Update
See below for the 00z aviation discussion...

Aviation
CurrentlyVFR at all terminals with breezy southeasterly winds.

Thunderstorms fired this afternoon west of drt across the big bend
and into northern mexico, but those storms have died before coming
anywhere close to drt. Tonight should be similar to last night and
the night before it, with MVFR CIGS developing at aus Sat ssf around
4z to 5z this late evening and at drt by around 6z early Saturday
morning. A few streamer showers will be possible early Saturday
morning through late morning, especially in the vicinity of Sat and
ssf. CIGS should improve toVFR once again by mid to late Saturday
morning. Winds throughout the TAF period will remain out of the
southeast and elevated, with sustained winds in the 10 to 15 knot
range. Winds overnight tonight should not be quite as strong as last
night, as the low level jet is expected to be weaker. Gusts up to 25
knots will return by late Saturday morning and should continue
through the afternoon hours.

short term (tonight through Saturday night)...

persistent southeast flow at the surface has kept elevated moisture
over south central texas. For this reason, a stray streamer shower
late this afternoon for the eastern half of the area can't be ruled
out. Convection is expected to develop in the trans pecos and burro
mountains early this evening and push east. These storms have the
possibility of becoming strong to severe but chances that convection
will make it into val verde county are low. MAX temps will be a
degree or two above climo norms with overnight lows 5 degrees above
normal. Overnight temps will have trouble cooling off with winds
remaining elevated due to the tight pressure gradient between the
ridge just to our east and an upper level low to our northwest.

Long term (Sunday through Friday)...

an amplified pattern remains over the us with a ridge anchored in
the southeastern CONUS and a longwave trough just west of the state.

Expect to stay dry for most of the period with the ridge keeping most
of the weather making disturbances in the texas panhandle. Longwave
trough to the west is reinforced by an upper level low that digs
south along the west coast early Sunday. As this feature begins to
work its way east and just north of the state, the ridge is
suppressed slightly. This weakening of the ridge over our area may be
enough to bring in some rain along a front for Thursday. However
both GFS and euro have this line of convection stalling over the
central part of the state and into the mississippi valley, so main
concern for rain chances will be how far this activity can work its
way south.

In the wake of this system, zonal flow aloft will be in place for the
end of the period with embedded features making their way over the
state. Have just kept 20 pops in for this period due to uncertainty
and placement of impulses.

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.
