Area Forecast Discussion
National Weather Service Flagstaff AZ
340 PM MST Tue Jan 24 2017

.SYNOPSIS...Scattered snow showers will persist through this
evening, especially over higher terrain and along the Mogollon
Rim. Some snow showers will produce brief periods of heavy
snow causing near zero visibility at times. Dry and very cold
conditions will then develop for this remainder of this week.


.DISCUSSION...So far today, the most numerous and heaviest snow
showers occurred along the Mogollon Rim, roughly from Flagstaff
southeastward. Many of the these showers produced periods of
heavy snowfall. For example, Munds Park saw several rounds of
heavy snow showers leading to between 4 to 5 inches of new snow
there. These snow showers are expected to continue through the
evening hours, with the best shot at additional snow accumulations
continuing to be along the Mogollon Rim from Flagstaff

From Wednesday through Friday, northern Arizona is forecast to
remain under the influence of a very cold and dry airmass. As a
result, dry weather with well below normal temperatures are
forecast through the remainder of the work week. Much of the High
Country is forecast to see overnight lows dipping into the single
digit to below zero temperature range. On Friday, a shortwave
trough is forecast to cross the region leading to breezy northeast
winds, but conditions looks to be too dry for precipitation.

Over the weekend, heights begin to rise as an upper level ridge
builds across the West Coast. This is expected to lead to a
gradual warming trend through at least early next week.


.AVIATION...For the 00Z package...Primarily MVFR conditions will
continue along the Mogollon Rim near KGCN-KFLG-KSEZ-KSOW this
evening. Scattered snow bands could produce brief periods of
IFR/LIFR condtions near KFLG-KSEZ through 03z. KPRC could see banded
precip between the 01z-05z Wed. time period. VFR conditions should
prevail over northern Arizona after 06z Wednesday through the
remainder of the TAF period.

KGCN is experiencing comms issues so will keep AMD NOT SKED in its
TAF until further notice. Aviation discussion not updated for TAF
