Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

Area Forecast Discussion National Weather Service Austin/San Antonio TX 648 AM CDT Tue Aug 4 2020
UPDATE. /ADDED SLIGHT POPS CENTRAL/ The last round of NW flow aloft convection is moving mainly down the Hwy 281 corridor this morning. Will trust most of the model accounts that this activity will dissipate later in the morning. Was halfway expecting a random shower or two in the early morning package, just thought the coverage would have been too low to mention at that time.
AVIATION. /12Z TAFS/ Only significant feature for the I-35 TAFs is a few clusters of showers that should dissipate by around 15z no other convection is expected. At DRT, southerly winds are picking up, so the usual 3 line TAFs are to account for the diurnal direction changes. No low clouds are anticipated for any of the TAF locations.
PREV DISCUSSION. /ISSUED 313 AM CDT Tue Aug 4 2020/
SHORT TERM (Today through Wednesday) . After a more thorough coverage of rain over central counties Monday, temps are likely to remain closer to normal for one more day over the I-35 corridor, while western and eastern reaches of the CWA get a head start on a warming trend. GFS and NAM solutions depicted some residual convection in the moisture laden area eastern counties early this morning, but radar and satellite trends don't seem to be picking up on anything happening anytime soon. Convective allowing models show an isolated cell or two over the far eastern counties so will assume the rain chance for today will have progressed east into the HGX forecast area while the mid level anticyclonic flow pattern strengthens eastward into Central TX.
With the H7 ridge directly overhead for Wednesday, the temps should finally go back to the typical early August values of the upper 90s and lower 100s over most of the area. The surface winds for today will again be mostly light, which should keep surface dewpoints from creating much of a heat index boost. Slightly more onshore flow is expected for Wednesday and that should bring low 100s heat index values back for most of South Central TX.
LONG TERM (Wednesday Night through Monday) . The Subtropical Ridge centered over Texas expands over the southern states through early next week. Subsidence under the Ridge and dry air aloft keeps rain out of the forecast for most areas. Mid level flow turns southeasterly advecting in deeper moisture into parts of our area by this weekend. This allows the seabreeze to bring a few showers and thunderstorms into our counties near the Coastal Plains during the late morning into afternoon hours on Saturday and Sunday. High temperatures will remain a few degrees above normal. Afternoon heat index values in the mid to upper 90s Hill Country and 100 to 107 elsewhere can be expected.

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.
