Discussion

A long-lasting geomagnetic storm did occur over the weekend as a result of the coronal mass ejection (CME) from Thursday’s X-class solar flare. At first the CME’s impact seemed relatively weak, but then conditions in the wake of the CME became somewhat stormy with satellites in geosynchronous orbits exposed to solar wind plasma according to NASA Goddard scientists. Also, northern lights were visible over the weekend (where the skies were clear) as far south as Arkansas, Missouri, Kansas and Nebraska and across most northern US states from Maine to Washington.

High pressure off of the east coast will dominate the weather scene into mid-week. From this position, the high will pump in hot and humid air with temperatures likely to peak on Tuesday and Wednesday well up in the 90’s throughout much of the Mid-Atlantic. A cold front will pass through by Thursday and bring relief for the late week with cooler and less humid air moving in.
