Welcome Kansas. Welcome to Nebraska. Welcome to South Dakota?




No.

(that was not as painful to write as I thought...after an extended period of mourning...).

After a long ferry from Edmond, OK to Colby, KS on Thursday (?), late (tornado-less) operations near Scottsbluff, NE on Friday (most groups did not make it to the hotel until 130 AM or so), Vortex2 decided that Saturday was a down day.

By all accounts, the weather set-up yesterday had its deficiencies...there was not a definitive region where good shear (wind profiles that favor rotating thunderstorms) and good CAPE (Convective Available Potential Energy; the energy needed to fuel vigorous thunderstorms) overlapped. Convective initiation was questionable...

In meteorological lingo, it would take a "mesoscale accident" for conditions to be favorable for supercells.

As we all know, accidents (frequently) happen...and we did cry over our spilled milk....(I am colloquialism-ed out or is it aphorism-ed?)

Picture 1: Another postcard from the back of DOW7 (a coffee table book is in the works). "Greetings from Scottsbluff, NE!"

We did get a chance to review our data...(the silver lining--one more!)
The left side of these images show precipitation (reflectivity; pinker colors = more precipitation) and the right side shows Doppler velocity (cool colors indicate motion towards the radar and warm colors indicate motion away from the radar)

Picture 2: This is data from DOW(?) on 12 May 2010 showing a weak tornado near Clinton, OK.

Picture 3: More data from DOW(?) showing a BWER (bound weak echo region, of course!) on 12 May 2010. The BWER is a precipitation-free hole, indicating a strong updraft.

  2. Anonymous is a jackass. Did she say anything about mis-forcasting Saturday? Post with your real name or shut the hell up.
