Discussion
Slight risk for severe storms this afternoon and evening...

today-tonight... Not much change from recent line of thought.

Central fl is in for active wx thru daybreak Thu as a vigorous and
hi amp short wave over the nation's midsection is fed by a
meridional 110kt h30-h20 jet MAX digging over the central plains,
and a 115kt zonal jet over the lwr ms valley. Just ahead of the trof
axis, a large, albeit amorphous sfc low blanketing much of the tn oh
river valleys will dvlp into a well organized storm system as it
lifts into the great lakes region thru tonight.

A preexisting stationary front over the NW gomex extending NE into
the carolinas has left the h100-h70 pressure field over the deep
south W atlc rather low, eroding the WRN flank of the atlc ridge
axis back to the bahama bank. This will allow the dvlpg storm system
to crank its own frontal boundary over the lwr ms valley thru the
deep south today, then into central fl by daybreak thu. The
stationary front has also pre-moistened the airmass over the
gomex... Latest rap40 analysis showing h100-h70 mean rh values
largely AOA 70pct.

Deep and strong S SW flow ahead of the front will tap tropical
moisture over cuba and the NW carib. This will combine with moisture
pooling within the approaching frontal trof to push pwat values into
the 1.75"-2.00" range by late this aftn. Precip likely to
categorical as the airmass becomes nearly saturated. Mid lvl
vorticity is somewhat lacking, but dynamic support will be provided
by strong h85-h30 omega lift and moderate h30-h20 divergence.

Considerable mid upr lvl cloud cover will hamper sfc heating a bit,
but Sat photos show these thinning a bit over the ERN gomex. Areas
that break out from this cloud cover will warm rapidly under the
s SW flow... LCL wind profilers are measuring a solid 20-25kts of sw
flow thru 10kft over central south fl... Increasing to arnd 35kts
over north fl. H100-h70 mean winds expected to freshen to 30-35kts
by midday, 35-40kts by sunset, contg overnight, raising the
potential for strong to severe wind gusts with any deep convection
that may dvlp. Cannot rule out hail, though with h50 temps btwn
-8 -9c and h70-h70 lapse rates btwn 6.0-6.5c km, this threat will be
limited.

One interesting note... GFS does indicate modest helicity lvls thru
the 0-3km lyr by sunset tonight over the NRN cwa, pushing into the
srn CWA in the predawn hrs. While the threat is quite low, rotating
storms cannot be completely ruled out.

Mid upr lvl clouds may hamper initial heating, but expect the S sw
flow will compensate for much of that. MAX temps in the m u80s along
and north of the i-4 corridor... U80s l90s to the south. Steady wrly
flow and high cloud cover will keep min temps in the u60s north of i-
4, and in the l m along the space and treasure coasts lake-o area.

Thu... Mid level trough extending from the ohio valley to the florida
panhandle Thu morning will move eastward quickly into the afternoon
with the trough axis swinging offshore by late afternoon. At the
surface a trailing front will bisect the northern peninsula in the
morning and move southeast and offshore into late afternoon.

Convection should be ongoing Thu morning across central and southern
sections and then transitioning toward okeechobee county and the
treasure coast into mid to late afternoon. A strong upper level jet
streak will round the base of the trough into the afternoon hours
across north fl with the strongest low level winds in the morning
hours between h9-h8 to 35-45 knots across SRN areas. SPC does not
outlook severe storms for Thu but could be some strong storms mainly
across the SRN half of the area from the morning hours into mid
afternoon. Pops will range from 20-30 across NRN areas to likely (60-
70) across okeechobee county and the treasure coast. Highs should
reach the mid to upper 80s with breezy to windy offshore flow.

Thu night... Deep layer drying is forecast as high pressure builds
over the peninsula behind the front. Skies will be mostly clear with
lows in the 60s.

Fri-sat... High pressure across the east central fl on Friday will
shift slowly eastward into the atlc by Saturday. A very dry airmass
in the h8-h3 layer will keep forecast mostly sunny and dry. Highs in
the upper 80s to around 90 will warm a few degrees across the
interior on Saturday into the lower to mid 90s with a weak wind flow
regime and a slow moving east coast sea breeze.

Sun-wed... Mid level ridge across central fl will elongate eastward
into the atlc by early next week. Light southerly flow around the
atlantic ridge and a gradual increase in low level moisture should
allow for slowly increasing pops by Tue wed. Will continue very low
rain chances Sunday with possibly enough moisture around lake
okeechobee for some inland sea breeze showers or storm in the
afternoon. For Monday, will cap rain chance at 20 percent with a low
chance for a shower storm along the inland east and west coast sea
breezes. Shower thunderstorm chances will increase slightly to 30-40
percent range into mid week with sea breeze interaction across the
interior expected by late afternoon early evening each day. Morning
lows in the lower to mid 70s with highs upper 80s to around 90 coast
to the lower to mid 90s over the interior.

Marine
Today-tonight... Hazardous boating conds as a brisk SW breeze dvlps
ahead of an approaching frontal boundary... Moderate to fresh
nearshore and fresh to strong offshore. The offshore wind component
will limit sea heights 3-4ft nearshore and 4-6ft offshore thru this
evng but also will generate rough, short pd wind waves AOB 6sec.

Offshore seas building up to 7ft aft sunset. Nmrs shras and sct
tsras moving offshore, some with sfc wind g35kts. SCA for winds all
areas thru 02z this evng, transitioning to a full SCA for the
offshore leg aft 02z.

Thu... Sw winds to 20-25 knots and gusty will become west in the
afternoon with showers storms mainly south of the CAPE from the
morning into the afternoon hours. Small craft advisories will
continue into the afternoon with winds seas hazardous offshore for
small craft.

Fri-sun... Lighter winds developing Friday and into the weekend will
allow seas to subside to 2-3 ft. The east coast sea breeze
circulation will develop each afternoon turning winds onshore near
the coast during the late afternoon and evening hours each day.

Fire weather
Thu... Strong SW W low level flow will raise dispersion levels to the
very good category. The chance for lightning storms will be mainly
from osceola brevard counties southward with activity pushing
southeast away from the area into the late afternoon early evening.

Min rhs will drop to 40-45 percent across the NRN interior in the
late afternoon.

Climate
Melbourne tied a record high of 95f on Tuesday and vero beach broke
a record high of 95f. Melbourne also tied its record warm low for
yesterday of 76f last set in 2007.
