Area Forecast Discussion
National Weather Service New Orleans LA
409 AM CDT Wed Sep 16 2020

.SHORT TERM...Hurricane Sally will continue to pull further away
from the forecast area today.  Ongoing tropical storm conditions
across the far eastern portions of coastal Mississippi will
gradually improve through the day.  In the wake of this system, a
decent cold front will sweep to the south and bring drier and cooler
conditions to the region.  The front is expected to bring scattered
showers and a few thunderstorms to the area Thursday into Friday as
it sinks south across the CWA.  Temperatures will remain cooler than
average with highs in the upper 80s and lows in the upper 60s and
lower 70s expected.  Dewpoints will also be lower with readings in
the 60s and lower 70s expected.  Overall, a fairly pleasant weather
regime can be expected to take hold tomorrow and remain in place
through Friday.

.LONG TERM...A largely zonal flow pattern will dominate the Gulf
South in the wake of Sally, and this will keep a stalled frontal
boundary in place along the immediate coast.  This front will serve
as a focus for scattered shower and thunderstorm development each
day.  A diurnal cycle of convective development can be expected
mainly along and south of the I-10 corridor each day with convection
firing up offshore in the morning hours and then spreading inland
through the afternoon hours.  To the north of I-10, lower
precipitable water values and a deeper pool of mid-level dry air
further behind the front will keep rain chances at 20 percent or
less through the period.  Temperatures will remain cooler than
average through early next week on the back of deep layer northeast
flow.  Highs should only warm into the lower to middle 80s and
overnight lows will cool into the 60s.  Dewpoints will also be lower
in the upper 50s and lower 60s, and a taste of fall like weather can
be anticipated.

&&

.AVIATION...Winds will gradually decrease through the day at all of
the terminals as Hurricane Sally pulls further inland and further
away from the region.  Ceilings will also gradually improve through
the day, and prevailing VFR conditions are expected at all of the
terminals.

&&

.MARINE...Conditions will slowly improve through the day as
Hurricane Sally moves inland, and expect to see north winds of 10 to
15 knots by tomorrow.  A front will push into the waters on Friday,
and northerly flow should increase to around 15 knots by Friday
night and Saturday.  Further tightening of the pressure gradient
across the northern Gulf by Sunday should increase easterly winds
into small craft advisory range.  As winds increase, seas will rise
from 2 to 4 feet to 4 to 7 feet by Monday.
