Strong Inversion

This is a good one: 3pm Wednesday, almost 25F degree inversion in the lowest 100 meters. Clear skies. But the sun was shining at 3pm, which is 20 minutes later than on Solstice.

This is be increasingly the case: starting over the weekend all models are building a massive high aloft over NW Alaska, which this time of year is a good way to create very steep inversions.
