Stubborn clouds at beaches make this one of those days where the micro-climates rule.  Only a few miles inland temperatures jump from the cool 50s and 60s at the beaches to about 80 in some of the coastal valleys while the interior valleys will make a run at 100 today.

Stronger winds developing in the forecast over the Labor Day weekend. However, those winds have two impacts.  First will be to continue to cool the coastal valleys however they ill also mix out the marine clouds at the beaches in the late morning and afternoon hours. Temperatures will range from low to mid 60s at the beaches this weekend to 70s for most of the rest of the coast while interior temps hold near 100 until Monday when they quickly fall into the 80s and perhaps even the upper 70s by Tuesday.

Then a trough of low pressure swings over CA mid-week to keep temps below normal, though some warming is possible by the end of next week.

Earl has reached its greatest strength as it starts to turn up the East Coast, but probably offshore. At 8 p.m., the category 4 hurricane, positioned 520 miles SSE of Cape Hatteras, had maximum sustained winds of 140 mph. This is a very impressive hurricane as evident in its very symmetrical appearance on satellite imagery and well-defined eye.

The storm is now moving more towards the north than the northwest — which is important — because this turn reduces, but does not eliminate, the risk that the storm will come ashore on the North Carolina Outer Banks.

Hurricane Earl strengthened again into a powerful Category 4 storm on Wednesday as it headed for the North Carolina coast on the U.S. eastern seaboard, the U.S. National Hurricane Center said.

A hurricane watch was extended northwards from North Carolina up to Massachusetts, including popular resorts like Martha’s Vineyard and Nantucket.

Check out the interactive weather underground map, it has an interesting story to tell.  Click HERE to see it.

It shows interior temperatures well into the 90s, the coastal valleys in the 80s but the big story is the beaches are still in the 60s with marine clouds hanging tough.

The strength of the offshore winds were not enough to overcome a very low marine layer producing the big difference.

Valleys stay warm until the weekend, but the coastal valleys cool a bit over the next few days.
