Prev discussion... Issued 436 am cst Wed feb 20 2019
short term (today through Thursday)...

a cool morning with low clouds across the eastern two-thirds of the
area and high clouds over the northwest part of the region will be
changing for a different scenario this afternoon. Warmer temperatures
in the mid to upper 60s are expected this afternoon while low clouds
erode with some lingering high clouds mainly across the northwest
portion of south central texas.

Clouds return late tonight into Thursday morning over most areas.

There is a slight chance for showers across the far southeast portion
of the area and the coastal plains around dawn or the Thursday
morning commute. Chances for showers increase and expand to the north
and west to affect areas along and east of interstate 35 on Thursday
afternoon.

Long term (Thursday night through Tuesday)...

by Thursday night into Friday morning, an upper level disturbance is
forecast to move across the area to produce light showers, drizzle
and patchy to areas of fog. As the morning progresses, an upper low level
system is forecast to move across northern mexico and then into west
texas by Saturday morning. In the meantime, ahead of this system,
several short-wave disturbances are expected to move across the area
over the warm sector high humidity area. If the cap erodes with this
added instability, there could be isolated thunderstorms across the
hill country and over areas east of highway 77 on Friday afternoon
and evening.

As the upper low level system approaches the area late Friday night
into Saturday morning, showers and isolated thunderstorms are
possible across most areas and especially along and north of highway
90. A pacific cold front is expected to move from west to east
overnight early Saturday. In the wake of the frontal passage, expect
dry weather and breezy conditions with highs in the upper 60s to mid
70s.

Dry weather continues into Sunday but chances for rain return early
next week for areas along and east of interstate 35.

Fire weather...

due to the breezy conditions and low relative humidity expected in
the wake of the pacific front, elevated to near critical fire weather
conditions are anticipated Saturday afternoon for areas along and
west of interstate 35.

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.
