914 AM MST Sat Apr 28 2018

.SYNOPSIS...There are slight chances for high based thunderstorms
producing gusty outflow winds today along and northeast of the
Mogollon Rim. Southwest winds will also develop, with gusts to 40
mph across Coconino County this afternoon. Cooler, dry, and breezy
conditions are expected Sunday through Monday. Much colder and
unsettled conditions return starting Tuesday.

&&

.UPDATE...
Water vapor loop this morning shows much drier air moving into
western AZ with gravity waves indicating southwest flow already
over Mohave county. The mid level moisture field that covered much
of the northland yesterday is now across Navajo and Apache
counties, with scattered light radar echoes seen across the
southern half of Apache county.

We have two sources of wind to watch today. Southwesterly
gradient winds due to a trough of low pressure over the Pacific
northwest will bring gusts to 40 mph to Coconino county. The
second is outflow winds from isolated high based showers/Tstorms
across areas east of along from Page- Flagstaff-Payson through
this evening. Yesterday, outflow gusts of 53 mph were measured at
the Grand Canyon Airport, and 49 mph at Kykotsmovi. Downdraft cape
values are slight higher today v yesterday across northeast AZ
indicating the potential for faster outflow winds.

The short term forecast is in good shape with no updates.

&&

.PREV DISCUSSION /428 AM MST/... We are expecting more chances for
high-based showers and isolated embedded thunderstorms again
today, though now generally confined to eastern Arizona. Daytime
temperatures will remain above normal through the weekend, though
tightening pressure gradients will lead to increasingly gusty
southwest winds. A Red Flag Warning for today and a Fire Weather
Watch for Sunday remain in effect for portions of the Northland to
address the concerns for extreme fire behavior. Dry weather
returns for Sunday through Monday night, though gusty daytime
winds will persist for Monday.

By Tuesday through Thursday of next week, low pressure will bring
much cooler temperatures and periods of rain and high elevation
snow showers, along with the additional potential for a few
thunderstorms. Unsettled conditions may linger through the end of
next week, under gradually warming daytime temperatures.

&&

.AVIATION...For the 18Z package...VFR conditions will prevail over
next 24 hours. Southwest winds 15-25 kts gusting 30-35 kts with the
strongest winds across Coconino and Yavapai Counties. Isolated high-
based showers/thunderstorms likely mainly across Navajo and Apache
Counties through 03z Sun. Aviation discussion not updated for TAF
amendments.

&&

.FIRE WEATHER...Expect isolated to scattered dry high-based showers
and thunderstorms into Saturday evening, mainly across Navajo and
Apache counties with very little precipitation. Gusty southwest
winds will create critical fire weather conditions across western
Coconino and Yavapai counties Saturday, expanding to cover most of
northern Arizona Sunday.

Monday through Wednesday...Breezy southwest winds persist on Monday
with a storm system bringing much cooler and wetter weather to the
region Tuesday and Wednesday.

&&

.FGZ WATCHES/WARNINGS/ADVISORIES...Fire Weather Watch from Sunday morning
through Sunday evening FOR AZZ104>117-137>140.

Red Flag Warning until 7 PM MST this evening FOR AZZ104-106>108.
