Sounding discussion
This evening's sounding was successful with no issues encountered.

Temperature and dew points are significantly lower compared to the
last 12 hours, along with winds shifting indicates cold front.

Additionally, with no instability and negative SRH the severe
weather threat has already well passed by along with the fropa.

Low clouds are still hanging out in the area but the rest of the
column is dry, especially above the lcl. There is still a lot of
room for temps to bottom out from the cold air advection with the
winds starting to turn northerly.

synopsis...

low pressure centered near nashville this afternoon, with a
prefrontal trough squall line near mobile. Actual front appears to
be near a slidell to morgan city line at 3 pm. Dry slot is pushing
the last of of the precipitation out of jackson county and
plaquemines parish. Much colder air is also moving into the area.

Temperatures are in the lower and middle 60s ahead of the front,
but are already in the mid 40s at new roads, and down to 40
already at alexandria.

Short term...

have opted to add st. Charles parish to the wind advisory tonight due
to the trajectory of the cold air across lakes pontchartrain and
maurepas.

Pattern remains progressive, with surface high already east of the
local area Monday morning. Return flow ahead of the next storm
system moving out of the rockies will bring a small chance of rain
to the area on Tuesday.

Once dry slot moves away from the area tonight, cold air clouds
will return, and take a good bit of Sunday morning to depart the
area. Clouds will return late Monday night.

While temperatures are expected to stay just above freezing
tonight south of lake pontchartrain, the strong winds will mean
wind chill values in the teens and 20s area-wide Sunday morning.

With significant outdoor activity going on in both baton rouge and
new orleans tomorrow, people should dress for the much colder
conditions. Areas to the north of lake pontchartrain will drop
near or below freezing overnight, but a hard freeze is not
expected, so no freeze warnings will be issued tonight.

Temperatures will struggle to reach 50 tomorrow. Tomorrow night
may be close to hard freeze conditions across the north half, and
around freezing over the river parishes and outer portions of the
new orleans metro. A close call, but will hold off on warnings for
tomorrow night for now. Monday will see temperatures closer to
normal, but GFS numbers may be a little too aggressive with the
warmup. Generally closer to the met numbers then. Tuesday highs
will probably be near the 70 degree mark, similar to yesterday and
this morning. 35
long term...

track of next system is somewhat further north at midweek next
week than the current system. ECMWF is not quite as aggressive
with secondary low development near the coast on Wednesday and
Thursday as it was yesterday. Rain will be a pretty good bet for
Wednesday into Wednesday night. Instability will be rather weak,
so not playing up thunderstorms at this point. Wednesday highs are
likely to be early in the day as colder and drier air moves into
the area for the end of the week. Could be another system around
the end of next weekend, but still differences in timing. 35
aviation...

MVFR CIGS will overspread the region from the northwest through the
remainder of the afternoon and early evening along with gusty west
to northwest winds. Winds over inland airports will subside
overnight tonight while remaining breezy windy and gusty near the
south shore of lake pontchartrain and coast into Sunday morning.

Conditions will improve toVFR later tonight and Sunday morning at
most airports. 22 td
marine...

strong cold front will continue to sweep through the central gulf
coast region's gulf waters this evening. Strong cold air advection
and building strong high pressure will result in westerly to
northwesterly gales, sustained over 34 knots at times across coastal
waters but mostly in frequent gusts of 35 to 40 knots through 6 am
Sunday. Surface observations indicated winds approaching gale force
near the coast and offshore terrebonne parish as of 3 pm with
sustained gales to the west off the southwest louisiana coast. The
gale warning has been left as is from previous forecast. As high
pressure builds into the region, winds and waves will fall below
small craft advisory criteria Sunday, starting earliest on the tidal
lakes and latest over the eastern southeastern offshore coastal
waters. Have issued the SCA on the back side of the gale warning to
account for this. A lull in winds and seas will be short lived as
the next system and cold front will likely bring a return of
approaching SCA or SCA conditions during much of the Tuesday through
Wednesday night periods. 22 td
