Heat wave builds at inland locations today...

Near record heat and increasing wildfire danger this weekend
and next week...

Update
Strong high pressure centered over south ga will remain in place
today with hot and dry conds continuing. MAX temps will reach into
the mid upper 90s inland, lower 90s along i-95 corridor and mid to
upper 80s at the beaches as the east coast sea breeze develops
early this afternoon and pushes inland to about the us 301
corridor by late in the day. Due to dewpoints in the 60s, heat
indices will be close to or only slightly above actual temps, so
will likely peak out close to 100 degrees this afternoon.

Early morning satellite images show the smoke associated with the
yellow bluff road wildfire remains very close to the fire location
and not widespread enough to support dense smoke advisory, so will
likely replace with special weather statement (spsjax) to continue
the threat of patchy dense smoke and irritants due to smoke in the
vicinity of the wildfire location. Expect the east coast sea
breeze to reach the fire location by 2pm with east winds around 10
mph with gusts to 15 mph at times through the rest of the
afternoon and early evening hours.

Aviation
Vfr through the period with local smoke issues possible in the
vicinity of the jax terminal due to the yellow bluff rd wildfire.

Marine
Rip currents: marginal moderate rip current risk at the beaches
today with morning surf breakers around 2 feet and e-se sea breeze
expected this afternoon.

Fire weather
Elevated concern for wildfire outbreaks this holiday weekend due
to increased outdoor activity including fireworks, camp fires,
cigarettes and cookouts.

An extended period of hot and dry weather through early june will
continue elevated fire danger, despite not meeting locally defined
"red flag" criteria. Temperatures will warm into the upper 90s to
mid 100s inland each day with afternoon humidity ranging between
25-35%. Winds will be mainly local terrain influenced, with daily
sea breezes, river breezes and lake breezes. Gusts 14-18 mph will
be possible as the east coast sea breezes develops and presses
inland each afternoon. Dense smoke advisories will likely continue
through the weekend associated with the yellow bluff wildfire in
north-central duval south-central nassau counties.

Climate
Record highs at climate sites for memorial day weekend:

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.
