The episode as NWS AMA wrote it up.
A dryline sharpened during the afternoon and significant moisture surged northwestward. This set the stage for supercell thunderstorms capable of very large hail. Low level shear was most favorable for tornadoes in Kanasas, although one brief tornado did occur in the northern Texas Panhandle. Storms were LP in nature and the largest hail of the day was 3.5 inches in diameter.

.Mesoscale Update...
19z KAMA sounding shows similar low level moisture depth as the 12z
sounding and mixing now up to just above the top of this layer and
we initially started to mix out. Hot/dry air to the west of the
dryline and attendant surface pressure falls have caused winds ahead
of the dryline to turn more southeasterly and confluence along the
dryline to increase. Sharpening dryline is setting up from just east
of Liberal to near Borger to near Amarillo. Deepening cumulus field
has formed along and behind the dryline with glaciation noted in
satellite and weak echos have recently shown up on radar from near
Fritch to just west of Tulia.
There has been little change in earlier thinking other than minor
adjustments to the position of the dryline. Also, we have a better
handle on residual boundaries across the area. The most prominent is
an outflow from overnight convection which now extends from near
Dodge City southeastward across northeast Beaver County to near
Gage. East of this (including a small portion of Beaver County) low
level shear is enhanced with slightly backed winds. This boundary is
nearly stationary. Other mesoscale features include bands of
northwest to southeast oriented enhanced cu, probably associated
with areas of enhanced low level moisture. One is oriented
downstream of developing convection near Borger. We will need to
monitor this closely for possible enhancement of low level shear in
case these enhanced cu fields are more baroclinic than they
currently appear.
Another concern is retreat of the dryline later this evening and the
potential to involve a larger portion of the central Panhandle.
Similar to last night, cool outflow from convection if it becomes
extensive enough, will augment/accelerate the retreating dryline and
may be enough for at least marginal severe threat further west
including the city of Amarillo.

Skies should remain VFR through this forecast. Thunderstorms will be
possible near the AMA TAF site this afternoon, but at this point it
looks like they will be just east of AMA. Gusty southerly winds will
decrease tonight after sunset. Winds will then veer some toward
sunrise.

