Temperatures have soared above 80° for the past three days and tomorrow will make four.  Sunny skies, light winds and dry air have made these temperatures feel very comfortable.  It appears that changes are on the way by Friday and the weekend.  A strong cold front will reach western North Carolina by late Thursday and will push off the coast early Friday morning.  Winds will shift to the north and cooler temperatures will follow.  Highs will only reach into the 60s this weekend although skies should begin to clear by Saturday afternoon.  Overnight lows will put the real taste of fall in the air as inland locations will plummet into the lower to middle 40s by early Sunday.  It appears the fall-like weather will stick around for a while and it is unlikely that we'll see middle 80s again until next spring.  Get out the jackets and sweaters.
