Some extreme rain here just ending. Not much in the way of thunder...a few cracks but impressive rain fall totals. The cell seemed to pep up slightly east to my location. I'm wondering if anyone in Uttoexeter had some good thunder under the cell?

Blimey a weak Thundery shower slipped past the shield. No doubt a firmware update will be applied as I type

TORRO TORNADO WATCH 2014/003 
 
A TORNADO WATCH has been issued at 1045GMT on Monday 9th June 2014 
 
Valid from/until: 1045GMT - 2100GMT on Monday 9th June 2014, for the following regions of the United Kingdom & Eire: 
 
Parts of (see map) 
 
NE England 
 
Lincs 
 
Midlands 
 
E Anglia 
 
THREATS 
 
Tornadoes; hail to 30-40mm diameter; wind gusts to 60mph; CG lightning 
 
SYNOPSIS 
 
Shortwave trough moving NNE across the area has promoted elevated thunderstorms this morning across W Midland, ref. TCD002 below. Surface observations of temperature and dewpoint close to the cluster, especially the SE side of it (currently over N Midlands) suggest that surface-based activity is possible. Backed low-level flow ahead of this cluster suggests low-level rotation is possible, and low LCLs suggest a risk of tornadoes. Deep layer shear is sufficient for cell organisation and possible supercells, with the risk of large hail/damaging winds. The highest risk is with this cluster, from ~Derbyshire NNE through W and S Yorks to N Yorks, over the next few hours. Other storms, perhaps severe, may form to the SE of this cluster, also with the risk of large hail/tornadoes, although the risk lowers with SE'wards extent, due to 1) veering low-level flow as frontal system moves NE, and 2) cirrus shield from multiple MCSs over the near

No lightening seen though

On a train between Derby and Chesterfield.That cell showing is a hail producer.Quite large pellets in with monsoon rain as the train whistled through.
