PREV DISCUSSION... /issued 538 AM CDT Wed Jun 5 2019/

DISCUSSION...
Early this morning things were looking a bit gloomy
as a large rain shield of moderate to heavy rain off the
northwest Gulf of Mexico was moving inland across
southeast Texas and Louisiana. Temperatures were in the mid to
upper 70s. The airmass was juiced up for the developing Flash
Flood rains that is inevitable.

A combination of deep tropical moisture plume from south Texas
combined with an upper level trough west of the area will lay the
foundation for excessive heavy rainfall today and Thursday.
Extreme PW's of 2.5-2.6" are now moving into the area and will
stay with us through early Thursday. In fact...HPC has now
increased our areas around the I-10 corridor and southward to the
coast to a High Risk of Excessive Rainfall. That translate to
Flash Flood rains coming today through early Thursday for this
high risk area. Gleaming the new QPF rainfall numbers...south
central Louisiana is now expected to receive 3 to near 7 inches of
rain through Thursday with isolated higher amounts possible.
Further west into southwest Louisiana and southeast Texas...the
news is a bit grim...with expected 5 inches to near 1 foot of rain
possible. Further north of I-10...rainfall amounts are expected
to be 1.5" up to 5 inches. A Flash Flood Watch is in effect today
and Thursday.

A Coastal Flood Advisory is also in effect through early Friday
afternoon as coastal flooding develops especially during high
astronomical tides.

Southwest CONUS trof/low will advance across the south plains
late Thursday into early Friday shunting deeper moisture to the
east of the region with rains tapering off through the day Friday.
Drier weather is on tap for the weekend with the exception of
extreme east part of central and south central Louisiana where
residual moisture and heating keep pops in the forecast. A cool
front moving into the area early Monday drying our the area with
slightly cooler high temperatures for the early part of next week.

MARINE...
A surface trough across south Texas will slowly lift northward
today through late Thursday with abundant tropical moisture moving
into the northern Gulf of Mexico. Widespread showers and
thunderstorms will plaque the gulf waters through Friday with
activity decreasing Friday night into the weekend. Moderate
southerly winds and building seas can be expected through
Thursday. Winds and seas will subside Friday into the the weekend.
