.PREV DISCUSSION... /issued 336 PM CDT Tue Jun 27 2017/

DISCUSSION...
Weather map showing mainly easterly flow over the area. Radar
shows scattered to numerous slow moving showers and thunderstorms
over most of the area this afternoon. Some of these storms
produced 3-5" of rain over central Beaumont per DD6 gauges with
flash flood warning continuing over the region. Other areas of
2-4" occurring the last 3 hours over SE Calcasieu parish and
between the southern end of Calcasieu Lake and Cameron.

The upper level trough/low over the Texas coast and Western Gulf
will be slow moving through Friday. This coupled with continued
high Gulf moisture (Precip H20 expected to be at or above 2"
through Friday), periods of showers and thunderstorms, with the
best chances along and south of I-10 into the coastal waters at
any given time, can be expected. Due to the slow movement,
isolated locations could see minor flooding, especially locations
that are exceedingly wet from the recent rain.

By Friday evening into the weekend, the mid level trough axis
should move east of the area with high pressure and slightly
drier air aloft is expected to diminish shower and thunderstorm
chances to near ~20% or less for the weekend through Independence
Day.

DML

MARINE...
Easterly winds will shift more southeasterly tonight as high
pressure ridges westward along the Gulf coast. A disturbance aloft
and deep tropical moisture over the area will result in scattered
to numerous showers and thunderstorms the next few days. Winds
and seas will be locally higher near thunderstorms. By the weekend,
high pressure and drier air aloft is expected to limit shower and
thunderstorm activity, with a light to moderate onshore flow
continuing.
