Area Forecast Discussion

651 AM CDT Tue Jun 1 2021

.AVIATION...

Showers and thunderstorms will continue to affect the eastern
sites for the next hour or two with gusty winds. They should
mainly dry out from mid-morning through the afternoon. LRD site
could see convection off and on through the day. Another round of
thunderstorms is possible again tonight, but confidence in timing
is not enough to include in TAFs yet. After morning gusty winds,
expect light to moderate winds the remainder of the period.

.PREV DISCUSSION... /Issued 336 AM CDT Tue Jun 1 2021/

SHORT TERM (Today through Wednesday)...

Convection moving through the area this morning is associated with a
vigorous mid-level shortwave moving across the area. Guidance has
been consistent in pushing this squall line across the area tonight,
but not on the placement of it. Overall, a general east to
southeastward motion is expected. Latest HRRR runs not bringing much
of this to the coast, but pushing the main piece south into BRO
forecast area. Current radar trends support this with a notable
push south in the southern end of the line. A reinforcement of the
mid-level shortwave noted in the NAM lines up nicely with this
movement. Strong winds and marginally severe hail will remain
possible as this moves through the unstable environment. Notable
at time of this writing, ML CAPE has decreased ahead of this line
to below 1500 J/KG. Still sufficient to maintain strong storms,
especially an already organized system, but the decrease is worth
nothing.

Once this convection moves through...largely out of the area by 9am,
think there will be a break in convection for much of the area.
Though another weaker shortwave is progged to move south of the area
and keep convection going there...could see continued convection
across the southern border of our forecast area. Another round of
convection is possible tonight with again storms moving out of
Mexico or southwest Texas. This convection will be ahead of another
stronger and deeper shortwave progged to move through tomorrow. Thus
rain chances 40-50% continue through the day Wednesday.

Below normal daytime highs are expected today and tomorrow with near
normal lows.

LONG TERM (Wednesday Night through Monday)...

Not much of a change from the previous long-term package. Scattered
to numerous convection is expected to continue through most of the
extended period in response to several disturbances rippling in the
flow aloft as a trough centered near the Great Lakes region lifts to
the northeast and a closed low develops behind over Texas. The
combination of a weak to moderately unstable atmosphere, a weak cap
and plentiful deep moisture available will allow for thunderstorms
to develop daily through early next week, with some of these storms
possibly becoming strong at times. Given the already saturated soils
from all the rain received over the past few weeks, localized
flooding will certainly remain a possibility, particularly with slow
moving cells or convective lines. Current forecast calls for
rainfall totals to be anywhere between 2-5 inches across much of
South Texas through the entire forecast period (including short-
term), with locally higher amounts possible. Interests along low-
lying/flood prone areas should stay tuned to the forecast for the
latest updates over the coming days. Rain chances may diminish
slightly Monday to Tuesday next week.

Even though humid conditions have been leading to sweltering days
across the region lately, below to near normal temperatures will
continue into the extended with highs in the 80s to 90s, and lows
generally in the 70s. Winds will remain light to moderate through
the period, under partly to mostly cloudy skies.

MARINE...

Generally weak to moderate onshore flow will persist today and
Tuesday. Showers and thunderstorms will be possible both days. A
weak onshore flow will is expected Wednesday night through
Friday. Scattered to numerous showers and thunderstorms will be
possible Wednesday night through through Saturday. Onshore flow
will increase to weak to moderate levels on Saturday.y.
