.SHORT TERM...
(Tonight and Tuesday)

Early this afternoon, a dry-line was stretching from Aspermont
southwest through Fort Stockton, with dewpoints in the 40s to the
west of it and dewpoints in the mid 60s to the east. As of 1 pm, ML
CAPE of 2500 J/KG existed east of the dry-line, and NAM forecast
soundings show the capping inversion breaking by 3 pm. Meanwhile, an
upper level short-wave trough is forecast to bring lift as it moves
northeast into the Red River region today. Thus, expect
thunderstorms to develop around 3 or 4 pm along the dry-line, then
move east through the early evening hours before dissipating by late
evening as the atmosphere becomes stable. There is a Marginal Risk
of strong to severe thunderstorms due to large instability (strong
updrafts), so strong winds and hail will be possible. Tonight, high
dewpoints in continued warm/moist southerly low level flow will
result in another warm night, with lows in the mid to upper 70s.

Tuesday, an upper level trough will continue over the Rocky
Mountains, with southwest flow aloft bringing in another subtle
upper level short-wave. Meanwhile, the dry-line looks to be in a
similar position to today, with NAM12 showing ML CAPEs potentially
above 4000 J/KG. Once again, the capping inversion looks to break
again by around mid afternoon with isolated storms possible once
again. The 850 mb thermal ridge will strengthen further, up to 28-29
deg C, so it could be rather hot, with highs in the upper 90s to low
100s (perhaps near 104/105 in some western Concho Valley and Big
Country locations where dewpoints will be lower). in the eastern
counties, high dewpoints in the upper 60s/low 70s and temperatures
reaching the upper 90s could result in heat index values in the 103-
108 degree range.

&&

.LONG TERM...
(Tuesday night through Monday)

Isolated showers and thunderstorms that develop along the dryline
may linger into the evening hours Tuesday, with most of the activity
dissipating by mid to late evening. Continued slight chance PoPs for
mainly the central and eastern counties Tuesday evening. Another hot
day is forecast on Wednesday with most locations topping out in the
99 to 104 degree range. The dryline will once again move east into
our western counties during the afternoon hours. Ahead of the
dryline, SBCAPE values will increase to 2000-4000 J/KG, while bulk
shear values remain fairly low, around 15 to 20 knots. An isolated
strong to severe thunderstorm will be possible, with strong gusty
winds being the main concern, given the large dewpoint depressions
that are expected with the very hot temperatures. Once again, most
of this activity will dissipate by mid evening.

Thursday into the weekend, an upper level ridge will build over
Texas resulting in mainly hot and dry conditions. An isolated shower
or thunderstorms is possible across our western counties Thursday
afternoon, but most areas will remain dry. Expect highs between 98
and 102 through this period, with overnight lows in the 70s. The
upper level ridge is then forecast to shift west of the area during
the first part of next week, which may result in our next chance of
precipitation.
