.SHORT TERM... /NEW/
Update:

The northern cluster of storms mentioned below has maintained its
intensity overnight and is currently moving across the Red River.
While the strongest storms should remain in Oklahoma, an isolated
severe storm will be possible over the next few hours. In addition
to this, training storms may lead to localized flooding within our
Red River counties. The southern complex mentioned below struggled
to organize into anything more than a few showers due to strong
convective inhibition. The cap is projected to weaken over the
next few hours, which should allow for storms to blossom across
most of the eastern half of the forecast area by mid-late morning.

Previous Discussion:
/Through Friday Night/

A period of active weather will unfold early this morning and
continue for the next few days. Thunderstorms developed last night
over the Caprock Escarpment and have moved east-northeast through
the pre-dawn hours. As of this writing, there are two distinct
areas we're watching...one is currently near Guthrie and another
is west of San Angelo. The northern cluster will have the highest
severe potential, with damaging winds and large hail being the
main threats. This cluster may skirt across our far northwestern
counties early this morning, but a bulk of the activity should
remain to our north and northwest.

The southernmost cluster struggled to organize for most of the
night, but should blossom as it moves east into more positively
buoyant air. We expect it to move into our forecast area near
sunrise and approach the I-35 corridor near the morning commute.
Storm coverage should increase as the cluster moves into and east
of the I-35 corridor once it taps into ongoing low-level warm
advection and erodes the capping that currently overspreads the
region. We expect a blossoming of loosely-organized convection
east of I-35 this morning continuing into the afternoon, slowly
moving east this afternoon. There will be a low severe threat with
this activity, with large hail being the main threat and a lower
threat of damaging wind gusts. The tornado threat will be highest
to our east and northeast, but it is non-zero in our area. There
is also a risk of flooding this morning into the early afternoon.
Low confidence about the coverage of storms precludes issuance of
a flood watch...but isolated instances of minor flooding or urban
flash flooding will be possible if training storms develop.

The aforementioned activity will largely take place along/ahead
of a leading shortwave trough. On the surface, a dryline currently
over West Texas is expected to move into our forecast area this
afternoon. The boundary is forecast to stall within ~25 miles of
Montague, Mineral Wells, and Goldthwaite. The morning activity
will stabilize the airmass...but clearing early in the afternoon
may provide enough recovery for isolated storms to develop along
the boundary late in the afternoon. Any storms that are able to
develop will be capable of becoming discrete supercells capable
of producing large hail, damaging wind gusts, and possibly a
tornado. This is a conditional severe threat, with our confidence
of any storm developing ~20%. Any storms should weaken as they
move east of the dryline into more stable air and dissipate after
sunset.

.LONG TERM... /Issued 313 AM CDT Fri Apr 26 2024/
/Saturday Onward/

Large hail, damaging winds, a few tornadoes and flash flooding
will all be a threat Saturday and Sunday as 2 rounds of storms
are possible.

Round 1 - Saturday Afternoon

The severe weather threat during the day on Saturday will remain
conditional, and it's quite possible we see no storms until the
evening hours as the main trough inches closer to our region (more
on that below).

The thermodynamic and kinematic environment atop our region
suggests there will be a threat for severe weather, **should
storms develop**. With a highly unstable atmosphere, steep mid-
level lapse rates and sufficient effective shear, any storm would
likely exhibit rotating updrafts that could produce large hail,
damaging winds and even a few tornadoes.

There continues to be some question as to the strength of the
capping inversion, especially in the afternoon. Should the cap
remain fairly strong, storms are unlikely to develop. However, a
weak or non-existent cap would allow for updrafts to quickly
strengthen should there be a source of lift.

With the strongest forcing for ascent still across NM and far W
Texas during the day, we'll have to rely on daytime heating for
any storm development. More low-level clouds would likely to
delay or inhibit afternoon convection. The inverse is also
true...breaks in the clouds would increase the potential for
storms to develop.

If storms develop, any convection that persists into the late
afternoon/evening hours will see an heightened potential for a
tornado or two. We'll have to continue to monitor the higher
resolution guidance as confidence in afternoon convection remains
low.

Round 2 - Saturday Night - Sunday

Confidence in thunderstorms impacting North and Central Texas
Saturday night is high as strong forcing for ascent moves closer
to our region. With increasing southerly flow, moisture content
will be on the rise overnight. A highly unstable atmosphere,
strong low-level shear and increasing forcing for ascent will lead
to the development of severe thunderstorms along a dryline. With
the dryline just west of our region around sunset, convective
initiation is likely to occur just outside of our area. This
activity, although initially supercellular in nature, will merge
in to a line of storms that will sweep eastward across much of our
region. The line of storms is likely to be N-S oriented, moving
eastward through the early Sunday morning hours. Damaging wind
gusts and large hail would be the main hazards. However, with 40+
knots of 0-3km shear in place, there will be a low threat for
QLCS tornadoes. Any segment of the line that gains a more NW-SE
orientation will be able to maximize the available vorticity,
increasing the potential for a quick spin-up.

Additionally, there will be a risk for heavy rainfall across
portions of North Texas. The risk for flash flooding will be
highest along the Red River, where a few locations may pick up as
much 3+ inches of rain in a short period of time. Given the
nocturnal nature of this event, it's important to pay attention
while driving as flooded roads are much harder to spot at night.
Remember, if you encounter a flooded road, Turn Around, Don't
Drown.

By sunrise Sunday, the I-35 corridor is likely going to be
experiencing the line of thunderstorms. There will be a continued
threat for large hail and damaging winds. By this time, slightly
weaker low-level shear will be in place, slightly reducing the
tornado potential. Nonetheless, an isolated embedded tornado
cannot be ruled out.

The dryline will stall before exiting our region, then retreat
northwestward through the day. This will keep North and Central
Texas in a moist environment with additional storm chances in the
afternoon. The severe weather threat Sunday will mainly be along
and east of I-35, where instability will be the highest.

Monday Onward

Deep southerly flow will continue across the region, keeping the
potential for diurnally driven convection alive Monday through
Wednesday. Compact impulses will be moving overhead, leading to
occasional showers and storms. Weak shear each day will likely
keep the severe weather threat low, however, a strong storm or two
cannot be ruled out. The main hazards would be small hail and
gusty winds.

There remains fairly good agreement that a cold front will be
pushing southward across the Plains, arriving to our region
Thursday afternoon. With plenty of moisture expected, we'll have
to monitor the parameter space as yet another severe day is
possible. Details in timing/hazards will become more clear in the
coming days.

.AVIATION... /NEW/
/12Z TAFs/

We have maintained VCTS and a TEMPO for TS at the D10 and ACT
terminals in the 12Z TAFs, but our confidence of this is waning.
Forecast soundings and CAM guidance continues to point toward an
increase of convective activity near the airports over the next
few hours, but we will reassess when our morning sounding data
starts populating in the next 30 mins to hour. If storms develop,
this likely will not be a "one and done" storm event, meaning
redevelopment after the initial storms will be likely before all
convection moves east early this afternoon.

Improving flight conditions are expected after the storms move
east. There is a 15% chance of additional isolated storms
developing late in the day, but most of this activity should
remain west of the TAF terminals. Another surge of MVFR stratus is
expected tonight.
