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

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
