Area Forecast Discussion
National Weather Service Amarillo TX
658 PM CDT MON JUN 6 2016

.Update...
Made minor adjustments to the first few hours of the grids to
capture trends on radar. Most immediate concern is the cluster of
storms over far southwest Kansas that will enter Texas County in the
Oklahoma Panhandle shortly. Around 35 knots of shear through the
storm depth has been sufficient for sustained updrafts and a gust of
44 knots was recently measured at Stanton County Airport in Kansas.
Similar gusts, potentially higher to marginal severe criteria, are
expected as the storm moves south. Latest surface observations ahead
of these storms show quite a substantial temperature/dew point
spread indicating deep mixing. Therefore wind is the primary threat
with the most intense cores. Marginally severe hail may be possible,
but MLCAPE is quite meager. These isolated severe threat should
subside late this evening as the boundary layer begins to stabilize,
but storms may continue until early tonight and could move as far
south as Amarillo.

.Prev Discussion... /Issued 602 PM CDT MON JUN 6 2016/

Aviation.../For the 00z TAFs/
Thunderstorms over southwest Kansas with strong wind gusts will
approach Guymon terminal by around 00z. Gusts up to around 45 knots
have occurred with these storms at Stanton County Municiple Airport,
and the environment is favorable for similar gusts with these storms.
Thunderstorms are also increasing near the New Mexico/Colorado border
along the Johnson Mesa. These storms should approach Dalhart around
01z or just after with similar concern for strong gusts. Storms may
approach Amarillo late this evening but confidence in the terminal
being impacted is less than at Dalhart and Guymon given decreasing
instability. Westerly or northwesterly winds, possibly variable at
times will occur in the wake of the storms until southwesterly flow
becomes dominate again later in the night and persisting tomorrow. A
similar cycle will occur tomorrow with storms possibly affecting
Guymon and Dalhart toward the end of the TAF period.

Prev Discussion... /Issued 457 PM CDT MON JUN 6 2016/

Short Term.../Tonight through Tuesday/

Afternoon mountain convection is already underway as visible via
regional radar mosaic from Pikes Peak, CO to Las Vegas, NM. Storms
this afternoon and overnight will have a much better chance to move
into the Panhandles than yesterday thanks to a more substantial
shortwave trough rounding the periphery of the upper ridge. Unlike
yesterday, this shortwave will also allow discrete convection to
develop over southeastern Colorado and southwestern Kansas. South-
southeast storm motions for the discrete cells will help them into
the Oklahoma Panhandle before merging with mountain convection to
form a multi-cell complex. This complex will take a more southerly
motion to impact mainly the western and central portion of the
Panhandles.

Widespread severe weather is not anticipated with storms this
afternoon and overnight, but an isolated strong to marginally severe
storm can't be ruled out prior to midnight across the northwestern
corner of the CWA. In this area, mixed layer CAPE values are in the
500-1000 J/kg range with effective deep layer shear around 30kt. As
the complex moves further into the CWA, it will be moving into a
less favorable environment thermodynamically which will limit any
marginal severe storm potential.

Southwesterly winds return tomorrow and help temperatures across the
southwestern Texas Panhandle warm into the 90s. This setup should
allow temperatures at the base of Palo Duro Canyon warm into the mid
to upper 90s. Afternoon mountain convection are possible but they
will likely struggle to reach as far into the Panhandles again.

Long Term.../Tuesday Night Through Sunday/

Summer temps on tap through the period with highs near or slightly
above climo through the period partly due to influence of weak s/wv
ridging nearby. There will be isold to sct aftn and evening storms
assoc w/ weak s/wvs in nw flow aloft riding around the ridge through
the week. the best chance for storms assoc w/ this activity will be
across far wrn Texas and wrn half of OK Panhandles given position of
H7 Theta-e ridge and closer proximity to mountain/dry line initiation
areas. Combination of evening LLJ development with elevated low level
helicity...high downdraft cape values and steep mid level lapse rates
will provide at a low potential for an isolated SVR storm each
aftn/evening but organized SVR threat will be limited by more modest
deep layer shear values and marginal moisture values.

Pattern changes heading into the weekend as the weak s/wv ridge is
replaced by troughing across the western US. This will produce a
transition to sw flow aloft while moisture increases with h85-h7
theta-e ridging noted across the area. This should bring pops east
to include the entire area over the weekend mainly in aftn and
evening periods but have confined to slt chc most areas for now. GFS
and ECMWF handling of the evolution of the aforementioned system
becomes very cloudy as it approaches from the west and run to run
consistency has not been great. Some solutions have been very
interesting/aggressive as they show the base of the trough breaking
off into an up low which directly impacts the Panhandles as a cold
front comes into play Monday. However there is great uncertainty in
this and 12Z ECMWF really backed off previous forecasts which plowed
this system directly across the area on Monday. Will show some
modestly higher pops on Monday...but conservative approach perhaps
below 12Z POP blend seems like best choice for now.
