It probably is over in Hertfordshire?

After a warm sunny morning, arrived at the Northaw assembly area this afternoon to be greeted with a 30 minute bank of cloud, to right and left blue sky but not where I was watching! At 2.40 I had 30 minutes of 100% sunshine followed by a further 20 minutes of sunny moments.............the only activity in the assembly area was by two imposters - Red Admirals that flew up high clashing! Otherwise sadly nothing - Liz
