In B at ATL now and sone moderate delays including my connection to GRR now supposedly going out half an hour late. The rebooking line down the hall hasn’t escaped the tensa barriers yet- as long as any thunder or tornado stuff holds off, they might be able to prevent a bigger cascading issue

This morning was pretty bad flying northbound to ATL - I can't imagine what we were avoiding, as we headed up the west coast of FL before sunrise. I was lying down with my belt on, wondering how much coffee must be spilling during breakfast service.

Its almost likely when you need to proactively trim a schedule (whether it be due to weather or staffing) you trim stuff that is flying on routes with multiple frequencies and where the biggest impact area will be. Someone can correct me, but a large portion of the flying through routes affected by the weather system is covered by the A319-321 and 738-9 fleet, so they're going to be more heavily impacted. And when FAA is saying arrival rates are going to be decreased, plan on only being able to do 5 arrivals instead of the 10 you planned to do, there is zero chance you're going to get rid of a widebody in place of a narrow body.

As a Meteorologist (with aviation wx experience), I can definitely see why they posted these waivers. And given the compounding staffing factors, they need to be giving proactive flexibility.
It's not just about the conditions at the airports themselves, but also along popular air routes. Starting with ATL tomorrow around noon, any change in arrival/departure rate from the line(s) of storms moving through will immediately trigger delays/cancellations. Throw any storms into the delicate staffing situation, and ATL could get messy. Even in DTW, the proximity to the upper level low pressure will make the environment conducive to thunderstorms.
Then on Friday, the location of the thunderstorms (a broken line stretching from PA southward) is a classic High impact situation for NYC air routes. The New York (ZNY) Center Weather Service Unit (CWSU) has already put out an advisory on this, and I can guarantee Delta Meteorology took this into account when issuing the waiver.
