Discussion
Today... A weak low level inverted trough over the northern bahamas
will move west northwest across south central portions of the local
area. Satellite precipitable water estimates are around 2 inches
with this feature, and that is about what the GFS shows values
rising to. Much drier air aloft will affect northern sections, so
a rather sharp pop gradient is expected. MOS shows values ranging
from 20% in the far north to 50% central south. This looks
reasonable and won't deviate much from guidance values.

Tonight... Low level flow is forecast to gradually veer to the
southeast south in the wake of the weak inverted trough. Rather
high moisture will linger, but nocturnal convection should confine
itself mostly to the atlantic after midnight. Have kept token small
pops mainly for the coast.

Wed thu...

deep moisture plume extending W SW out of a tropical disturbance off
the carolina coast will lift north of the i-4 corridor by daybreak
wed, then into the fl panhandle Wed night. Bermuda ridge axis will
rebuild over central fl in its wake, resulting in a S SE flow
pattern thru the h100-h70 lyr. Rap40 analysis shows decreasing
low mid lvl moisture over the central southern bahamas, what will
become the source region for central fl thru midweek: h100-h70 mean
rh values forecast blo 70pct before midday, and as low as 50pct over
the treasure coast lake-o region by late in the day. Mid lvls dry
out expected to dry out as well as upstream h85-h50 dewpoint
depressions increasing from 5-7c over the NRN bahamas to arnd 15c
over the SRN bahamas.

With h100-h70 flow bcmg S se, expect slow moving sea breeze
boundaries thru the day, resulting in diminished potential of
mesoscale boundary interaction. Add in the dry air advection, and
precip chances will be blo 50pct. Indeed, LCL wrf model remains
quite bearish on precip thru midweek, largely due to these issues.

Lingering moisture early Wed from the moisture band's passage thru
central fl will allow slightly higher precip chances... 30pct along
the coast lake-o region, 40pct interior counties from osceola
northward. Pwat values dropping to arnd 1.50" on thu, with
corresponding pops dropping to 20 30pct. No chance in airmass...

ergo, no sig chances in MAX min temps: aftn maxes in the u80s l90s
and mrng mins in the l m70s.

Fri-mon...

the bermuda ridge axis will drift north of the fl border by week's
end, where it will block out a weakening frontal boundary pushing
into the deep south. Deep easterly flow pattern will prevail thru
the h100-h70 lyr, bcmg E NE on Mon as the ridge axis retrogrades
into the deep south. Easterly flow regimes tends to keep precip
chances blo 50pct for east central fl, especially this late into the
wet season with a rapidly decreasing Sun angle. Rap40 analysis of
the tropical atlc east of the bahamas shows low mid lvl moisture on
the low side with h100-h70 mean rh values generally AOB 70pct and
h85-h50 dewpoint depressions arnd 15c. Precip chances AOB 30pct.

Minimal day to day changes in temps given the persistent easterly
flow, maxes in the u80s l90s, mins in the l m70s.

Aviation A few small showers have been moving into the coast
during the early morning hours, so local MVFR will be possible at
a few terminals. An area of higher moisture convergence is
forecast to spread from the northern bahamas across the south
terminals after sunrise and eventually spread up to about kmlb-
kism-kmco during the late morning and afternoon. Scattered
showers and isolated storms are expected but have gone with just
vicinity showers storms for now. The strongest activity should be
over the interior this afternoon and shift to the western
peninsula by early evening, but some showers or storms could
linger in the moist air mass across east central florida,
especially south of klee-ksfb-ktix.

Marine
Today-tonight... The pressure gradient is supporting a 10-15 knot
east flow early this morning but should ease slightly as a weak
inverted trough moves inland across southern sections this
afternoon. Winds will also become southeast behind this weak
trough. Seas will stay elevated 4-5 feet offshore due to a
persistent swell. Scattered showers and a few storms are expected
mainly south of CAPE canaveral today.

Wed-sat... Bermuda ridge axis will slowly drift from the central fl
peninsula into the deep south thru the end of the week. Position of
the ridge will generate a gentle to moderate S SE breeze thru
midweek, backing to the E SE by week's end. Sfc bndry lyr winds bcmg
due east in the aftn hrs each day with the formation of the east
coast sea breeze. Seas 3-4ft areawide thru midweek, rebuilding up to
5ft in the gulf stream by daybreak Fri as the ridge axis lifts into
north fl and allows an easterly swell component to works its way
into the LCL atlc. Shra tsra chances AOB 30pct.

Daytona beach tied their record warm low temperature of 78 degrees
