Discussion
Showers and a few thunderstorms will continue across the coastal
areas and gulf waters throughout this morning before spreading
inland this afternoon. Lower pws (1.6-1.7) over the NE zones may
be a limiting factor for shower tstorm development across that
area. Inland convection should diminish heading into this
evening tonight, with the focus shifting to offshore once again
overnight tonight. The upper-level weakness currently over texas
will gradually shift towards the N gulf throughout the week this
week, allowing a similar diurnal pattern of showers and storms
over the waters overnight and inland during the day to persist
through Friday. By that time, the upper-level weakness will have
pushed off further into the gulf with upper ridging settling in
over texas in it's wake. This ridging will pretty much put an end
to rain chances this weekend and into early next week with hotter
and drier conditions settling over the region.

High temperatures and therefore heat index values will be on the
rise this week, reaching the low mid 90s (h.I. 98-105) by this
weekend and lingering through early next week. Although that seems
pretty warm, it's actually only a smidge above normal for this
time of year. 11

Marine
Ese flow this morning looks to continue though may back slightly
going into the late morning hours. Upper troughing with mid level
circulation centered near san antonio should drift west with low
level troughing to continue over the upper texas coastal waters and
coastal areas. Combination of the persistent upper support today and
low level convergence should maintain the presence of showers and
thunderstorms over the coastal waters. High pw air and the above
will also increase the heavy rainfall potential which could lower
visibility over the coastal waters at times to 1 mile or less. Can't
rule out a waterspout either this morning but not a very favorable
profile. Expect a slight lull to develop late afternoon over the
waters but then redevelop again tonight. Winds of 8-14 knots should
be dominate through Wednesday evening then increase to around 15 and
into the 15-20 knot range may need scec flags Thursday early .

Morning and again Thursday night.

Aviation
Showers and a few thunderstorms near gls-lbx-psx early this morning
withVFR conditions elsewhere. Expect some patchy MVFR CIGS vsby
around cxo and possibly even iah for a few hours between 09-13z
before CU begins to develop. Daytime heating and the very moist
airmass will likely lead to a proliferation of shra tsra across the
southern portions of setx and will probably be adding tempos to
iah hou sgr lbx for shra tsra between 16-23z... And vcsh into the mid
evening hours though may go longer again tonight as it did earlier
this morning.

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.
