Some cloud cover lingers across the southeastern part of south
florida early this evening, but skies should be mostly clear
across the area by midnight. For this update, I slowed the rate of
cooling during the evening hours based on recent temperature
trends and the latest guidance. However, no changes have been made
to tonight's low temperatures or wind chills.

Freeze warnings are in effect for glades and hendry counties. Wind
chill advisories are posted for glades, hendry, collier, inland
and metro palm beach, and inland broward.

aviation... Front in central fl expected to arrive 02z-04z
accompanied by gusty NW winds 10-13kts. Some MVFR CIGS currently
along front, not sure if they will arrive in south florida but
best bet is at kapf where have included tempo MVFR CIGS 02z-04z.

Otherwise, any clouds remainVFR becoming few into thurs. Winds
briefly diminish behind initial frontal passage late tonight,
picking up out of the nnw 12-15kts gust 20kts 14z-16z. Potential
for sites to veer nne later in the day, but have kept most more n
to nnw for now.

Freeze warning for glades and hendry counties
Wind chill advisory for portions of south florida

short term (tonight): cold front progressing quickly southward
through the florida peninsula this afternoon. Some high cirrus
clouds have been streaming across south florida this afternoon.

Expect these clouds to diminish overnight. Skies will be mostly
clear to partly cloudy during the evening, with additional
clearing overnight as drier mid-level air moves in behind the
front. Winds tonight will remain up near 10 mph from the nnw,
advecting in cold air from the north. The low temperature forecast
for tonight was lowered by an additional degree from our previous
forecast, based on the latest guidance. A freeze warning is in
effect for glades and hendry counties. Minimum wind chills will
range from the mid 20s in glades county to near 40 along the
southeast beaches. A wind chill advisory remains in effect for
glades, hendry, collier, metro and inland palm beach and inland

Medium and long range (Thursday through early next week):
surface high pressure will build in Thursday into Friday. This
will veer low levels winds back to the north northeast across
south florida. Once again, the atmosphere will be too dry to
produce any precipitation, with partly cloudy skies prevailing.

South florida is likely to remain dry through Friday night. Maximum
temperatures on Thursday near 60 for the northern interior to low
to mid 60s along the east coast metro, values 10 to 15 degrees
below seasonal norms. Maximums will slowly begin to rebound on
Friday as flow shifts more easterly. Over this weekend, a weak
shortwave drifting eastward across the gulf should allow for
deeper moisture to move northward over south florida. This
increase in moisture and weak instability may bring a better
chance for showers for the weekend, though confidence of
occurrence is still low to moderate. The shortwave moves away
early next week. However, there continues to be signs that a weak
frontal system may approach the area from the northwest as another
upper-level trough digs southward across the country's mid-
section. This feature could increase moisture again towards the
middle of the week.

Marine... A cold front will move through south florida waters late
this afternoon and early evening. Behind the front, strong
northerly winds of 20-25 knots are expected this evening through
tonight. Small craft advisories are in effect for both the gulf
and atlantic waters for breezy northerly winds and hazardous seas.

Conditions will show signs of improvement by late Thursday.

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 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 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.
