May 8 Derecho Aftermath (18 confirmed tornadoes)

#1 Postby brunota2003 » Fri May 08, 2009 6:04 pm

While we normally keep everything in the same thread, I am afraid with the derecho poised to continue on into this evening and possibly even tonight, much of the information or pictures currently available could be buried underneath multiple pages of warnings, radar images, etc...this is strictly for post storm recovery, and post storm talks.

Apparently, this storm had sustained winds of 70 mph (measured prior to anemometer failing), if not higher, with a measured gust of 106 mph!

"Peak wind gusts were measured around 80 mph at several locations, including DuQuoin in Perry County and Carbondale in Jackson County. The peak gust recorded by the automated system at the Carbondale airport was 81 mph before the system failed. An observer at the airport visually observed a separate anemometer located on the rooftop reach 106 mph. The automated system measured a sustained wind of 68 mph before failing."

Here are NWS links so far:
Paducah, KY NWS (with an impressive radar picture)

Springfield, MO NWS:

I also ask, since many have been calling this a landcane, are there any obs available from the passage of the "cane"? I am curious as to the wind shifts, and what the temperature did...I am quite sure the temperature decreased as the "center" approached, as in a typical cold cored system, but hey, I can be curious right?

With that data, it was basically a Category 1 hurricane moving at 60 mph over land...

So far, the two NWS offices above (see first post for links) has confirmed 14 tornadoes, one of which was an EF-3.

Thus far:
EF-0: 3
EF-1: 6
EF-2: 4
EF-3: 1
EF-4: 0
EF-5: 0

EDIT:

Also, new page out from NWS Wichita, KS:
http://www.crh.noaa.gov/news/display_cm ... 8&source=0

Just found these tornadoes:
http://www.crh.noaa.gov/news/display_cm ... 4&source=0 (EF-1 Louisville, KY NWS)
http://www.crh.noaa.gov/news/display_cm ... 0&source=0 (EF-3 Louisville, KY NWS)
http://www.erh.noaa.gov/rnk/events/2009 ... mmary.html (EF-2 and EF-1 Blacksburg, VA NWS)

So with those accounted for, the new totals are:

EF-0: 3
EF-1: 8
EF-2: 5
EF-3: 2
EF-4: 0
EF-5: 0

18 tornadoes thus far, after one day of searching. What is the minimum amount to be considered as a tornado outbreak?
