Brian Brettschneider just posted an ERSI image of what he says is the warmest high temperature for the Alaska Arctic Coast - 84F at Deadhorse this afternoon. He says, "The new all-time record of 84°F at Deadhorse is also an AK record for any station within 50 miles of Arctic Ocean."

However, this is not the only 80+F temp on the coast this afternoon, or even a high of 84F. Brian posted an earlier shot with 84F at Alpine, AK which reached that temp at 3:45 pm this afternoon, followed by Deadhorse at 4:53 pm.

What's crazy is that it is warmer there than in some Florida locations this afternoon and 3F warmer than my mid-America location!

It's what is coming that shows how out of balance the Arctic is right now. A strong cold front is to cross the coast near Wainwright and Barrow by Friday. The Barrow, AK statement reads:

Now think about the impact on the thinning Arctic sea ice. It is going to experience an area expansion due to 20-25 mph winds, with seas high enough to call for a small craft advisory,
all with sea surface temperatures well above normal.

Areas in white represent sea ice presence, but with thin concentration.
