The Washington Post provides additional summary information

Yesterday’s Stormy Situation

Headlining yesterday’s stormy weather were the tornadoes that struck Charles and Prince George’s County. hour. The National Weather Service buy canada goose jacket cheap (NWS) provides a detailed account of the tornadoes’ evolution, intensity and damage in a. The Washington Post provides additional summary information and a video detailing the damage.

At exactly the wrong time yesterday, the NWS’s canada goose deals doppler radar for our region due to “hardware failure.” The NWS uses this radar to detect rotating thunderstorms capable of producing tornadoes. The NWS has access to other radars but I wonder if the problems it had with its radar might explain why tornado warnings were not issued for this storm.

Because of the localized nature of the heavy rain yesterday, totals were quite variable across the region. Reagan National recorded 1.4″ 2018 canada goose outlet of rain, but Baltimore Washington International got just 0.65″. Dulles Airport was the winner among the three local airports, measuring 2.9″ of rain, canada goose replica a new record for the date (shattering the previous record of just 0.46″). Most locations, according to the NWS, have received 1 3″ since the rain began. How much rain fell where you live?

With canada goose clearance the deep fetch of buy canada goose jacket moisture from the southeast, Canada Goose Outlet the intermittent bands Canada Goose Coats On Sale of locally heavy rain, and cheap Canada Goose the rotation canada goose clearance sale in some of the storms (and the isolated tornadoes), it almost seemed like we were dealing with a tropical storm yesterday. But we weren’t. Yesterday’s storm, a cold core system or cut off low, had sufficiently cold air aloft for hail. You would never/seldom see Canada Goose online that with a tropical storm, which is a warm core weather system meaning Canada Goose sale the freezing level is usually too high for hail to form.

Although the NWS Doppler radars are canadian goose jacket on occasion taken down for maintenance or upgrades, an actual canada goose black friday sale hardware failure (or other unexpected downtime is quite rare). The contingency plan, as I understand it, is to use radar from neighboring NWS offices. This was pretty bad timing for the Sterling radar to Canada Goose Parka go down though, yikes.

I’m not really sure that the downed radar played into this scenario regarding the lack of the warning issued. I’ll have to go back and check, but Canada Goose Online I suspect this tornadic cell didn’t have particularly strong low canada goose outlet store locations level rotation. I also wonder if anyone was even able to see this thing, given the copious amounts of canada goose store rain that was likely in the immediate vicinity. The radar signatures were related website very canada goose similar. One of the canada goose coats tornadoes associated with that system struck the Chantilly/Dulles area.

Hail usually is not asociated with hurricanes but exceptions have been recorded. Apparently hail was observed with Hurricane Hugo both in the Dominican Republic canada goose coats on sale and in South Carolina. This would be highly unusual since Canada Goose Jackets Hugo was a well organized warm core system. (It is possible that large hailstones formed at very high levels did not melt canada goose outlet toronto factory completely during their descent to earth.
