short term (today through Wednesday night)...

an upper level impulse overhead will be east of our area by midday.

Lower to mid level ridge builds in to continue the ongoing clearing
trend with mostly sunny skies resulting in warmer temperatures for
all areas today. This will be short-lived as a compact upper level
shortwave currently off the northern baja california coast moves
across central texas Wednesday and Wednesday night. Clouds return
tonight due to moisture advection. Upward forcing leads to slight
chances of showers Wednesday morning with stronger forcing from noon
to midnight. However, significant moisture return is not expected as
pws peak just above an inch and have maintained the low chances for
showers. Showers end by late evening or early overnight as the
trough moves east of our area. Rainfall amounts of less than 1 4 inch
are expected. Clouds and rain keep temperatures cooler again on
Wednesday.

Long term (Thursday through Monday)...

thanksgiving looks mostly cloudy with below normal temperatures,
though warmer than Wednesday due to a few more peaks of sunshine. On
Friday, an upper level trough currently off the west coast near 140w
moves rapidly across the southern plains along with a pacific front.

A brief period of upward forcing results in low chances of showers
during the morning hours. Weak elevated instability may generate an
isolated thunderstorm. In the wake of the pacific frontal passage,
southwest to west winds result in warmer, above normal, temperatures
for Friday and Saturday. An upper level trough moving across the
central and northern plains forces a canadian cold front across our
area Saturday night into early Sunday morning. Lack of moisture
convergence along the front keeps pops out of the forecast. A strong
surface pressure gradient along with mixing of stronger winds aloft
should make for a breezy day on Sunday. Temperatures drop back to
below normal on Sunday, then more so on Monday.

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.
