Worth noting that the (daily) record breaking heat in the northern Sacramento Valley today (including some 115F readings) is potentially quite a bit lower than if the historically unprecedented ridge, currently centered over BC/WA, had set up shop slightly to the south. #CAwxhttps://twitter.com/NWSSacramento/status/1408945992272019456 …
What's the physical limit on high temperatures in places like the northern Central Valley? I seem to remember that with Death Valley records, the lower atmosphere mixes so completely that you don't get local "hot spots" except based on topography, but I'm sure I'm mangling it.
