NOAA/NCEI Climate at a Glance, contiguous United States. This is the observed record for the month, not a score of anything said in this piece — the forecast ledger begins 2026-08-17 and cannot reach earlier posts.
Too much going on over the next 10-days to fit into one post. So, updating on the intensity and progress of the forecast Arctic blast mainly peaking on Monday and Tuesday of next week across the central U.S. including Texas, and then into the Great Lakes and Ohio Valley. I’m also constantly updating on X/Twitter (@RyanMaue).
The conventional weather models including GFS initially weakened the extreme cold of the air mass with a cut-off low from the Pacific undercutting the polar front. However, that has largely faded. And, to top it off, the A.I. trained models are more extreme. I’m not entirely sure if these models have a cold bias, but both FourCastNet (Nvidia) and GraphCast (Google) are impressive!
