FedEx Invisible Winter storms In Buffalo and Memphis Cause FedEx Delays!!! Not reported by any Weather Agency! Nationwide

I shipped a package from Bethesda, MD 20814 to Buffalo NY 14215, using the FedEx 2Day AM Delivery service.  My package was shipped on 12/18, and was guaranteed to be delivered on 12/20 before 10:30 am. The package was not delivered on time.

On 12/20 at 8:21 pm I tracked my package.  The last posted event was that it had arrived at Newark, NJ at 9:01 am on 12/19. There is no estimated delivery date.

Frustrated that the FedEx customer service representative had lied to me about severe weather in Buffalo, NY, I called FedEx again.  This time I spoke to a customer service representative who told me that the weather delay had actually taken place in Rockville, MD and/or Dulles, VA prior to the package arriving in Newark, NJ.  I checked the weather in Rockville, MD and Dulles, VA between 12/18-12/19. There was no precipitation during this time and visibility was clear.

(*Side note*  even if weather had impacted the shipment of my package from MD to NJ, FedEx had a full 25.5 hours to transport the package from Newark, NJ to Buffalo, NY and to still get it there on time! ..you'd think this would be an easy feat for a company specializing in express deliveries?)

Rant aside, I called and spoke with one more customer service representative. I informed him that I would be lodging a complaint if I did not receive accurate information regarding the weather delay impacting my shipment.  He informed me that there had been two inches of snow in Memphis Tennessee (The FedEx Hub) and that this storm had affected all express shipments, because all express packages fly through this central hub. I asked him specifically when this snow had fallen and he told me Thursday, and I verified that he meant yesterday, Thursday 12/19.  ...so I checked the weather in Memphis, TN on 12/19.  There was no precipitation!  (There was no precipitation in Memphis, TN on 12/18 either...or 12/17, 12/16, 12/15 or 12/14.  It did rain on 12/13.)
