EWP Week 2 End of Day 4...Thoughts and Feedback

Our forecasters ended the day in the Omaha, NE and Sioux Falls, SD offices.  Storms developed during the afternoon hours over far northeastern NE, southeastern SD and western IA.
  • ·       GOES-16 ABI Imagery and products (Imagery/Derived/Channel Differences/RGB Composites)

o   Played with Channel 1-15…was able to see the difference in temperatures for 13,14,15
o   Fire products did really well, especially with the fire over North Carolina, really popped out
o   Need help sheets, some case studies
o   Change the naming convention of the RGB products
o   Wouldn’t hurt to spend an hour at the beginning on each week going through the RGB images
o   Check the sampling in AWIPS, make sure they are correct
  • ·       GLM

o   Storms that spiked on the gridded data drew attention to storms, still hard to look at the point and be able to notice trends
o   Like the color table with the bright yellows and reds really differentiating the storms that needed to be watched
o   Excited because it’s going to cover some areas we don’t have current coverage for, and good for public safety
o   For training, open up with some case studies, capture the attention of the forecaster
o   Confusion about the difference between groups, events and flashes…need to create a good conceptual model…what is actually happening in the storm?
  • ·       NUCAPS

o   Point soundings were useful, matched the environment
o   Gridded data weren’t coming across well in AWIPS, things were missing
o   Liked to look at the gridded data for higher areas of CAPE and the pick the point sounding near that area
o   Didn’t play with the cross sections, but think they will be valuable for forecasting
o   Need to improve latency
o   Needs to be a way to know which point was clicked, an identifier besides latitude and longitude
o   Since the MetOps come in sooner, they might be more helpful if they were operational
  • ·       ProbSevere

o   Trends were so much more important than anything
o   ProbHail was really accurate
o   ProbWind seemed to really catch high wind values where it was most expected
o   Would like a way to look at threats as individual layers, maybe a four panel…since some days certain threats are more predominant than others
o   ProbTor wasn’t as good when storms morphed together into larger ProbSevere objects
o   Saw high azimuthal shear values, but ProbTor value was low

o   Like the contouring
