Discussion

A strong cool front passed through the Mid-Atlantic region late yesterday associated with a fresh round of showers and thunderstorms. Although today will remain quite warm, it’ll feel much more comfortable with noticeably lower humidity values. Temperatures will continue to trend downward later in the week and a complex low pressure system setting up near the east coast by the weekend could bring us a spell of cool, wet weather from Friday through the upcoming weekend.

Looking even farther ahead, this late week change to a cooler weather pattern in the Northeast US will stick around as we progress through the first part of July. While we turn cooler in the Northeast and Midwest, the Pacific Northwest will become hot and dry under the domain of a strong upper-level ridge of high pressure. Finally, the sun has had an active few days as a large sunspot region produced a G4-class geomagnetic storm on Sunday and northern lights may be visible again tonight from a second wave of plasma expected to arrive this evening.
