Synopsis...broad middle and upper level troughing remains over East
Texas into Louisiana and the western Gulf. This feature gruadually
fills in late Thursday with surface high pressure gruadually
building in this weekend. Moisture will be slow to clear out so
there will be at least a mention of precipitation on Labor Day and into
next week.

&&

Short term...a good chance for rain this evening for most of the
area with the possible exception of Acadiana thanks to the
aforementioned moisture combined with upper level difluence and
the right rear quadrant of the polar jetstreak. The rain looks to
linger late tnite due to short wave energy. The pattern has been
persistent on overnight temperatures...went higher than guidance for the
southern tier where dew points again are running higher than
prognosticated.

Long term...kept likely probability of precipitation especially for the SW zones on
Wednesday with moisture and jet energy continuing. Low end rain
chances Thursday through the extended. A deep western trough and an
open Gulf despite the addition of some low level ridging.
