I was only able to see the last half hour or so, but I was really impressed. All weather (kinda like old TWC) in a fresh way. Dave's segment was great, Sarah is decent on TV, and the set actually looks good. Frankly, I didn't mind the longform format; the locals are so crappy nowadays, and most of the info is in the LDL.
This should be in primetime. They could've easily done 7-9, and kept the same WCL shifts of 10-1, 1-4, 4-7. If the ratings were good, I wonder if a third hour could be in the cards. Too bad they're seemingly allergic to doing live weather in primetime.
