Area Forecast Discussion
National Weather Service Houston/Galveston TX
844 PM CST Thu Dec 14 2017

.DISCUSSION...
A weak cold front has moved off the coast and high pressure over
eastern CO was slowing pushing south. A large swath of clouds
extended from western Mexico across TX will persist tonight and
much of Friday with maybe some partial clearing from the north
late Friday. Made some minor tweaks to the grids but the current
forecast is in good shape so no significant changes planned.

A vigorous short wave trough heads this way on Saturday and this
feature coupled with high PW air and favorable jet dynamics should
yield a pretty good chance of storms. Depending on how far inland
the surface low tracks will determine if any strong storms can
develop. Strong storms or not, some areas will receive some
healthyDecember rainfall. 43

AVIATION...
The cold front has pushed through all sites except KGLS and will
finally push off the coast in the next hour or so. N to NW winds
are expected in the wake of the front, potentially becoming fairly
breezy for KLBX and KGLS overnight tonight. Some showers will
also be possible right along the coast during the early morning
hours. VFR conditions are expected to prevail through the period.
