Discussion
Arctic air continues to impact the eastern states here at mid-week and today will feature colder-than-normal temperatures around here along with a continued stiff westerly wind making it feel even colder than the actual air temperature. A cold front passes through the area overnight and it’ll usher in a chilly air mass for the remainder of the week with temperatures remaining below-normal Thursday, Friday, and Saturday.
In terms of space weather, a very active sunspot region unleashed three separate solar flares on Sunday, Monday, and Tuesday and each one resulted in a coronal mass ejection (CME) headed towards Earth (full story). The combination of the first two CMEs impacted the Earth last night with auroras seen around here in the Mid-Atlantic region and in unusually far south locations such as Texas, Alabama, and New Mexico. The third CME that was unleashed early Tuesday morning - the strongest solar flare of the year - could result in more northern lights on Wednesday night so be on the lookout for that if skies cooperate (and they should).
