952 am edt Mon jul 23 2018

Synopsis
A complex and very non-july weather pattern remains in place across
the country this morning, with a large ridge over the west and
troughing over the east. This troughing extends southward across
florida, with a cyclonic flow in place over the region and multiple
shortwaves rotating around its base. At the surface, broad low
pressure sits over the southeast, with a low-level southwest flow in
place across the local area.

Short term (today-Tuesday)
The severe weather we had earlier this morning across parts of the
tampa bay region has come to an end and has likely helped stabilize
the atmosphere at least for the next several hours, so we are likely
to see a mostly dry morning with the exception of a few stray showers
here and there. Once we get into the afternoon hours, a more typical
southwest flow pattern will set up, with showers and thunderstorms
developing over the gulf and then moving inland. Some relatively
drier air looks to wrap southward over the northern half of the
forecast area (from around i-4 northward) for this afternoon, so
expect less overall coverage for these locations. Will also have to
keep an eye on the potential for a few strong storms this afternoon,
mainly south of the i-4 corridor, but this potential looks to be less
than yesterday. Once we get past 4-5 pm or so, most of the convection
should be toward the other coast and we should again have a period of
dry weather for most locations. This will be short-lived, however, as
more shortwave energy wraps around the trough and we get more showers
and storms re-developing over the gulf. Hi-res guidance this morning
has been consistently showing this and so will keep a chance for
rain in the forecast for the coast through the overnight period for
now, and re-evaluate through the day. Then tomorrow afternoon, this
activity will work its way inland, similar to what we are expecting
today.

Long term (Tuesday night-Monday)
The persistent mid upper-level trough over the eastern part of the
country finally lifts out Wednesday into Thursday as a strong closed
low swings over southern canada and ridging builds in over florida
from the east. This ridge will generally hold over the state through
the upcoming weekend and into early next week even as troughing
starts to try and build back over the southeast next Monday. At the
surface, the atlantic subtropical ridge will build back south of the
state Wednesday into Thursday before shifting north for Friday and
into next week. These changes will put us back into a more typical
florida july pattern. Wednesday and Thursday, we will still be in a
southwest flow, so showers and storms can be expected over the gulf
during the early morning hours and then most activity will shift
inland through the afternoon and evening. As the ridge axis shifts
northward starting Friday, winds will be lighter and more variable,
allowing the sea breeze circulations to dominate.

Aviation
A few stray showers will be possible through the rest of the morning,
but conditions should otherwise remain dry until this afternoon.

There remains a higher degree of uncertainty with the thunderstorm
forecast for the rest of the day, but with a southwest flow in place,
we should see some additional activity pop up over the gulf early
this afternoon and then move inland, so will keep vcts mention for
all sites. There could be a break in storms later this afternoon and
evening, but then another round is expected overnight over the gulf
and possibly affecting coastal terminals. Winds will continue out of
the southwest through much of the rest of the day, with some gusts to
20 knots or so possible.

Marine
Winds of 15 to 20 mph persist across the waters from around venice
southward this morning, with lighter winds elsewhere. Seas are around
4 to 6 feet. Winds will slacken some through the rest of the day as
the pressure gradient starts to relax. Winds will remain out of the
southwest through mid to late week, with no further headlines
expected at this time. Scattered to numerous showers and
thunderstorms will generate rough seas and strong winds through the
next few days.
