Unusual Short Range Tropo

As noticed by a fellow band 2 DXer in Kent, there have been some very strong signals from the nearby continent over the last few days. It must be down to tropospheric enhancement though I was wondering if it had anything to do with my recent aerial upgrades and improvements, both at home and in the car, where I have built a semi-permanent quarter wave/magnet mount. The effect seems to have been observed only along the east coast.

Jet stream position: 06-06-13

Some of this will probably be down to the movement of the jet stream which has moved a long way to the north of the UK for the last few days, allowing warmer air to come up from the south. Temperatures have only been mid-teens however. The "British Summer", as some love to call it, can throw up many surprises. Temperatures could be in the 30s C soon and then snowing a week later ;O) Totally unpredictable!
