Visualizing weather patterns for last 85 years (Seattle)

I have been looking into long-term weather patterns, and put together the attached charts. I haven’t worked with weather data before, so this is new to me. Appreciate any tips or suggestions to improve.

One thing I am realizing is that weather patterns are changing in different ways for different points on the globe.

Interesting take-aways for me:
– we do see a warming trend in the data over time
– we see decreased snowfall over time
– the decrease in wind speed over time (observed elsewhere too)
– no significant long-term trend in rainfall (though some decrease)

Data used: ERA5 monthly averaged data on single levels (2m temperature) from 1940 to present (the data window available from ERA5). I pulled the data by a “gridded pattern”, the resolution of which is dozens of square miles. The coordinates were for Seattle.
