Verification: Updated storm reports

Here are the NSSL(top), SSEO_0000 (middle), and SSEO_1200 (bottom) plots showing the model reports overlaid with the observed reports so far. The SSEO lacks hail and wind. Red dots indicate current observed storm reports. Black contours can be compared directly to he shaded model fields. The ensemble plots have 7 and 4 members, respectively. All go through 1200 UTC tomorrow morning.

UPDATE 1: I have rerun the graphics and they are displayed below.
NSSL-WRF (only looking at the top panel of "test") compares favorably to the observations, at least in this smoothed representation. It does appear to be shifted too far east and south (the slight offset in the outer contours relative to the shading). But it did not capture the concentrated area of tornadoes in central KS. Despite "looking good" I think the skill scores would be somewhat low. I will try to run the numbers this week for all the models displayed so that each individual model can be compared and we can see which one, if any, stood out from the pack.


The SSEO ensembles are below:
