1156 PM CDT Fri Oct 21 2016

.SHORT TERM...(tonight through Monday)
Issued at 230 PM CDT Fri Oct 21 2016

Dry and rather mild weather should prevail through the short term
as broad area of high pressure at the surface and aloft dominates
the pattern in advance of a strong upper trough approaching the
West Coast. Warm days and seasonably cool nights are expected over
the weekend with minimal cloud cover.

.LONG TERM...(Monday night through Friday)
Issued at 230 PM CDT Fri Oct 21 2016

Initial short wave energy associated with the west coast trough
begins to spread into the region late Monday night and Tuesday
with rain chances increasing during the day on Tuesday and into
Tuesday night as trough amplifies while moving through the region.
The trough moves east of the area on Wednesday with ridging
returning to the region behind the system for Thursday. Strong
system moving across southern Canada on Friday will bring a brief
cool down on Friday but at this time no additional rain expected.


.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1156 PM CDT Fri Oct 21 2016

VFR conditions will prevail through the TAF period. No appreciable
cloud cover is expected, except for high level cirrus streaming
over top of H5 ridge axis.  Surface pressure gradient increases
during the afternoon Saturday due to lee side troughing; however,
wind speeds not expected to exceed 12kts. There is some
indications of LLWS developing after 23/03 UTC as LLJ strengthens
above decoupled boundary layer, but will wait a couple TAF cycles
to add.
