Short term (tonight through Saturday night)
A low latitude upper level low will track east across tx Saturday
into Saturday night. Pacific moisture will stream northeast across
mexico late tonight and arrive at the doorstep of south central texas
by daybreak Saturday. Moisture and instability will thus be mostly
elevated early Saturday, but should rapidly deepen Saturday
afternoon. A cluster of thunderstorms may become embedded in the
broader areas of rain over far east counties Saturday evening as
models develop a coastal trough east of vct. Rain chances should
taper quickly west to east by late Saturday night.

Long term (Sunday through Friday)
No rain is depicted for Sunday and a mostly stable SW flow aloft
will partially dry out the area for Sunday night and allow temps to
return to above normals. Upper troughing to the west continues to
amplify as the eastern half of the forecast area destabilizes again
by Monday. Some light coastal troughing could end up generating a
light overrunning pattern and could see some patchy fog or drizzle as
well; for now am not confident as to when and where. The upper
trough shears NE and moves across mainly N tx Tuesday with a weak
front to dry the air out over our forecast area for Wednesday.

Temperatures should remain near or slightly above normals Tuesday and
Wednesday. Above normal temperatures under a flat zonal pattern
aloft will continue into Thursday, but strong front is expected to
arrive late Thursday night. Deterministic models for Friday indicate
a significant portion of upstream energy to promote a cold rainy day
for Friday into Friday night as the cold air advection pattern
continues into Friday night. This pattern could potentially bring the
ingredients from a winter mix for parts of the area next weekend.

For now will assume an all rain forecast through next Friday night.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
