Area Forecast Discussion
National Weather Service Houston/Galveston TX
930 PM CST Fri Jan 11 2019

Line of showers approaching the region from the west should push
through the area overnight as forecast. Only changes for the 
evening update were to nudge POPs up in the western zones in the 
next couple hours as the leading edge of precip may arrive a touch
earlier than what was in the grids. Otherwise, just insignificant
tweaks to match observations. 47

AVIATION [00Z TAF Issuance]... 
While all terminals are VFR at issuance time, expect that MVFR 
ceilings will emerge this evening with a line of broken showers 
(along with some isolated lightning) entering the area just before
midnight, and moving coastward through the late night hours. Just
behind the line, look for ceilings to fall further to around or 
below the IFR threshold before a quick clearing late in the 

PREV DISCUSSION /Issued 342 PM CST Fri Jan 11 2019/...
Clouds have begun to fill in across central and eastern parts of 
the area this afternoon. Expect the rest of the area to fill in 
across the rest of our area this afternoon, this evening and 
overnight. The bulk of rain (maybe some embedded thunderstorms 
eventually forming too) is still expected mainly tonight through 
early tomorrow morning as the next system moves into and through 
the region. Rapid clearing can be expected from west to east as 
the day progresses (rains will be ending in the morning). Rainfall
totals are still expected to be on the low side with this system 
with most spots getting around 1/4 to 1/2 inch and isolated 
locations maybe approaching an inch or above. It will be cooling 
back down beginning Saturday night as high pressure builds in from
the north and northwest, and these cooler temperatures (lows in 
the 30s/40s and highs in the 50s) are expected to persist into 
Tuesday. Coastal trough development might end up bringing periods 
of rain back into our area beginning on Tuesday (none to low 
chances north and higher chances near the coast and offshore) with
activity maybe continuing on and off through the end of the week.
Look for gradually warming temperatures (lows in the 40s/50s and 
highs in the 60s/70s) Tuesday night through the end of the week. 

Light onshore flow will turn out of the NW behind a cold front which 
should push into the nearshore waters by Saturday morning. Small 
craft should exercise caution overnight tonight leading up to the 
passage of the front as the pressure gradient tightens over the 
region. Showers and isolated thunderstorms will be possible over the 
bays and Gulf waters early Saturday morning and into the early 
afternoon hours. Moderate northwesterly winds behind the front will 
be borderline SCEC/SCA criteria early Sunday and into the afternoon 
hours. Onshore winds are expected to return by mid week.
