Updated aviation discussion

.SHORT TERM...(Today through Saturday)
Issued at 219 AM MDT Fri Jun 23 2017

Cooler conditions, relatively speaking, will move into the area
today behind the cold front and trough that passed through the
area yesterday. High temperatures should be 5 to 7 degrees cooler
than on Thursday though that will still end up being 3 to 5
degrees warmer than normal. Dry conditions area expected with
little or no chance of convective development through Saturday.
Saturday will see the start of another gradual warming trend. The
bulk of the smoke from the Brian Head fire in southwest Utah will
travel south of the area, though some will keep filtering in
causing hazy conditions, especially near the Four Corners.

.LONG TERM...(Saturday night through Thursday)
Issued at 219 AM MDT Fri Jun 23 2017

The ridge will gradually build over the SW U.S. and Great Basin
through Tuesday and temperatures will slowly rise as well. Next
Monday night and Tuesday another weak trough will pass north of
the area causing the ridge to collapse to the south. This will
along a small amount of moisture, vertical shear and instability
into the area resulting in another round of isolated dry and
high-based thunderstorms. Zonal flow and dry conditions will
prevail Wed. and Thur.


.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1120 AM MDT Fri Jun 23 2017

VFR conditions will prevail over the next 24 hours as high
pressure remains over the southwestern US. Winds are expected to
remain 10 kts or under at all TAF sites with the exception of
KDRO and KGUC late this afternoon where they may see occasional
gusts to 20 or 25 kts. No clouds are expected today across eastern
Utah or western Colorado.
