Fog, Day 10

We've had such a sequence of amazinghly warm days that perhaps we are starting to take it all this straneness for granted.

Based on the period of record, these temperatures are borderline incredible, but we would have to conclude that this siege of fog as it least as extraordinary as the warmth.

As we mentioned in a post yesterday, March is not the fog season. It is the windiest month of the year, and wind ordinarily is the mortal enemy of fog.

On average, March has only one day of dense fog, defined as a ground cloud so thick that it cuts visibility to a quarter-mile or less.

This month it's happened three time. At Philadelphia International Airport this morning, visibility fell to 0.13 miles.

As Bob Wanton at the National Weather Service in Mount Holly yesterday, the fog is rolling in on weak onshore winds. Strong enough to import maritime air, but too weak to send it on its way.

Chances are that without these morning clouds, the daytime temperatures would be even higher.

We make note of this because yesterday we received a call from our son near Burlington, Vermont, and he reported temperatures in the 80s.

We dismissed this as an hallucinatory experience attributable to youthful exuberance.

We may never doubt him again. The high yesterday in Burlington was an astronomical 81 -- 13 degrees above the old record.

At nearby Mount Mansfield, the highest peak in the Green Mountains, it got up to 64, beating the old record by 14 degrees.

As for around here, we should see a cooling off with some rain that the prematurely burgeoning foliage should appreciate.

But those who have been around for awhile might remember that on this date in 1958 the region was cleaning up from a three-day winter storm that remains one of the most damaging on record. So savor these April and May intrusions.

In the meantime, if Carl Sandburg was right, and fog really does arrive on little cat's feet, the cat must like it here.
