Convective / Storm Risk Discussion - 21st July 2013 onwards

[Evening thunder]

Some interesting altocumulus cloud formations passing over now, took these recently, maybe a good sign for some?

 

[Lynxus]

Figured Id show yall a sat image I took ( i think in 2006 ) when we had an epic storm.

 

It went on for hours and hours and hours.

 

Lets hope we all see something like this!

[A.J]

Steering winds bring those storms onto the south coast near Southampton....could be an interesting night for Som/Dorset/Wilts/Hants/Surrey & Sussex if the storms cluster regenerate with nocturrnal cooling

[storm1080]

Highly probable I'm up Portsdown Hill above Portsmouth with AdiF in 20 minutes, we'll let you know what we see

[Wilxy]

Theres a cell heading for Weymouth, picking up strikes!

[A.J]

mixed layer lapse rates look very conducive for elevated convection overnight, so nocturnal cooling should play a factor, lots of instability and energy in the mid-levels

[Mumbles]

Thinking about heading to Portland Bill...what do you think our chanceson storms are? Anyone!?

A Lightning show tonight more than anything is the most I am expecting, but they may become surface based when they hit the downs though I take it? Urban heat affect can also spice things up and they may re-explode....

Wow,  what a vantage point

[Andy Pepler]

just spoken to a ham radio friend in weymouth and he is dropping all of his towers and antennas..his strike alert has gone "NUTS"

[Tom Jarvis]

Like the sound of the storms heading my way but would like a eastwood shift in the models in an IMBY sort of view

[Cloud 10]

That takes me back...

 

[ChezWeather]

Looks like a cell is heading for Weymouth... Cant see anything from here in Cadgwith

get ontop of cheny wiers carpark just before the bill..its higher up with better views

[A.J]

ok, a quick snapshot of the ATD Lightning Detector courtesy of NetWeather Extra....

 

Most of the electrical activity is concentrated on the western flank of this multi-cell cluster, and these more discrete storms are drifting due north across the channel.......they seem to be following the T850/T700 Hpa wind flows suggesting that they are elevated in nature.....I'll be watching the radar with interest as things could get rather lively for southern counties later on tonight

 

[MR CB]

Getting excited about the prospects over the next few days - have just seen some Castellanus streaming in tonight while the light fades...hoping that we may see some lightning off the coast by midnight or early hours.

[Paul]

While we wait for the first of the storms to make landfall, thought now would be a good time to post a link up to Nick's superb guide to storms in the British Isles, well worth a read:

[Staffordshire]

What general direction are they heading in? and will this change over land?

[Gord]

Those storms are headng dur north at the moment. Are they due to keep heading that way or will they start getting a more easterly element to their track?

 

Edit: Snap Staffordshire! You must be thinking the same as me with the direction they appear to be heading in! It's no co-incidence we're both from the West Mids and are asking the same question!

 Looks like a tasty MCS...

 

[Wet'n'Dry]

Looking at the visible radar image the French cell appears to be decaying towards the east, however the band of cloud/moisture approaching us from the west is likely to add fuel for an early hours explosion in the west country, and with any luck to spread across the southern counties during the morning.

[Norfolk Sheep]

MCS in France? I should have stayed in Holland, far more chance of seeing something

[Allseasons-Si]

WOW,nice developements to the south at the mo,and starting to cross the channel too,heres hoping that i see some of the action tomorrow evening as i am on the morning shift

 

i am hoping my stormshield will break down from a power cut by a lightning strike nearby lol

 

got my new 1080 hd vid cam ready for it's debut voyage,

 

good look everyone.

[joanna1971]

Staying at poole harbour and seeing my first lightning in years...woop woop, last few minutes constant, no thunder heard yet

[Convective]

This webcam might be of use this evening! http://www.starcross-fcc.com/webcam/

 

Must admit though.. my excitement got the better of me then when I though I had found ball lightning, only to be let down by the realisation that it was infact the moon
