.SHORT TERM...(Tonight through Friday night)
Issued at 342 PM MDT Thu Oct 12 2017

Another great fall day today with temperatures running several
degrees above normal but you won`t hear many complaints from this
office. As expected, the upper level jet and tightening pressure
gradient are causing some gusty winds with gusts varying from 25
to about 35 mph. These winds will die down over the next few hours
giving way to generally clear skies overnight. Tomorrow, an almost
exact duplicate of today so get out there and get a jump on the
weekend if possible!

.LONG TERM...(Saturday through Thursday)
Issued at 342 PM MDT Thu Oct 12 2017

The jet stream will start diving down from the northwest Friday
night into Saturday and will cause an upper level trough to
deepen somewhat and shift eastward. Model runs remain in good
agreement that the surface cold front will stay mostly dry as it
moves across the Wyoming and Colorado border Saturday. A few snow
showers will fall over the Uintahs, Flat Tops, and eastern
Uintahs but accumulations will be minimal. The noticeable
difference will be high temperatures for both Saturday and Sunday
as northerly flow ushers in colder air from the north.
Temperatures will drop a few degrees below normal for both days
but this will be short lived. By Monday, flow returns to
southwesterly allowing warmer temperatures to move in. The rest of
the work week looks dry as temperatures hover right around
normal. Another nice week in store.

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1157 PM MDT Thu Oct 12 2017

VFR conditions will prevail over the next 24 hours as a dry
southwest flow remains over the region. Winds will become breezy
Friday afternoon with gusts in the 20s and 30s at most TAF sites.
The stronger upper level winds may cause some mechanical
turbulence over the ridges with some low level wind shear in the
overnight period as valley winds decouple.
