Its a big storm and its heading your way!

Just clipped past Malvern. Seemed to be mostly over in Herefordshire, but
what I could hear was continuous thunder (no breaks in the sound). We got
a few heavy rumbles here with some rain, but nothing like what it looked
like they were getting furter west.

Surprised nobody from that direction has made any comment yet. It looked
extremely intense.

Very dark overhead with one or two flashes of lightning. Very muggy
and temperatures around 19C for the past hour.

Could go either way at the moment, either a massive storm or either
fizzle out. Pleased to see my station forcasting software picked up
the storm though 2 days ago.

It appears that this whole area of storms was 'born' over the Malvern Hills
& North Cotswolds before around 09:00 hrs. As I left home in Malvern to
drive to work in Swindon this morning between 06:30 and 07:30, there were
short outbreaks of moderate rain from medium level cloud but it appeared
then along with the 06:30 Hereford & Worcester local weather forecast that
it would be an improving situation during the morning.

However, between 06:45 and 07:00 driving down the M5 towards Gloucester, I
noticed through the then broken cloud, extensive areas of AC Cast to the
West towards the Malvern Hills and as I went over Birdlip just after 07:00
hrs, it was becoming very gloomy but no current rain.

By 09:30 hrs or so, I had a text from my partner in Malvern as she just got
back from walking her dog saying that a severe T/storm had broken out in
situ over Malvern with no warning other than some heavy rain before hand.
Remotely monitoring my own weather station via Wunderground showed the Solar
radiation level had dropped to very low levels at this time and increasing
rain intensity. Analysis of local lightning data from an adjacent Malvern
Wells weather station who uses a Boltek showed a massive area of active
T/Storms from the Hereford/Worcester to Cotswolds area which over time moved
onwards and expanded to the north.

The rest as they say............

There was nothing in Swindon, just a hot, humid day with a fairly strong S
wind.

My own records showed only 8 mm of rain but with a peak intensity of 60
mm/hr at 10:00 hrs. Further to the North towards N E Worcester, other PWS's
were showing up to 15 mm rain.

The first time I've observed 'combined activity' over the Cotswolds and
Malverns merging and leading to an area of rapidly expanding severe weather
in Summer since the late July ending of the June/July heatwave in 2006.
