Sounding discussion
The upper air release this evening was routine with no problems
encountered. The 00z sounding depicted a strong frontal inversion
below 900 mb. A layer of drier air was present above the inversion
up to about 600 mb. Above that, the profile was moist throughout
the remainder of the mid levels. The precipitable water value was
1.14 inches. Moderate north winds were observed below the frontal
inversion while west-southwest to southwest winds prevailed
throughout the remainder of the sounding. 11

synopsis...

cold front well to the south and east with surface high pressure
over the great plains. Upper low currently near the dallas-fort
worth area. Shield of light rain primarily east of a slidell to
houma line. Temperatures range from the upper 30s northwest to
lower 50s southeast at 3 pm. Wind chill values are already in the
30s northwest of a houma to gulfport line.

Short term...

upper low will be slow to move northeastward, only reaching west
tennessee by Thursday morning, and the appalachians Friday
morning. Likely to be late in the day Wednesday before skies clear
across most of the area. This will preclude a freeze for much of
the area tonight, with the exception of possibly wilkinson county
mississippi, where temperatures could briefly touch freezing
around sunrise. However, wind chill factors will be in the 30s for
much of the area, which is a decision point for some local
governments to open warming centers for those with sheltering
issues.

Have opted for a freeze watch for Wednesday night Thursday morning
for much the area with the exception of those areas immediately
south of lake pontchartrain and the lower portions of the
louisiana coastal parishes. In those areas, have issued a special
weather statement to ALERT local concerns to the cold conditions
the next couple nights. Temperatures will remain 20 degrees or
more below normal through tomorrow night before slowly moderating
Thursday into Friday. Still could see portions of the area fall
below freezing Friday morning, but will address that with any
watches or warnings after we see what happens tomorrow night. 35
long term...

surface high pressure will keep dry weather across the area
through the weekend and likely through Monday. A new system could
move out of the southwestern states around Tuesday or Wednesday of
next week, which could affect pre-thanksgiving holiday travel, but
that is beyond the forecast period for now.

Slow moderation in temperatures through the weekend, with
temperatures by Sunday and Monday near seasonal norms for mid-
november. Surprisingly little spread between operational ECMWF gfs
temperature guidance even at the end of the forecast period. 35
aviation...

latest radar mosaic this afternoon continues to illustrate a nearly
stationary area of light rain showers across SE la and coastal ms.

In this area of rain, CIGS have been generally consistently between
080-010, with intervals of 005-008 at times causing lower flight
categories. Outside of this area of rain, terminals to the west
remain overcast and dry. Looking ahead into tonight and through
tomorrow, this shield of light rain will likely not move much. It is
possible that the axis of heavier precipitation presses east into
coastal al and fl, however some models indicate the rain shield
possibly expanding back west slightly tonight. This will likely keep
terminals like hum, msy, new and asd locked in light rain drizzle
all night tonight. Meanwhile, btr and mcb may still be for the most
part dry, with a slight chance of some drizzle early tomorrow
morning. Other than clouds and rain, winds will be slowly
diminishing through the night, with wind directions generally
bearing 330-360 degrees. Klg
marine...

persistent northerly winds in the wake of a passing cold front is
expected through the rest of today through early tomorrow. Latest
marine observations continue to indicate near, to right at gale
force wind gusts across western marine zones gmz550 and gmz570.

Because of this, a gale warning will remain in effect through 6pm
cst this evening. Elsewhere, winds appear slightly lighter with
sustained winds ranging moderate to fresh breeze at times, with
gusts to strong breeze. Fortunately, winds will slightly diminish in
western marine zones after 6pm, and will be replaced with a small
craft advisory currently in place across all marine zones through
6am cst Wednesday morning. Latest blended guidance this afternoon
did indicate the possibility of wind gusts surpassing 34 knots at
times after 6pm, but should be isolated and not a widespread issue.

In addition to winds, dangerous seas within the gale warning may
range 8 to 12 feet, but should slowly diminish into the overnight
hours to around 5 to 7 feet in offshore areas, while much less near
the coastline ranging 1 to 3 feet. Conditions should steadily
improve after Wednesday through Thursday with no notable hazards at
this time. Klg

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
