.SHORT TERM...
(Tonight through Monday night)
Issued at 1127 PM CDT Sat Jun 13 2026

Strong outflow from western storms this evening didn`t do the
southwest Panhandles any favors wrt rainfall amounts, however we
are seeing redevelopment near Amarillo as the main cold front is
approaching the area. Even late tonight and into Sunday morning
the HRRR and NAM maintain elevated instability above the cooler
more stable surface airmass behind the front, so while POPs will
be decreasing, isolated to scattered showers and storms will
remain in the forecast especially for the southern and central
Panhandles. MUCAPE is forecast to remain less than 800 j/kg, so
the main threat should be from heavy downpours and lighting. While
the cap decreases, some remains present as does H7 moisture
transport above the frontal zone. Given this, low POPs persist
into Sunday night mainly across the southern Panhandles. WPC
marginal threat for heavy rainfall remains across the southwest
3rd of the Texas Panhandle.

NW mid level flow will persist Monday as series of S/WVs maintain
broad ERN US troughing. Decent disturbances in this flow will
move across the region on Monday. Models suggest a pretty good cap
will be in place, but some manage to break this w/ help of these
disturbances and some H7 moisture transport. The western counties
are currently favored and given adequate wind shear but marginal
CAPE. POPs of 10-40 percent favoring the west seems reasonable
for now. Highs will be below normal and generally in the 70s the
next two afternoons.

.LONG TERM...
(Tuesday through next Saturday)
Issued at 1127 PM CDT Sat Jun 13 2026

After a couple days with below normal temps behind the front,
will see a warmup on Tuesday closer to average and will warm well
above normal on Wednesday. The heat seems to be more as a result
of downsloping SW low level flow and dry air as H5 ridging isn`t
impressive. The newly added water in the soil should matter wrt
mitigating max temps, but difficult to say how much. Widespread
100-105 temps are forecast. Will see if this decreases as models
adjust ground moisture, but it will be hot even if this is
currently slightly overdone. With continued NW flow, the next
front will arrive quickly and end the brief heat wave as highs are
forecast to be in the 80s to low 90s Thu.

Rain chances will return Friday into the weekend as models
indicate the monsoon influence returns from the west. H5 high
pressure will remain across the Desert SW leading to ridge roller
disturbances which will be the catalyst for generating storms
that track into the area from the west. Current forecast strength
and position of the ridge slightly favors the NE for POPs but not
confident in details this far out. It also favors increasing
temperatures once again over the weekend.

.AVIATION...
(12Z TAFS)
Issued at 619 AM CDT Sun Jun 14 2026

MVFR ceilings are being observed at KAMA and they could form at
KDHT over the next few hours. The low clouds should lift by late
morning and a return to VFR conditions is expected through the
rest of this TAF cycle. There are low chances for showers or
storms at the terminals during the day, but confidence is not
high enough to include PROB30 mentions at this time. The wind will
be out of the northeast with gusts up to 25-30 kts at the sites
before decreasing and turning clockwise through the rest of this
TAF issuance.
