WILMINGTON, Del. – Delaware skies may deliver a rare September spectacle tonight as the Northern Lights push far beyond their usual range. With mostly clear conditions expected through Tuesday morning, Wilmington residents could glimpse the aurora before midweek rain arrives.
According to the National Weather Service, calm winds and overnight lows near 58 degrees will keep visibility strong across New Castle County. NOAA’s Space Weather Prediction Center warns that a coronal mass ejection racing toward Earth could spark geomagnetic storm activity through Tuesday, making aurora sightings possible as far south as Delaware and Kentucky.
Drivers along I-95 near Wilmington should stay alert tonight. Increased nighttime traffic from aurora watchers may create unexpected slowdowns. Residents planning to view the skies are urged to avoid rural roadside stops and instead use safe, open locations away from streetlights.
Tuesday will stay sunny with highs near 80 and light afternoon winds. Wednesday looks mostly sunny as well, though clouds will increase late in the evening. By Thursday night, showers are likely across northern Delaware, with a 60 percent chance of rain that could linger into Friday morning.
Meteorological fall has started with mild days and cool nights, but unsettled weather late week may bring travel disruptions. More advisories could follow as Thursday’s storm system develops.
