Storm Stage: Mature (multiple cells)
Path / Movement: Overhead / Northwards
T0002 consisted of several large active cells
pulsating northwards along a thundery cold front. They occurred at
night-time making them more spectacular and had a total duration of about 3
hours. I audio-taped
the thunder and captured a few good ones including a couple of loud crashing thunders. The storms cleared the
area at about midnight. Obviously I only audio-taped the peak of the activity
when it got close, however after three hours of watching I then got bored of
the distant discharges and went to bed. It was an excellent storm though
which would have been a good one to film.

Looking at the Dundee satellite quick-looks the storms generated were a
result of warm moist air being dragged up from the continent being lifted by
an approaching secondary cold front wave from the west. Looking at the
02:15 IR image it is clear that there were large amounts of
convective activity running in a line up the country, and possibly also in
the North Sea. The
difference in the IR signal can be seen behind and ahead of the front
showing a strong temperature gradient. By this time a new "cut-off low"
appears to have formed in the Bay of Biscay along the waving cold-front.
This waving line of slow-moving but intense convection is the likely cause
of such a succession of storms in the north-west region on this night.
