Will the new NOAA data result in any classification changes for U.S. cities?

I also wonder if changes will be made to the USDA hardiness zones?

Now Washington DC sits at 15.2ºC for the annual mean. So, firmly into Subtropical in my system.

Also

Tampa

1981-2010: 46.3in
1991-2020: 49.5in

So, all the permanent talks about Fl 'dryness' here, doesn't have substance.

True, however, that rain largely comes from 5 months of the year aided by hurricanes. The Dec-May period can be extremely dry.

Everyone except the upper Midwest may have ever so slightly warmer hardiness zones especially where one borders on another zone, I feel both DFW and Indy may be a bit more solidly zones 8a and 6a respectively.

I'm pretty sure that -2°F Low DFW had back in February was enough to drag them to lower 8a

Augusta, Ga's hardiness zone is now 8b, coastal Georgia is probably more towards 9a/9b.

There's a large canary island date palm near where I live and it seems to never get burnt during winters, it's fronds are always a deep dark green, maybe more evidence for our 8b-ness.

You’re probably right, and it’s only a matter of time until Indianapolis has record cold low temperatures again(by central Indiana standards), Indy just lucked out this past winter.
