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.



Previous 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 southeast TX, as surface
high pressure continues to build in from the west.
