Area forecast discussion 
National Weather Service Salt Lake City Utah
956 am MDT Wed Oct 26 2016

Synopsis...high pressure aloft will bring dry and warm conditions
to Utah through Thursday. A new fast moving weather disturbance
will impact Utah and southwest Wyoming Friday, followed by a
second system arriving late in the weekend.


Discussion...high pressure is building over the forecast area
this morning, resulting in dry and stable conditions with light
winds. Temperatures will be quite mild, with maxes running 10-15f
above seasonal norms across Utah and southwest Wyoming.

The ridge axis will shift east tomorrow, allowing southerly flow
to increase ahead of the next approaching storm system. This will
allow for a bit of additional warming. Winds should become quite
breezy on Friday just ahead of the storm system, particularly over
western and southern Utah. Ec/GFS indicate the system will track
over northern Utah as it weakens, but it has the potential to tap
into some tropical moisture, resulting in better coverage of

The storm system is on track to exit the area by early Saturday,
allowing high pressure to temporarily rebuild during the day.
However, the axis quickly shifts east again Saturday night/early
Sunday as another Pacific storm system approaches. Models in good
agreement that this system will also primarily impact northern and
central Utah, but will be a bit better organized compared to the
previous system.

No updates expected to the forecast this morning.


Aviation...VFR conditions at kslc terminal today under scattered
high level clouds. A stiff east/southeast flow will shift to the
south midday before the lake breeze comes in 22-23z. There is a
40% chance that it wont come in at all (light and variable winds),
and a 90% chance that if it does come in it will be light enough
to not even impact traffic management decisions.
