Fresh from England's Test series triumph against India, Jos Buttler and Moeen Ali are the box office names in the first match on Finals Day.

Buttler has thus far been restricted to two games in the T20 Blast this summer and has only managed 16 runs, but he is one of the most feared white-ball batsmen in world cricket.

He would love to help Lancashire Lightning repeat their 2015 triumph at Edgbaston - but Moeen has something he doesn't, a T20 century to his credit, a brilliant 115 off 56 balls against Birmingham Bears last month.

A repeat of that in the first semi-final, and it could well be the Rapids, not the Red Rose county, that take the next step towards getting their hands on the silverware.

So how's the weather looking for Finals Day?

Here's Midlands Today's Rebecca Wood with the local forecast.

Provided there's no interruptions through rain or bad light, here's how the big day at Edgbaston is set to unfold:

11:00 BST: Worcestershire Rapids v Lancashire Lightning (first semi-final)

14:30 BST: Sussex Sharks v Somerset (second semi-final)

18:45 BST: 2018 T20 Blast Final

It's the best day in the British domestic cricketing calendar.

Three matches, 120 overs and 11 hours are all that's left before the 2018 T20 Blast champions are crowned at Edgbaston.
