Synopsis
A small window for brief heavy rainfall over lower acadiana during
the early morning hours.

A gradual reduction in rain chances during today into Tuesday will
allow heat values to increase. Heat index readings on Tuesday
could be in the 105f to 110f degree range with the possibility of
a heat advisory for portions of the forecast area.

A cold front is expected to reach the forecast area on Wednesday
with an increase in rain chances. This front is expected to move
through and out into the gulf bringing some slightly cooler night
time temperatures and less humid days through the end of the week.

Discussion
Looking at water vapor imagery, a short wave from the mid
mississippi valley down into northwest louisiana, is moving to the
southeast. Ahead of this system, a feed of deep moisture is noted
from the western gulf of mexico through the lower mississippi
valley. As this short wave continues to move to the east-
southeast, the feed of deep moisture will be pushed east of the
forecast area. Until that happens, there is a small window for
some of the storms that develop over lower acadiana to produce
some high rainfall rates in a short period of time. Therefore,
will allow portions of the flash flood watch from acadia parish to
vermilion parish and points to the east to remain in effect
through 7 am. It is highly likely that the flash flood watch will
be allowed to expire at that time.

As drier air in the mid and upper levels gradually moves in, rain
chances will decrease to more isolated to scattered levels instead
of numerous or widespread.

Water vapor shows a stronger upper level low and short wave
moving across the canadian prairies into the northern plains.

Guidance is in good agreement with this short wave digging down to
the southeast with a large upper level trough developing over the
eastern us. This will help deepen northerly flow over the region
and push a cold front into the forecast area on Wednesday, with
the front continuing through the forecast area and out into the
gulf of mexico by early Thursday.

On Tuesday, with drier air aloft behind a departing upper level
disturbance, and possible compression warming ahead of a cold
front entering the region, and pooling of low level gulf moisture,
oppressive heat has a chance to return to the forecast area.

Afternoon MAX heat index or apparent temperatures are expected to
range from 105f to 110f degrees, so portions of the forecast area
may need to be placed under a heat advisory.

On Wednesday, showers and thunderstorms will again increase as the
cold front approaches and low level moisture convergence should be
enough to get activity going during the day.

Some drier air behind the front will bring a reduction in rain
chances from Thursday through Friday, with slightly cooler night
time temperatures, and less humid days.

Rain chances look to gradually increase over the weekend, as an
easterly wave brings back an increase in deep moisture.

Marine
Weak high pressure will ridge across the northern gulf of mexico
over the next couple of days providing light to occasional
moderate onshore flow. Chances for thunderstorms will be
decreasing as an upper level disturbance moves off to the east.

On late Wednesday, a cold front will move into the coastal waters,
briefly increasing showers and thunderstorms again.

Behind the front by early Thursday, light to occasional moderate
offshore flow will occur with a decrease in showers or
thunderstorms.
