Area Forecast Discussion
National Weather Service Salt Lake City UT
957 AM MDT THU MAY 26 2016

.SYNOPSIS...Several weak disturbances will cross the region
through the first part of next week.

&&

.DISCUSSION...The dominant feature this morning is a closed
upper low centered near 4 corners with some remnant convection
drifting swwd across ern and srn Ut. Models indicate the airmass
is fairly unstable today and the low level moisture in place will
generate terrain based convection starting shortly. the drift will
be towards the south so the threat for the nwrn valleys is minimal
today with the best activity over the mtns, and the central and
swrn valleys. This should die off this eve as we lose the solar
heating.

The next upper trof to impact the region is over swrn Canada this
morning and is forecast to drift east through Saturday with the
srn portion of this wave sweeping across nrn Ut Fri thru early
Sat. This should bring an increase in convection to the north
while the rest of the CWA looks to be a little less active due to
less instability. The north dries Sat aftn in the wake of this
wave while the south becomes more active under deformation between
the departing nrn wave and a new closed low that develops over
srn Ca.

For now have updated forecasts to lower pops across the north this
morning and raise them across the sw this aftn. Made some
adjustments to sky cover and winds as well. No additional updates
planned.

&&

.AVIATION...Light northerly or light and variable winds at the
SLC terminal this morning are expected to increase from the
northwest after 17Z and remain northwesterly into tonight.
Afternoon showers look to be isolated at best over the Salt Lake
valley with just a 20 percent chance that erratic outflow winds
will impact the terminal.

&&

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