Record high temps will be challenged or broken this week

WASHINGTON — The strongly amplified weather pattern dominating North America right now is pumping unusually warm, but dry weather here along the Eastern Seaboard, and a pattern like this is usually slow to break down.

As a result, for a couple of days at least, some record highs will be challenged or broken. All the cold and stormy weather is in the Rockies, the southern Plains and the lower Mississippi River Valley. It’s as if a “Bermuda High” were affecting us like the ones that cause heat waves in the middle of summer.
