Onshore east winds will continue through Fri.  This overall drier pattern than the past week will still allow for some rain.  Expect mostly coastal & beach widely scattered showers in the morning....scattered inland afternoon storms -- mainly west of I-95 & especially near/west of Highway 301.  The east winds will warm our coastal waters into at least the mid 80s -- the warmest of the summer so far.

The warm ocean water could lead to an increase in jellyfish as has been the case to the south near the beaches of Daytona & New Smyrna. In fact, check out the marks left on my lower leg after a jellyfish sting last weekend.  In the 11+ years in our ocean, I've never been stung.  Certainly not unbearable but a bit uncomfortable & especially startling when you're in the ocean(!).  Better than a shark, right?

Speaking of the ocean....dolphins have been turning up on east coast beaches -- either very sick or already dead.  The number in Maryland & Virginia has been in the hundreds.  NOAA has declared it an "Unusual Mortality Event".  There is some thought that the problem could spread down the east coast.  Click ** here ** for the story from CNN online.

A quick little explanation regarding Mon. night's "blue moon" (see photos below from Michael Blackstone & Jennifer C.).  You might have heard the expression "blue moon" when there are 2 full moons in the same month.  But apparently that phrase was coined from an incorrect interpretation of a blue moon which goes back to the 1930s.  In the "Maine Farmer's Almanac", "blue moon" is referred to as the third full moon during a season (this year it's summer) when there's 4 full moons.  This summer's full moons are (were): June 23, July 22, Aug. 20 & Sept. 19.  For a full explanation, click ** here **.

And now the myth that is "heat lightning".  If I've said it once, I've said it a thousand times: no such thing as heat lightning (see the great pic below from Brooke - Jax, W'side).  The lightning appears yellow because it's far away seen through dust & haze in the atmosphere.  If you were to drive to the source of the lightning, the color of the lightning would become the typical white caused by a thunderstorm.  Sure....the lightning occurs after a hot day, but the storms are a product of something forcing that's forcing the air upward.  This time of year that force is often times the sea breeze.  Expect more of the same just about each evening this week --  lightning visible in the western skies from Jax as heavy storms pound scattered inland areas through -- & even a little after -- sunset.
