THUNDERSTORM T0102 Date: Tuesday 19th into 20th May 2015 Time:
~23:55 Local onwards Location:
Norman, Oklahoma. USA. Path: Overhead
Synoptics: "Weakening" rearward
sloping cold front Duration: about 1 and half hours Type: Rearward sloping Multicell Squall Line Average lightning type: CG/GC and Anvil Crawlers Footage Quality: Full HD / DSLR
A "weakening" linear
multicell storm (weakening as in becoming less tower and more anvil)
followed behind a plume of more intense thunderstorms
and embedded supercells during the day (see
T0101 with close CG strike). This
passed through Norman, Oklahoma, just after midnight to finish the day off.
Rearward-sloping and elevated linear characteristics provided perfect conditions and
viewing for large cloud-to-cloud lightning discharges. Here we have some
regular negative C-Gs at the beginning (along surface cold front where the
cumulonimbus towers were) followed
by a rearward sloping Anvil across the entire horizon, with some of the best Anvil-Crawlers I've seen to date,
including some Positive flashes and Ground-to-Cloud crawlers.
Had a fantastic view from the hotel window, albeit shooting through
triple-glazed rain-drenched windows (again, like with
T0099). The clicking noise you hear in the
video is the DSLR
shooting autonomously with the Lightning Bug (Tm) trigger. Despite shooting
through a window, the resulting DSLR shots were much better than expected
with the exception of a bit of mirrored
ghosting of a few strikes.
The next shot is by
far my best Anvil Crawler capture to date. One take, no stacking (in any of
these). Just look at how many branches there are!
Then a few CGs and
GCs to finish the show off
Here is the radio
mast (again, as with
T0099) that released the last bolt of lightning
