954 am edt Sat aug 18 2018

Update
Isolated atlantic showers are spreading toward the coast and will
increase in coverage this afternoon as sea breeze spreads inland.

Guidance is not overly enthused with convection anywhere but
western interior, and 12z RAOB analysis doesn't appear to reveal
air mass too favorable for intense convection. Thus, considering
that gulf atlantic sea breezes in easterly flow regime should
collide over western interior, have maintained high pops and
potential for strong downburst winds in this area. Otherwise,
expect near normal temperatures reaching around 90 degrees for
maxima.

Climate
Fort lauderdale's low temperature yesterday august 17 was only
83 degrees, which tied the daily record warm minimum, last set in
2013. Rainfall this morning cooled fort lauderdale such that no
records were threatened today.

Prev discussion issued 831 am edt Sat aug 18 2018
aviation...

guidance suggests most activity will develop over or just inland
of east coast terminals midday and then spread westward, thus
will maintain only vcsh this afternoon, not vcts. Better chance
will occur at kapf where gulf sea-breeze intrusion will be impeded
by easterly flow. Expect ese flow 10 kt during the day and
light calm overnight.

Beach forecast...

east southeast onshore flow will create a moderate risk of rip
currents on atlantic beaches today.

Prev discussion... Issued 421 am edt Sat aug 18 2018
discussion...

latest water vapor imagery loop indicates an area of dry air in
the mid and upper levels stretching from central florida eastward
towards bermuda. This dry sinking air is associated with a rather
strong 594 mb high pressure cell. Clockwise motion around this
feature has allowed for persistent easterly flow to southern
florida overnight. A distinct tongue of moisture can be observed
on satellite derived pwat stretching from the northern keys
eastward toward the bahamas with values greater than 2.0". As
this area of enhanced moisture slowly edges towards our cwa, the
threat of precipitation will steadily increase. The GFS progs a
rather compact vort MAX to develop this afternoon near the
straights and move over the everglades. As this feature
approaches, 500 mb temps drop to -8 or -9 c. Deeper moisture and
greater instability, compared to the last several days, should
bring a greater coverage of mainly afternoon and evening
thunderstorms. Some of the storms could become strong, producing
downdraft winds in excess of 45 mph. Small hail will also be
possible due to the colder than normal air aloft, especially over
the western interior and southern portions of miami-dade county.

Maximum temperatures are forecast in the upper 80s to near 90
along the coasts with low 90s forecast elsewhere. These values are
a degree or two below normal for this time of year.

Late this weekend through mid next week the synoptic pattern does
not budge much. High pressure over the western atlantic will
continue to bring easterly or southeasterly flow into south
florida, driving deep moisture and instability over the area.

Similar to previous days, there will be an elevated threat of
mainly afternoon evening convection over the interior and gulf
coast. Showers and thunderstorms will also be possible along the
east coast metro region, but definitely more isolated.

Temperatures each afternoon should reach near 90 degrees along the
coast and low 90s for the interior.

Marine...

high pressure across the western atlantic will
prevail through early next week. Moderate east to southeasterly
flow will continue across the local waters with favorable boating
conditions. Scattered showers and thunderstorms are possible
each day. Winds and waves could be higher in and around any
shower or thunderstorm.

Aviation...

convection continues pushing ashore from the atlantic this
morning. Expect mostlyVFR with brief bouts of sub-vfr. Additional
convection possible through the morning into the afternoon with
the highest storm coverage expected to the interior of the
terminals. Apf should see a diurnal sea breeze pattern with the
threat of storms again as well. Short-fused amendments will likely
be necessary.
