#2 happened in the Peoria-Bloomington DMA, whose ABC affiliate has been on a 25.2 subchannel of Gray-owned heritage NBC station WEEK-25.1 for nearly the past decade (when WHOI-19 lost the affiliation to 25.2 after 63 years). Both the NBC NBA game on 25.1 and the ABC Oscar telecast on 25.2 were bumped partially for weather coverage last night--and many viewers were unhappy, to say it nicely.
This was the same TV station that had the developing Washington F4 tornado on 11/17/2013 literally overhead (while they were on the air) as it was moving toward that city after touching down in Pekin.
Here's a FB post from last night's on-duty meteorologist (Brian Walder) about the situation: https://www.facebook.com/BrianWalder25News/posts/pfbid02pPgHAhVPduR39JCQT53nms1mQMt7ztLSv2QzMN8LB8k1D31sEycS1y5EXGX2ZFz9l
Also, I didn't watch TV last night but I have seen FB reports that at least the early part of the Oscars was also bumped by my DMA's ABC stations (WICS-20.1 Springfield, also relayed on WICD-15.1 Champaign). Maybe during the warnings occurred during the red carpet show. But later all wall-to-wall weather coverage until at least the storms entered Indiana was shifted only to their "Fox Illinois" sister stations (WRSP-55.1 Springfield/WCCU-27.1 Urbana).
And our market has had an entire awards show before basically wiped out due to wall-to-wall weather before: June 14, 2015's Tony Awards broadcast on CBS was bumped entirely on our local affiliate (WCIA-3.1 Champaign/WCIX-49.2 Springfield) due to wall-to-wall weather threatening at least the Champaign area. Springfield viewers were not happy, to put it lightly.
