Discussion
An upper-level trough will rotate over the Mid-Atlantic region today and it will be followed close behind by a second system that will keep it very unsettled around here right into Sunday, Mother’s Day. There will be occasional showers today and it will be unseasonably cool with an ocean flow of air keeping temperatures well below-normal for this time of year. It stays on the cool and unsettled side this weekend with temperatures likely confined to the middle 60’s for highs on both days and there will be the threat of showers from later tomorrow into the day on Sunday. High pressure takes over early next week and it’ll warm up on Monday with the return of sunshine.
One final note, there has been a lot of activity on the sun in recent days with a very large sunspot region known officially as AR3664 having unleashed as many as five coronal mass ejections towards Earth. One of the main ejections will arrive into Earth’s upper atmosphere on Saturday, May 11th, and it can spark geomagnetic storms as can a couple to follow close behind later this weekend. Watch for auroras as far south as Virginia during this weekend event which is being classified as a category 4 “severe” geomagnetic storm…rarely seen in recent years.
