Area Forecast Discussion
National Weather Service New Orleans LA
342 AM CST Fri Nov 24 2017

.SHORT TERM...
Northwest flow will continue to keep the forecast area cool and
dry through the weekend. A cold front should move through the
region tomorrow and this will only reinforce the airmass as the
atmosphere lacks the moisture to produce rainfall as the front
moves through. A cold morning across the northshore where
temperatures have flirted with the freezing mark most of the
night. Expect another sunny and cool day for the area and expect
the benign weather to continue through the weekend.

.LONG TERM...
Deep layer ridge will build over the area on Monday and Tuesday.
This strong ridging will keep clear skies in place as the
atmosphere remains dry and stable. Temperatures will moderate as
highs get back closer to the 70s and overnight lows in the 40s.
Guidance still suggests at a chance of some shower across the area
in the Wednesday to Thursday time frame. Guidance is in better
agreement in a solution. Looks like a shortwave will move north of
the area and drive a boundary through the area that could kick off
a few showers Wednesday into Thursday. Then a reinforcing wave
moves through on its heels Friday. This may be the greater chance
of showers and possibly a storm early Friday morning. A blend of
guidance was used for the forecast and will have to continue to
re-evaluate rain chances as the we go through the week. 13/MH

.AVIATION...
VFR through taf cycle.

&&

.MARINE...
Winds will continue to ease through the remainder of the week
becoming light northerly today and variable by Saturday as high
pressure settles across the northern gulf. A reinforcing front will
move through Sunday night into monday and will cause winds to rise
to around 15kt for Monday but this will be short lived as return
flow will become established by Monday night into Tuesday as high
pressure moves east. Southerly winds will slowly rise through next
week. A prefrontal trough or weak front will move to the gulf coast
by Wed ahead of the next strong cold front expected in the area by
the end of next week.
