Short term
Stacked high slowly building in over the area through the
remainder of the week. Wind speeds will slow even further today
and will be just enough to flutter a few leaves by the weekend.

Today, winds speeds should remain high enough to keep the column
ventilated but as we move to the weekend, this will stop and with
little movement of the heat that builds in the boundary layer, it
will become stagnant and quite warm. This will be the first
moderate warm spell for this summer. At the moment, heat index
values look to only reach around 100 by Sunday. But since this is
the first warm stretch of the summer, people may not be ready or
used to it at first. But limiting outdoor activities or getting
those activities done during the morning would probably be most
comfortable. Staying hydrated is always a good idea as well.

Ridging will remain near the area for the start of next week but
may back off just enough to allow a slightly enhanced flow of
southeasterly winds possibly as early as Monday. This will once
again help to mix out the boundary layer keeping temps a few
degrees lower.

Now to discuss the models continued solution of a tropical system
in the southern gulf. There is a current sfc low invest by the
hurricane center over the eastpac located at about 11.0n 87.4w at
7pm central time yesterday. This low is expected to drift east or
northeast over the next several days possibly coming inland over
nicaragua and costa rica. This is the system that the current
global models are trying to regenerate once completing its journey
over central america and moving offshore over the western
caribbean. This is not unheard of and for the last several years
we have observed some type of tropical system either in late may
or early june within the atlantic basin usually in the caribbean
or gulf of mexico. Although a full strong hurricane like the gfs
is trying to show would be an exceedingly rare phenomenon. More
often, this time of year would support something more along the
lines of the euro which keeps the system rather disorganized and
either an open wave or weak closed low over the western caribbean,
yucatan, then extreme southern gulf. Keep in mind this is way out
in the forecast... Not this coming weekend but the next weekend.

No reasonable conclusions can be drawn for anything this far out
but model solutions and trends will continue to be watched but
there is no concern over this system at the moment.

Aviation
Some patchy clouds during the late overnight hours could produce
some brief MVFR ceilings. This has happened briefly in the last hour
or two at several locations. High end ifr isn't out of the question.

Any areas that do see flight restrictions early this morning will
see improvement toVFR by 15z. Look for a repeat of conditions
overnight tonight as the pattern is going to be changing very little
over the next couple of days. 35

Marine
Upper ridging over the southeastern us will keep a persistent
southeast to southerly onshore flow over marine areas through the
forecast period. Winds may briefly move into exercise caution ranges
above 15 knots during the diurnally favored evening hours on a
couple of occasions, primarily over the western open waters. Do not
anticipate any lengthy periods of headline worthy winds. 35
