national weather service houston/galveston tx
1244 pm cdt Tue apr 25 2017

Aviation
Ceilings are trending upward intoVFR territory and should
continue to do so. Main issue for the remainder of the daylight
hours will be gusty south winds. Anticipate low stratus to redevelop
overnight, but winds will likely remain gusty for a good part of
the night as the low level jet increases and mixes. Dryline &
cold front move into the region Wednesday afternoon. Can't rule
out some streamer showers in advance, but it appears a stout cap
will limit overall TSTM chances at the majority of our TAF sites.

Better chances should be situated toward NE tx. 47

Prev discussion /issued 931 am cdt Tue apr 25 2017/
the previous forecast appears to be on track, and no major
changes were made. Breezy and warm conditions are expected today

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.
