Short term
Boundary layer depth is sufficient enough at around 2kft thick to
allow convergent winds to lift abundant sfc moisture enough to get
a few isolated sprinkles this morning. These cloud tops hit the
inversion at 2kft and put the breaks on. By 15z this morning, the
inversion lifts to 2.5kft but as the temp warms at the sfc it
will cause the rh values to lower which will cause cloud bases to
rise. This rise in cloud bases will begin to cause the total
cloud depth to become more shallow not allowing enough depth for
these sprinkles to occur any longer. All light rain which is
isolated at best will dissapear by mid morning. This isolated
light rain pattern with a deep morning boundary layer is not that
unusual within moisture loading areas ahead of fronts during the
early summer. The interesting thing here is the sun's heating
itself is what causes this light rain dissipation when any other
time, heating is needed to produce deep convection. But convective
currents will be ongoing, we just won't have much visual evidence
of it since there will be very dry layers above the boundary
layer this afternoon. All this was said to simply give the reason
for the token tens shown in the precip fields for this morning.

Seems better than a redundant stacked high speech.

At some point, the dry hot weather will break for at least a short
time. This normally comes in the form of a weakening stalling
front that is just able to make it close enough to promote clouds
and showers that help keep temps cooler. Or from easterly waves
that begin to traverse the gulf at a more northern latitude as the
summer begins.

Aviation A scattered to broken deck of stratus ranging from 1500
to 2500 feet will affect all of the terminals through around 13-14z
this morning. Daytime heating and increased boundary layer mixing
will clear out the lower stratus deck after 14z, and expect to see
prevailingVFR conditions take hold at all of the terminals through
the evening hours. Another round of low stratus ranging around 2000
feet is expected to redevelop after 06z tomorrow. 32

Marine Persistent southeast flow of 10 to 15 knots is expected
across the coastal waters through Saturday as a surface high remains
parked across the eastern gulf. There may be brief periods when
winds increase to 15 to 20 knots over the far western waters today
and tomorrow with peak winds generally expected during the overnight
hours when thermal mixing over the warmer waters increases. High
pressure will become more centered over the region on Sunday
resulting in much lighter and more variable winds. The high is
expected to shift back to the east by Monday, and a return to
onshore flow of 10 to 15 knots is expected. Seas of 1 to 3 feet are
expected in the sounds and tidal lakes through the period. Over the
open gulf waters seas of 3 to 5 feet should prevail. 32

Decision support
Dss code: blue.

Deployed: none.

Activation: none.

Activities: several river flood warnings.

Decision support services (dss) code legend
green = no weather impacts that require action.

Blue = long-fused watch, warning, or advisory in effect or
high visibility event; marginal risk severe or
excessive rain.

Yellow = heightened impacts with short-fused watch, warning or
advisory issuances; radar support for slight risk
severe or excessive rain.

Orange = high impacts; enhanced risk severe; nearby tropical
events; hazmat or other large episodes.

Red = full engagement for moderate to high risk of severe
and or excessive rainfall, or direct tropical threats;
events of national significance.

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 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.
