Area Forecast Discussion
National Weather Service Salt Lake City UT
859 AM MDT SUN MAY 29 2016

.SYNOPSIS...A low pressure system moving slowly east through the
desert southwest will serve to keep unsettled conditions across
portions of Utah through Monday. Strong high pressure aloft will
follow for the middle and latter portions of the upcoming week.


.DISCUSSION...Closed low moving across southern California today
combined with a trough moving across the Pacific Northwest will
create a deformation zone over mainly central and northern
portions of the CWA today. This deformation zone will increase
instability and with precipitable water between 0.50 to 0.70 of an
inch the prospect for scattered showers and thunderstorms looks
reasonable...especially over the central and northern mountains
this afternoon. However...this instability will need some
insolation to really get it going so have backed off on the threat
of showers and removed thunderstorms from the morning portion of
todays forecast.

Over southern portions of Utah the precipitable water is lower
and the instability is weaker so have lowered or removed pops for
some areas for this morning and some for the entire day. Cloud
cover was reduced for the morning.


.AVIATION...The winds at the SLC terminal will be southeast
through about 18-19Z before shifting to the northwest. There is a
30 percent chance that the winds could shift as early as 17Z.
Erratic wind gusts to 30 mph associated with showers and
thunderstorms are possible after about 1500.
