What happened

The episode as NWS AMA wrote it up.

A setup was in place for a persistent high wind event throughout the daytime hours. The Panhandles region were in a region of good surface divergence in the 300 hPa jet in-conjunction being on the lee side of a upper level trough in the Rockies. This set up under mostly clear skies was able to mix some of the strong winds aloft (700-500 hPa layer) down to the surface due to the steep height fields aloft. This allowed southwesterly down-slope winds to provide very breezy conditions with many counties in the combined Panhandles reaching High Wind criteria. A cold front came through the region that evening which tapered off the winds well below High Wind criteria.

What forecasters said that day

Area Forecast Discussion
National Weather Service Amarillo TX
533 AM CST Mon Mar 6 2017

.AVIATION...
Winds will be the main aviation concern for the terminals Today.
We will see strong west-southwest winds increase during the late
morning hours at each terminal before topping out in the 30 to
34kt range with gusts up to 45kt. Have issued an Airport Weather
Warning for KAMA due to strong gusts. These winds will persist
into the evening before diminishing as a cold front sweeps across
the Panhandles. Frontal timing is from 1Z at KGUY to near 3Z for
KAMA and KDHT. Winds will be fairly light behind the front and
will remain that way until the end of this forecast period.

One other aviation concern in the near term is the potential for
fog/stratus at KAMA around the 13Z hour. Satellite imagery shows
an area of low clouds/fog working northward. Have inserted a TEMPO
group for the low clouds but they should dissipate quickly as
mixing is anticipated to be starting around that same time.

.PREV DISCUSSION... /Issued 412 AM CST Mon Mar 6 2017/

DISCUSSION...
A busy short term as our highest impacts of the week are expected
to happen today with things quieting down for the rest of the
week. Critical to extremely critical Fire Weather Conditions
expected today with strong winds for a significant portion of the
Panhandles.

Today was a challenge as to whether or not we would go with a High
Wind Warning. Very strong 55-70kt 700mb jet moving overhead for
the northwest TX and the OK Panhandle, however this jet maximum is
expected to exit the area by noon, with weaker 700mb winds aloft
by 3pm. Right now not convinced enough that we will be able to mix
all the way to 700mb by noon, and even if we do that jet will
begin to weaken and the window for high gusts just looks too
narrow to go with a Warning. Will advise the day shift to monitor
the 9AM to 12PM wind gust trends and may need to upgrade
Advisories to Warnings if confidence increases.

The arrival of today's cold front is expected around mid afternoon
for the OK Panhandle with the passage through the south Texas
Panhandle by late evening. Once this front is through the winds
should be out of the northwest and in the 10 to 15 mph range,
ending the threat for the Wind Advisories. Blowing dust is
something that could be an issue today.

Tuesday onward...
The cold front that pushed through today will be short lived as
high pressure restrengthens to the west with 850mb temperatures
around 15C over the Panhandles Tuesday afternoon. This will still
make for mild temperatures in the 60s with maybe some isolated
lower 70s. This upward temperature trend will continue through at
least Friday, with temperatures on Friday looking to be in the
upper 70s to mid 80s. Although there are no POP's through this
point, GFS model attempts to bring a cut off low from the southern
Pacific just off the Baja Peninsula. Moist southerly flow ahead of
this low has suggested some slight chance showers/T-storms across
our extreme southeast counties. Confidence is not high enough to
include into the forecast. But we'll keep an eye on this to see
if anything else develops.

By Saturday there is a slight diverge in the model consensus. The
overall picture suggests a weak cold front lowering temperatures
into the 70s Panhandle wide. ECMWF lingers the cold air long
enough to have similar temperatures on Sunday, while GFS quickly
rebuilds the ridge and brings 850mb temperatures back up over 20C,
suggesting widespread temperatures in the 80s.

Weber

FIRE WEATHER...
Extremely critical Fire Weather day today.  Very windy and dry
conditions expected today across the Panhandles. Winds 20 to 40
mph with gusts up to 55 mph across the Panhandles and relative
humidities as low as 7 percent will promote critical, and in areas
of stronger winds, extremely critical Fire Weather conditions.
The dry air and winds have been talked about for awhile, so
confidence is high that today has the potential to be a
significant wildfire day. ERC values still approaching the 90th
percentile and widespread RFTI's of 6 and 7 with some isolated
8's across north central TX and the Central OK Panhandle. A cold
front is forecast to start moving across the area around 3pm from
the north to the south. Winds will shift out of the north, but
should only be in the 5 to 15 mph range.

Overall the rest of the forecast suggests just spotty elevated
Tuesday and Wednesday, with the possibility of widespread elevated
on Sunday.
