It had decent G2G shear for a couple frames, but looks like it may have opened up some on the very last frame. Let's see if any reports come out of Medon, TN.

Not many tornadoes thus far (at least warning wise). Then again, this event is mostly a squall line sequence.

that line has sure gotten interesting as the night has progressed. Only a couple tornado reports so far, plenty of wind reports though

You all already know what my thoughts are on Day 4 outlooks. Our local meteos (two of them have much severe weather experience from living/working here) are not playing this up too much. But they have said make sure to get out and get a weather radio. This past week was Severe Weather Awareness week in Oklahoma, so hopefully the message has gotten out. Friday night/Saturday afternoon roll around, I'll tell you what I think.

They get all caught up in 'fancy'.This board software can be set up to disallow images over a certain file size. I'd suggest about 50K or so. It could also disallow .png and .tiff file types which are notoriously large.
