750 pm edt Mon oct 23 2017

Aviation
Brief MVFR ifr conditions will continue to impact the
northern terminal sites through early Tuesday morning, and
through early afternoon across the southern terminals as
shra and a few tsra continue to impact the region ahead of a
cold front. Outside of the convectionVFR will prevail.

South to southwest winds in the 7 to 10 knot range tonight
will gradually shift to the northwest and north after 10z
from ksrq north to ktpa, kpie, and klal, and after 14z
across the southwest terminals as the cold front moves south
through the region.

short term (tonight - Tuesday)...

the shortwave over the southeast has continued to lift
northeast so far today, taking the greatest height falls
and lift north of our forecast area. At the surface, the
cold front is continuing its slow trek southward, while high
pressure just offshore of new england continues to extend
southward toward the state. Radar imagery through the early
afternoon hours has shown much of the heavier shower
activity remaining over the gulf, with just a few areas of
light rain surviving over land until the past hour or so,
when a few heavier showers held on around the tampa bay
region.

The forecast for the rest of the day remains a tough one
regarding precip timing and coverage. Most model guidance
continues to show rather high rain chances given what is out
there now. The hrrr, in particular, is showing a more
organized line that moves into the nature coast this evening
and then becomes more diffuse as it sinks southward.

Although the main upper energy is lifting away, there is
still abundant moisture in place and we have gotten some
heating, so will leave at least a chance for rain in the
forecast for all areas through the first part of tonight
before gradually trimming pops back as we head toward
daybreak and the first front keeps slipping south.

Winds will have turned northwest except for about the
southern third of the forecast area by around daybreak
Tuesday. Another strong shortwave will drop southward
through the day, pushing the front even farther. Counties
from roughly highlands southwestward into hardee desoto and
charlotte lee will likely remain on the cloudy side with
some periodic showers while the rest of the area dries up
and mostly sunny skies return. Temperatures will range from
the upper 70s lower 80s to mid 80s as we start to transition
to a cooler day on Wednesday.

Long term (Tuesday night - Monday)...

cold front will be exiting the southern zones Tuesday
evening with a secondary boundary associated with the main
trough moving quickly south during the night bringing
increasing northerly flow and the real shot of cooler drier
air. A few lingering showers will be possible during Tuesday
evening south and east of a line from about winter haven to
venice then skies will gradually clear. However, late
Tuesday night into Wednesday morning some stratocumulus is
expected to develop over the eastern gulf associated with
the strong cold air advection and this could affect coastal
areas. Otherwise, surface high pressure will move across the
gulf and southeast states Wednesday and Thursday with
mainly clear skies and cooler drier conditions. During
Friday and Saturday the high will shift out into the
atlantic ocean with a more east to northeast flow bringing
moderating temperatures and moisture. Global models are
still depicting slightly different scenarios late in the
week through the weekend, but the overall trend has
continued to bring some deeper moisture back into the region
along with the chance of a few showers ahead of the next
mid upper level trough and associated surface cold front.

This front is expected to move across the region Sunday
followed by another shot of cool dry air for early next
week.

Marine...

an approaching cold front will bring periods of showers and
a few thunderstorms today. Winds will shift to the
northwest tonight through Tuesday as the front slowly drops
southward and then will increase Tuesday night into
Wednesday, with advisories likely needed. Winds will then
slowly relax through the end of the week.

Fire weather...

a cold front will slowly move southward through the area
tonight into Tuesday, with a chance for showers and a few
thunderstorms in the forecast. A secondary cold front will
move through the area Tuesday night, with much cooler and
drier air then filtering into the region for Wednesday and
Thursday. A few areas generally north of the i-4 corridor
could see relative humidity values of 35% or even slightly
lower for Wednesday afternoon and then those values are
forecast to expand southward for Thursday afternoon. Low-
level moisture returns for Friday into the weekend. No
significant fog is expected for the next few days.

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.
