Short term (today through Tuesday)
Other than some passing clouds this afternoon central texas will see
mostly sunny skies with afternoon high temperatures running about 8
to 10 degrees above normal. Relative humidity values back in central
texas have dropped into the teens across the hill country leading to
elevated fire weather concerns, but winds are and should remain
light through the afternoon and evening hours. The afternoon water
vapor continues to show the low pressure system diving southeast
across the upper midwest and great lakes region embedded in a larger
trough across the eastern u.S. A cutoff low pressure off of baja
california will be the culprit that provides the high clouds later
today. A weak ridge can be seen in the synoptic pattern with the next
weather system approaching the west coast.

A weak cold will slip through south central texas late tonight into
Tuesday morning. Behind the front winds will switch around to the
north and temperatures tomorrow and for the rest of the week will be
about 10 degrees cooler, right around seasonal normals. No
precipitation is expected with the front as conditions at the surface
are far too dry. Northwest flow will continue today through Tuesday
as the large trough continues across the eastern u.S.

Long term (Tuesday night through Sunday)
The two highlights of the long term forecast are a second cold front
on Thursday and what happens with the cutoff low across baja
california. In general though mostly sunny skies are expected with
highs around normal through the weekend, with lows in the 30s and
40s. High pressure which is leading to the sunny skies will shift
eastward for the second half of the week.

The Thursday front will rotate through the large scale trough across
the eastern u.S. It will move through during the day and reinforce
the cooler air across the area, maintaining the seasonal
temperatures. The front will again switch winds out of the north for
Thursday and Friday. Enough southerly flow will be in place to keep
relative humidity values above 30 percent behind the next front.

For days 6 and 7 the two long term models diverge. The ecmwf
dissolves the cutoff low into the zonal flow across texas, keeping
the atmosphere and the precipitation forecast dry. The GFS on the
other hand pulls the cutoff low into the trough ahead of the next
front producing rain over the coastal plains for Sunday thanks to
plentiful gulf moisture pulled ahead of the trough. Have sided with
the drier ECMWF for this forecast package and the weaker southerly
flow keeping south central texas dry through the next 7 days.

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.
