Area Forecast Discussion
National Weather Service Flagstaff AZ
1021 PM MST Sat Apr 19 2025

.SYNOPSIS...The low pressure system that brought rain and snow to
the region over the past two days has moved east of the state this
evening. Dry and much warmer weather is on the way over the coming
week.

&&

.UPDATE...Skies have cleared this evening as the storm system that
brought rain and snow to the region Friday and in eastern Arizona
today has moved east. After a cold night tonight, a dry and much
warmer week is on the way. No forecast updates are needed this
evening.

&&

.PREV DISCUSSION /428 PM MST/...The center of our most recent low
pressure system was located over west-central New Mexico at mid
afternoon, rapidly heading eastward. Moisture wrapping around the
low was continuing to produce a few snow showers over far eastern
Arizona along the New Mexico border. All indications are that the
remaining precipitation will come to an end by the early evening.

For tonight...Clear skies along with light and variable winds are
in store as the low exits the state. Drier air moving in from the
northwest will usher in low temperatures 5 to 15 degrees below
normal, especially at any higher elevations that remain snow
covered.

Starting Sunday and through the workweek...A dry west to northwest
flow aloft will set up over the southwest United States. As a
result, a milder air mass will move over Arizona through the week
with warming daytime temperatures. Sunday high temperatures will
approach near average for this time of year with temperatures then
climbing to 5 to 10 degrees above average by Wednesday.
Otherwise, generally clear skies are forecast with west to
southwest afternoon breezes at 5 to 15 mph each day. There could
be some strengthening of breezes come Thursday and Friday as a
trough approaches the west coast strengthening surface pressure
gradients across Arizona.

.AVIATION...Sunday 20/06Z through Monday 21/06Z...Expect VFR
conditions and light winds.

OUTLOOK...Monday 21/06Z through Wednesday 23/06Z...Expect VFR

.FIRE WEATHER...Today through Sunday...Showers continuing through
this afternoon east of a Payson to Page line, mostly diminishing by
tonight. Northwest through northeast winds at 10-15 mph gusting to
25 mph today, then becoming light and variable on Sunday.

Monday through Wednesday...Dry and warm. Southwest winds at 10-15
mph each afternoon, with minimum RH 10-20%
