Update
Outflow boundaries from a convective complex that moved across south
texas earlier this morning has helped to initiate scattered to
numerous showers and thunderstorms mainly east of the i-35 corridor
this morning. Based on current radar trends, we have increased rain
chances across the coastal plains into the i-35 corridor for the
remainder of this morning. Some locally heavy rainfall is possible
across these areas, especially where multiple cells move over the
same region.

aviation... 12z update
i-35 terminals are jumping around from MVFR toVFR. Will begin this
forecast period with all locationsVFR. Could be a brief period of
MVFR CIGS through 14z. Will continue to have mid and upper level
clouds as MCS shifts easts off the coast and into the gulf of mexico.

Few pockets of -ra continue in the Sat area and areas east of i-35.

All the light precipitation will be out of the area by 13z. Then the
question shifts to convection this afternoon. Should see isolated to
scattered shra tsra mid to late afternoon. Coverage will not be
nearly as widespread as Sunday afternoon. Winds will be variable
this morning then become easterly after 15z-17z at speeds of 7-10
knots. Overnight expect low clouds to return with MVFR cigs
developing around 09z-10z across the east and around 11z-12z at kdrt.

Winds will continue out of the east less than 10 knots.

short term (today through Tuesday)...

the mesoscale convective system and cold front boundary that brought
severe storms and heavy rain across the area Sunday afternoon and
evening are about to meet across the northwest gulf waters. In the
wake of these convective weather systems, isolated light showers
continue to affect the southern counties of south central texas early
this morning.

Most hires models suggest a lull from precipitation across much of
the area through late this morning. Scattered showers and isolated
thunderstorms are expected to develop across the hill country this
afternoon. Some areas may get lucky with no shower or thunderstorm
activity this afternoon or evening while others could get an
isolated shower or several rounds of showers and thunderstorms.

For this evening into Tuesday morning, there is a slight chance for
rain across most of the area with overnight temperatures in the lower
60s across the hill country to upper 60s elsewhere.

Long term (Tuesday night through Sunday)...

chances for rain are anticipated to increase late Tuesday night into Wednesday
across the rio grande as another short-wave moves across the area.

Showers and isolated thunderstorms are expected to expand in coverage
Wednesday afternoon and evening as instability grows. Area forecast
soundings suggest elevated CAPE values with pwats in 1.7 to 1.8
range, which could result in an episode of strong to marginal severe
thunderstorm development in addition of heavy rain.

The wet pattern continues through the upcoming week as several upper
level disturbances move across the area. Next cold front and
significant weather day looks to be Sunday into Monday of next week.

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.
