Just for warmth thoughts … sun angle rises as much from Feb 5 to Feb 28 in 23 days as it did in the 46 days from Dec 21 to Feb 5. That’ll add a a little zip to your step.
Thought the trough initially was a little farther west, the ns is diving in a little sooner, spacing from north to south is a little closer and the trough was a little less broad with slightly higher heights in front.
