Discussion
Per obs, the latest cold front looks to be just off the coast this
morning. Weak CAA noted in the wake of this boundary thus far, but
the slightly lower dewpoints filtering into the region will likely
have impacts with fire weather concerns this afternoon. Otherwise,
this mild dry weather will prevail another day or so as high pres-
sure remains the in charge.

With the surface high moving further east by tomorrow... The return
of onshore winds will also herald the return of low-level moisture
and warmer temperatures. This SE flow will be strengthening during
the evening overnight (fri night into Sat morning) as the next up-
per trof moves into the southern plains and deepens. While progged
pws are not terribly impressive (1.0-1.3"), there should be enough
to interact with any short-waves (moving in just ahead of the main
system) on Sat to produce isolated scattered activity. The highest
pops will likely range from north to south (given the proximity of
the upper low as it lift out to the ne). Will maintain some lowish
pops for Sun as the onshore flow slightly elevated pws remain over
the area. Daytime heating seabreeze should be the main triggers.

These latest (00z) runs are not quite as aggressive with this next
cold front on mon... But are still indicating FROPA late Mon after-
noon. Rain chances look much lower with its passage, perhaps owing
to the pronounced W SW low-level flow ahead of it early mon. Drier
and slightly cooler weather expected in its wake for tues weds. 41

Marine
Cold front moving through the coastal waters and winds should
increase a little this morning becoming more northeasterly with time
today. A seabreeze will likely develop and alter winds locally along
the icw and bays. Southeasterly flow developing Friday strengthening
into Saturday. Gradual moistening through the weekend and could see
an isolated shower or thunderstorm Saturday around matagorda bay
(less likely for the nearshore waters and galveston bay areas) with
rain chances lingering Sunday through Tuesday morning. A stronger
cold front swings through early Tuesday.

Aviation
Vfr for the area with a narrow scattered mid level deck around 6000-
7000ft shifting southward this morning. Patchy fog around byy lbx
areas this morning should mix out as the north and northeasterly
winds pick up slightly by 13z. Most of the area terminals will see
west or northwest winds becoming northeasterly with time. Weak
seabreeze developing this afternoon to impact gls lbx. Cirrus on the
increase tomorrow morning. Again may see some fog around lbx byy
areas Friday morning.

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.
