Area Forecast Discussion
National Weather Service Houston/Galveston TX
439 AM CDT Thu May 25 2017

.DISCUSSION...
Cool/quiet conditions across SE TX this morning. As the surface
high moves off to the east...we should see onshore winds return
through this afternoon. Warmer temps expected the next few days
along with increasing moisture levels (as S/SE winds strengthen
in response to a low pressure moving into the Southern Plains).
Highs in the lower 90s with lows in the 70s should prevail.

No real forecast issues are expected for SE TX until the latter
part of the upcoming weekend. The system moving into the South-
ern Plains will help to drag a cold front into the state on Sat
and the boundary should eventually make its way into the north-
ern portions of our CWFA by Sun night. The flattened upper flow
will likely keep the front over the area which will then act as
a focus for wet/active weather for perhaps much of next week.
PWs are progged to around 2" as a series of shortwaves approach
from the west. Extended models have been fairly consistent with
this scenario these last few days, so will continue to keep el-
evated POPS in for this time frame. 41

&&

.MARINE...
Onshore winds will quickly strengthen during the day today as the
pressure gradient tightens in response to developing low pressure in
the lee of the Rockies. A moderate onshore flow will prevail through
the weekend with low pressure over West Texas and high pressure over
the eastern Gulf of Mexico. A SCEC will likely be required at times
through the weekend, with SCA conditions possible overnight tonight
into Friday morning. A weak cold front will approach SE TX Sunday
night but is not forecast to make it off the coast. Lighter onshore
flow is forecast for the beginning of next week. 11

.AVIATION...
VFR conditions are forecast for the taf period. Light and variable
winds will become southerly after sunrise and strengthen throughout
the day. 11
