Sounding discussion
No issues with flight this evening that terminated in northern
jackson co ms west of hurley at an altitude of 12932 meters or
20.05 miles.

A pretty dry post-frontal sounding with a bit of a constriction
noted at 850 mb of about 5c depression, but very dry above that
level. Precipitable water has been cut in half since this morning,
now down to 0.63 inches. Winds calm at surface, then w-wsw 30-121
kt entire way up. Peak wind 255 121 kt was found at 42,400 ft.

short term...

the cold front is moving through this afternoon and had some
storms earlier, but mostly just a broken line of showers across
the area. Convection was more persistent offshore. Cool, dry air
is moving in behind the front as a 1030 mb surface high pressure
builds over the central gulf coast for the next few days.

Nighttime lows almost area wide should remain above freezing and
daytime highs will be near 60 through Thursday. Some northern and
interior locations might be near 32 for lows early Wednesday and
Thursday morning.

Long term...

for the end of the week the GFS and ECMWF lost the general
consistency that was observed over the weekend in runs last night
and this morning. The main change is what had been forecast to be a
sharply digging 500 mb trough over the southern plains by Saturday
is much more broad and not as far south in the 0z and 12z GFS today.

The ECMWF trough was similarly broad on the 0z run, but has come
in more south again with the trough on the 12z run. A subtle 500
mb shortwave coming out of baja california and across texas would
kick off a period of southwest flow at mid levels Friday into
Saturday. Onshore flow would develop at the surface with rain
Friday night through Saturday night. A surface low may still form
over the northern gulf by late Saturday, though the new trend is
slightly more offshore and east. The possible development and
position of the low would cause significant differences in actual
conditions... More stratiform rain showers, or heavier
rain storms and windier.

In summary wet weather is still likely this weekend, but just how
heavy the rain and possible storms might be is not yet clear.

Cooler and drier air would then move in Sunday. Right now it looks
like high pressure would finish out the month.

Krautmann
aviation... With the exception of new due to marine fog all
terminals have now moved intoVFR status. New should improve in the
next hour(22z) after the cold front passes. Conditions will be
benign through the remainder of the forecast andVFR conditions
will continue. Cab
marine... Cold front is currently moving through the region and once
it passes what marine fog is out there will clear out. Winds will
shift from westerly to northwesterly and then expected to increase
overnight. Between 3-6z 3-5mb pressure rises over 6 hrs along with
some cold air advection around h85. This will lead to winds
increasing over all of the waters but the open waters should pick up
to 15-20 knots with frequent higher gusts and with that will issue
an scy from 3z-15z tomorrow morning. Will also increase breton and
chandeleur sounds in that while the tidal lakes and ms sound will
just have scs headlines. Winds will relax a little tomorrow however
expect moderate offshore winds to continue through Wednesday and
then could see an increase as high pressure slides in the
southeastern CONUS Wednesday night tightening the pressure gradient
across the region. Cab

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.
