Synopsis for high island to matagorda ship channel out 60 nm.. Weaker winds through the day as high pressure building in from the north will temporarily relax the onshore pressure gradient. As low pressure redevelops and deepens over western texas, the gradient will significantly tighten once again tomorrow into Tuesday. Onshore winds will strengthen to advisory levels by Monday evening.

area forecast discussion
national weather service houston galveston tx
419 am cdt Sun may 19 2019

Discussion
Early morning skies are mostly cloudy to cloudy across much of southeast
texas with temperatures in the upper 70s to around 80. Record high minimum
temperatures were tied yesterday at both cll and hou, and we might get
close to records again today at some of our sites (see climate section
below for more details). The MCS and associated showers and thunderstorms
off to our east and northeast continues to make progress further off
to the east, and all heavy rain is now out of our area. We will have to
keep an eye on any leftover boundaries for possible development in our
area today, but current thinking is that most of us will stay warm and dry.

Strengthening onshore winds resume tonight and Monday as the next southern
plains storms system organizes deepens. Our next best rain chances come
on Tuesday when this system sends its front this way, and we'll continue
to carry higher chances north and lower chances south. There might be a
chance for some strong severe thunderstorms with this system (see spc's
day 3 convective outlook), but best dynamics currently look like they
will be setting up well north of our area. The rest of the week is looking
warm and breezy with rain chances too low to mention in the forecast as
mid upper level ridging builds into the area from the east. If the models
are right, by the end of the week and on into next weekend upper level
ridging as well as surface high pressure will edge closer to us. Look for
a little less wind, slightly cooler overnight lows, slightly warmer
daytime highs and close to zero rain chances. 42

Marine
Southern plains surface high pressure expanding south into northern
texas will relax the recently tight onshore pressure gradient. Thus,
today's winds will be weaker over slightly lower seas. Lowering
northern mexico and trans pecos region pressure through Monday will
again tighten the onshore gradient enough to produce moderate to
strong southerlies through a good majority of the week. Seas will
build to their peak Tuesday morning... Average 6 to 8 feet nearshore
to near 10 or 11 feet offshore sea heights with longer periods of 8
or 9 seconds.

Coastal water levels will remain high and, with an early week return
to a strengthened long duration onshore fetch, coastal flooding will
become a concern. 3.5 to 4.0 feet above mllw will occur during
Monday through Thursday's high tides. These levels will cause water
to reach into the dunes and come across low lying sections of the
blue water highway in brazoria county and highway 87 along the
bolivar, especially east of caplen and rollover pass. Swimming
conditions will remain more dangerous as rip currents stay strong
this coming week. 31

Climate
Record high minimum temperatures were tied yesterday at both college
station (76 degrees last set in 2017) and houston hobby (77 degrees
last set in 2017).

For today, the record high minimum temperatures are 78 degrees set in
2017 at iah and hou, 80 degrees set in 2017 at gls (it has already
fallen to 79 degrees) and 77 degrees set in 1960 at cll.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
