Can't see evidence of a sting jet in satellite imagery , wonder if the
gusts are due to convective downdrafts (sferics in area) or orographic
effects from the Pyrenees,

There was a more pronounced cloud hook on the earlier imagery and the
topography will have come in to play with some of the gusts. But for the
most part the sting jet was considered responsible.

Ah the 24hr airmass loop is more convincing,was that NMC diagnosing the

There was a pressure rise of 12 mb in an hour at Bordeaux
(LFBD) between 6 & 7 GMT today.

Well spotted ... as I'm here, or "there" for you (well, somewhat
further
north in the Haute Vienne) I can confirm much medium level
electrical
activity on Mon evening, a dramatic cold frontal passage this
morning
just before 10am CET with ugly clouds,
sudden rain squalls, a sharp wind veer and rapid increase, and a
sudden
temperature drop from 18 ot 11C. The strongest winds (I'd estimate
gusting
50-60kn) were immediately behind the cold front, i.e. between 10am
and
midday. Many trees and branches brought down, in turn bringing
down
power lines. We were without power here from 11am to 10pm ...
great
fun.

According to AFP, 90,000 homes in the Aquitaine region (plus
smaller numbers Poitou-Charentes, Limousin and Midi-
Pyrénées) were without electricity for much of Tuesday, and
some were not expected to be re-connected until Thursday
morning.

hallo from the Dordogne - just celebrating being re-attached to the
outside world after the telephone lines went down - last night we were
one amongst 50,000, apparently. We were lucky with the power, and
remained more or less powered throughout, but many suffered. Much worse
has been going on in the east of France, with flash floods drowning
villages in the Vosges.
