What forecasters said that day

The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Flagstaff, AZ wrote its last area forecast discussion before this winter storm warning went out at Feb 26, 9:47 AM MST, 4 hours 26 minutes earlier.

Area forecast discussion, Feb 26, 9:47 AM MST, 4 hours 26 minutes before
Area Forecast Discussion
National Weather Service Flagstaff AZ
947 AM MST Sun Feb 26 2017

.SYNOPSIS... An unsettled pattern will continue through the first
half of the week, with breezy and cool conditions along with a
good chance for rain and snow showers. Dry weather and a warming
trend is then forecast Wednesday through the end of the week.

&&

.UPDATE...Current regional radar imagery depicts elevated mid-
level precipitation spreading across northern Arizona primarily
along and south of I-40. This is in response to a weak trough over
western Arizona forecast to pivot west to east across the state
today.

The 12z Flagstaff sounding indicates a dry layer up to 600mb, or
6500 feet above ground level. As the mid-level precipitation falls
into the drier low levels, cloud bases should also drop through
the day. Very light precipitation could reach the surface later
today, with snow levels between 5000-5500 feet. Accumulations
should be light.

Overnight, a strong mid-level inversion is forecast to set up
around 700mb near the San Francisco peaks. Strong southwesterly
wind gusts around 40 knots will likely develop downwind of the
peaks, primarily across Doney Park in the 2am-8am Monday period.
Trash/recycling bins could be thrashed about if not secured
properly.

The focus then shifts to the Monday-Tuesday winter system. Will
wait until the latest ECMWF becomes available to make adjustments
to the precipitation forecast. Stay tuned.

&&

.PREV DISCUSSION /347 AM MST/... The first of two troughs of low
pressure is moving through the region today with cold
temperatures and showers across the region. Temperatures are
expected to be at their lowest values during this first system.
Snow levels this morning will be around 4500 feet allowing for
early shower activity to fall as snow with some light
accumulations possible. Snowfall amounts from this quick moving
shortwave should generally range from 0.5 to 1 inch. This is due
to the quick moving and dry nature of this first wave.

A brief quiet period will develop this evening and last overnight
before the next trough begins to affect the area.

By Monday afternoon moisture ahead of the next trough will begin
to stream into the area on from the Pacific coast off the Baja
penisula. While confidence over available liquid precipitation
has risen due to an continued increase in the amount of
atmospheric moisture over the past 24 hours, confidence in
snowfall amounts remains more conservative.

The main concern is the warm nature of the moisture plume
associated with this second system. Models continue to push
towards a warming trend through the second event. If this solution
comes to pass snow levels could initially start out cold enough
for snowfall at lower elevations before transitioning to rainfall
as the storm progresses across Northern Arizona. Model Soundings
suggest that some of these warmer solutions are overplaying the
potential for this transition, however there is not a lot of room
for error in the temperature profile across Northern Arizona.
Areas that are currently forecast to experience a significant
winter event may have a warmer and wetter reality. Have kept with
a cooler solution for the time being. Moderate confidence in a
winter weather event has necessitated the need for a Winter Storm
Watch for locations above 6000 feet along the Mogollon Rim from
late Monday Morning through Tuesday Afternoon. Interested parties
should continue to pay close attention to the forecast due to the
amount of change that could occur from relatively small changes in
the forecast solutions.

As previously mentioned confidence is increasing in a significant
moisture event that could create some impacts across the lower
terrain especially in Yavapai and Northern Gila Counties. Have
held off on issuing any hydrologic highlights at this time,
however some may become necessary as the event nears.

From Wednesday onward drying and warming conditions are expected
across the region as a ridge of high pressure builds into the
area. This should continue through rest of the week and into the
weekend with temperatures climbing back above seasonal averages.

&&

.AVIATION...For the 18Z package...Widespread ceilings 5000-7000
above ground level for the next 24 hours. An upper level disturbance
will move from west to east across northern Arizona today, with
areas of MVFR ceilings and showers across the high terrain of
northern Arizona. Showers to move out of the state after 00Z but
areas of MVFR ceilings will remain. Surface winds southwest 5-20
knots. Aviation discussion not updated for TAF amendments.

.Day One...Today and Tonight

A fast moving upper level disturbance will bring a quick shot of
showers to northern Arizona today. Snow levels will be in the
4500 to 5500 foot range with snow accumulations generally less
than one half an inch. Temperatures will continue to be below
normal.

.DAYS TWO THROUGH SEVEN...Monday through Friday

A winter storm watch is in effect for areas above 6000 feet along
the Mogollon Rim and White Mountains from 11 am Monday through
5 pm Tuesday. The current snowfall forecast has storm totals from
8-12 inches across the populated areas of the Mogollon Rim and
White Mountains. 4 to 8 inches of snow are possible across the
Kaibab Plateau and Chuska Mountains. For now it appears that
little to no snow accumulation is expected for Prescott or Payson.

Liquid precipitation totals for Monday and Tuesday are forecast
to range from 0.75 inch to one inch across areas south of I-40
primarily over Yavapai and Gila counties, and along the Mogollon
Rim. These amounts will likely cause rises in creeks and streams
in Yavapai and Gila counties. No major flooding impacts are
expected at this time.

Clearing to return Tuesday night with fair and warmer weather
starting Wednesday.

.SPOTTER INFORMATION STATEMENT...

Weather spotters are encouraged to report significant weather
