LOL. Better chance for 'Nutballs': bowling ball like lows along the lines of what Nut said. Less likely for severe warm ups but it's a 240 hour map so.
If one looks at the final 500 anomaly panel for the 12Z EC, its like night and day vs. 0Z. From Sig ridging over to more zonal. This is indeed something more appropriate for the Ensembles though.
It gets there a different way from 0Z, with more of a transient trough this run, but the surface reflection in the Gulf is similar and not that impressive. Not going to get anywhere near us with that HP in NC.
I had someone out there, a bit west of the Palouse but still in the path somewhat, who sent me their Digital temp reading of 115. And they use a heat pump for A/C so it was a bit uncomfortable for them.
Some are interested in any weather phenomena that is well off the norm. Otherwise, the Palouse never gets mentioned here. According to Wiki, the highest temp ever in a Minn December is 74. @MrFreeze6298, you may be interested! @Itstrainingtime
That was what I saw over some various Op runs the last few days. Snow chances but no sustained cold as the cold faucet never opens from the north. We have been dealing with the zonal's every winter for some time now There was the one run where it put a deep trough in the west but otherwise has been more zonal than anything.
