Area Forecast Discussion
National Weather Service Flagstaff AZ
848 PM MST Mon Dec 5 2016

.SYNOPSIS...Expect dry weather with near average temperatures
through Tuesday afternoon. A strong cold front is forecast to
move into Arizona from the north on Tuesday with a few light
showers late possible over the high terrain. Cold air behind the
front will linger for a few days with colder temperatures in the
forecast. A slight warming trend returns starting on Thursday.


.DISCUSSION...A zonal west to east upper level weather pattern
will keep Arizona mostly dry through the weekend. A dry cold front
will move into the state tonight from the north decreasing our
seasonably mild temperatures for a few days. Any shower activity
with this front continues to be on the light side with only trace
amounts possible over the high terrain.

The afternoon forecast grids look good. No evening updates.


.PREV DISCUSSION /354 PM MST/... A quick moving cold front
associated with a low pressure system will move across the region
Tuesday evening. This will cause an increase in winds from the
southwest during much of the day Tuesday before the frontal
passage. Some showers will be possible late tuesday with this
system, however the bulk of the precipitation appears to be well
north of Arizona, with only a few flakes possible over the higher
terrain near the Arizona Utah Border.

Colder temperatures are expected to follow behind the frontal
passage with the coolest night being wednesday or thursday.
Temperatures should begin to warm up gradually as mostly sunny
skies develop through the rest of the week and into the weekend.


.AVIATION...For the 12Z forecast...Expect VFR conditions over the
next 24 hours. Aviation discussion not updated for TAF amendments.
