New cycling specific rain forecast for Manchester

Cycling in Manchester and the north west in general makes you very aware that we have weather in the UK.  I admit, I do obsess about the weather and have various forecast sites bookmarked on my computer.
One of my favourite, and most accurate in my experience, is metcheck.
Its dead easy to use if you a. know where you are and, b. can type.
They have just added a function which allows you to select your activity and it provides a tailored forecast detailing those elements of the forecast which are pertinent to said activity.
So, for cycling you get wind speed, a meaningless UV index and something called the SweatIndex.

How much is it going to rain this weekend?

Although the Sweat-dex doesn't appear to be operational yet, the wind and rain volume counts are useful. It's easy to understand and you can tell, at a glance, how wet you are going to get, how intense the rain will be and at which angle the rain will be battering you from.
Good stuff I reckon.
