Weekend Review: Pope Francis was greeted with fall-like conditions as the Northeast and Mid-Atlantic trended cooler than normal, spurring demand for warm beverages and cold weather apparel. Cooler than normal conditions were also felt across the Pacific Northwest. Above average warmth continued in the Plains and Inter-Mountain West, keeping demand soft for fall consumables, while the Southeast saw a continuation of heavy rain and severe storms.

Ain’t No Fall Here. While autumn officially began on Wednesday, September 23rd, warm temperatures continued to dominate as the U.S. had its warmest 4th week of September since 2010. The Mountain region trended warmest in 55+ years. The West North Central region was warmest since 2005, Pacific region since 2009, West South Central & East South Central since 2010.

A Glimpse of Fall in New England.
