Working all threats on two cyclic supercells in far NE CO and far SW NE. Interesting for the forecasters dealing with velocity couplets moving in different directions as they occlude and “hand off” to the next mesocyclone.

George and Jon report they are putting more thought into their probabilities tonight now that they have the software mastered. Jon defined a threat area which showed the threat ramping up from non-severe to severe during the valid time giving some forecasting aspects to the polygon.

A First for the Testbed: Smart-R radar data available now for storm in Southern Kansas/Northern OK and Greg has loaded this into radar sources for participants. Sector is not exactly what we need but they will see if they can optimize it.

PW software giving challenges to George with regard to syncing products and threat areas. George believes operator error. Both groups keeping up with hail and wind threats as storms make their way into sw Kansas.

“Shift Change”. George now at the helm with Jon and Chris at the controls with Milovan. Rumor has it SPC on the verge of a TOR over ncentral OK. Storms have been producing giant hail and winds over 70mph. Will likely stay with these storms until end of IOP.

Splitting into 2 groups and both working storms in OK panhandle and NW OK, SW KS. George and Jon are Team 1 and Chris and Milovan are Team 2. Shave is calling on storms which are in a SVR and producing reports of golfball hail.

Liz Quoetone (EWP Weekly Coordinator, 2-6 June)

George goes with a very low prob TOR threat area, mainly to see how all these things look together. Now have hail, wind and tor threats overlapping.

Liz Quoetone (EWP Weekly Coordinator, 2-6 June)

John Ferree has arrived as another observing scientist. Team has once again rotated clockwise. Chris is on AWIPS, George at PW and Jon as assistant. Quarter hail still being reported on the storms in question.

Liz Quoetone (EWP Weekly Coordinator, 2-6 June)

Chris and George did a Warning with initial prob of 100% with no degredation for 60 minutes. They are expecting large hail for the duration of the warning.

Liz Quoetone (EWP Weekly Coordinator, 2-6 June)

Participants rotate (clockwise). Jon now on AWIPS using FSI amongst other things. Chris has the PW mouse and has opted to start up fresh to get more familiar with PW tool. George is now in assistant chair.
