National Weather Service Salt Lake City Utah
825 PM MDT sun Aug 28 2016

Synopsis...an upper level low pressure system over The Four
Corners area will move slowly eastward through Monday, as a ridge
of high pressure builds over the Great Basin. The ridge of high
pressure will remain over the region on Tuesday, before shifting
east.

&&

Discussion...evening water vapor imagery and objective analysis
depict an upper low spinning near The Four Corners region while
upstream a mid level ridge axis stretches inland across the
sierras and over much of the Great Basin. Northerly flow
downstream from the ridge axis has helped dry the airmass across
the forecast area. Isolated weak convection which fired this
afternoon over the terrain has since dissipated with the loss of
daytime heating, and will go ahead and update to remove evening
pops. This ridge axis is forecast to build eastward over the
forecast area Monday resulting in a slight uptick in Max
temperatures. Isolated convection will remain possible across the
higher terrain from the uintas southward.

&&

Aviation...northerly winds will Switch Back to the south at kslc
by 04z, after which southerly winds and VFR conditions will
prevail through the morning hours Monday.

&&

Fire weather...high pressure building into the district from the
west will enable a warming and drying trend to take form through
midweek. Outside of a few isolated buildups and weak storms over
the highest most prone terrain tomorrow dry conditions will hold
through the period.

The approach of an upper level disturbance originating from the
Pacific northwest midweek will aid to increase southerly surface
winds across the west beginning Wednesday. A net increase of these
winds combined with a threat for high based showers capable of
gusty outflow winds warrants watching for increased fire weather
concerns late week as dry surface conditions will remain in place.

&&

Slc watches/warnings/advisories...
Utah...none.
Wyoming...none.
