Area Forecast Discussion
National Weather Service Amarillo TX
608 PM CDT Sat Jun 8 2019

.AVIATION...
The 00Z TAF period will start off with light winds out of the
south in VFR conditions. A cold front will move through from the
north between 07Z and 12Z. This front will bring strong gusty
winds out of the north along with MVFR CIGs for all three
terminals. There still is some question on the exact timing of the
front and just how strong the winds will be behind it. Right now,
have 25-35 kts gusting 35-40 kts in the TAFs. If this front comes
in quicker we could see higher winds with gust 45-50 kts.

.PREV DISCUSSION... /Issued 329 PM CDT Sat Jun 8 2019/

SHORT TERM...Tonight and Sunday.
For this evening, the mid level capping inversion continues to hold
tough as of this writing this afternoon across the fcst area. Still
a fair amount of convective inhibition as well. Therefore, it
remains to be seen whether any tstms will develop east of the
dryline. Retained pops across parts of cntrl zones through early
this evening from earlier fcst pckg as confidence was not high
enough to remove them and did not want to flip flop either.

A strong cold front will move through the OK and TX Panhandles late
tonight and early Sunday morning. Rather decent pressure rises and
associated steep pressure gradient behind this boundary suggests
surface winds may approach or even exceed Wind Advisory criteria for
at least parts of the fcst area for a few to several hours. Have
increased wind speeds behind the cold front to just short of our 30
knot Wind Advisory criteria. Confidence was not high enough to issue
an NPW product due to some uncertainty as to how the synoptic
situation will play out. Later shifts may need to consider some sort
of wind highlight for parts of the area late tonight into Sunday if
confidence improves with respect to timing, areal extent, and wind
speeds. Retained slgt chc pops for late tonight across the OK
Panhandle. Also kept in slgt chc to chc pops across northern and
eastern sections for Sunday before much drier air invades the
region. Below normal temperatures are expected on Sunday.

LONG TERM (Monday Night through Saturday)...

The Panhandles will be on the northern periphery of an H5 ridge
extending north from strong 594 H5 high center over northern Mex
early Monday. This will be quickly suppressed south and west as a
series of S/WV troughs move SE from S/CEN Canada carving out a
rather substantial trough across the mid WEST and well south
into the CEN MS River Valley through Thursday. On Monday, unusually
strong SFC high pressure for early June will dominate in the wake
of the strong Sunday FROPA (a result form one on the initial
S/WVs). This will keep things dry and cool to start off the week.

Although the front will have pushed to the coast, deep moisture will
pool along and behind the front and will not be far away (Cen
Texas). Given this, models show a relatively quick recovery in
moisture Monday night and Tuesday as the low level high center
shifts east and SFC low pressure develops across ERN NM drawing
moisture north. Meanwhile, models are in good agreement the next
cold front will race down to meet the moisture as a strong S/WV
dives SE across the CEN Plains late Tuesday. While the best energy
from the S/WV itself may remain to the north, it appears the exit
region of a 110 kt+ jet streak will provide large scale lift
enhancing precip chances. That much models have good agreement on,
however enough differences in how much moisture and instability
will be present to provide some uncertainty in coverage, but even
moreso wrt thunderstorm strength/character with this system. Wind
shear is forecast to be strong with good low level turning
heading into Tue night, increasing the SVR potential. This will
make moisture recovery and CAPE that much more important as wind
shear suggests a relatively high ceiling WRT SVR potential. Of
course timing of the disturbance and front will also be key and
can't be overly confident in that this far out. That all said, all
we can say at this point is high end CHC POPS looks good for
Tuesday night (slight chc Tue AFTN) for most of the area and
there is certainly a conditional potential for SVR storms if
moisture recovery is sufficient.

Assuming all the aforementioned timing holds, Wed should be cooler
and drier in the wake of the week FROPA late Tue. Models again show
a quick recovery and moisture return for Thu as SFC high shifts east
and pressures fall again to the west. This could set the stage for
TSTM episode Thu and Thu night as another NW flow disturbance
comes into play. Again given impressive wind shear progs, it could
become interesting (high ceiling for SVR potential) given enough
moisture recovery and assuming timing plays here out well. While
models (esp GFS) do suggest show sufficient recovery, how far
south the previous boundary may be shoved further south than
indicated by models with help of TSTM outflow (should Tue play
out as advertised) adds some uncertainty despite good model
agreement. Again, CHC POPs seem reasonable (especially being in
the wet pattern we are in). We will have to see how details play
out wrt potential impacts from these storms as details in moisture
become more clear.

It appears temps will climb to more normal values heading into the
weekend after several below normal days earlier in the week. The
ridge in the WRN US will be broken down and replaced by troughing
which means s/wvs in developing SW flow aloft will maintain SLT CHC
POPS for at least the northern portion of the area and suggest more
interesting weather possible beyond the current forecast period as
well.

This Hazardous Weather Outlook is for the Texas and Oklahoma
Panhandles.

.DAY ONE...This Afternoon and Tonight.

Isolated thunderstorms are possible through early this evening
across central sections of the Oklahoma and Texas Panhandles, and
then across the Oklahoma Panhandle after midnight tonight. If
storms develop, a few will have the potential to become strong to
severe with large hail and damaging winds the primary hazards.

Sustained north winds near 35 mph are expected late tonight across
parts of the area behind a strong cold front, and a Wind Advisory
may become necessary.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

Sustained north winds near 35 mph are expected Sunday across
parts of the Oklahoma and Texas Panhandles behind a strong cold
front, and a Wind Advisory may become necessary.

Thunderstorms are possible Sunday afternoon across eastern sections
of the area. If storms form, they are forecast to remain below
severe levels at this time.

Additional thunderstorms will be possible across the Oklahoma and
Texas Panhandles Tuesday afternoon, Tuesday night, and Wednesday
night through Thursday night. Some storms that develop during
these time periods will have the potential to become strong to
