Also, models have trended toward a stronger CCKW over time. Notice how earlier GEFS run weakened the -VP signal assoc. w/ the CCKW across the e. Atl. The new run keeps the -VP signal more intact and slows down the CCKW there, potentially prolonging its influence on the trop wave pic.twitter.com/v7ZM89I1XY
