Hail in Texas, June 6, 2022

Area Forecast Discussion
National Weather Service Amarillo TX
606 PM CDT Mon Jun 6 2022

.AVIATION...00Z TAF...

Some isolated to scattered thunderstorms will be possible in the
Oklahoma Panhandle through the first half the 00Z TAF period,
potentially impacting KGUY. Otherwise VFR conditions will prevail
with some MVFR to IFR conditions mainly after 10Z and before 18Z.
Confidence in the IFR CIGs is low at this time, but may very well
come to fruition near sunrise on Tuesday. Winds will mainly be
east to southeast around 10 to 15 kts. KDHT and KGUY may have some
storms impacting the site closer to the end of this TAF period as
well. Will revisit that over the next issuances of TAFs.

.PREV DISCUSSION... /Issued 257 PM CDT Mon Jun 6 2022/

SHORT TERM...Today through Tomorrow Night...

Starting to see some cumulus clouds developing off the higher
terrain in eastern New Mexico this afternoon. Surface winds are
slowly turning back to the southeast this afternoon as a weak
surface low develops in northeast New Mexico. Lingering low level
moisture has dewpoints in the upper 50s to 60s, with the highest
dewpoints across the east southeast Panhandles. A few isolated
strong to severe storms will push eastward into the northwest
Panhandles this afternoon. Much of the Panhandles remains capped
this afternoon, but as the temperatures continue to rise this
afternoon the cap will become weaker from west to east into the
evening hours. MLCAPE values are only around 500-1000 J/kg across
the western Panhandles this afternoon, but bulk shear of 40-50
knots may support a severe storm or two with large hail up to the
size of half dollars and damaging wind gusts up to 60 mph
possible. As the storms push eastward, they will move into
slightly better CAPE values which will increase the hail threat
a bit.

Later this evening a second round of storms may develop across
the eastern two-thirds of the Oklahoma Panhandle and northeast
Texas Panhandle with an upper level shortwave moving across the
area. At the same time the surface low will swing south across
eastern New Mexico with a weak front pushing through the area. A
few clusters of storms may develop along this boundary and with
the help of the shortwave aloft become strong to severe. CAPE
values are slightly higher around 1000-1500 J/kg later tonight as
temperatures cool, along with the cooler air behind the front.
Effective shear values will still be around 40-50 knots, which
will support a few severe storms capable of large hail up to ping
pong size. The wind threat will be a bit lower, but a severe gust
up to 60 mph cannot be ruled out.

Low clouds are expected to move in again tonight across the
forecast area with the return of ample low level moisture and
dewpoints back into the 60s. These low clouds will likely linger
through the morning hours, similar to today. These clouds will
likely lift through the morning hours, but if they linger too long
that could play a key role in how strong the capping inversion is
tomorrow. Another similar setup to today will occur tomorrow as the
surface northeast winds will turn back to the southeast by the
afternoon hours. Storms will begin to develop across the higher
terrain in eastern new Mexico and southeast Colorado.. MLCAPE
values are around 1500-2000 J/kg with 0-6km bulk shear of around
45-55 knots, which will support a few isolated severe storms with
large hail and damaging wind gusts possible. In addition, another
shortwave aloft will help to dynamically enforce storms through
the evening hours. Soundings show elongated hodographs and pretty
high LCLs, so the threat for any tornado remains low at this
time. The best chance for storms will be a bit more widespread
than today with storms possible across the Oklahoma Panhandle and
northern half of the Texas Panhandle.

LONG TERM...Wednesday through Sunday...

The pattern will continue to favor isolated to scattered
thunderstorm chances, especially Wednesday night and possibly
again on Saturday. A ridge will build into the southwestern CONUS
during this time frame resulting in northwesterly flow aloft. Near
the surface, a post frontal upslope flow regime looks to be in
place on Wednesday which could help generate some storms on the
high terrain in eastern NM which should advance into the Panhandle
region during the evening. As these storms move eastward, they
will be entering an environment with better low level moisture
(Tds in the 60s) but may also be contending with a stronger cap
(based on model soundings). While the strongest winds aloft will
stay mostly north of the area, directional shear will be in play
resulting in effective deep layer shear around 30 to 40 knots.
Even the NAM suggest that low clouds won't be an issue Wednesday
which will allow for ample MLCAPE of 2000 to 3000 J/kg. Any storms
that can overcome the cap would pose a large hail and damaging
wind risk. If a supercell can persist into the evening (beyond 7
PM), low level hodographs do lengthen with sufficient SRH values
for a low TOR risk.

Thursday, Friday, and Saturday look fairly similar to Wednesday
but the cap may be even stronger. For now kept the blended PoPs
which keeps a slight chance mention in the northeast zones
Thursday and 10 PoPs on Friday and Saturday. The latest GFS, EC,
and CMC all bring in some storms off the high terrain in response
to another northwest flow shortwave Thursday and Saturday, so
these PoPs may need to go up (especially in the west). Models
do transition to more of a southwest flow going into Sunday and
Monday as a trough advances over the western CONUS while the ridge
shifts east. This may lead to warmer than normal conditions Sunday
into next week.
