Area Forecast Discussion
National Weather Service Brownsville TX
252 PM CDT Tue Apr 4 2017

.SHORT TERM (Tonight through Wednesday Night): 500mb low across
northeast New Mexico and Texas panhandle this afternoon will move
eastward across the southern plains tonight and open up as a 500mb
trough across the midwest United States and east TX Wed afternoon.
This will bring a cold front through the CWA Wed morning and surface
high pressure will build into the area Wed afternoon. The pressure
gradient will increase across the lower TX coast Wednesday and wind
advisories will likely be needed for the coastal counties as a
result. Winds will diminish Wed night as surface high pressure
settles over the area. Some patchy fog may develop across the
eastern portions of the CWA tonight as winds become light and
variable ahead of the front moving into south TX.

.LONG TERM (Thursday through Tuesday):It's a quiet start to the period,
with fairly pleasant conditions in place across the Rio Grande
Valley and Deep South Texas. Near normal temperatures expected
along with comfortable dewpoints on Thursday. Surface high
pressure centered over central Texas Thursday shifts east over the
western Gulf of Mexico during the day and Thursday night,
resulting in winds shifting back to the southeast Thursday night.
With the return of onshore flow, moisture, winds, and temperatures
increase. On Friday, temperatures remain near normal, with a
slight increase in dewpoints and moderate southeasterly winds.
Pressure gradient tightens Saturday as high pressure over the
northern Gulf of Mexico interacts with lower pressure over the
Plains, resulting in breezy conditions Saturday and Sunday. Model
guidance has continued a slightly downward trend of peak sustained
winds on Sunday across the coastal counties, so have kept winds
below wind advisory levels on Sunday afternoon. Would not be
surprised to see a few brief periods where winds eclipse 25 to 26
knots. Warming trend ensues over the weekend with above normal
temperatures returning for much of the area.

Moving into Monday and Tuesday, a change in the pattern comes in,
with a weak s/w tough moving across the region. The combination of
the trough and increasing low level moisture will lead to a slight
chance of showers and thunderstorms Monday. Model differences
arise going into the Monday night and Tuesday time frame with the
ECWMF trying to push a boundary through the region and the GFS
being more conservative and keeping it north. Have introduced
slight chance pops in for Tuesday to account for rain chances with
boundary.

&&

.MARINE:(Tonight through Wednesday night): Seas were near 4 feet
with southeast winds near 12 knots at buoy020 this afternoon. Light
south winds will prevail across the coastal waters tonight before a
cold front moves through the lower Texas coast Wed morning. Winds
will shift to the north and increase with gusts to near gale force
likely. Will go ahead and issue a gale watch for the Laguna Madre
and offshore waters Wed morning through early Wed afternoon. Very
strong north winds Wednesday will gradually diminish Wed afternoon
through Wed evening as the pressure gradient gradually weakens
across the lower TX coast as high pressure settles across deep south
TX. Small craft advisories will be needed for all of the coastal
waters Wed afternoon and for the offshore waters Wed night.

Thursday through Sunday: Winds and seas will be on the downswing
Thursday morning in the wake of Wednesday's cold front, but Small
Craft Advisories may still be ongoing Thursday morning for the
offshore Gulf waters. Seas will continue to subside Thursday
afternoon and night as surface high pressure shifts east across
the western Gulf of Mexico. Pressure gradient strengthens going
into Saturday, with SCEC conditions likely Saturday afternoon
across all waters and Small Craft Advisories likely by Saturday
evening for the Gulf waters. Small Craft Advisory conditions are
likely to continue through the day Sunday for all lower Texas
coastal waters.

&&

.FIRE WEATHER...With observed and forecasted fuel dryness across
portions of the CWA...will continue Fire Weather watch for most of
the area late Wed morning through Wed afternoon as a cold front will
move through the Rio Grande valley Wed morning bringing drier air
into the region and strong north winds. This will result in low
relative humidity values and 20ft winds near Red flag warning
criteria Wed afternoon.
