.DISCUSSION...
Precipitation has been widespread through much of the day, but
rainfall rates and accumulations have been manageable in the one
to two inch range and no flooding has been reported anywhere
across the region. The frontal boundary responsible continues to
work its way toward the coast this afternoon with short range
guidance indicating a broad band of showers and thunderstorms
continuing along and south of the I-10 corridor over the next few
hours before becoming more isolated late this evening.

A severe thunderstorm watch, which was issued earlier this
afternoon, remains in effect until 8 pm for Jefferson and Orange
counties as well as Calcasieu and Cameron parishes where better
heating has resulted in more substantial instability. Large hail
is the most likely severe threat although some storms could
produce damaging winds.

The frontal boundary isn't expected to make it too far offshore
before stalling and it's proximity combined with another weak,
upper level disturbance traversing the area beginning early
tomorrow morning will serve as a focus for another round of
widespread showers. The Flash Flood Watch continues until noon
tomorrow as the loss of upper level support should allow
convection to wane during the afternoon.

A second, more progressive cold front is still progged to swing
through the region Saturday and although another round of
convection will accompany the front, it should also be deep enough
to push some of the low level moisture out into the gulf allowing
for drier conditions Sunday through early next week.

.MARINE...
Scattered showers and thunderstorms will continue through early
evening becoming more isolated by late evening, but redeveloping
early Thursday morning. The cold front responsible for the
precipitation will advance through the coastal waters this
evening turning winds offshore as it does so. Precipitation will
remain widespread Friday as an upper level trof swings through the
area and again on Saturday as a second cold front pushes through
the region. Drier conditions will develop Sunday through early
next week.
