Discussion
The regional weather pattern has (and ultimately will) transition
to more summer-like this coming 7 day period. As already
eloquently stated by the previous shift's climate research, these
past few days of warmer than normal diurnal temperature (maximums)
will be a preview of the next several days. While afternoon
maximum temperatures have only been a few degrees warmer than mid
to late may MAX temperature standards, the recent record
tying breaking very warm minimum temperatures have been the better
storyline. While moisture levels of between 1.2 and 1.4 inches
have fallen within the climatology ho-hum 50-75 percentiles, it
has been the stout overnight near surface southerlies that have
kept many mixed and only falling into the near sunrise upper 70s.

While we will not be experiencing 15 to 25 mph (Monday night &
Tuesday morning-like) overnight winds, subsequent daily nocturnal
winds will remain in the 5 to 10 knot range and, with slightly
lower pwats through late week, minimum temperatures will fall back
into the closer-to-normal average lower to middle 70s. With no
frontal passages expected in the near future, the dominant wind
will remain onshore. Thus, isolated early day streamer near-coastal
(sea-to-land frictional) showers, along with mostly overcast
skies, can be expected the next couple of mornings as the near
surface layer saturates up under the mid level warm nose.

Upper ridging is forecast to expand in from the east tomorrow and
this will guarantee a very summer-like weekend... More full Sun with
days warming from the sunrise low to mid 70s into the mid day lower
90s. Suppression brought on from a near 595 dam ridge centered over
the southeastern u.S. Should be enough to keep the area bone dry
over the weekend and into early next week. Cut and paste days in the
medium and extended period as each day will come in within a degree
of the previous day. The next chance of rain comes late Tuesday
through Wednesday... Low chances from a (potential) plains upper
trough passage dragging a weak mid-low level boundary into north
central texas. 'if' upper ridging does decide to concede a bit, then
expect modest chances for mid week rain. Of course, the alternative
of an anchored ridge translates to continued dry... Unseasonably warm
days achieving the average lower 90s. Current (up to 6 foot depth)
soil moisture values around 50% saturation will likely be much drier
after a full week of no measurable rain. This will feedback into
increasingly warmer afternoons. Too early to carelessly throw out
the "d" word though... .31

Marine
Moderate to occasionally strong onshore winds and elevated seas will
persist for the next couple of days. Expect a combination of
advisory caution flags for the remainder of the work week. Speeds
and seas should generally diminish as we head into the weekend, and
trend into a more typical summer-like pattern with higher winds
offshore at night that relax during the day. Pressure gradient
tightens again early next week with a corresponding increase of
winds seas.

Coastal flood advisory will continue along the coast. Minor coastal
flooding remains a possibility around times of high tide. Went ahead
and included the bayside portions of harris and galveston counties
(where we saw some impacts yesterday around seabrook and lynchburg)
to capture their high tide today. Expect increased wave run up and a
high risk of rip currents along area beaches. I think the highest
observed levels were probably observed yesterday and anticipate
impacts to be slightly less each day as we head into thurs fri. The
hope is these advisories won't be needed after Fri morning. 47

Aviation
MVFR conditions should lift intoVFR territory during the mid late
morning hours. South-southeast winds will increase this morning and
become gusty into the late evening hours. MVFR ceilings should
redevelop by mid evening and persist overnight. 47

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.
