What forecasters said that day

The local office's own words before this high wind 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 high wind warning went out at Mar 28, 9:30 PM MST, 5 hours 48 minutes earlier.

Area forecast discussion, Mar 28, 9:30 PM MST, 5 hours 48 minutes before
Area Forecast Discussion
National Weather Service Flagstaff AZ
930 PM MST Tue Mar 28 2023

.SYNOPSIS...Warn and windy conditions are expected on Wednesday
ahead of storm system that is expected to bring rain and high
elevation snow to the region on Thursday. Dry conditions with
warming temperatures then return for Friday into the weekend.

&&

.UPDATE...Latest guidance this evening has come in with a bit
better dynamics for the upcoming system, with the GFS the most
bullish and coming in quite a bit wetter than the other guidance.
Both QPF and PoPs were adjusted for the Wednesday night-Thursday
night timeframe to keep within the envelope of the latest guidance
a bit better. Since QPF increased, snow amounts increased a tad
over the higher terrain with this evenings update. However, given
the gusty winds and marginal temperatures during the daytime on
Thursday, snow ratios (and consequently amounts) will likely not
be very high. The current forecast calls for around 2-4 inches in
the upslope areas over the Kaibab Plateau and the Mogollon Rim and
a Trace-2" elsewhere above 6000 feet. The most intense rain and
snow looks to move into the region Thursday morning, as strong
frontogenetic forcing moves into region. Outside of that
timeframe, less intense isolated to scattered rain and snow
showers will be possible.

While accumulations are not forecast to be significant, hazardous
driving conditions will be possible due to poor visibility and
snow covered roads. Gusty winds may also further hamper travel
with patchy blowing and drifting snow.

Beyond the Wednesday/Thursday timeframe, the afternoon forecast
package remains on track and unchanged. Previous discussion
continues below.

&&

.PREV DISCUSSION /231 PM MST/...After a period of tranquil
weather, our next upper level low, currently across the Pacific
NW, is forecast to dive southward along the California coastline
through the day on Wednesday. Thereafter, the multi-model grand
ensemble projects that this low will transition more into an open
wave as it slides through the Four Corners region. Wednesday and
Thursday offer the best opportunities for precipitation and wind
gusts in excess of 30 mph.

On Wednesday, the low level height gradient is expected to
tighten resulting in a conveyor of 40 to 45 knot flow aloft
across the western Coconino and Kaibab Plateaus as well as the
higher terrain of Yavapai County. Around 80-90% of NBM v4.1
membership advertises peak wind gusts in excess of 40 mph across
these aforementioned areas on Wednesday and as a result a Wind
Advisory has been hoisted for these regions. Other areas that may
approach 40 mph wind gusts include locales downwind of the
Mogollon Rim and across the Black Mesa. At this juncture,
probabilities are lower for areas along and east of the U.S. HWY
89/I-17 corridors on Wednesday, but we'll need to evaluate the
next suite of NWP this evening and into early tomorrow morning.

The active weather pattern will continue late in the day on
Wednesday and into the pre-dawn hours on Thursday, as the first
wave of precipitation is forecast to develop near the CA/AZ/NV
border. The tail end of the 12 UTC HREF guidance suggests that
initial bands of precipitation will slide into the western
Coconino and Kaibab Plateaus with the upslope machine cranking up
along the central and eastern Mogollon Rim. Enhanced surface flow
(40 to 50+ mph wind gusts) downwind of the higher terrain
features are common in this pattern and we'll need to monitor for
any wind headlines Wednesday night into Thursday along the
Mogollon Rim.

Late Wednesday through sunrise Thursday, the greatest
precipitation chances (20%-60%)reside along the central Mogollon
Rim/SF Peaks and areas west of US HWY 89. 1-2" snowfall amounts
forecast largely above 6500' elevation during this period.
Through the day on Thursday, the mid/low level height gradient
intensifies initially as the main upper trough approaches. With
intermittent periods of moderate snow, the Thursday morning
commute may be slick and hazardous, especially across areas above
6500' elevation. The height gradient will tighten most noticeably
along the eastern Mogollon Rim and White Mountains area after
sunrise. With the percentage of NBM membership with wind gusts of
60 mph or greater around 90%...a High Wind Watch has been issued
for the White Mountains area. Additional wind headlines may be
required for the rest of the High Country, but at this time,
there's still a little too difficult to discern which areas may
experience the strongest winds. Regardless, individuals across the
area should secure any loose outdoor articles and be prepared for
difficult driving conditions (due to the combo of wind and
precipitation). With 50 to 55 mph winds some impacts to power
infrastructure cannot be discounted.

Thursday afternoon and into Friday evening offered the opportunity
to make the most noteworthy changes to the PoP/QPF fields from the
NBM. While flow aloft becomes a bit more westerly, mid-level
moistening in both 2D plots and forecast soundings takes place as
120 meter height falls overspread the area. Forecast soundings
also reveal the presence of 100-300 J/kg of CAPE, most noticeably
north of I-40. With the cooler pocket of air aloft, mid-level
moistening, and instability, there will be a thunderstorm risk.
Brief bouts of intense snowfall rates (1-2"/hr) cannot be
discounted and it is within these deeper showers and storms that
travel will become extremely dangerous due to visibility under 1
mile, winds in excess of 30 mph, and slick roadways. The most
likely time frame for these bouts of showers and thunderstorms
will be Thursday afternoon and into Thursday evening and the
preferred area will generally be along and north of I-40. As a
result, the Thursday afternoon/evening commute may be challenging
due to these showers and isolated storms.

Storm total snow amounts (Wednesday Evening - Friday Morning) for
the area actually reside within the 50th to 75th percentile of
the NBM (on average 2 to 4 inches for locations largely above
6500'). Worst case scenario (NBM 90th percentile) would result in
storm total snowfall closer to 3 to 6 inches across the High
Country. Should showers and thunderstorms become more widespread
than currently anticipated, the 90th percentile snow accumulations
may offer a more reasonable forecast.

Precipitation is forecast to exit stage right (to the east in our
case) by midnight Friday. Wind gusts will abate below 40 mph with
largely uneventful weather this weekend and into next week. The
coldest night appears to be Friday morning with temperatures in
the teens and twenties across the mountains to thirties and 40s
elsewhere. The upper air pattern remains largely zonal into next
week, but limited moisture precludes mentioning any precipitation
in the forecast. Technically, the greatest PoPs are around 10%
along the UT/AZ/CO border Monday and into Tuesday, but we'll
examine the need for higher precipitation chances with subsequent
forecasts.

.AVIATION...For the 06Z TAF package...VFR conditions will continue
through the TAF period. South to southwest winds 5 to 15 knots,
increasing after 17Z to 15 to 25 knots with gusts up to 35 knots.
Aviation discussion not updated for TAF amendments.

&&

southwest winds increasing to 15 to 25 mph and gusting as high as 35
to 45 mph. Winds remain gusty Wednesday night, with rain and snow
moving in west to east late at night. Strong southwest winds are in
the forecast for Thursday, along with a good chance of rain and
snow.

Friday through Sunday...Dry conditions return on Friday through
Sunday, with a warming trend. Decreasing winds turn westerly on
