Ring of Fire Derecho – travelled 600 miles from Iowa to D.C.

On Friday, a historic, record-setting heat wave covered a sprawling region from the Midwest to the Southeast. All-time high temperatures records of 109 were established in Nashville and Columbia, South, Carolina and tied in Raleigh and Charlotte which hit 105 and 104. Here in Washington, D.C., the mercury climbed to an astonishing 104 degrees (breaking the previous record set in 1874 and 2011 by two degrees), our hottest June day in 142 years of records.

 

 

…the coverage and availability of this heat energy was vast, sustaining the storms on their 600 mile northwest to southeast traverse. The storms continually ingested the hot, humid air and expelled it in violent downdrafts – crashing into the ground at high speeds and spreading out, sometimes accelerating further.

Peak wind gusts in the D.C. region include the following:

71 mph near Dulles Airport
70 mph in Damascus, Md.
79 mph in Reston, Va.
65 mph in Rockville, Md.
70 mph at Reagan National Airport
76 mph in Seat Pleasant, Md. (Prince George’s co.)
77 mph in Swan Point, Md. (Charles co.)
70 mph in Ashburn, Va.
69 mph in Leesburg, Va.

In addition, an 80 mph gust was clocked in Fredericksburg. To the north and west, 91 mph and 72 mph gusts were measured in Ft. Wayne, Indiana and Columbus, Ohio

‘Ring of Fire’ – solar eclipse coming this Sunday

There will be a stunning partial solar eclipse on Sunday, May 20th. The moon will begin shrouding the sun at 5:27 p.m. (PST) and will cover 83 percent of the sun’s surface at 6:40 p.m. The eclipse will take place while the sun is sinking toward the horizon, out over the ocean. It’ll be easy to see, if skies are clear.

Do not — repeat, do not — look at the eclipse with your naked eye or with materials that don’t protect your vision from UV and infrared radiation. You risk permanent and serious damage to your vision if you don’t use the proper safety equipment to view a solar eclipse, and the damage can occur within seconds.
