Aviation [06z TAF issuance]
High pressure will build towards the hill country tonight
allowing for light calm northerly winds. Some high clouds will
continue along the coast but overall no aviation weather concerns
for the next 24 hours.

Prev discussion issued 854 pm cst Mon jan 22 2018
Clear skies with the occasional passing high cloud this evening,
should result in efficient radiational cooling allowing temperatures
to drop 30 to 35 degrees colder than Monday's high temperatures.

Precipitable water values have fallen to 0.20 to 0.30 inches
across the region behind last night's cold front. This drier
airmass in place should allow low temperatures tonight to lower
into the mid-30s for burleson to houston counties and upper 40s
along the coast. Therefore, only changes in tonight's update were
to lower dewpoints and min temperatures slightly, to account for
trends in observations. Northwest winds should also decouple
tonight lowering to less than five mph across SE tx, as surface
high pressure continues to build in from the west.

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.
