Synopsis..Stronger winds and higher seas are expected the rest of the week with a tightening pressure gradient between building surface high pressure over the southeast u.s. And a developing low pressure system in the central plains. Small craft advisories may be needed at times for the lower texas coastal waters. Light to moderate southeast winds and low to moderate seas are expected this weekend as the gradient relaxes, but small craft exercise caution conditions will be possible.

area forecast discussion
national weather service brownsville tx
330 pm cdt Wed jun 28 2017
.Short term (now through Thursday night): a seabreeze early this
afternoon initiated another round of showers and thunderstorms
across the coastal counties with locally heavy rainfall of 1 to 2
inches across portions of the lower rio grande valley. The boundary
will continue to spark additional convection through this afternoon
as it progresses westward. After sunset, rain chances should
diminish with the exception of a few streamer showers over the gulf
waters overnight and near the coast. Weak mid-level trough axis will
continue to linger along the lower tx coast through much of the
forecast period and moisture should be deep enough to keep slight to
chance pops in the forecast for the eastern half of the area. The
pressure gradient will tighten late tonight as surface high pressure
builds over the southeast u.S. And low pressure deepens over the
central plains. Winds will increase out of the southeast with
daytime heating, which may gust up to 25 mph at times Thursday
afternoon. Temperatures will be a few degrees above normal with
highs ranging from the upper 90s to 103 near falcon dam.

.Long term (Friday through Wednesday): the combination of ample
moisture (especially along the coast), daytime heating and a
weakness in the 500mb ridge will provide a slight chance of isolated
showers and thunderstorms on Friday. The 500mb ridge over the
eastern gulf of mexico is expected to build westward over the region
on Saturday while the 500mb ridge over the southwest united states
and northern mexico provides subsidence across the area through
the weekend. Limited low to mid level moisture will support
generally rain-free conditions Saturday through the middle of next
week. Above normal temperatures temperatures will prevail through
the forecast period with mid level ridging overhead.

.Marine (now through Thursday night): light and variable winds
over the marine areas this afternoon will increase out of the
southeast as high pressure shifts off the southeast u.S. Coast.

Thursday, winds will increase and seas will build to 3 to 5 feet.

Small craft advisories are possible Thursday and Thursday night.

Friday through Monday... Surface low pressure across west texas
interacting with high pressure across the gulf of mexico will
support moderate to strong southeast winds Friday through
Saturday. Moderate southeast winds will prevail by Sunday as the
pressure gradient weakens. Exercise caution conditions likely with
small craft advisories possible for portions of the lower texas
coastal waters Friday through Saturday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
