Aviation
Storms occurring ahead of the cold front will be moving across the
terminals from 00z at kuts to about 04-05z at kgls. A strong
thunderstorm should be east of kcll by 00z; however, more showers
were developing to the west of the site. There is a slight
possibility of a strong or severe storm with gusts in excess of
50 knots and large hail making its way through the sites between
kcxo and khou between 00z and 02z.

Expect the storms to be off the coast by 06z.VFR conditions are
then expected. Breezy winds are expected to then develop after 15z
Wednesday.

discussion...

surface analysis as of 1 pm cdt showed an approaching cold front
stretching from del rio to waco towards shreveport, with a weak
prefrontal wind shift entering portions of the brazos valley.

Regional radar mosaic this afternoon shows a few cells developing
along and behind the front as it continues to push towards the
southeast. With rap guidance instability increasing ahead of the
approaching boundary and lift overspreading the region from a
passing 90 knot upper jet, expect the severe weather threat to
increase over the next few hours for southeast texas as scattered
thunderstorms continue to develop along the front. Expect the
front to clear the brazos valley late this afternoon, reaching the
houston metro mid-evening, and clearing the coast around midnight
tonight. Steep mid-level lapse rates will result in a large hail
and damaging wind threat (especially if any storms bow out) as the
front progresses southward.

A few showers may linger behind the front tonight before
dissipating as drier air moves into the region, with clearing
clouds and cold air advection behind the front resulting in
cool overnight low temperatures in the mid 50s to mid 60s. Dry
weather will continue through the rest of the week with high
temperatures gradually warming into into the low 90s by Friday as
shortwave ridging translates across the region. Northerly winds
will gradually swing around to the south by Thursday as surface
high pressure slides off to the east, allowing moisture to
gradually return by the beginning of the weekend. A cold front
looks to slide into texas by the beginning of the weekend and
stall at the beginning of next week as an upper low reaches the
great lakes. Will have to keep an eye on the Monday Tuesday
portion of the forecast next week as disturbances overriding this
stalled boundary look to result in a very wet period for the
region.

will return early Thursday and quickly strengthen during the day.

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.
