Thunderstorms

Postby greg_gruner » 2013 Oct 20, 15:04

Thunder was heard in Farnborough at 1350 BST today (just one rumble) in the midst of a series of heavy and prolonged showers that produced 10mm of rain in around 1.5 hours duration.
My son, who lives at Bramley north of Basingstoke, reported more extensive thunder and lightning there this afternoon.

Quite a few rumbles of thunder here between 12:00 and 13:00 with several brief but very heavy downpours. It turned windy for a time too before drying up this afternoon with sunshine.

I even managed to get the lawn cut. The grass seems to be growing quicker now than at any time this year so far. It's probably making up for the fact that it hardly grew at all over the summer due to the very dry conditions. Everything is so lush and green. Still awaiting any autumnal colour.

Min = 13.8°C
Max = 15.9°C
Rain = 6.0 mm
Sun = 1.7 hours.

(19:42), 14.7°C, RH 90%, DP 13.0°C, 1005 hPa (R), Wind 14 mph SSW.

Thunder in Penzance at 00:30, virtually no rain at that time. Several flashes 3 or 4 miles away around 02:00. Intense shower around 08:45 gave approx 5mm in 5 minutes, small hail and a single flash virtually overhead.

Some rough sea conditions in Mount''s Bay overnight meant the Isles of Scilly ferry (Scillonian III) was brought into the harbour from it's normal position on the lighthouse pier, and there was plenty of seaweed on the prom this morning.

Heavy thunderstorm here in south central Berkshire this evening. Many brilliant flashes of lightning, with some of the best cloud to ground I've seen for years! Started at 1910z - at least that was the first thunder I heard - and still flashing away brilliantly to the east 35 minutes later. A short spell of torrential rain, only 3 mm in the hour though.

And this after a record late October air minimum this morning, at 14.9 °C. And not even a suggestion of an air frost to come in the next few days at least!

... probably allied to your observation - from radarnet & sferics display a well-marked trough line with activity extending NNE along its length as well as the whole thing moving bodily eastward. First activity here was lightning visible well to the south (over the Channel) 1635Z, then first thunder heard 1655Z, after which thunder / CC / CG activity continued until 1730Z. At one point, discharges were coming along /at least/ 6 per minute - possibly multiple cells in the vicinity. One particular CG discharge at 1712Z was near-instantaneous flash-bang, with classic 'crack' so I suspect it was very nearby - certainly less than 300 m: I'll perambulate on the bike later to see if I can find the effect.

Rainfall from the /rainfall/ phase (longer than the thunder-heard phase, but distant sheet lightning visible for some time) was 10 mm, over the period 1701 - 1900Z, with most of that falling within two marked phases: 1701-1725Z & 1755 - 1830Z.

" A BUNGALOW was hit by lightning in West Moors - as firefighters were called to extinguish a blaze. Officers from Ferndown, Redhill and Verwood were called to Oakhurst Road at around 6pm yesterday after the roof of the building had caught fire after the lightning strike. Crews removed tiles to access the roof space before extinguishing the blaze using two sets of breathing apparatus and one hose reel jet. "

Oakhurst Road is between 200 and 500 m away from us, depending upon where exactly along the road it was - will look later.
