Area Forecast Discussion
National Weather Service Salt Lake City UT
1021 AM MDT Fri Jul 28 2017

.SYNOPSIS...Monsoonal moisture will remain in place across much of
the region today through the beginning of next week. A ridge will
bring a warming and drying trend starting mid week.

&&

.DISCUSSION...The mean ridge that has been a persistent feature
over the central/southern Rockies remains centered over nrn NM
this morning with a light swly flow over our CWA. A well defined
short wave in this flow is lifting into central and nrn UT at this
time with a band of showers and isolated tstms extending roughly
from Wendover to Price.

This wave will continue to lift slowly thru the nrn CWA thru the
rest of the morning and into the afternoon but it may take most of
the day before it exits the CWA.

Deep moisture persists over the south with isolated showers near
the srn end of Lake Powell and new ones forming near Hanksville.
Expect mainly terrain based convection will dominate the srn and
ern CWA this aftn with some of these storms drifting out over the
valleys. The southwest should stay on the dry side in the wake of
the short wave.

The north should dry out overnight behind this short wave with a
less active day expected tomorrow. The south and southeast should
have another round of diurnal convection.

Updated earlier to expand pops across all of the north for the
rest of the morning and kept a mention of isolated convection in
for this aftn across the nw as the short wave will be slower to
move out.

No additional updates planned.

&&

.AVIATION...Southerly winds at the SLC terminal will be gusty at
times as showers cross the terminal until about 19-20z. Winds
should shift to northwest after that. Any cigs will remain above
7000 ft.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...None.
WY...None.
