Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
739 AM EDT Mon Jul 31 2017
.AVIATION...

knots or higher will be possible at times. Brief periods of VFR will
be possible in some breaks, but VFR becomes more likely later today.

.Prev Discussion... /issued 540 AM EDT Mon Jul 31 2017/
SHORT TERM (Today-Tuesday)...
Interesting setup early this morning with low pressure, now TD #6,
off the west coast of the Tampa Bay area with a stationary front
extending from it near the Interstate 4 corridor. Widespread rain
and a few embedded thunderstorms are occurring from just north of
stalled boundary southward and this will continue through the
morning hours as the low drifts slowly eastward toward the coast.
System is forecast by the hi-res models to move across Tampa Bay
this morning and eventually into the interior counties this
afternoon with the highest rain chances south and east of the
system generally south of Interstate 4. Locally heavy rainfall
will continue to be a possibility as bands of heavier showers and
thunderstorms develop and move onshore, especially near the coast
south of Tampa Bay, and will issue a Flood Watch for most of these
areas.
Tonight into Tuesday the system will weaken and shear out with
the deepest moisture across the southern Florida peninsula.
Isolated to scattered convection will continue tonight especially
across southwest Florida where winds will remain out of the
southwest with convection over the coastal waters possibly moving
onshore. On Tuesday the boundary will continue to linger across
the central peninsula with scattered to numerous showers and
thunderstorms developing with best chances over the interior and
south.
MID TERM/LONG TERM (Tuesday Night-Sunday)...
A stalled frontal boundary with a weak area of low pressure along
the boundary will be lifting out to the NE at the start of the
period as high pressure builds in across south Florida. The high
pressure ridge axis will gradually lift north across central and
then northern Florida for Thursday through Friday, and then remains
north of the area through Sunday. SW flow will turn to the SE and E
as the ridge axis builds in and then lifts north. Deep moisture
remains across the area through the period with scattered to
numerous showers and thunderstorms possible. Temperatures will be in
the 70s to near 80 along the coast for lows, and in the upper 80s to
lower 90s for highs.
AVIATION...
VFR conditions are generally expected to prevail outside of any
showers and thunderstorms which will cause MVFR/local IFR
conditions. Convection could also produce some brief strong
gusty winds up to around 35 knots.
MARINE...
Breezy winds around the low pressure in the eastern gulf will
continue today with small craft advisory conditions expected.
Winds and seas will diminish some later today and tonight as the
low moves over the peninsula and weakens. The boundary will
linger across the waters Tuesday then begin for lift north during
midweek with a more south to southwest flow setting up across the
waters.
FIRE WEATHER...
No fire weather concerns for the upcoming week with ample tropical
moisture in place along with rather high rain chances.
