Area Forecast Discussion
National Weather Service GRAND JUNCTION CO
255 AM MDT Sat Oct 21 2017

.SHORT TERM...(Today through Sunday)
Issued at 244 AM MDT Sat Oct 21 2017

Satellite and radar indicate some snowfall still occurring at this
hour but it looks to end fairly shortly. By daybreak, most
snowfall will likely end though a few showers will remain possible
over the higher terrain so are included in forecast. They can be
removed if precipitation ends sooner than thought. How much snow
did we get? Local webcams are indicating anywhere from 2 to 4
inches for the higher elevations of the northern and central
mountains so am sure a few spots got closer to 6 inches.
Mountainous areas south look to have received 1 to 2 inches.
Luckily, plenty of sunshine and relatively warm temperatures will
leave some wet pavement this morning and not much else to contend
with. Until then, expect some snowy/slushy roads especially over
Rabbit Ears and Vail Passes.

Now that the front has passed, northwesterly flow will allow cold
air to advect into the region. High temperatures will be much
cooler than seen yesterday but still about where they should be
for this time of year.

Sunday will bring plenty of sunshine and similar temperatures to
the region as seen today.

.LONG TERM...(Sunday through Friday)
Issued at 342 PM MDT Fri Oct 20 2017

Quiet start to the extended period with dry northwest flow in
place. Expect a gradual improvement in temperatures through
Wednesday with generally light valley winds and locally breezy
conditions over the mountains. Pattern shifts Thursday and Friday
with models in good agreement as we see another strong cold front
drop south across the Rockies. This will drive a round of low
valley rain and high valley/mountain snow back into the area. The
northern and central mountains will be favored for any heavier
precipitation although most locations should see a some
accumulating precipitation with cold low valley rains
anticipated. Temps drop off rather dramatically behind this second
front and could be 20 degrees below seasonal norms by the time we
move into the new weekend.


.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
Issued at 244 AM MDT Sat Oct 21 2017

MVFR conditions remain for KASE, KTEX, and KGUC at this hour while
VFR conditions are being reported at remaining TAF sites. Reported
snowfall should end shortly as ceilings lift for the above
mentioned TAF sites.  Now that the cold front has passed,
conditions will continue to improve for all TAF sites, and by 18Z
VFR will be the rule.
