.DISCUSSION...
Wx map shows sfc low over SE TX this morning, with fairly strong
south to southeast flow over the coastal waters and areas along
and south of I-10. Radar showing solid strong convection along and
ahead of the low, with rainfall estimates of 1-2" per hour, with
radar estimates of 4-6" over SE TX and extreme SW LA.
The heaviest rainfall rates will likely remain along and south of
I-10 into the coastal waters, but prolonged light to moderate rain
over the remainder of C and SC LA. For this, the Flood Watch will
continue through this afternoon. For SE TX, will hold on to the
Flood Watch a little longer for the light rain still falling, but
may be able to drop it towards daybreak if the current trends
continue.
Marginal risk of severe weather continues along the coastal
parishes of Louisiana for the brief intrusion of the warm sector
portion of the sfc low. Thus far, had no reports of severe
weather, nor have seen anything on radar that approached severe
limits. Cannot rule out the development of stronger updrafts with
brief spin-ups possible within the coastal waters (waterspouts)
possibly making it ashore, along with strong gusty winds
associated with the strong convection near the apex and south of
the sfc low.
Behind the exiting sfc low and upper level shortwave axis will be
strong cold air advection bringing back the much colder and drier
conditions to the region. Our daytime highs in the lower 60s are
occurring now through daybreak across SE TX/SW LA, and will fall
into the 50s once the sfc low moves east. Wrap around clouds
behind the sfc low and upper level shortwave will continue today
into Sunday, gradually clearing from west to east Sunday evening
into Monday morning. Expect the coldest night of this coldsnap on
Tuesday morning with lows in the upper 20s to near 30 north of
I-10, and lower/mid 30s elsewhere.
Gradual warming trend on Wednesday and Thursday as the high slips
east. Another vigorous upper level and sfc low expected to move
north of the region late Thursday afternoon and evening, with
another strong cold front to follow Thursday night into Friday
morning. This system and frontal boundary will bring increased
precipitation chances during this period.

.MARINE...
Onshore winds will continue to strengthen along and ahead of a surface
low pressure system across the Upper Texas and Louisiana coast.
Widespread rain is expected to continue early this morning, diminishing
from west to east over Southeast Texas by daybreak, and over
Southern Louisiana for the remainder of the morning into early
afternoon as the low moves east. Strong offshore flow will develop
behind the low as a strong cold front moves through the coastal
waters, with offshore prevailing through Sunday before diminishing.
For the winds, Small Craft Advisory continues for all 0-60nm
zones, and Small Craft Exercise Caution through 12z Sunday.
