temperatures at 9 am range from the low to mid 30s well inland to around
40 at the coast. Areas of mainly light to occasionally moderate rain
along with a few spots getting some frozen precipitation continue working
their way rapidly off to the east across the area, and a majority of
the activity should be off to our east over the next several hours.

Keeping a eye on some new and much weaker radar echoes popping up to
the south through southwest of the austin-san antonio areas. So far,
no precipitation is showing up on area observations with this activity.

Drier air will eventually work its way into the southeast texas as
the day progresses, and will probably do a couple forecast updates
over the next couple of hours as everything exits the region.

Only some minor grid adjustments were made on the morning update. 42

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
