What's New / NOTES
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Update
Minor changes to the forecast this evening, which consisted of
mainly adjusting temperatures and dewpoints to reflect most recent
observations. Clear skies tonight will help to bring our low
temperatures down into the lower 70s along the coast, to low-mid
60s farther inland. Sunny skies will prevail for your Thursday,
with model guidance and forecast sounding analysis bringing high
temperatures back into the upper 80s and lower 90s across SE tx.

Moisture tomorrow will also begin to build back in, with
dewpoints in the mid-upper 60s by late afternoon, but do not
expect pops to return to the forecast until late this weekend.

vfr conditions expected through Thursday afternoon. Winds may stay
up a bit, but expect light winds by around 02-03z time frame.

Winds should pick back up mid to late morning Thursday with breezy
conditions Thursday afternoon.

discussion...

water vapor imagery nicely depicting the surge of drier air rushing
into the state in response to ridging filling the void of the
northeastern-exiting upper low moving up into the ohio river
valley. At the surface... High pressure centered over the lower rio
grande is creating a brisk northwest wind with overall subsidence
keeping skies mostly sunny and warming this afternoon's temperatures
into the lower 80s. This resident post-frontal drier air mass will
begin to moisten up by sunrise tomorrow as offshore flow transitions
to onshore. A near-zonal upper air pattern will maintain westerly
mid-level steering winds leading to a continued relatively dry
atmospheric column through early Friday... Then steering flow will
turn around to the south-southeast around a northern gulf mid-level
high. Status quo weather through the end of the week... No precipitation
forecast and the diurnal temperature curve will best-fit the climate
trace.

The gradual breakdown of upper ridging centered over the western
gulf through the weekend will equate to a partially cloudy Saturday
becoming mostly overcast by Sunday afternoon. After a couple of
late week warm and muggy days in the upper 80s to lower 90s mid
to upper 70 mornings upper troughing moving across the central
plains Sunday into memorial day will open the way for a series of
passing shortwave disturbances. A weak and (becoming diffuse)
surface boundary will sag into the area over the holiday and this
may provide the needed lower to mid level focus for periods of
inclement weather. Depending upon the passage of the aforementioned
shortwave disturbances troughs... A scenario similar to the one we
just experienced yesterday could unfold on (or around) memorial
day. Model soundings look ripe for thunderstorm development to
quickly evolve into strong or severe early next week. While the
shear improves through Wednesday... Memorial day's thermodynamics
are impressive (1.5k to 2.5k j kg cape... 6-8 deg c km 0-3 km
lapse rates leading to high lifted indices) with higher k indices
support more areal storm coverage. Overcast and a more active
convective pattern Monday through Wednesday will regulate
temperatures to slightly below normal values. 31

light north winds will become light southerly by sunrise. Onshore
winds will quickly strengthen during the day as the pressure gradient
tightens in response to developing low pressure in the lee of the
rockies. A moderate onshore flow will prevail through the weekend
with low pressure over west texas and high pressure over the
eastern gulf of mexico. A scec may be required at times through
the weekend. A weak cold front will approach SE tx Sunday night
and the gradient over the water will relax and winds will begin to
decrease on Monday. A lighter onshore flow is expected for the
first half of next week. 43

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.
