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 553 AM CST Sun Jan 19 2020
AVIATION. /12Z TAFS/ Mostly clear skies will persist through 00Z Monday with vfr skies expected to continue through the next 30 hours. Look for moderate northery winds today with a few late morning gusts over 20 knots. Mostly light winds are expected tonight into Monday.
PREV DISCUSSION. /ISSUED 326 AM CST Sun Jan 19 2020/
SHORT TERM (Today through Monday) . Wind gusts are becoming less common early this morning, but a few gusts should reappear around 15Z when morning mixing takes place. Otherwise, a steady north breeze at around 10 mph should maintain cold air advection and prevent most of the area from seeing 60 degrees for a high temp despite mostly sunny skies.
A layer of mid level clouds begins to push across West TX this evening as falling heights over the Pacific coast cuts eastward into the ridge over TX. The ridge is nudged east late Monday, and the mid-level clouds gradually take over South-Central TX and begin to dampen diurnal impacts on temps. The early evening should see rapid drops in temperatures, but the pre-dawn temperature drops could level off to near steady as the clouds increase over western counties. Will still plan on good cooling over the Eastern Hill Country and Central TX around Austin with protected valleys probably receiving freeze for Tuesday morning. Highs for Monday should be able to reach near or above those of today, but if a solid deck of mid- level clouds forms, the Monday max temps may need to be revised downward.
LONG TERM (Monday Night through Saturday) . Dry conditions will prevail across the region at the beginning of the long term forecast. After a chilly start in the mid 30s to low 40s Tuesday morning, highs Tuesday will rise into the mid 50s to lower 60s during the afternoon. Rain chances begin to increase Tuesday as a leading shortwave trough ahead of an approaching Pacific trough arrives from the west.
Backed surface flow will limit low level moisture with precipitable water values remaining around or under one inch for most of the region, but very rapid height falls (40 to 80 meters over a 12 hour period) with the lead shortwave will provide more than sufficient lift for precipitation to occur Tuesday evening within the mid- levels of the atmosphere. Forecast soundings show top-down moistening occurring through the overnight hours Tuesday and into Wednesday morning, allowing rain to reach the surface as it spreads west to east across the region. Modest veering of the low level wind profile during the day Wednesday will promote morning lows in the 40s to low 50s into the mid 50s to mid 60s during the afternoon.
Lapse rates steepening to about 6-6.5 C/km with the arrival of the main upper trough may allow for some isolated embedded thunderstorms within a larger shield of rain across the region Wednesday night and Thursday. Medium range guidance begins to diverge with the evolution of the main trough on Thursday as it closes off over the Ozarks, with the European offering a deeper, more progressive solution and the GFS offering a slower translation of the system. This is affecting the timing of a late week cold front associated with the low as well as rain chances for Thursday and Friday as the slower solutions keep rain lingering east of Highway 281 into Friday morning. Have opted for a blend of model solutions given the forecast variability for Thursday and Friday. This will keep highs in the 60s and result in rain chances ending from west to east early Friday morning as the closed low ejects east. Expect generally dry conditions with highs in the low to mid 60s.

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.
