I've had some very foggy days this week too, (fortunately, i don't have to drive, i take a commuter railroad to work,) but as i pass by one of the salt marshes, the fog is a soft mantle of white, drifting across the waters..
the same weather system that is causing the fog in NYC is a front of low pressure, that extents south, and west.. the curved line of this slow moving front extents from south and west of Richmond VA, all the away up to Boston.. it is moving slowly north and east, and i suspect WW, will have heavy thundershowers, tonight, or early tomorrow, they are expecpect to pass through NY about 5 PM tomorrow. and boston early saturday..
the low is filled with hot moist air up from the gulf of mexico, and behind it is a high pressure system the thunderstorms are a 'squall line' where the two systems meet.
skys today are clear blue and cloudless. and some of the fog is radiation fog.. but almost none is evaporation.. we are in the midst of a 17 month drought, and i wish the ground was cool and moist. We (NY) had normal rain fall for the month of MAY, but this is there first time since september 2000! NY and NJ reservois are all way below normal. (NY are at about 81%, not flush from winter run off and at 100%--as they should be.) NJ is in worse shape. the local EPA office is working with city and state agencies to raise public awareness of poor water uses, and to come up with solutions to save water.
the WTC site ate up thousands of gallons.. the fires there burned from sept 11 to November! and the dust from the clean up requires that the city use water trucks to wash down the street (now only 2 times aday, but for months, 4 or more times.)
A Little Foggy
