Short term (today through Wednesday)
Surface high has built into south central texas early this morning
in the wake of the cold front pushing the deeper moisture up against
the serranias del burro. This is where it will reside in the short
term with any rain over those mountains. The surface ridge eases off
to the east with lower level moisture only slowly spreading back over
our area late tonight into Wednesday. Meanwhile, upper level ridging
moves east over our area. Temperatures for today through Wednesday
will not be as warm as Sunday into Monday, however, they will still
be near to slightly above normal.

Long term (Wednesday night through Monday)
Moisture gradually increases Thursday into Friday. Cannot rule out
a few isolated showers or patchy drizzle Friday morning due to a
weak impulse in the flow aloft. A shortwave rotating around a deep
upper level low centered over hudson bay sends a cold front across
our area on Saturday. Moisture convergence along and upward forcing
by the front should generate isolated to scattered showers with some
instability for isolated thunderstorms. After that the models are in
two camps with regards to the pattern aloft and moisture depth with a
lack of consistency. All models weaken a deep upper low currently
well off the west coast as it moves onshore, then redevelop it near
the four corners region this weekend. By Monday, the GFS tracks it
east across the central rockies into the central plains while the
ecmwf gem track southeast to the new mexico chihuahua region, then
east across texas. The GFS allows southerly 850 mb flow to return
bringing much deeper moisture and stronger upward forcing to generate
much higher qpf. The ECMWF gem keep the deeper moisture over the
gulf with a northeasterly 850 mb flow with much lower qpf. Have gone
with compromise between the two camps. Expect isolated to scattered
showers Saturday night into Sunday with weak elevated instability
possibly allowing for a thunderstorm or two. The showers and any
storms end from west to east Sunday night into Monday. Have trended
cooler with the temperatures post frontal, however, there is some
uncertainty. Deeper moisture as noted by the GFS would minimize the
influence a stronger Sun angle for this time of year keeping it
cooler, while the drier ECMWF gem would allow for that Sun to modify
the airmass keeping it warmer. Have gone with a blended forecast for
temperatures.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
