Dry andVFR conditions will prevail throughout the period as skies
continue to clear behind the front. Latest model guidance shows
the east coast sea breeze moving into all the east coast
terminals. Therefore, have included a wind shift later this
afternoon to the sse. Tonight winds will return to the wnw and
diminish.

update...

dry and clearing skies behind a cold front that moved through the
area yesterday evening and overnight. The front has now pushed
off the SE coast and over the atlantic waters near the bahamas.

Mostly sunny skies with lower relative humidity values today. High
temps today will be in the mid 80s. No major changes to the
current forecast as benign weather conditions expected today.

Prev discussion... Issued 333 am edt Wed apr 25 2018

today and tonight: frontal boundary has been making its way through
south florida overnight, currently just around the far southern tip
of the mainland. The boundary is sparking a few showers and storms
along the east coast as it moves offshore, and while expect most
convection to remain over the atlantic, additional showers,
potentially a storm, can't be ruled out over land until the front
completely clears the peninsula.

Front should be southeast of the region by daybreak, with an
otherwise dry and partly cloudy day ahead across south florida.

Temperatures will not be as warm as Tuesday, but remain seasonably
warm in the mid to upper 80s. Lower humidities will allow cooler
overnight lows ranging from the upper 50s over the interior and mid
to upper 60s along the coasts.

Thursday: we will remain in between systems on Thursday, under the
influence of the relatively dry post-frontal airmass. High
temperatures will continue in the mid to upper 80s. Overnight lows
ranging from around 60 over the interior and mid to upper 60s along
the coasts.

Models differ a little on how quickly low level moisture begins to
return as flow backs more southwest Thursday night. However, enough
consensus is in place to keep the mention of isolated showers
creeping back into the region from the south late Thursday night,
especially over the waters.

Friday into early next week: several strong shortwaves are expected
to rotate through the northern gulf coast deep south through the
weekend, around the base of the larger east coast trough. Some model
to model inconsistencies remain, but overall it looks like these
features will drive the development of another weak surface low that
will bring another diffuse and slow moving frontal boundary through
the fl peninsula this weekend.

Over south florida, still look to see increasing moisture from south
to north Friday and Saturday as the old frontal boundary drifts back
into the region. Expect at least isolated showers across the region
both days, with coverage more scattered across miami-dade and
mainland monroe. Models are more consistent in bringing a stronger
upper level trough through the state during the day on Saturday,
which looks to bring back a drier airmass for Sunday into early next
week.

Marine... Brief northwest wind surge behind initial frontal passage
this morning will bring speeds around 10-15kts. Otherwise, expect
drier conditions and prevailing west-northwest winds around 10kts
to linger into Saturday. Speeds will be light enough to allow the
atlantic seabreeze to develop near the coast each afternoon,
bringing winds out of the south-southeast.

Another frontal passage late this weekend will bring winds out of
the east-northeast on Sunday, with increasing speeds expected as we
head into early next week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
