Discussion

Today should turn out to be the hottest day of the week with temperatures soaring into the 90’s; however, an end to this hot weather is on its way with the passage of a strong cool frontal system. That front is likely to produce a fresh round of showers and thunderstorms later today and early tonight and some of the storms can be on the strong-to-severe side in the I-95 corridor with damaging wind gusts, heavy downpours and possible hail. Tomorrow will remain quite warm, but much more comfortable than today with noticeably lower humidity values following the frontal passage. 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 couple of days as a large sunspot region produced a G4-class geomagnetic storm on Sunday and northern lights were seen last night as far south as Georgia.
