High pressure continues to keep the weather dry today and tonight.
However, as a cold front approaches, the high is being pushed
eastward, and the pressure gradient across the region is
increasing. This has brought southeast wind to south florida,
with speeds around 10 to 15 kts, especially along the coastal
areas. Gusts of 20 to 25 kts have also been seen.
The front is forecast to approach the area tomorrow, bringing a
chance of showers and maybe a few thunderstorms. The GFS has
moistened up some, compared to previous runs. However, it still
looks as though most of any active weather will tend to be in the
lake region. The capes for tomorrow are not impressive, with the
gfs boundary layer CAPE less than 500 joules. There will be some
weak 500mb vorticity advection, but it will be stronger in central
florida, and weaken as it progresses southeast. Still, a front
moving into the area will bring instability, so have kept a slight
chance of thunderstorms in the forecast for much of south
florida, mainly towards the lake and possibly along both
The convective activity quickly exits on Friday, with the models
indicating dry weather returning after 00z Saturday. High pressure
builds in for the weekend, with the center well to the north, over
the mid-atlantic states. This will bring an southeast flow back
to south florida for Sunday, which may also bring allow for some
isolated showers in the lake region on Sunday.
The high quickly moves eastward, off the east coast by Monday
afternoon, ahead of another low pressure system. This next low
looks to be more vigorous than Fridays system for south florida.
Models have the front moving into the area Monday night or Tuesday
morning, with showers and possibly a few more thunderstorms for
south florida. The front quickly moves through the area, and is
to the south of the CWA by Wednesday morning. While this is a cold
front, the models do not have it bringing any cooler air to south
High pressure does not look to be able to build in behind this
front as both the GFS and the ECMWF are showing a large trough
digging into the eastern us, which will quickly bring another|
frontal boundary into the area for the end of the week.
High pressure will continue to weaken ahead of an approaching
cold front, that will move into the area tomorrow. This has
brought the wind increase from the southeast today. The wind will
continue to be be breezy and gusty through tomorrow. Also, along
with the front, will be a chance of showers, and possibly a few
thunderstorms, mainly in the afternoon over the atlantic waters.
Although, they cant be ruled out for the gulf waters either.
Conditions should begin to improve Friday night for a couple of
days. Then, another front is forecast to move into the region for
the beginning of next week, which could bring deteriorating marine
Along the atlantic coast, the wind has brought a moderate risk of
rip currents to all of the beaches along the south florida coast
today. The wind will become more southerly tomorrow, but will
increase, which could still potentially bring a risk of rip
currents to the atlantic beaches through Friday as well.
High pressure is moving to the east and the pressure gradient is
increasing across south florida. This has caused the wind to be
southeasterly, and increase with gusts to around 25 kts in some
locations. However, conditions are forecast to continue to beVFR
through the TAF period.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. 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 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.
