Area Forecast Discussion

245 PM CDT Mon Jun 14 2021

.SHORT TERM (Tonight through Tuesday Night)...

Hot and humid conditions will continue this afternoon with
heat indices 105-109 across the Coastal Bend.  Expect isolated
showers and thunderstorms across the northeast Coastal Bend late
this afternoon and evening as a weak S/W moves through. Moisture
(PWATs 1.9") and instability (mixed layer capes 3000 j/kg) is
highest in that area and the cap is weakest. Storms were currently
moving SW across Wharton and Matagorda Counties and could approach
Victoria and Calhoun Counties by 5pm. Given the environmental
conditions a strong storm is possible. Convection should
dissipate after sunset and winds become light and variable. This
will allow for areas of fog to develop late tonight/toward sunrise
Tuesday. Some patchy dense fog will be possible 10-13z Tue.
Continued hot and mostly dry on Tuesday with temperatures/heat
indices a degree or two less than today. Another mid level S/W
will cross the NE Coastal Bend resulting in isolated/scattered
showers and thunderstorms in the afternoon, mainly over the
Victoria area. Winds will be light and variable, becoming onshore
around 10 knots in the afternoon. Areas/Patchy fog is expected
again Tuesday Night across the Coastal Plains.

&&

.LONG TERM (Wednesday through Monday)...

The upper air pattern at the beginning of the long term period will
be dominated by a 600 decameter ridge over the Four Corners region.
After some early morning fog Wednesday morning, a shortwave trough
moving under this ridge will skirt southwest along the Texas coast.
This may allow for a few showers to develop, but expect most
activity to remain relegated to the sea breeze during the late
morning and afternoon hours across the coastal counties. Similar
conditions are expected again on Thursday with a few showers or
storms developing along the sea breeze. Expect heat to persist both
days with afternoon heat index values in the 100-105 degree range.

Attention for Thursday into the weekend will focus on the evolution
of an elongated trough currently located in the Bay of Campeche.
Satellite imagery through the course of today has shown shower and
thunderstorm activity associated with this feature remains largely
disorganized. ASCAT passes have unfortunately missed sampling the
bay this afternoon, but surface observations still indicated the
presence of the surface trough. 850-250 MB shear analysis shows a
corridor of very strong wind shear stretching from south of
Brownsville to the Yucatan Peninsula and the presence of this shear
axis will likely keep the surface trough disorganized and stationary
over the next 48 hours. However, as mid-level ridging shifts
westward on Thursday and an upper level trough develops and
elongates along the Texas coast, the Bay of Campeche trough is
expected to lift northward towards the central Gulf of Mexico and
eventually the northern Gulf of Mexico by Friday.

Global deterministic and ensemble guidance remains consistent in
this general northward trend in movement with the trough developing
into a surface low and likely a tropical depression by Friday as it
interacts with an easterly moving wave from the Caribbean.
Increasing shear along the Texas coast, however, may contribute to a
rather lop-sided or asymmetrical system, with the majority of rain
and wind on the north and east side of whatever develops. Have
maintained consistency with the previous forecast and continued to
advertise increasingly hazardous marine conditions as swell from
this system arrives by Friday. Hazardous beach and marine conditions
may continue through Sunday before improving. In the wake of this
system, expect heat to build across South Texas.

.MARINE...

Isolated showers and thunderstorms will be possible along the
coast mainly north of Port Aransas late this afternoon and
Tuesday afternoon with the onshore flow remaining weak. Light
onshore winds continue through mid-week, becoming northeasterly
and moderate Friday into Saturday as a low pressure system into
the northern Gulf of Mexico. The National Hurricane Center
indicates this system has a high chance of becoming a tropical
depression late in the week. Small Craft Advisory conditions may
begin over the offshore waters Friday afternoon due to increasing
swells. Isolated showers and thunderstorms will be possible
Wednesday through Thursday night, becoming scattered Friday
through Saturday Night. Mariners should monitor the latest
information from the National Hurricane Center.
