FL will just be a very dry and humid place in another 30 to 100 years with more freak heavy rain events and months of dry weather. Huge change already in the last 40 years since i started keeping records. The 7 years have been off the charts.
Similar in the NW...the past seven or so years have been quite a shock and our climate has seen quite the degradation over the past decades as well in terms of winter.
Our regions seem to be warming the most; conversely, the NE has seen extreme cold and gotten five or six straight above average snowfall seasons. Really weird and persistent pattern.

Overall, we are getting wetter in spring/fall and drier in summer.
I'm not so sure that our region is warming the most. The last few summers have definitely been warm by Seattle standards, though.
Yeah if you plot the H5 maps for the current 30 year period (1989-2018), it mostly matches up with your observations, and the patterns we've generally experienced in recent years.
For winter, the east is indeed cooling and the west warming. this is especially apparent in the last 15 years, with a trough centred in the western Great Lakes and a monster ridge out west.
It's more of a north-south difference, as opposed to east/west, in early spring. The south is warming while the north is cooling.
May is warming for everyone but especially for the NE and the west coast.
Summers are getting hotter in the west and the far east (Atlantic Canada) while it is neither warming or cooling everywhere else. And contrary to climate models, the Arctic is absolutely torching during the summer.
September is the month that has warmed the most for the NE. The SW has also warmed but not as much. Meanwhile, it's the only month that has cooled for the NW.
Fall is interesting. In the current 30 year period, the mean is ridge west/trough east but if you take the last 15 years, the ridge shifted eastward to the plains, with a trough ridge trough configuration.
This is the H5 map for this past summer. It featured higher than normal heights (almost) circling the mid-latitudes with lower than normal heights in the north. It's a close match to what some climate models are predicting. Perhaps a preview of what's to come?

And if you made the same plot for the past few winters, the giant trough plunging out of Hudson Bay would be present; at the same time, the west would be pasted under red. Scary how scarce cold is becoming in the winter over here....we normally average 2 days below -10C...haven't seen that since 2013 now.

Any source for this?
Seattle has an annual mean minimum of -6.9 C as stated on Wikipedia. Vancouver's average winter low temperatures are only 1.1-1.3 C colder. Vancouver even has the same all-time record low as Seattle.

...Actual number is 1.6 days per year at the airport. Further inland in Abbotsford it's 2.2. Vancouver also averages 3.4 days below freezing per year, while it increases to 5.8 days at Abbotsford.
Regarding the all time low..recall the station for vancouver is situated right next to the ocean. A few km inland where most of the population lives, record lows are generally about 2-5C lower.

Okay, but I suspect some years have many lows below -10 C while most years have none, bringing the average to 1.6. Recent winters may have gotten more stable with less intense cold spells, but Seattle's data shows that average winter temperatures haven't warmed up by much. The record for the last decade isn't that different from the 1981-2010 normals for winter:
December: 40.8 F 2009-2017 vs. 40.4 F 1981-2010
January: 42.2 F 2009-2018 vs. 41.8 F 1981-2010
February: 43.6 F 2009-2018 vs. 43.2 F 1981-2010
Most of the warming is happening in the summer here. This is an exception to the general rule that winters warm up more than summers as climate change progresses.
