Synopsis for the middle texas coastal waters.. Deepening low pressure in the southern plains today will result in a strengthening of the onshore flow through tonight. A weak to moderate onshore flow is then expected Monday and Monday night. An area of low pressure will deepen over west texas in advance of an upper level storm system Tuesday. Onshore will increase Tuesday and become strong Tuesday night into Wednesday morning. A cold front will approach the region Wednesday providing chances for showers and Thunderstorms. Front should move through the waters Thursday with weak to moderate offshore flow in its wake.

429 am cdt Sun mar 26 2017

Short term (today through Monday)
Deepening low pressure in the southern plains will induce an
increasing s-sw flow across south tx today. This will allow
temperatures to heat up to as much as 10 degrees above normal once
morning fog and clouds mix out. Breezy to windy conditions are
also expected along the mid coast and southern bays where small
craft advisories are in effect for this aftn. Winds relax tonight
as frontal boundary stalls north of the area. Expect more fog
tonight due to the weaker gradient and moist boundary layer.

Monday looks more tranquil but still warm and humid as the next
storm system takes aim at the pacific southwest.

Long term (Monday night through Saturday)
The next storm system in the progressive upper level flow pattern
will be digging through the great basin Monday night with an upper
low south of the four corners region Tuesday. Onshore flow will
increase Tuesday as a low pressure area deepens over southwest texas
with windy to breezy conditions over the coastal plains Tuesday and
Tuesday night. Low level jet will increase to 50 knots Tuesday night
transporting moisture into the region. But the jet shifts to the
east early Wednesday as a pacific front/dryline moves into the brush
country as the upper low moves into the texas panhandle.

Looking at the ECMWF and canadian models, there is some concern the
dry air will advance into the region and limit convective potential.

Will still hold on to pops for Wednesday but lowered them slightly
keeping them below likely category for the victoria crossroads. The
frontal boundary may stall over the coastal areas Wednesday night
with adequate moisture remaining in this region. As the upper low
moves northeast into oklahoma/kansas Wednesday night, a secondary
short wave trough will round the base of the upper low into the hill
country. Will keep chance pops over the northeast part of the
forecast area for possible redevelopment of convection Wednesday
night and lingering along the coast Thursday ahead of the front.

Conditions dry out behind the front Thursday night as the
upper low moves through the ozarks into the mid mississippi river
valley Friday morning. The next upper level storm system will be
moving into the great basin Friday morning. Models are not in solid
agreement where this low will be Saturday. The GFS deterministic and
ensemble are south of the four corners region with the ecmwf
deterministic and ensemble more to the east-northeast in new mexico,
while the canadian digs the system more into northern mexico. Looks
like this upper level storm system will be stronger with a deeper
trough into northern mexico. Will show rain chances returning on
Saturday with pops in the chance category for the entire area.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
