Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched 4 storm reports to this severe thunderstorm warning; the first came 1 minutes after it went out.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Amarillo Airport, TX (KAMA), launched 12:00Z, 6.6 hours before the alert went out and 130 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

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

NWS Amarillo, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Sep 17, 12:22 PM CDT, 1 hour 12 minutes earlier.

Area forecast discussion, Sep 17, 12:22 PM CDT, 1 hour 12 minutes before

Area Forecast Discussion...UPDATED
National Weather Service Amarillo TX
1222 PM CDT SAT SEP 17 2016

.AVIATION...
Have inserted a tempo group for thunderstorms at AMA for the first
couple of hours of the forecast. Otherwise, have left thunderstorms
out of AMA for the rest of the forecast as the new set of storms
should stay north of the site.

At DHT and GUY, have inserted a tempo group for thunderstorms from
the new activity that is expected to spread east southeast out of
northeast New Mexico later on this afternoon. Some of these storms
may be severe with damaging winds and large hail the main threats.
Skies should become VFR behind the storms for the rest of the
forecast. Winds will generally be at 10 knots or less outside of the
storms.

&&

.PREV DISCUSSION... /Issued 841 AM CDT SAT SEP 17 2016/

UPDATE...
Have expanded the dense fog advisory to include Carson and Gray
counties until 10 am. The fog is pretty shallow, so still think it
will start to break up by 10 am. A line of thunderstorms were
continuing to head east toward the western Texas Panhandle this
morning. Thinking is that these will tend to decrease in coverage and
intensity as they move into the western Texas Panhandle. These storms
are in association with the first more southern stream vort max
moving east across northeast New Mexico. Still think more showers and
thunderstorms will develop later on this afternoon near the Raton
Mesa in northeast New Mexico in association with a stronger vort max
moving southeast from Colorado. These showers and thunderstorms this
afternoon are expected to move east and southeast and expand as they
move across the Panhandles. Some of the storms this afternoon could
become severe with damaging winds and large hail the main threats.

PREV DISCUSSION... /Issued 631 AM CDT SAT SEP 17 2016/

AVIATION...
For the 12Z TAFS, LIFR to VLIFR conditions due to fog and low cigs
will persist at all terminal sites until around 15Z followed by
rapidly improving conditions thereafter. At this time, thunderstorm
potential appears greatest at KGUY and KDHT and have retained PROB30
groups at those two sites for later this afternoon and evening,
although confidence in this occurring is not especially high.

Andrade

PREV DISCUSSION... /Issued 421 AM CDT SAT SEP 17 2016/

DISCUSSION...
Water vapor imagery shows pos tilt upper low over southern Cal
beginning to slide south as it barely stays connected to main
northern stream flow. A strong jet entering the NW is now impinging
the northern flank of this low and will result in this feature
finally being cutoff from main flow. This means only one more day
of southwesterly flow aloft over the Panhandles as the main trough
axis pushes east resulting in more zonal or even northwest flow
late Saturday into Sunday. Weak impulses within the SW flow on
Saturday could help spark a few storms Saturday afternoon with a slightly
stronger impulse progged to cross the northern zones as the main
trough axis begins shifting eastward Saturday evening. This will
also help strengthen a surface boundary associated with the lee
side trough. Forecast soundings show adequate MLCAPE, surface
moisture and decent 0-6km bulk shear near 45-50kts with increasing
mid level flow through the day and veering profiles with a LLJ
during the evening. However, the best CAPE will be south of the
strongest upper level impulse, with potentially more MLCIN further
north where model sounding suggest a potential warm nose. Mid and
upper level moisture will certainly be limiting factors along the southern
and western TX Panhandle where updrafts will struggle to overcome
dry air entrainment. Still can't rule out a storms or two in the
south but chances appear to be better along our northern and
eastern zones closer to surface boundaries and where better upper
level dynamics and mid/upper moisture will be. CAMs are picking up
on possible line of storms moving through OK panhandle around 00z
and pushing southeast into the northern and eastern TX Panhandle
through the rest of the evening and overnight hours. At this
time...thinking there is some uncertainty mainly with the timing
of upper level impulse and how strong any cap may be. Any storm
that does develop will have potential to become severe. Steep low
and mid level lapse rates along with increasing LCL heights into
the evening will lead to more of a damaging wind threat. Hail up
to ping pong ball size certainly can't be ruled out given CAPE and
shear values expected...especially if storms can get going earlier
in the day.

850mb winds shift to the northwest Sunday morning bringing in much
drier air after the trough axis passes to our north and east. Upper
level flow will become zonal across the northern Plains and upper
level high pressure will form over the southern Plains. This will
lead to mostly dry conditions with a warming trend through mid-week.
Model then show a fairly substantial upper level trough move into
the western CONUS towards the end of the week. Will have to wait for
better model agreement before getting into the details...but expect
increasing precip chances and cooler temperatures once the ridge
breaks down.
