Area Forecast Discussion National Weather Service Houston/Galveston TX 1135 PM CDT Sat Jul 11 2020

AVIATION. VFR conditions expected for much of the night but could get a mix of MVFR/IFR cigs after 09z. Models are certainly less bullish with cloud development but persistence would suggest a BKN deck by sunrise over mainly the western TAF sites. Added a BKN250 deck as some cirrus blow off from convection over North Texas sinks southward. VFR conditions expected areawide after 15z. 43

PREV DISCUSSION . /ISSUED 336 PM CDT Sat Jul 11 2020/

SHORT TERM [Tonight through Tomorrow/Sunday] .

Heat Advisory re-issued for tomorrow.

Not a lot of changes to the forecast as this hot/dry pattern con- tinues into tomorrow. Light southwesterly low-level flow combined with elevated 85h temps and ridging aloft will all help keep this muggy weather in place. Brief/patchy low clouds are possible over northern portions of the CWA overnight, but should mix out by mid to late tomorrow morning . with mostly sunny skies prevailing the rest of the day. As such did go ahead and re-up the Heat Advisory for tomorrow. 41

LONG TERM [Sunday Night through Saturday] .

Little change has been made to the long term forecast. Mid/upper level high pressure initially centered off to our west will expand and work its way off to the central parts of the nation. At the surface, onshore winds will persist with high pressure generally situated off to our east. For a majority of the area, the return of any rains will likely hold off until the mid/upper level high gets far enough off to our north to allow for some deeper moisture to work its was westward across the Gulf of Mexico and towards our area. This might hold off until the end of the week or possibly not until next weekend. The heat will continue to remain the main weather feature across the area for much of the upcoming week with heat index values expected to peak in a 105 to 110 range. Heat Advisories might be needed. 42

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.
