327 am cst Wed jan 24 2018

Short term
Moisture will begin to surge north over texas Thursday ahead of
the next developing cold front. This moisture surge will
eventually work its way west over our area by Friday with a few
showers breaking out late in the day Friday. Rainfall will
steadily increase in amount and areal coverage through Saturday
when a sfc low develops over the northern gulf or at the coast.

Heavy rainfall will move east with the low and should be east of
the area by Sunday. A cold front will then move through later in
the day on Sunday with a few showers but will be mostly moisture
starved.

Resolving the location of the sfc low's developent will
continue to be tough for models, but a more agreeable solution
between models looks to occur by Thursday's runs. Regardless, the
sfc low looks to eventually become a frontal low and these
normally run along the strongest thermal gradient which would be
along the coast during its weaker developing stage until the low
can advect this thermal gradient northward and start moving more
northeast.

Long term
High pressure settles back into the area for most of next week.

But by the end of the week some very interesting features are
beginning to show up which are looking to make things interesting.

This is a bit outside the temporal range of this fcast for now.

Aviation
Vfr conditions expected at all terminals throughout the forecast
period.

Marine
Winds are starting to ramp up across the coastal waters with many
observations in the 20 knot range. There will likely be a prolonged
period of increased winds over the coastal waters and with that will
raise scy headlines at 12z. This will include the inner and outer
waters and chandeleur sound and breton sound. High pressure will
continue to move east tomorrow and Friday with winds becoming more
easterly and then southeasterly by the end of the week. The gradient
should remain tight enough for moderate to strong winds and the
likelihood of extended headlines through the weekend.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
