Aviation
The weather will remain dry this afternoon into tonight at most
of the TAF sites. The only exception is at kapf TAF site where
there could be a few showers or even a thunderstorm this
afternoon. However, the coverage will be few and far between to
put it in the kapf TAF site at this time. The ceiling and vis will
also remain inVFR conditions at all of the TAF sites through
tonight, but could fall down into MVFR or even ifr conditions with
the passage of the showers or thunderstorms at kapf TAF site this
afternoon.

Prev discussion issued 930 am edt Tue may 21 2019
update...

high pressure will continue over the southeastern united states
today into tonight. This will keep an east northeast wind flow in
place over south florida. Drier air is also working into the
region from the western atlantic waters this morning, as the pwat
values from mfl sounding is only around 1.12 inches which is
around the 10th percentile for this time of year. The 500 mb
temp is also only around -6.1c which is very warm for this time
of year. Therefore, most of south florida should be dry today into
tonight, except for the west coast metro areas where there could
be a low chance of showers and may be a thunderstorm this
afternoon especially where the sea breezes collide. Any storms
that do develop will more likely be the typical popcorn type
thunderstorms.

Rest of the forecast looks good at this time and no other changes
are planned.

the weather should remain dry today over the TAF sites with mainly
an easterly wind flow. The only exception is at kapf TAF site
where the winds will swing to a westerly direction after 17z due
to the west coast sea breeze. The ceiling and vis will also remain
inVFR conditions today.

discussion...

short term (today through Thursday)
synoptic pattern over the rest of this week will be fairly
stagnant, with high pressure being the dominant feature. There
will be one more afternoon with sufficient moisture and light
enough flow that today some showers and a few thunderstorms are
expected as gulf and atlantic breezes collide over southwest
florida. Thereafter, subsidence and drier air filtering in from
the northeast should suppress convective development through the
week. Surface ridge building in from the northeast will provide
for gradually increasing easterly flow, with fairly breezy
conditions expected by Thursday. This atlantic influence will curb
warming some, but still expect east coast urban areas in the mid
to upper 80s with low 90s elsewhere.

Long term (Thursday night through Monday)
expansive upper ridge will continue to build over the southeastern
conus, likely leading to a heat wave to points north of south
florida. For our region, easterly flow will keep temperatures from
reaching excessive levels, and the relative humidity will remain
fairly low as well through the weekend. Both temperatures and
moisture may increase next week, but until then, highs will mainly
be in upper 80s east coast, low to mid 90s west, with lows in the
70s, with rain-free conditions prevailing.

Marine...

pressure gradient will increase as high pressure builds in from
the north and east over the next few days. Atlantic waters may
need a small craft advisory Wednesday night through Friday, and
even seas will increase to 4 to 6 feet. Some thunderstorms are
possible on gulf waters this afternoon, otherwise dry conditions
are forecast.

Aviation...

vfr conditions expected to prevail during the next 24 hours at all
terminals. Light easterly winds will turn easterly 10-13kt after
15z, with the gulf coast sea breeze moving into apf around
17-18z. Showers and storms possible over the interior once again
this afternoon, remaining away from TAF sites.

Beach forecast...

low to moderate risk of rip currents will prevail today on
atlantic beaches, but increasing easterly flow will lead to
increasing risk Wednesday, with a high risk of rip currents likely
Thursday into the memorial day weekend.

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 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.
