During the first part of today's afternoon briefing for the EWP, we discussed the use of the UWCI and OTTC products from the 2130-2300 UTC time period. Below is the main points brought up in the discussion...
OVERALL
Products are provided as images within AWIPS. Image combine dims visible and makes hard to see. Would be nice to have something different... would be better to load a contoured fields... "I want to have as many things loaded on one screen as possible and I can turn them on and off... I had to use 3 panels to display the products and that's not good." (We did this for NAWIPS at SPC last year and is now on the todo list for AWIPS this year)
UWCI and CTC
CI vs CTC... bias towards one?... Liked CTC better... picked up about 15 minutes before radar and better discriminated areas of interest... showed more signal than CI.
Are you ok with more false alarms?... "As long as forecasters are trained, false alarms are not a problem. Even with CI itself... make it less stringent. I can tell if cirrus is over top of it. I know why you're doing it, but maybe you don't have to go as far."
"Is the anyway to have the CI continue to track a vertically developing cloud to see if the development continues?" (This is under development within WDSSII)
Forecaster mentioned that he used the UW-CIMSS CI phone application this morning... He had good impressions and would like to see that sort of display in AWIPS (similar to the "OVERALL" discussion)
OTTC
"I could make out that it was an OT before it could... about 30 minutes before. I guess this was because of the coarse grid, but by the time an OT was detected I already had a hook echo with a tornado on the ground."
We showed the 24-hour detections of overshoots and thermal couplets. The thermal couplets were much more confined to severe areas and the overshoots were much more widespread and matched with areas of CG activity, but both seemed to lag occurrence of severe weather.
