.AVIATION...
Scattered showers and thunderstorms southeast of a KILE (Killeen)
to KF44 (Athens) line will dissipate around sunset. Isolated to
scattered showers and thunderstorms are expected to develop along
and east of the I-35 corridor Tuesday afternoon and continue until
sunset with the best chances being well to the east of the TAF
sites. The chances at the TAF sites are way too low to mention in
the TAFs. MVFR ceilings are possible at KACT from 11z through 16z
Tuesday; otherwise, expect VFR conditions through 06z Wednesday.

.SHORT TERM... /Issued 334 PM CDT Mon May 21 2018/
/Through Tonight/

North Texas is currently located between weak troughing aloft
over the TX/LA border and weak ridging nudging in from the west.
Weak flow aloft combined with warm humid conditions at the surface
is leading to scattered afternoon showers and thunderstorms
characteristic of summertime. Most of the showers and storms are
located across southeast Texas closer to the weakness in the
heights aloft, although over the last hour or so, the cumulus
field has become a little more buoyant farther to the west. For
the remainder of the afternoon into the evening hours, we should
see the best chances for scattered thunderstorms to be across our
southeast counties. We`ll keep 20-30% chances through early
evening. It isn`t out of the question to get an isolated storm
as far northwest as the Metroplex. Any convection should diminish
quickly this evening with the loss of heating.

Low level moisture will remain in place overnight with winds
becoming a little more southerly. The lack of a more robust low
level jet should preclude a rapid invasion of stratus, but there
will be overnight cloud cover that develops late tonight into
Tuesday morning.

.LONG TERM... /Issued 334 PM CDT Mon May 21 2018/
/Tuesday Onward/

Broad troughing will persist across the Western US through
midweek with a rather diffuse surface pattern in place. North
Texas will remain within a warm and humid airmass throughout this
time, with temperatures generally 5-10 degrees above normal.
Subtle disturbances rotating through southwesterly flow aloft
should be capable of generating scattered showers and
thunderstorms each afternoon as the atmosphere destabilizes via
diabatic heating. While severe weather is generally not expected
with this activity due to a lack of shear, these storms will be
efficient rain-producers and could cause localized flooding
issues if they remain over the same locations for prolonged time
periods. By Thursday and Friday, an upper ridge axis will begin to
amplify over west Texas, and the axis of highest PWs will be
shifted a bit eastward. This should largely limit afternoon
shower/storm potential to locations east of I-35, which will
remain beneath a weakness aloft. Storms will be of the hit-or-
miss variety, and since coverage is expected to be relatively low,
have kept PoPs around 20-30%.

The Memorial Day weekend forecast may end up hinging on a tropical
circulation set to move northward towards the Gulf Coast. While
the system itself isn`t progged to affect the forecast area
directly, it will have implications on the upstream ridge, which
may become amplified while the low`s circulation moves to our
east. An increasingly amplified ridge would keep the forecast
area dry and subsident, with a potentially hot holiday weekend
with temperatures in the mid/upper 90s. If the Gulf low takes a
bit farther west track, parts of East Texas may experience some
relief with chances for diurnally-driven showers or
thunderstorms continuing.
