500mb Geopotential Height & Normalized Anomaly really is a great geeky weather visualization of "where is the extreme weather"

(Red = much warmer than normal, blue = much colder than normal = heat dome in California, and very cold weather centered over Ilinois in this Monday forecast, I believe).

Oooh, look at the forecast for Fryday... err.. Friday. Good luck Arizona and Nevada. Death Valley, too.

My parents wintering in Arizona aren't quite ready to migrate back to the PNW for the summer. Mom was under the impression it'll just be a blip ("technically it's still winter!") 😂

Anyhow, I put a bug in their ear about the heat a few days ago, so hopefully they're ready for it and the normal weather forecasts have more of an impact when finally arriving.

geeky interjection:
Depending on the exact locales involved, it looks like some careful route planning could have your folks riding an isobar all the way from AZ to the Pacific Northwest.

*assuming they completed all their travel before Monday's 18z prediction changes, which seems unlikely in both meteorological & human-behavioral terms
