Area Forecast Discussion
National Weather Service Houston/Galveston TX
300 PM CST Fri Jan 25 2019

.DISCUSSION...
Have been seeing a general/gradual increase in clouds from west to
east today, and this trend is expected to continue for the rest of
the afternoon and on into tonight. Low rain chances come back into
the forecast Saturday through Saturday night with the higher values
in/around the Matagorda Bay area as a weak trough develops along 
the lower/middle Texas coast. As the trough moves eastward, high 
pressure builds into the area and gives us a dry Sunday and Monday
with the warmest temperatures over the next seven days likely 
coming on Monday under strengthening south to southwest winds. 
Models are generally trending just a bit faster with the passage 
of a strong cold front that currently looks like it could be in/ 
around our northern counties around or shortly after sunset Monday
evening and along/off the coast around or shortly after midnight.
Look for colder temperatures to move into the area behind the 
front with morning lows on Tuesday expected to range from the low 
to mid 30s inland to the lower 40s at the coast, and highs across 
much of the area will likely be in the 40s. It will turn breezy/ 
windy behind the front too, and some wind advisories might be 
needed. High pressure builds quickly into the area during the day
on Tuesday resulting in relaxing winds. Morning lows below freezing
look likely on Wednesday, generally along/north of a line from 
Brenham to The Woodlands to Liberty, and with light/calm winds 
they could get as low as the upper 20s at our normal cold locations.
Models are still showing some differences for the second half of 
the week, so for now will continue to keep some low rain chances 
along with near normal temperatures in the Thursday/Friday forecast.
