Frost advisory until 8 am est this morning for
glades hendry counties...

Dry and cool weather will continue for most of
the week into this weekend...

Discussion
Temperatures early this morning fall fallen into the 40s over the
interior areas to around 50 over the metro areas, except west of
lake okeechobee where the temperatures were already down to around
40 degrees. Temperatures will continue to cool through the early
morning hours and be down into mid to upper 40s metro areas, lower
to mid 40s interior areas and mid 30s west of lake okeechobee by
sunrise. Areas of frost should develop over the areas west of
lake okeechobee in glades and hendry counties around sunrise
today due to the very cool temperatures. Therefore, the frost
advisory will continue for glades and hendry counties until 8 am
est this morning.

High pressure over the gulf of mexico will extend into the florida
peninsula today into tonight, before weakening a little bit on
Tuesday allowing for a dry cold front to move southward from the
north and through south florida Tuesday night. This will allow
for the wind flow to remain northerly today into tonight keeping
the cooler air in place, before backing to a westerly direction
on Tuesday and allowing for a little bit of warmer air to work
into south florida. The warmer air will not last long as the
cooler weather will return to south florida on Wednesday behind
the cold front.

Today's highs will only get up into the 60s over most of south
florida, except near 70 over the southeastern areas. Lows tonight
will again be in the 40s over most areas, except around 50
southeastern areas and around 40 degrees west of lake okeechobee.

Tuesday highs will be 70s over all of south florida with lows
Tuesday night in the 40s interior areas to 50s metro areas. Highs
on Wednesday will then only get up into the 60s again with lows in
the 40s for most areas.

Extended forecast
High pressure over the gulf of mexico will then build back into
the florida peninsula on Thursday, before weakening again on
Friday allowing for another cold front to move through south
florida. This front could produce a few showers along it as it
moves through the area on Friday. Therefore, a slight chance of
showers will remain in the forecast for Friday.

The high over the gulf of mexico will then move east across the
florida peninsula this weekend and into the western atlantic
waters early next week keeping the weather dry over south florida.

The wind flow over the area will also become more easterly this
weekend before swinging more to a southerly direction early next
week allowing for warmer air to work into south florida. Highs
will warm up to around 80 by end of the weekend with lows warming
up into the 60s, except around 70 southeastern areas.

Marine
The winds today will be northerly at 10 to 15 knots before backing
to a westerly direction on Tuesday. The winds will then swing to a
northerly direction by Wednesday with speeds increasing breezy
conditions. This will allow for the seas to remain below 6 feet
today into Tuesday, before increasing to around 6 feet in the gulf
stream and the offshore gulf waters by Wednesday. Therefore, the
scec will be drop the atlantic waters for today.

Beach forecast
With the decrease in the northerly winds over the gulf waters
today, the threat of rip currents have been lowered to moderate
conditions along the beaches of collier county. The atlantic
beaches of south florida will also remain in the moderate risk of
rip currents today due to the northerly winds of 10 to 15 mph.

Fire weather
The relative humidity will fall down into the 20s over south
florida today due to the very dry air in place. However, the erc's
will remain in the 20s along with the 20 foot winds remaining
below 15 mph. Therefore, no red flag warnings are needed for south
florida today. The dispersion index values today will also be less
than 20 around the lake okeechobee region with 20s to lower 30s
over rest of south florida.

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.
