Did I miss why Peachtree City is issuing warnings for Birmingham?

IIRC, several NWS offices are doing a bunch of upgrades/updates/etc., and several other offices have had to take over their CWAs until those upgrades are finished and everything's running properly.
 
Gotcha, I knew about the computer systems upgrade, but I assumed that would only effect the weather radios

Strong rotation on this storm, which is unfortunately in a radar hole, NW of Pikeville, TN. FFC just issued its first TOR of the day.

They're in the bullseye of favorable parameters.

If tradition holds, FFC will slap a TOR warning on every bird fart, or at least a SVR with TOR possible tag.

Glad they trimmed the Tor and wind probabilities back a bit. Agree on hatched area for tornadoes. Carefully monitoring the mini cells popping up below the N AL boundary.

This is from an article on AlabamaWX.com about the software upgrades:
During this time, NWS Birmingham will maintain operations by remotely accessing a neighboring office’s AWIPS system, with forecasts and warnings issued by the Birmingham team. If needed, full service backup will be provided by NWS Peachtree City (Atlanta) or NWS Huntsville. Radar data from KBMX and KMXX will remain available, routed through other NWS offices, and weather balloon observations will be processed using an alternate method.

So, in simple terms, it sounds like NWS Birmingham is still writing/issuing the warnings, but they have to be issued through NWS Peachtree City’s system.

We’ve got other action going on besides N AL. Rocky Top (Knoxville) has a lot of action moving towards the city. Couple of TORs but not seeing any reports of any tornadoes OTG.

Should mention that the cells are somewhat training along the same paths like the N AL cells were. Concerning to say the least, but they are in a bit more area of traffic - almost as if they may congeal soon.
 
I think I'm all tired out from this past week, as I'm feeling like my eyelids are heavy (of course, it could also be the pollen in the air as well). Regardless, in any case I'm going to call it a night tonight. In the meantime, I hope things calm down tonight, so that everyone can get a good night's sleep tonight! :)
