What's going on here then!

Temp current time (8.15BST) here in Newbury has risen a good 1C over the
last hour, now so what's causing this? I would imagine I should be
expecting a bit quick drop once the rain clears to the south/east (well, if
it ever does tonight!!! judging by MO radar) Currently a little rain and
gusty wind and pressure dropping quite impressively. The local town website
http://www.thatcham-weather.info/ is showing the trend well.

What next?
