Area Forecast Discussion
National Weather Service Amarillo TX
656 PM CDT Tue May 25 2021

.AVIATION...00z TAF Cycle...

Thunderstorms west of Amarillo are slowly moving east at 10 mph,
and assuming they hold together storms will be impacting the KAMA
terminal around 01z. This could lead to gusty winds, hail and
MVFR/IFR cigs/vsbys with heavy rain possible. Also can't rule out
some MVFR/IFR cigs later tonight in wake of storm activity. Will
amend if needed. Storms should remain east of KGUY and KDHT, with
lower chance for MVFR/IFR cigs at those terminals.

.PREV DISCUSSION... /Issued 303 PM CDT Tue May 25 2021/

SHORT TERM...Today through Wednesday Night...

Satellite this afternoon shows a couple boundaries around the
Panhandles this afternoon. The cold front is sagging into the
OK Panhandle and looks to be from Felt to Guymon to Turpin. There
is another boundary showing up from Beaver to Gruver to Fritch to
just east of Wayside that is an outflow boundary from the MCV over
eastern OK. The southeastern winds from the outflow are meeting up
with the southwesterly flow and popping clouds all along the
boundary. If you look closely, we can see some orphan anvils,
particularly down by Panhandle and Groom. These attempts at
updrafts will continue to break what little cap likely exists over
the area as the special 19Z sounding from AMA shows very little
cap. With little to no CIN, storms will not take much to fire up
along either boundary. The dry line is over in NM and is progged
to shift eastward. There is a mid level shortwave that is also on
its way here and could also provide some uplift to help fire up
storms or enhance the ones ongoing this evening when it arrives.
Beside all the lift options, there is plenty of moisture to work
with for storms today. Dewpoints are currently in the 50s and 60s
around the Panhandles. The special sounding shows some dry air in
the mid levels that may help with hail growth. MLCAPE around the
area is forecast to be around 2500-3500 J/kg, which could mean
hail up to 2 or 3 inches could be possible. DCAPE is forecast to
be around 1500-2000 J/kg. Bulk shear is around 20 to 30 kts so
storm mode will be multicellular in the north where the shear is
less and could be supercellular in the south where shear is
better. Storm motion looks to be around 20kts, so we could be
looking at 70 to 80 mph gusts from a good downburst. LCL heights
today are fairly high at 2000m and 0-1km shear is almost non-
existent. 0-3km shear isn't terribly excited at 100 m2/s2, so not
looking for tornado potential. If shear along a boundary
increases, we might have a small brief spin up. Storms should
mostly move out of the area by 06Z tonight, although could have a
lingering storm in the far southeast.

The NAM indicates the presence of low level moisture overnight
for a low cloud deck over all but the western TX Panhandle. This
could limit storm potential for Wednesday if the low clouds are
realized. Instability for tomorrow is even better for today if
storms happen. MLCAPE could be upwards of 3500-4000 J/kg with
DCAPE of 1000-1500 J/kg. LCL's lower tomorrow to around 1000m and
low level shear increases. Thus Wednesday could see storms with
very large hail, damaging winds and tornadoes. PWATs increase for
tomorrow as well to being near or over 90th percentile, so
flooding issues may become a concern again. The big question will
be if there are boundaries around, other than the dry line and if
the low clouds materialize.

Beat

LONG TERM...Thursday through Monday...
As we wrap up the month of May, more showers and thunderstorms are
in the forecast. The main synoptic pattern favors daily chances
for thunderstorms, in which each day we could see some severe
storms. Perhaps a small break on Saturday before chances pick
back up on Sunday.

On Thursday and Friday, H500 flow will result in perturbations
along the mean SSW-NNE flow. In-conjunction with a dryline setting
up across the eastern Panhandles on Thursday retreating back to
the west on Friday, the combination of surface boundary and upper
level disturbances with good low level moisture will result in
diurnally driven thunderstorms. In particular on Friday, a cold
front will move south, adding an additional surface boundary for
potential lift. Shear will be limited, but should be suffice to
generate some thunderstorms. High temperatures will drop from mid
80s on Thursday to low and mid 70s by Friday. A temporary break in
thunderstorms activity on Saturday as stable airmass fills in
behind front, with the only exception for the far SE TX Panhandle
with a thunderstorm chance early Saturday morning.

Continuing on Sunday and Monday, a deepening mid level neutral
tilted trough over the SW CONUS will surge sfc moisture northward
along and ahead of dryline developing in eastern New Mexico.This
will bring thunderstorm chances back to the Panhandles where some
storms could be severe as some of the latest 25/12Z model and
numerical data shows a series of mid level disturbances moving
into the Panhandles. Temperatures Saturday through Monday will
actually be a bit below average as we approach the end of May.
