Area Forecast Discussion
National Weather Service Houston/Galveston TX
924 PM CST Tue Mar 6 2018

.DISCUSSION...
Forecast looks on track for quiet and cool weather for the next
couple of days as high pressure builds into the region. No need
to make any major changes to the package on the evening update.

.PREV DISCUSSION... /ISSUED 541 PM CST Tue Mar 6 2018/

AVIATION...
VFR. A reinforcing dry cold front latter this evening will
briefly strengthen these ongoing northerlies. Cirrus to pass
across from the west. 31

PREV DISCUSSION... /ISSUED 358 PM CST Tue Mar 6 2018/

DISCUSSION...
Mostly sunny, warm and very dry (RH in the teens) across the area
today. Look for a decent temperature drop overnight with caa continuing
as high pressure makes its way further south into the region.
Mostly sunny, dry but cooler conditions should prevail Wednesday
with ridging in control.

Onshore flow resumes Thursday as the high moves off to the east
and lee side pressures fall. It probably won`t be until Friday
until we see a noticeable return of low level moisture, but do
expect some variable high cloudiness before that time as Pacific
moisture streams over the top of a mid level ridge extending from
Mexico into the southwestern United States.

Low precip chances are introduced back into the fcst on Saturday,
more than likely in the form of streamer or waa-type shra. By late
Saturday the llvl flow veers more to the sw which should take the
better moisture axis off to the east (and likely provide a strengthening
cap) ahead of the next cold front penciled in for late Sunday.
Have kept with the silent 10% POPs with the frontal passage for
the reasons described above. This front looks like a legitimate
front for this time of year. Spring Break may start off with temps
running slightly below normal. 47

MARINE...
As the cold front continues to move further into the Gulf, winds
have settled down over the bays/nearshore waters this afternoon.
However...we are still having issues with elevated winds/seas across
the offshore waters and have kept the Small Craft Advisory going
for these locations through early tomorrow. While we will likely
get a brief break this evening, these elevated winds/seas should
be returning tonight/overnight with the passage of a secondary
cold front. This colder airmass moving over the warm(ing) coastal
waters should make for very strong/gusty north winds for this
timeframe. This SCA could be expanded to include all of the
coastal waters with the next package.

Light onshore winds to return Thu as the high shifts east of the
region. Wind speeds should be slowly strengthening on Fri/Sat as
pressures fall over the southern plains (with the next system
beginning to develop). The next cold front is progged to move
into the coastal waters perhaps next Sun. 41