Mesoscale Update...
.Severe weather expected today across the eastern Panhandles...
* Synoptic Overview: Water Vapor loop shows a complex pattern in the
western United States, with a broad trough and embedded shortwaves.
One fairly potent shortwave trough is now located in southern
Nevada and is slowly moving east. Mid-level momentum will
overspread much of New Mexico through the day and spread into the
Texas Panhandle by early evening. Subtle mid-level height falls are
expected to begin across the region by afternoon and provide more
large scale ascent, albeit still quite weak, than was seen
yesterday.
* Mesoscale: 15z hand surface analysis shows that low level flow has
veered across much of the Texas and Oklahoma Panhandles with the
exception being in the Southeast Texas Panhandle. A moisture
discontinuity is present along this confluence zone which extends
from near Lipscomb to Borger to Palo Duro Canyon. This is the
beginning of what is expected to be a sharpening dryline later this
afternoon. Latest surface observation at Amarillo ASOS has a
temperature of 81 and a dew point of 61. Modifying the 12z sounding
for this T/Td show that mixing is nearly extending into dry layer
above a shallow moist layer. The dew point at Amarillo should begin
to fall quickly within the next hour or two and the dryline will
become much sharper in the vicinity of Amarillo. Temperatures west
of the dryline are expected to warm considerably with mid 80s
already observed in the western Panhandle. Typical diurnal density
cycle related to this warming and falling surface pressures should
result in a fairly significant isollabaric response and backing of
low level flow east of the dryline by mid afternoon and continuing
into early evening. This will 1.) ensure low-level moisture
continues to be advected westward, 2.) result in increased low-
level moisture convergence along the dryline to aid in convective
initiation, and 3.) increase low level shear and enhance the
tornado potential. The finer scale details of this process are not
completely clear at this point and additional updates will be
needed based on observational trends. One of the more challenging
aspects of this forecast will be depth of moisture and how that may
change throughout the day. Most of the short term model guidance
suggests a fairly pronounced northward surge of higher 850 mb
theta-e values across the eastern Texas Panhandle. The nose of this
low-level theta-e axis may reach far southwest Kansas by early
evening when the most likely time for tornadoes may occur as
boundary layer starts to stabilize and low level jet increases
causing an increase in 0-1 km shear. Another mesoscale aspect worth
noting that may become particuarly important later today is an
outflow boundary from overnight convection in Kansas that is now
moving slowly south across Beaver County extending east-southeast
to just north of Gage and further into Oklahoma. Stratus is more
extensive north of this boundary with easterly surface winds
enhancing low level shear.
* Threats: All modes of severe weather are expected, including large
hail, damaging winds and tornadoes. At first glance at the short
term guidance the most likely area for tornadoes to occur will be
across the far northeast Texas Panhandle, Beaver County in the
Oklahoma Panhandle, and extending north and east from there outside
of our forecast area. This is due to proximity/timing of the nose
of the low-level theta-e ridge, potential enhanced low level shear
along and north of advancing outflow boundary, and tendency for
stronger low level jet by evening as boundary layer begins to
stabilize. We will refine the specific area of this threat later
today. The primary threat will be large hail and soundings have
evolved to be more favorable for very large/giant hail compared to
prevous days. RAP/HRRR soundings across the eastern Panhandles show
strong instability with MLCAPE in excess of 2,500 J/KG. What is
particuarly concerning about the hail threat is the amount of CAPE
in the hail growth zone and the increased flow from the top of the
HGZ to the anvil layer compared to previous days. 1.5 PVU isotachs
suggest stronger tropopause level flow with further south extent in
the Panhandles as upper jet overspreads west/central Texas into
southwest Oklahoma this evening. In the most persistent sustained
updrafts in this thermodynamic environment, very large hail bigger
than baseballs seems quite possible. We are also concerned about
locally heavy rain for areas that received significant amounts two
days ago. PWATs are not as high but slow moving supercells may
produce locally heavy rainfall amounts and could cause flooding.
* Timing & Location: Convective initiation time based on modifying
the 12z KAMA sounding for expected dew points ahead of the dryline
and temperatures later this afternoon suggests thunderstorms may
begin to develop shortly before 3 PM. Organization may be slow
since deep layer shear is somewhat marginal and there is an
imbalance between shear and instability with CAPE being so high.
Storm motions should be northeasterly at around 20-25 knots before
storms mature/become supercellular, turn right and slow down.
Mature supercell storm motions and speeds should be east-
northeasterly or easterly at around 15 knots based on Bunkers right
moving vectors. Location of this initiation will be dependent on
location of the dryline. Again, there is uncertainty with this
given uncertainty with the depth of the moisture. We will sample
this with a special 19z sounding, but it is entirely possible that
the dryline does not mix east off the Caprock and remains over/near
Amarillo, extending northeast to near Spearman. We will provide an
update after analyzing the 19z sounding.
* Summary: Large hail, damaging winds, and isolated tornadoes could
occur with any storms that form this afternoon across the eastern
Texas and Oklahoma Panhandles and persist into the evening. Large
hail, possibly very large, is the primary threat. The tornado
threat should be maximized in the northeastern portion of the area
from around 7 PM and 10 PM. Locally heavy rainfall with slow moving
storms could cause flooding, particularly in areas that received
significant rainfall on Sunday. Primary uncertainties are where the
dryline will sharpen and thus where convective initiation is most
likely, and where/when the best tornado potential will be. We will
provide updates throughout the day based on observational trends
and short term guidance.

For today, a fairly broad upper level trof over wrn us witll retain
SW flow in place across the srn high plains. Surface winds will
increase and become SW on the Caprock later this morning, causing the
surface dryline to move east across wrn and most of cntrl zones and
eventually slow down and stall somewhere across ern half of the fcst
area later this afternoon. The combination of sufficient moisture
east of the dryline, strong daytime heating and attendant atmospheric
instability, the dryline itself acting as a sfc boundary to help
initiate sfc based tstms, a high cape environment east of the
dryline, decent shear, all suggest that another round of tstms will
develop later this afternoon and continue through the evening hours
east of where the dryline parks itself. Some storms will become
severe, with large hail the dominant primary severe weather threat,
although damaging winds and isolated tornadoes will also pose a
secondary threat. Have painted slgt chc to chc pops ern third of fcst
area for starters this afternoon and evening and also mentioned
psblty of severe in grids and appropriate zones.
A brief break from tstms seems likely on Wednesday and Wednesday
night as the dryline temporarily moves into Oklahoma. No pops during
this period.
A near repeat performance of this afternoon's and evening's severe
weather potential looks plausible for Thursday afternoon and evening
across the ern third of the fcst area as an upper level low pressure
system tracks across the srn and cntrl high plains durg this time
period. Slgt chc pops for tstms were incorporated into the grids
along with psblty of severe.
As the upper level low pressure system continues moving across to the
north of the OK and TX Panhandles on Friday, continued slgt chc pops
across nrn and ern sections based on projected path of the storm
system itself.
Dry weather is then anticipated area wide Friday night through
Saturday night. However, the wrn states upper level trof reloads for
Sunday into early next week with the major long range numerical
weather models indicating this to occur. Therefore, have slgt chc to
chc pops from Sunday through next Tuesday across the area in accordance
with the expected continuation of some semblance of a wrn states
upper level trof.
