THUNDERSTORM T0101 Date: Tuesday 19th May 2015 Time:
~1730 Local Location:
Norman, Oklahoma. USA. Path: Overhead
Synoptics:
Frontal cold front with embedded supercells Duration: about 1 hour Type: An approaching, possibly embedded supercell (showed rotation in
radar) Average lightning type: CG/PF Footage Quality: Full HD / DSLR
An embedded supercell
obscured by an under-cut of low cloud was dropping a barrage of CG northeast
of a weak rotating core (textbook phenomenon). Long duration shotgun
thunders suggest mostly positive (anvil) lightning which is commonly seen to
the E or NE of supercell cores, but possibly also high-based negative.
Hoping for a CG on camera, we got more than we bargained for when a post
down the end of the road got struck (on camera). This was to date the
closest CG strike I have caught on camera, aside from the ones off-camera in
T0036. We felt quite exposed since we
were parked under power lines and the big Newcastle water tower, so we
legged it! The proceeding hour saw continuous torrential rain and much
lightning across Norman with plenty of flooding. We were on-route to a
restaurant so didn't get much footage thereafter.
