Sounding discussion
No real major changes to the atmosphere via the sounding this
evening. Still looking at a very dry airmass with precipitable
water values at 0.22 inches. Very dry at all levels in the
sounding with our overnight inversion sitting at around 4200ft.

Prev discussion issued 323 pm cst Tue jan 23 2018
short term...

calm weather continues the next couple days with a 1030 mb surface
high pressure moving west to east right over the central gulf coast
region. Expect daytime highs near 60 under mostly sunny skies. Only
some high cirrus clouds are possible mainly across southern areas
from upper level flow that is slightly southwest in the subtropical
jet. Nighttime lows may dip to near freezing across northern and
inland areas early Wednesday and Thursday morning thanks to ideal
radiational cooling conditions. Patchy frost will be possible across
these areas.

Long term...

southeast onshore flow at the surface begins Friday as the high
moves east. Both the GFS and ECMWF have a 500 mb trough crossing the
rockies Friday, but details remain significantly different. The
ecmwf digs the base of the trough well into the south central us
this weekend, while the GFS keeps the trough much more broad. In
response a surface low will probably develop over the northern gulf
by Saturday night. The ECMWF has this occuring very near the SE la
coast, while the GFS is much further south and east offshore.

While it still looks like a rainy 24 hour period for most of the
area late Friday night through Saturday night, the differences
mentioned would result in mainly either showers or heavier rain
and storms. Current thinking is that the ECMWF solution is more
realistic. The GFS ensemble mean is actually a little slower and
more amplified, like the ecmwf. However, a more specific forecast
is not possible at this time given these uncertainties. Cooler and
drier air would then move in Sunday with high pressure early next
week.

Krautmann
aviation... No issues expected with the 18z TAF package.VFR
conditions will continue through the forecast. Cab
marine... High pressure will continue to build to the east out
of the southern plains. This will lead to winds veering around
slowly from nnw to N to nne through tomorrow night. The pressure
gradient will tighten back up a tad tonight but should keep winds in
the 15-20 knot range so have put scs headlines back up over the open
waters along with the chandeleur and breton sounds. High pressure
will continue to push east through the back half of the week with
winds becoming more easterly and then southeasterly by the end of
the week. The gradient should remain tight enough for moderate to
strong easterly winds by Thursday. By this weekend there is still a
great deal of uncertainty with placement of a gulf low but it looks
like strong onshore flow could begin to develop Friday night and
into the Saturday. Advisories a real possibility again Thursday and
into the weekend. 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.
