Gloucestershire Weather

From about 4am today (20th Jan 2010) heavy rain began to fall in air temperatures of about 4c.

Then the temperature slowly started to fall. But after 6am the temperature started falling quicker and by 7am this rain had turned to heavy snow.

A graph from my weather station showing the temperature drop, look from 4am to 8am.

The purple line is the temperature, the red line is the dewpoint and the green line is the wind chill.

I was amazed at how quickly the snow settled considering the 3hrs previous rainfall.

It left about 2cm on the ground before it stopped and then began melting quickly in temperatures that rose to 2.7c at 4pm.
