Daily Summary: Week 5, Day 3 (June 10, 2015)

Warning activities for Wednesday of Week 5 took place in the Chicago, Hastings and Rapid City CWA's. Once again, significant convective activity was not present in any of the LMA's, so PGLM products were not able to receive an evaluation.

- Bill Line, SPC/HWT Satellite Liaison

GOES-R LAP
- Absolute values of CAPE were way off when compared to RAP, SPC mesoanalysis, RAOBS

NUCAPS
- Finer details would still be nice to see in the profiles

GOES-R CI
- Mid to high clouds obscured development in Chicago
- Once developing convection broke through the mid-level cloud deck, 80—90 % probabilities appeared
- Didn’t get many signals today in the Hastings CWA, so wasn’t useful. Thin cirrus were present

ProbSevere
- Our storms were so explosive, once it got close to 50, we would warn from radar because it was going so fast
- I like how if you’re focusing in on one cell (with a feeder band), watching outflow interaction, and then another cell developed nearby. It keeps you aware that you should go look at that now
- Especially valuable when you have lots of stuff on radar
- I could see it being on a SA panel
- Storm coordinator could use to make sure all relevant storms are covered
- I was looking at a storm that was weakening, so I focused my attention elsewhere… looked back a little later and saw the weakening storm was back to 80, telling me that I better take another look … good SA
- If you can’t look at all tilts, its seeing column for you
- New storm popped up when we were focused on other storms; this flagged us, quickly put severe on it
- Towards end of day, outflow boundaries collided, immediately flagged it to pink, then collapsed

SRSOR and 1-min OTD
- In Chicago, you could see where the front was and where cu were developing under a mid level cloud deck. Could see CI as it was occurring below those clouds.
- With new cells forming under cirrus canopy, you could see it bubble right through the anvil blowoff
- Saw outflow on w edge of convection
- Better anticipate where new stuff will develop
- Draws me to an area of new updrafts, where should I look
- No question – I will have it loaded when in warning situations, keeping an eye on it
- Good situational awareness display to have the 1min loop loaded
- For training, it would be most helpful to see examples of various phenomenon from the folks who have already been using the data
- As storms were developing, a feeder band was being ingested into the main cell, we were watching it for new development, and stuff did develop along it. Wouldn’t have seen it quite as well with 15 min data

Lightning jump
- Used with probsevere
- Stuff going from nothing to severe fast. 8sigma jump noted
- Sometimes I miss significant jumps
- We would like this to be incorporated into probsevere
