Update
Deep layer ridging prevails this morning from the western gulf of
mexico through the southeast conus. The ridging will remain
firmly in place over the next several days, resulting in dry and
subsident conditions across south florida. The 23.12z mfl sounding
sampled this environment quite nicely, with a precipitable water
value of only 1.07 inches. This value is around the 10th
percentile for today based upon climatology. Look for easterly
winds to pick up for this afternoon and evening in response to a
tightening pressure gradient between the atlantic ridge and a low
pressure trough over the caribbean sea. This burst of wind is
meaningful in the following ways to our forecast:
1) it will increase the risk for rip currents markedly for the
atlantic beaches starting this afternoon. A high risk for rip
currents will develop, with this threat lasting through the
memorial day weekend.

2) it will create hazardous, near small craft advisory, conditions
for the atlantic waters through at least tonight.

Given this, and projected wind and wave output, opted to extend
the rip current statement through Monday given the relatively high
confidence in hazardous conditions continuing.

Mariners should also use caution today (especially small craft)
given the higher burst of winds expected for this afternoon and
evening.

Beach forecast
Strong onshore winds will create a high risk for rip currents on
the atlantic beaches through Monday. Swimmers and others in the
water should heed the advice of lifeguards, beach patrol flags,
and signs.

short term (today through Saturday)
high pressure will continue to dominate into the weekend. At the
surface, ridge will build in from north and east, keeping dry
conditions in place and leading to breezy east wind. These winds
will moderate temperatures a bit on the east coast, but allow for
above normal maxima over southwest florida. Cant rule out very
isolated atlantic showers today, but pop is less than 15 percent
and any shower should be brief. Thereafter, deeper dry air arrives
and any precipitation should be shunted well to the south of the
area.

Long term (Saturday night through Wednesday)
deep layer ridging will keep any weather systems from impacting
the florida peninsula through at least the middle of next week.

Breezy east wind will continue. Models have backed off on the
arrival of modest moisture return early in the week, so have
bumped down rain chances to below 20 percent. Temperatures are
expected to gradually creep up through the period, with western
areas approaching high temperatures in the mid 90s and maxima in
across the east coast urban areas flirting with 90f. Lows will
mainly be in the 70s.

Marine...

east wind has increased overnight to near small craft advisory
levels, and speeds just below 20 knots are likely through at least
Friday as high pressure centered north and east of the region. For
now will hold off on headlines but this will be monitored closely.

The breezy conditions will likely continue through the holiday
weekend, with atlantic seas reaching 4 to 6 feet.

Beach forecast...

with east wind increasing through the day, a high risk of rip
currents exists on atlantic beaches through at least Friday night.

With the breeze likely continuing through the holiday weekend, the
significant threat of rip currents will also likely persist on
atlantic beaches into early next week.

Climate...

a daily record warm high temperature was tied at naples
yesterday, with 93 degrees tying the record last set in 2015.

Additional record highs are possible at naples into the weekend.
