More records washed away
The persistent rainfall has washed away more weather records across the region. Washington's Reagan National Airport yesterday set a new mark for a June 26. The capital's landing strip reported an impressive 4.22 inches for the date. That demolished the old record of 2.62 inches set on the same date in 1942.
Dulles International Airport also posted a record, although not nearly as impressive. Instruments there recorded 1.92 inches of rain on Monday, edging out the old record of 1.91 inches, set in 1978.
There was no new record yesterday at BWI-Marshall, where the rain gauge collected 0.83 inch. Sunday's rain there did set a new mark for the date - 2.75 inches, busting the old record of 1.95 inches, set in 1872. Another 19th-century record bites the dust.
The impact of all this rain is all around to see. But sometimes it helps to see the havoc in writing. Here's one of the longest storm reports I can remember from the National Weather Service at Sterling.
Today, the rain train appears to have moved west of our region, as the big high-pressure system out over the North Atlantic - the roadblock that has prevented the misery from moving off shore - has edged west. Meteorologists call it "regression." Weather systems in these parts aren't supposed to move east to west. Here's a nice radar loop that shows where the worst of the rain went. Looks like a bit of rain this morning out on the beaches.
And to top it all off, the National Hurricane Center is watching for signs of organization in a broad region of low pressure off the Southeast coast. Whether it starts to rotate or not, the weather maker promises a new load of moisture for the Carolinas. Here's a fairly amazing satellite loop showing the northward flow of Atlantic moisture that has been soaking our basements, and the strengthening of that low off the South Carolina coast.
