Area Forecast Discussion
National Weather Service Salt Lake City UT
1017 AM MDT Fri Apr 21 2017

.SYNOPSIS...A cool northwest flow today will be replaced by high
pressure on Saturday bringing a warming trend. An active weather pattern
is expected for next week, as a series of storm systems are
forecast to pass through the region.


.DISCUSSION...The lake induced showers have all but dissipated
southeast of the GSL so have reduced the chance to slight chance
for the remainder of the morning. The sky cover will improve along
the Wasatch Front by this afternoon to mostly sunny or at least
partly cloudy as the temperatures aloft warm and the air mass
stabilizes and drys.

Have also improved the sky cover for the western Uinta Basin,
Castle Country and the central mountains as clear skies already
prevail there and should the remainder of the day.

Some local breezes of 15-25 mph are expected in Castle Country and
the western Uinta Basin as the favorable NW-SE surface gradient
combines with a somewhat stout northwest 700 mb flow of 15-20

Temperatures across the northern two-thirds of the CWA will be
5-10 degrees below average today despite plenty of late April
sunshine this afternoon. The southern third of the CWA will see
temperatures near or just slightly below normal today.


.AVIATION...Light and variable winds will continue at the SLC
terminal through at least 17Z, before northwesterly winds increase
above 6 knots between 17Z and 20Z. Ceilings should rise above 7000
feet around 17-19Z, as lake effect showers continue to diminish.
