...New Short Term, Aviation...

.SHORT TERM... /NEW/
/Now through Sunday Night/

Regional radar imagery has blossomed with convection over the last
1-2 hours coinciding with peak afternoon heating. The 00Z Fort
Worth sounding indicates an uncapped and unstable environment
which will continue to support additional convection for another
few hours. Latest RAP objective analysis also shows an axis of low
level convergence extending from around Stephenville through the
Metroplex and northeast into Southern Oklahoma. All of this points
to continued chances for showers and thunderstorms (developing
along the outflow of dying storms) through the evening before
activity diminishes with loss of heating. Heavy rainfall and
frequent lightning will be the main threats, although a strong
wind gust can't be ruled out.

Overnight, after this evening's activity diminishes, we should
remain fairly quiet although it's not out of the question that a
few isolated showers develop well after midnight. The slow moving
upper low will continue to pivot through North Texas on Sunday.
Similar to the last few days, afternoon heating and an uncapped
environment should support scattered showers and thunderstorms
across the region. Additional showers and thunderstorms are likely
to develop well off to our northwest tomorrow afternoon as well
and these may move with the northwest flow along the back side of
the upper trough into the region overnight tomorrow night. We'll
continue to refine this part of the forecast through tomorrow, but
we'll continue with fairly high rain chances Sunday night.

.LONG TERM... /Issued 339 PM CDT Sat Jun 5 2021/
/Sunday Night Onward/

The potential for a complex of thunderstorms to impact the area
Sunday night into Monday morning has increased. A departing upper
level low, coupled with an approaching shortwave will induce
strong warm-air advection into a region with modest amounts of
instability. Isentropic ascent analysis suggest a rapid increase
in pressure advection across northwestern portions of North Texas
shortly after midnight. Instability values in excess of 2000 J/kg
are likely to be in place, likely leading to a quick development
of convection. As the convection develops a cold pool, a
strengthening low-level jet may enhance ascent, leading a line of
storms gradually moving south/southeast through the early Monday
morning hours.

The main concern with the overnight convection will be the
potential for strong to damaging winds as well as heavy
precipitation. Precipitable water values over 1.5" are likely to
be in place, and if the line of storms remains fairly slow moving
or there is training taking place, a quick 2-3 inches of rain will
be possible. Those higher end amounts are likely to be isolated
and confidence remains too low at this time to pinpoint exact
location. Given the expected origination of the complex of storms
and direction of the low-level jet, the most likely location would
be somewhere west of Interstate 35.

Monday's forecast will be heavily dependent on what occurs Sunday
night. If an MCV develops and moves overhead, it's possible we
continue to see scattered convection through the afternoon hours.
If this is the case, increased cloud cover should help keep
daytime temperatures mainly in the lower to mid 80s.

As we go into Tuesday, synoptic scale subsidence will likely be
on the rise as an upper ridge strengthens across West Texas. This
will likely keep areas west of I-35 dry through the rest of the
week. Subtle disturbances will be on the periphery of the area of
higher pressure, potentially firing off scattered showers and
storms in the afternoon Tuesday and Wednesday east of I-35. With
dry and sunny conditions mid-week, a few locations west of US-281
may reach the lower to mid 90s with heat index values near the
triple digits. Heat index values elsewhere are likely to remain
between 90-95 degrees.

As we approach next weekend, the upper ridge to our west will
begin to break down. Whether we transition to northwesterly flow
aloft remains a bit uncertain given a few of the ensemble members
want to bring a tropical wave onshore next Sunday. Regardless of
which scenario plays out, slight rain chances will likely return
to the forecast the latter half of next weekend.

.AVIATION... /NEW/
/00Z TAFs/

VFR generally prevails across the region outside of convection.
Thunderstorms are ongoing mainly to the north of the Metroplex and
to the southwest near Stephenville. We'll continue with a VCTS at
all sites through 4Z although activity should begin to wane with
loss of daytime heating. We started the Metroplex TAFs off with a
TEMPO -TSRA, but if trends to the north continue we may pull this
early. Otherwise, a TEMPO for MVFR cigs in the morning is the only
other concern at this time. Additional scattered afternoon showers
and storms are expected on Sunday with perhaps a better chance for
organized storms late Sunday night.
