Discussion
Memorial day weather will be pleasant with continued relatively
lower humidities making the partially cloudy day bearable as
afternoon middle 80s to lower 90s will not feel as muggy...

also assist in regulating interior heat indices to the average
middle 90s. As eastern texas remains on the western periphery of
southeastern u.S. Mid to upper level ridging, expect more of the
recently warm and dry weather similar to this past weekend's
conditions. Other than a brief sprinkle or short-lived shower,
subsidence provided by higher heights will again win out and keep
everyone dry. Southerly winds will remain the rule, becoming a bit
gusty later in the day and into the early evening hours. If
outside during the holiday in either work or play mode, proper
hydration and liberal use of the sunscreen should remain the core
staples to any outdoor activity. Beachgoers should should remain
cognizant of the rip current threat, albeit rips will be slightly
weaker. Always swim within sight of a lifeguard and away from
rocks, jetties and or piers.

The broad cyclonic circulation centered over central california
will evolve into a great basin trough through the day. This upper
low trough will lift northeast into the upper rockies and the
northern plains states by Wednesday morning. The positively-tilted
trough axis will stretch back to the southwest as a lobe of
southern energy pendulums forward into the desert southwest and
northeast into the ok-tx panhandles Wednesday. This region of
higher PVA riding up and over the east gulf upper ridge will be
entering a less stable, near 90 f heated and more humid (near 2
inch pwat) central and eastern texas environment; the ultimate
impetus to a possible qlcs passing across oklahoma and northern
texas during the day Wednesday. This mesoscale feature is forecast
to push out cool pool-induced outflow boundaries towards and into
eastern texas Thursday. Thus, a flip of a coin chance for showers
and thunderstorms Thursday targeting this day as our best chance
of breaking out of this recent dry spell. While, what our Thursday
air mass lacks in bulk shear will be made up for in the thermodynamics;
convective indices certainly support northern into central county
scattered daytime thunderstorms. High pressure builds in from
late Thursday on into the first weekend of june. Models are in
better agreement that, other than some light QPF shower action
(e.G., under the cap, sea breeze-induced), the late work week and
june's first weekend will be dry and mostly cloudy as texas falls
under a more zonal mid-upper flow pattern. Southern-based upper
ridging expands north into the state early next week and eventually
centers over the northern gulf. A similar 593-ish dam upper ridge
(to that of the ongoing southeastern states high) planted over us
will guarantee another extended period of dry weather. 31

Aviation
Vfr at the moment but still expect patchy MVFR ceilings to
develop and spread north beneath the expansive ci deck. Slightly
drier air flowing in across the region this morning but should be
changing this afternoon with ll dewpoints increasing.VFR mid
morning through the afternoon. Gradient tightening up tonight and
should see more sc develop and MVFR ceilings. Not high confidence
on timing but more likely be 08z could be sooner. Gusty and
stronger winds should be mainly over the cll area tonight but
Tuesday morning stronger winds on tap and longer period of MVFR
ceilings into the morning. 45

Marine
Southeasterly winds of around 15 knots offshore and 10-15 knots
nearshore bays this morning should be increasing going into the
evening hours and expect SCA conditions by mid evening as gradient
tightens and LLJ expands into setx utcw. Moderate onshore flow
Tuesday night as upper jet noses in across setx and LLJ redevelops
over the region. This period of stronger winds should taper off
Wednesday night Thursday morning as a weak cold front eventually
slides into setx late Thursday and early Friday. Winds becoming
more easterly as pressures fall over mexico Friday Saturday.

Tides lower than the last few days but still 1-1.4 feet above the
astronomical. Some runup still ongoing and expect more moderate to
occasionally strong rip currents to prevail today so will be keeping
the beach hazards statement going. Tonight with the increase in
winds and increasing period and height expect the rips to re-strengthen.

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.
