short term (tonight through Thursday night)...

upper air analysis this morning showed a deep trough over the middle
of the country with the trough axis across east texas. The upper
level flow was from the northwest. At the surface, high pressure was
building in behind a cold front and winds across our CWA were from
the west-northwest. Dewpoint temperatures were 15 to 20 degrees lower
than 24 hours ago. The upper level trough will move off to the east
and be replaced by a a low amplitude ridge during this period and the
flow will shift to west-southwesterly. The surface high will move off
the coast tonight and winds will turn to the south to southeast
Thursday. After a cool start Thursday morning the period will be dry
with warming temperatures.

Long term (Friday through Wednesday)...

the upper level ridge will slowly erode Friday and Saturday with the
flow becoming zonal by Sunday. Friday and Saturday will continue dry
with warming temperatures. Increasing temperatures and humidity will
drive heat indices above 100 over most of the area south of i-35 hwy
90 and above 105 across the southwestern counties Friday and Saturday
afternoons for a few hours. A frontal boundary will move down from
the northwest reaching our northern border by Sunday morning and
pushing through our CWA by Monday morning. Showers and thunderstorms
will develop ahead of the front and continue as it moves through. The
gfs and ECMWF are showing differences in timing and rainfall amount
with the GFS producing higher amounts. Still both models are showing
what could be a significant event, but the differences have our
confidence low. The front will stall somewhere over south texas and
then a series of upper level short wave troughs will move through the
pattern keeping chances for showers and thunderstorms in the
forecast through the end of the period.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
