Well its time to chill out the rest of today because folks...get ready for some of the fiercest storms for years with the added bonus that a few Tornados will be seen !!!
You are probably saying Tornados here ..never ...but read on for facts.
The fact was calculated by the late Dr Fujita of Chicago University. He devised the standard method of measuring tornado intensity. Fujita figured that since Britain has an average of 33 tornadoes every year in an area 38 times smaller than the USA, you're twice as likely to witness a tornado here.
How tornadoes happen
Warm and cool airstreams collide
A rotating area of low pressure storm clouds form
Air within a low pressure front rises, creating a strong upward draught like a vacuum cleaner
This draws in surrounding warm air from ground level, causing it to spin faster and faster
These strong air currents can create a vortex - a spiralling funnel of wind - that can reach speeds of 300mph
<LI>Where the funnel touches the ground, it creates a path of concentrated destruction, rarely more than 250m across
Heavy objects, like cars and cows, can be sucked up and flung around like confetti, and houses appear to explode. This is because air pressure within the vortex is extremely low. Inside the building the air pressure is normal, so when the tornado passes over, the air inside the building expands, creating an explosion.

Tornado in Oklahoma Wind speeds in tornadoes can vary from 72 to almost 300mph. Fortunately, only 2 percent of all tornadoes have winds greater than 200 mph.
Seems like Monday was a pre curser of whats to come ..for us in the North Midlands ,North West UK.
Funnel Cloud, Cornwall
**Reality Check Please**
**Uk Tornados are far smaller than the US versions**
Please read this for information on UK severe storm warnings

(should I be more trusting..?) 
I shut down the house mains if there is a violent thunder storm
