Area Forecast Discussion
National Weather Service Salt Lake City UT
952 AM MDT MON JUL 25 2016

.SYNOPSIS...The flow is a little more southerly today and will
become light westerly on Tuesday with limited moisture across the
region. High pressure will expand west across the Great Basin
Wednesday through Thursday with a dry west to northwesterly flow
developing.

&&

.DISCUSSION...A weak trof sits along the west coast this morning
with a swly flow over Ut. A weak disturbance ejecting out of this
trof crossed nrn Ut this morning setting off a little weak
convection.

This feature looks to enhance the convection over ern Ut this aftn
while another weak disturbance lifts thru central Ut later today
generating convection along and east of the I-15 corridor from
about Provo south.

The deepest moisture is limited to the far southern CWA and there
is a small threat of heavy rain from cells in that area. Otherwise
storms today should be fairly high based with more wind than
rain.

The mid level ridge starts to recenter westward Tue with drier
westerlies starting to spread into west central and nwrn Ut.
Moisture is expected to linger over the mountains as well as
across the southern and eastern valleys with another round of
convection in these areas. This drying spreads across pretty much
the entire CWA on Wed.

Updated earlier to expand pops across nrn Ut for this morning and
increase cloud cover. Will update again to add isolated pops
farther west from about Provo south for this aftn.

&&

.AVIATION...Light and variable winds at the SLC terminal will
become prevailing northwesterly 18-19Z but light northerly winds
could develop as early as 17z. Any thunderstorms this afternoon
should stay well south of the airfield but there is a 10 percent
chance that storms will form in the southern Salt Lake valley and
outflow from these reaches the airfield.

&&

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