Area Forecast Discussion
National Weather Service Salt Lake City UT
403 PM MDT Fri Jun 7 2019
.SYNOPSIS...An unseasonably cold upper level trough will move
east across the northern Rockies tonight through Saturday. The
associated cold front will sweep southeast across the state late
this afternoon through tonight. Much colder temperatures this
weekend will be followed by a warming trend early next week.
&&
.SHORT TERM...A cold frontal boundary has been stalled across the
NW portion of Utah through the day. Gradual pressure falls have
been analyzed across western Utah with a surface low analyzed
over Tooele County. A nicely organized upper level trough will
slide south this evening, further deepening the surface low and
also allowing the front to begin its progression south through
Utah and southwest Wyoming. The tightening pressure gradient,
surface pressure falls, and increased flow aloft is allowing the
area ahead of the front to receive strong gusty winds out of the
southwest up to advisory level across the western zones as well as
the Salt Lake/Utah Valleys. These winds are projected to continue
through the afternoon into the evening.
Scattered showers and isolated thunderstorms have developed ahead
of the cold push currently analyzed over the Raft River/Goose
Creek Mountains of far NW Utah. There is marginal instability to
work with with CAPE values between 500-1000 J/kg and moderate
effective bulk shear values between 40-50 kts. This at least
provides marginal potential for an isolated strong to severe
thunderstorm across Box Elder/northern Tooele county this evening.
The severe potential is low, since storm relative upper level
shear vectors are generally aligned parallel to the boundary and
high LCLs supporting merging of the cold pools with relative ease.
The thunderstorm threat should subside with the loss of heating,
allowing scattered showers to continue across the higher terrain
areas of northern Utah this evening and tonight.
As previously mentioned, the cold front will move through the area
this evening and tonight once the cold air aloft and on the
surface catches up to the boundary. This cold push will allow the
winds to sharply shift out of the northwest. A continued
tightening pressure gradient combined with increased downward
momentum transfer to the surface will allow advisory level wind
speeds to continue until around midnight. An extension of this
advisory may be warranted into the early morning hours as the
pressure gradient ceases to loosen until tomorrow afternoon. There
is also potential for increased winds across Utah's Dixie
tomorrow evening/night. An advisory for that area is not
warranted ATTM, however it will be investigated over the next 24
hours or so.
The cold front will allow for colder temps with dry air to prevail
area wide through the weekend. Ridging with much drier conditions
are expected to prevail Monday into Tuesday.
.LONG TERM (After 00Z Tuesday)...A Pacific high will strengthen and
make its way east through midweek, with the axis moving over Utah
and southwest Wyoming on Wednesday. This will result in drying
conditions with a warming trend in temperatures. Maxes are expected
to run at least 5F above seasonal normals areawide for Wednesday
into Thursday.
For the latter part of the upcoming week, the ridge is expected to
weaken and shift east as a storm system approaches from the Pacific
Northwest. The GFS solution remains faster with this system compared
to the EC, moving it into the forecast area Thursday night into
early Friday as opposed to Friday afternoon in the EC solution.
Regardless, the trough looks relatively weak, but should bring
temperatures back to around seasonal normals and increase the threat
of diurnal convection, at least over the higher terrain.
&&
.AVIATION...Northwest wind should increase and become gusty near
and behind the front 01Z to 04Z at the KSLC terminal. Wind should
relax but remain northwest through the rest of the TAF period.
Scattered showers possible near and just behind the front 23Z to
04Z.
&&
.FIRE WEATHER...Red Flag Warning in Effect through 9 PM MDT this
evening for Zone 497 below 4500 feet due to gusty winds and low
RH.
ERC values remain below the 50th percentile, but are rising
across the state as drying slowly takes over.
Expect breezy conditions with low RH expected for most valleys
today as a cold front stalls across northwest Utah. The cold front
will cross the state from northwest to southeast tonight,
bringing cooler temperatures to the region through the weekend.
Isolated to scattered showers and thunderstorms are expected for
portions of northern and eastern Utah this afternoon.
A warming and drying trend is forecast beginning Sunday and
extending through at least the middle of next week.

This front will generate strong and quite gusty southerly winds across the western valleys this afternoon through early this evening. Behind the front gusty northwest will exist for several hours with the strongest winds across the Salt Flats and through portions of northern Utah county. With much warmer temperatures, snowmelt will accelerate at high elevations. Waterways remain running high, cold and swift. Exercise caution near waterways, and keep a close eye on children and pets. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Much colder temperatures will follow the cold front south through Utah Saturday. High temperatures Saturday will run between 10 and 20 degrees colder than the highs from Friday. Sunday will see warmer temperatures, though readings will remain below normal across the outlook area. Clear skies, light winds and low humidities will allow temperatures to drop into the 30s across some of the higher northern valleys Sunday morning. A few areas could see below freezing temperatures late Saturday night through early Sunday morning. .SPOTTER INFORMATION STATEMENT...
