Short term (tonight through Thursday night)
A much quieter forecast is expected for the short term period
compared to the last several days. With the upper level ridge axis
shifting east and over the area as well as a low to mid level low
pressure area over the coast of texas, lifting and moisture are
lacking for much convection this afternoon. Some stray isolated cells
from near the coast may drift northwest into the southeast zones late
this afternoon but occasional cloud to ground lightning and briefly
heavy rain are the only concerns, if anything reaches that area.

Similar set up again tomorrow with very isolated chances for
showers storms in the southeast zones. The upper ridge continues to
plant itself over the region with temperatures warming into the mid
90s and heat indices creeping into the triple digits.

Long term (Friday through Wednesday)
Heat indices look to peak Friday with many locations coming very
close to heat advisory criteria, basically everywhere not on the
edwards plateau. Not much change is expected in the synoptic pattern
over the weekend and into early next week. By the fourth of july,
highs will be in the mid to upper 90s along the i-35 corridor
southwest to the rio grande.

The upper ridge will weaken slightly mid week next week, perhaps
enough to re-introduce isolated pop chances in the southeast, but
models currently keep chances less than 20%. Thus for the next 7
days, the focus for potential weather hazards will be primarily heat.

With many folks likely to be exposing themselves to extended periods
in the heat over the weekend and through the holiday, extra
precautions should be taken for staying hydrated, protection from the
sun (shade, protective clothing, and not over-exerting).

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.
