short term (today through Thursday)...

a much cooler day will be in store today as the region continues to
feel the effects of yesterday's cold front passage. Highs are
expected to only reach into the 60s, and maybe not even that for the
northernmost areas of the CWA including georgetown and the hill
country. The front also effectively cleansed the region of any
meaningful moisture and other than some low level morning clouds
along the coastal plain, should see plenty of sun.

Winds will be the most notable feature today, mostly in the morning
hours as the pressure gradient is still rather compressed. All
indications (models) agree that this will begin to relax around 18z
today and thus a steady decline of wind speeds will occur through the
afternoon hours. By this evening, mainly light north winds will
remain as a surface high positions itself across central and north-
central texas. Also as a result, a very good radiational cooling set
up will be in store overnight tonight allowing temperatures to
efficiently drop into the 30s across the cwa, with some locations
seeing at or below freezing, mainly in the low lying areas of the
hill country.

Among the things to be thankful for this thanksgiving, one is
certainly the forecast. With building heights and high pressure
continued at the surface, a chilly morning will quickly improve to
highs in the low to mid 70s with light wind and clear skies. So for
those looking to work off the turkey dinner smorgasbord with a walk
around the neighborhood, throwing the football around, or even taking
a nap outside, the conditions will be ideal for such occasions.

Long term (Thursday night through Tuesday)...

a rather benign long term forecast looks to be in store through
weekend and into the early part of next week. The pleasant conditions
continue with dry air, clear skies and mild temperatures. A weak
frontal passage should approach Sunday but likely wont impact
temperatures considerably. The next significant front looks to be on
approach come Tuesday night into Wednesday, which may or may not also
have some showers associated with it. Model discrepancies so exist
with the h5 orientation, evolution, and strength in the
ecmwf GFS canadian so have only included 20 pop for day 7 for the
time being. But due to a rather dry air mass in place by the time the
front arrives, am not too excited for rainfall potential just yet.

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.
