.SYNOPSIS...Moisture will be drawn north into southwest Utah this
evening then spread across the remainder of the area through
Monday. Drying from the west starts Monday night and continues on
Tuesday with dry and warm weather returning for the middle of the


.DISCUSSION...Deep layer swly flow is over the ern Great Basin
this eve downstream from a deep trof in the ern Pac with moisture
beginning to spread into the CWA from the southwest. Radar returns
show a few light showers spreading up the west side of the state
but these are mostly aloft with just a few sprinkles reaching the

Expect showers to slowly increase across the wrn CWA overnight
then fill in across the west Mon morning as a short wave lifts out
of srn CA into the Great Basin. A second weak wave lifts newd Mon
aftn spreading the precip into ern UT. So expect widespread precip
across the CWA tomorrow. There is a potential for some embedded
convection and a few pockets of heavy rain but the flood threat
looks low.

This is a very warm system and snow levels look to stay at or
above 10000 ft.

This second wave moves east Tue with showers tapering off. The
offshore trof deepens Tue night with the downstream ridge
amplifying over the Great Basin for Wed and Thu returning the
area to a warm dry pattern.

Updated earlier to significantly lower pops across all but the
far swrn CWA overnight as it became clear that the onset of
widespread precip across the rest of the area would hold off until
morning. No additional updates planned.


.AVIATION...Southerly winds at the KSLC terminal will become
gusty around 14-15z. Light passing showers could bring gusty
erratic outflow winds as early as about 05-06z. VFR conditions
will prevail overnight. CIGS should stay above 7000 ft thru the
night but will likely fall to around 6000 ft after about 15z.
