Area Forecast Discussion
National Weather Service Houston/Galveston TX
314 PM CDT Wed Apr 25 2018

.DISCUSSION...
A cold front will push through the area this afternoon into
tonight, with showers and thunderstorms developing along and
behind the line this evening. Hi-res guidance is indicating that
the cluster of storms currently near San Antonio will push
southeastward towards Matagorda Bay later this evening, so the
highest PoPs for today are focused down there as the coverage
elsewhere looks to be more broken. Offshore winds and dry
conditions are expected in the wake of the front starting tonight.
Another weak front will push through on Friday, but most people
probably won`t even notice. Beautiful and warm weather is expected
Thursday through the weekend, with onshore flow returning
Saturday.

Upper-level ridging moves off to the east Sunday night, setting up
southwesterly flow aloft. Several shortwaves rotate across the
area early next week, bringing slight chances for showers and
thunderstorms back into the forecast. Coverage (if any) will
largely depend on the timing of the shortwaves and how much
moisture return we can get prior to their arrival.

.MARINE...
Cool front will be making its way off the coast probably sometime
between 10pm-1am. May see some iso/sct shra along and behind the
boundary with better coverage near the Matagorda Bay area. Hoisted
the caution flags overnight as offshore winds increase. It should be
noted however that some of the hires model runs have been
intermittently advertising some sustained 20-25kt winds lasting for
about 3 hours after the windshift. Will let the next shift
reevaluate trends and possible upgrade to advisory flags. Winds/seas
will subside Thurs afternoon. Look for a weak reinforcing front
Friday morning. Light winds and low seas will prevail over the
weekend with high pres in control. Onshore winds will increase and
seas build early next week.
