Area Forecast Discussion
National Weather Service New Orleans LA
356 PM CDT Mon Mar 18 2019

.DISCUSSION...Overall it was a very quiet day today and the forecast
will remain quiet through the week, probably the quietest forecast
we have had in quite some time. Broken to overcast cirrus blanketed
the entire area and this helped keep highs a tad cooler than
previously thought.

A weak reinforcing cold front will move through tonight but this
will have little impact on the region other than lowering the
dewpoints some. Zonal flow will remain overhead through at least
Wednesday before a strong s/w drops south through the Plains and
across the Mid and Lower MS Valleys Wednesday night. This push
through the region but we will remain rain free as moisture will not
return ahead of it. This system will send another wind shift through
the area but really difficult to call it a cold front as temperatures
will not drop behind it.

Heading into Friday and the beginning of the weekend we will see
temperatures climb. Ridging will begin to push across the area and
LL temps will jump up to around 11-12C Friday and up to 14C
Saturday. This will lead to highs back into the mid 70s. Moisture
will finally begin to increase just ahead of the next system to
begin to impact the region. Overall the rain chances aren't great
Sunday but we will likely see a few showers and maybe a rumble of
thunder late Sunday as the ridge axis moves east and mid lvl hghts
begin to fall a little. The risk for showers and thunderstorms may
begin to increase early next week as the next s/w actually pushes
through the Lower MS Valley. /CAB/

.AVIATION...VFR conditions prevail at all area airports. Higher
ceilings and higher visibilities will persist throughout the day as
high pressure enters the forecast area. /MSW/

&&

.MARINE...We still have the presence of a strong pressure gradient
across the coastal waters. High pressure is building over much of
the eastern CONUS while relatively low pressure remains in place
across the western Caribbean and the Yucatan. This will continue to
lead to strong northeast winds over the open waters through tonight
and possibly through a good portion of tomorrow. Have extended the
SCY through 12z tomorrow and let the overnight shift look at things
again to see if it needs to be extended into the day tomorrow.
Pressure gradient finally relaxes some but northeast winds through
Wednesday with the wind field breaking down Wednesday night. Another
weak front moves through overnight Wednesday and will lead to
moderate offshore winds redeveloping but with no real CAA not
anticipating any SCY's needed. Offshore flow should remain in
place through Friday morning. /CAB/
