So 10 days ago, the Canadian or GDPS progged some very insane cols temperatures for Jan 6th, 2018 back in late December. So how will it all verify?

Nice bust for sure. But also to be slightly fair, I think that was a run when cmc had a wide swath of snow on the ground? I don't remember
Ah ok. Oh for the record, I don't think winter is done yetIt actually was with some snow cover but mostly east. I believe this was when the GDPS had a 1056mb high around this tine but it dropped south on progs but ended up moving more east.

The observed low at KFLO was 8 early this morning.Yeah, the CMC cold bias is for real and significant. Just today's 0Z run had a low progged for Myrtle Beach of 10. The actual low was near 15 (still amazingly cold, of course, but that's irrelevant).
The CMC cold bias appears to be worst with overdone radiational cooling. OTOH, I don't think the cold bias includes wedging situations.
The CMC prog for Florence's low tonight is high single digits. Compare this to the NWS fcast of near 21. Let's see how the CMC does with this.
Aside: It is a rarity to see 1040 mb SLP in SC but that happened late AM today!
