Cf is now south of all the taf sites and extends from Matagorda
Bay to 30 nm south of gls. Expect 5-10 knots northerly winds to
continue through tomorrow. The main issue will be ceiling heights
late tonight and Sat morning. MVFR ceilings currently near a cxo
to uts line will gradually push S/SW. A fairly ragged edge
to the cloud cover exists with some variability in ceiling height
as well. Generally expect ceilings to vary between 2-3kft tonight
and early tomorrow at inland sites. 33

frontal boundary has now pushed past Galveston and is making its
way off the coast. North wind behind the front has allowed
slightly lower dew point air to advect into the region. This means
a cooler night than usual for this time of year. Tomorrow afternoon
highs will also be cooler than normal thanks to lower 850
temperatures. In our northern areas 850 temperatures around 16c are
forecasted with 850 temperatures near 18c towards our
southwestern zones. This will translate to temperatures in the upper 80s
to near 90 for most of the area with lower 90s in our southwestern
areas. Have adjusted maximum temperature grids to match above. Precipitation
chances look low tomorrow as much drier precipitable water air filters into the
area. Yesterday observed values were around 2.2" with values
tomorrow forecasted to fall near 1.50". GPS met site already
showing Houston precipitable water value down to 1.6" at this hour. 23
