Discussion
Tonight and Tuesday...

the upper flow pattern will amplify in response to a series of
shortwave impulses dropping through the southeast conus. The leading
wave will shift an accompanying cold front through florida on
Tuesday. Low-level moisture and some limited instability will be
confined to the east coast and atlantic waters, where a chance for
showers will prevail for the day. Thereafter, a dry pocket will
arrive likely confining and showers to the atlantic waters and palm
beach county coastline through the evening hours. Temperatures will
remain seasonal with lows tonight ranging from the upper 50s for the
western interior to the lower 70s along the atlantic coast.

Wednesday through Friday...

a potent upper perturbation vort MAX will swing through the region
causing an overall amplification to the upper trough. With strong
divergence and mass evacuation aloft surface low pressure will
develop along the florida east coast, with the low tracking into the
western atlantic late in the period. A robust pressure gradient will
develop during this time as high pressure builds in behind the
departing low pressure trough. This will bring a prolonged period of
gusty n-ne winds to the area, especially over the atlantic waters.

1000-850 mb layer averaged wind speeds continue to suggest gust
potential into the 30-35 kt range over the atlantic waters and east
coast from Wednesday evening through Friday morning, and this is
consistent with a consensus of model guidance pinging gusts in this
same range (especially over the atlantic waters gulf stream). High
seas will build as a result, leading to hazardous marine conditions
which are likely to continue through at least the end of this
period. East coast and atlantic showers are likely during this
period, but QPF doesn't look overly impressive during this time.

Temperatures during this time shouldn't stray overly far from
seasonal norms, although they should be a bit cooler than average
given increased cloud cover and shower chances.

Saturday through Monday...

expect decreasing winds and quieter weather for the weekend with the
winds turning more easterly and moderating temperatures. Rain
chances may return by Monday as a front approaches from the
northwest.

Marine
Hazardous conditions return for Wednesday into Friday. Strong gusty
winds arrive on Wednesday into Thursday along with a n-ne long
period swell. Expect building seas of 9-14 ft in the atlantic
(highest in the gulf stream) and 4-6 ft in the gulf during this
time. Additionally, gale force gusts are possible, especially for
the outer waters. A small craft advisory is in effect for all
atlantic waters beginning on Wednesday, with a gale watch for the
outer waters offshore from palm beach county. Hazardous waves are
likely to continue for the atlantic late into Friday, and mariners
should exercise extreme caution.

Aviation
A few showers are drifting east into kopf where shra has been
added until 20z. Otherwise, pops are generally around 20 percent
through the TAF period, so maintained dry forecast. SE wind around
10 kt for eastern terminals today, calming tonight, then likely
becoming light and north northwest Tuesday morning, before east
coast sea breeze kicks in during the afternoon. Timing of this sea
breeze is uncertain at this time so for now have left the shift
out of the tafs.

Beach forecast
An elevated risk of rip currents will remain along the atlantic
beaches through a good portion of the week. For this evening, palm
beach county still has a high risk of rip currents while the miami-
dade and broward beaches will be at least moderate risk.

A cold front will bring deteriorating conditions on Wednesday
into Friday with increasing winds and seas. Potential hazards
include rip currents, high surf, beach erosion, and coastal flood
impacts. A high surf advisory or coastal flood statement may be
required for some portion of this period, so keep up with this
evolving forecast.

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.
