Fresh air filters in

What a difference a day makes.

The drier air will last through Friday, before a warm front gurgles back north and brings a renewed surge of 90 degree heat and sticky humidity this weekend.

As the front bubbles north Saturday, it’s likely a few thunderstorms will follow. One or two has the potential be severe later Saturday night into Sunday, according to SPC.

Aurora strikes again:

Reports indicate the northern lights flashed again last night in northern Europe. Apparently the sky was lit brightly enough to show the aurora over the city lights of Stockholm, Sweden. Amazing images were also captured over Norway.
