341 am cdt Sun may 19 2019

Short term (today through Monday)
Patchy fog has developed across portions of south texas this
morning as low level moisture remains trapped beneath the cap with
relatively light winds. Visibilities will improve by mid morning
as we warm up considerably today, especially out west where we
will be several degrees above normal for the middle of may. We
will remain pretty cloudy today as low level moisture increases
across the region. Despite the increased moisture (pwats near
1.5"), we aren't expecting much in the way of precip over the
next couple of days, outside of an isolated shower or two beneath
the cap, as a weak mid level ridge settles in. Onshore flow will
begin to strengthen late tonight into early Monday morning in
response to a deepening low pressure across the western conus. The
tightening pressure gradient will result in very windy conditions
Monday, with wind advisories likely needed as gusts could reach
40+ mph across the brush country and portions of the coastal bend.

The combination of the strong winds and slower moisture return
across the brush country could result in a period of elevated fire
weather concerns Monday afternoon.

Regarding the ongoing coastal flooding concerns, we will soon be
entering high tide along the middle texas coast. Water levels
continue to run about 1.15-1.2 ft above expected with this trend
likely to continue into early next week. Water levels will reach
1-1.3 ft above ground level this morning with water levels being
slow to subside due to persistent onshore flow. The coastal flood
advisory will likely need to be extended through Monday.

As mentioned earlier, temps will warm up into the upper 90s out
west (nearing sps criteria) over the next couple days. Mid to
upper 80s are expected along the coast. Another warm and very
humid night is expected tonight with temps in the mid 70s out
west to around 80 along the coast.

Long term (Monday night through Saturday)
Extended begins with a strong pressure gradient across south texas
as lee cyclogenesis across the central and southern plains
intensifies. Expect significant winds from Monday will carry over
into Monday night, especially over the waters where very hazardous
boating conditions continue through Monday night and into Tuesday.

As an upper disturbance crosses the region on Tuesday, all eyes will
be on temperatures aloft as rain chances will be predicated on cap
erosion. Models continue to suggest best chances to break the cap
will be over the victoria crossroads, with lesser chances west and
south of there. Present indications are for a dryline to push out of
west texas across the western brush country, with very warm
afternoon temperatures west of that dryline. Warm and dry weather
will continue on into memorial day weekend as an upper ridge slowly
noses its way toward us.

Models continue to indicate that minor coastal flooding will
continue through midweek.

Marine
A weak to moderate onshore flow will continue through tonight
along the middle texas coast. Onshore flow will strengthen late
tonight into Monday morning. The strengthening pressure gradient,
due to a potent shortwave moving from the four corners region into
the central and southern high plains, will produce widespread sca
conditions on Monday and Tuesday. A gale warning may be needed
Monday night as the strong gradient suggests at least frequent
gale force gusts. Seas are expected to reach at least 9 to 11 ft
Monday night and Tuesday. The gradient is expected to weaken late
Tuesday, but will restrengthen again on Wednesday and remain
moderate to strong into the weekend. As a result, small craft
advisories may be needed for much of the upcoming week

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.
