This is just a guess as to what is occurring in your case. Bandwidth is distributed among all the cell sites in range of your phone. With bad weather comes power outages and cell sites have limited battery backup. Cell sites in dense populated areas may get cell techs connecting generators, but some of them will just lose power. That would mean more users sharing a smaller pool of bandwidth. If you know the debug code on your phone to display the cell sites you are connected to and you document the cell site ID's, you can probably tell when some of them vanish. On an iPhone the Field Test Mode is *3001#12345# On Android there are apps to display the Cell ID. On the older flip phones, field test mode numbers vary by vendor.
