of
northern Utah. Tweaked overnight PoP/Sky grids based on current
radar/satellite trends, otherwise going forecast looks to be in
good shape.


.AVIATION...South winds with VFR conditions will prevail at KSLC
through the overnight hours.
