Area Forecast Discussion
National Weather Service Salt Lake City UT
346 AM MDT MON MAY 30 2016

.SYNOPSIS...A weakening cold front will push across central and
southern Utah today. Strong high pressure aloft will follow for
the middle and latter portions of the upcoming week.

&&

.SHORT TERM (through 06z Friday)...The forecast area remains
largely between two waves early this morning, as an upper low
spins over the lower CO river valley along the CA/AZ
border while a northern stream wave is noted crossing the
northern Rockies. This northern wave is skirting by northern UT
and has pushed a cold front through the Wasatch Front overnight,
with the trailing broken band of showers currently crossing the
central Wasatch Front. Have retained low pops for the morning
hours along and ahead of this band from roughly SL County
southward, and although this band will likely dissipate by mid
morning additional convection is expected to develop late this
morning through the afternoon from the Uintas south along the
spine of Utah.

A mid level ridge is forecast to begin building inland along the
Pacific Coast inland across the western Great Basin Tuesday, then
expand across the Intermountain Region for the middle to latter
portion of the week. Could see an isolated thunderstorm or two
over favored areas of the southern Mountains Tuesday, otherwise
this ridge will bring a significant warming and drying trend for
the remainder of the short term period. Salt Lake City will push
the 90 degree mark for the first time this year as early as
Thursday, with St George expected to reach triple digits for the
first time this season.

.LONG TERM (After 06z Friday)...Under a ridge of strong high
pressure, the ridge axis continues to create warming and drying with
temperatures nearing or just surpassing the 90 degree mark into the
weekend for many locations along the Wasatch Front as well as south-
central Utah.

By late weekend into early next week, long range forecast models are
in decent agreement with the development of another low pressure
trough swinging through central and southern California
northeastward into the Great Basin. Somewhat unsettled in nature
again, showers and thunderstorm potential for early in the week will
be present.

&&

.AVIATION...Expecting shower activity to come to an end after 12z at
KSLC terminal. Winds should become mostly calm under southerly
direction until 17z to 19z before turning northerly. Ceilings are
expected to remain above 8000 feet.

&&

.SLC Watches/Warnings/Advisories...
UT...None.
WY...None.
