Week 1 Day 3 Wrap Up and Feedback

We had another busy day yesterday with a tornado warning over us during operations! Feedback from the day is posted below:

ABI and All-Sky LAP

CAPE as usual seemed to be lower than it should
Where there was clear air it seemed to get a good retrieval but the area where the GFS retrieval is
taking over is scattered and pixely

Shows a blank screen every hour on the hour when there is no retrieval

DMWs analyzed the jet well with the diffluence aloft where the convection was firing

Could see the lower level winds start to back as the evening wore on just as surface winds started to
back

Can’t really use the day cloud phase for monitoring storm top features since the Vis gets washed out

Getting RGB application labels built into AWIPS would be nice to mouse over for labeling of what is
represented in the RGB similar to the radar Hydrometeor classification.

Would prefer to see the actual readout from the channels on RGB instead of a number from 0-255

CI

Probabilities ramped up all over the place really but wasn’t specific to the location

Seemed overly sensitive and jumped around a lot

Wasn’t used a lot due to a couple of known issues being worked

NUCAPS

A fix was put in that every green point will at least have a surface moderation if the rest of the algorithm
doesn’t modify the profile

Gridded product hasn’t gotten much use due to a large number of clouds in the area throughout the day

Compared the profiles to the special Norman sounding and it didn’t pick up the inversion or the EML as
well as what was present

700mb temps seemed to match pretty well compared to RAP analysis to monitor CAP strength across
the area

ProbSevere

Preference for the all hazards and for ProbTor to be on the same display

ProbWind seemed to be high (80 - 90%) across much of the time when the line was sub severe

Some kind of velocity information would be useful for wind information

Probabilities lagged slightly behind the base data analysis for a couple of storms in Kansas

Might be useful to highlight areas of maximum Az shear in line segments after reaching a certain
thresholds based on distance from radar

As storms were splitting the contour would highlight both storms and cause confidence to be lost for
those splitting storms

GLM

It was difficult to determine which lightning cores correlated to which storms in the radar

It would be better to have a cumulative 5 minute product that updates every minute to better see trends
and relate to the stronger cores

It was helpful to have the flash area and flash energy to help pick out the storms different behavior and
distinguish the stronger updrafts from weaker updrafts

It would be most useful to be able to get these products into one product to be able to be used by a
forecaster

Having useful examples for training will be helpful
