SE Nebraska
Just an interesting note: Although instability is somewhat weaker into Southeast Nebraska, any storms with the staying power to make it into the FBY, BIE, LNK area, have extremely favorable low level shear, arguably moreso than across Eastern Kansas.
Latest SFC obs indicate Almost due East winds across the area while the FBY profiler shows 30 kts from 180 degrees at 1 km, 30 kts from 210 degrees at 1.5 km, and 60 kts from 210 degrees at 2 km!
Also, recent low topped line segment intensified out of nowhere east of LNK. Perhaps there is more instability in the area than one thought.
Edit: Said line segment seems to be developing a couplet northeast of LNK at the 1.5 and 2.5 SRM images out of OAX.
Further Edit: As storms approach the cold front, they have taken on more elevated characteristics, and any couplet once present has since weekend with northward movement
