The match between Essex and Gloucestershire was abandoned without a ball being bowled, handing Somerset first place in the group some time before their game against Hampshire was completed.
That left Essex hoping for good news to come from elsewhere and it did - for them, Kent and Surrey as the evening progressed.
Somerset put the seal on their dominance of the South Group with a five-run win over Hampshire as they held their nerve when the game went down to the wire.
Batting first, Jim Allenby (69) and Mahela Jayawardene (55) struck a 108-run partnership for the first wicket to help Somerset eventually post 250 for nine.
Hampshire fought back thanks to Ryan McLaren, Brad Wheal, Liam Dawson and Mason Crane all taking a brace of wickets but it wouldn't quite be enough.
Jimmy Adams (50) and Will Smith (59) both struck half-centuries to keep Hampshire in the hunt but just as Somerset had, they lost wickets and from needing 104 from the final 15 overs, needed 83 in 10 and then 48 in five as Somerset tightened their grip.
Lewis Gregory and Tim Groenewald were excellent at the death and it was Groenewald, defending a lead of 13 going into the final over, who capped the win by having Wheal caught and bowled for 13 to dismiss Hampshire for 245 and send them out of the competition.
Rain throughout the day meant a series of inspections and prospective start times were pushed back until play in an 18 overs per side match did finally get underway in the early evening in what became - thanks to Hampshire's defeat - a winner-takes-all clash.
Middlesex made their way to 86 for six in the 13th over when the rain returned, causing a small delay. When play resumed, the match was reduced to 16 overs per side and Middlesex closed on 101 for eight, Tom Curran taking three for 16 and Stuart Meaker two for 15.
Surrey made a terrible start to their run chase, losing Jason Roy (0) to the first ball of the innings and then slipped to 28 for three when Steven Davies (1) and Rory Burns (5) also fell cheaply. Aaron Finch cracked a quickfire 24 in 16 balls but his dismissal left the game in the balance again.
Middlesex were able to slow the scoring but once Ben Foakes and Zafar Ansari got thesmelvesthemselves in they were able to provide the acceleration required, the former hitting an excellent 45 and the latter 29 not out to put Surrey into the quarter-finals, even though Foakes fell with the scores level.
Half-centuries from captain Sam Northeast (66 not out) and wicket-keeper Sam Billings (55) eased Kent to a seven-wicket win over Sussex and guaranteed their place in the quarter-finals for the third season in a row.
Sussex handed one-day debuts to Abi Sakande and Christian Davis - both would take a wicket later in the day - before limping to 182 for eight in the 43 overs each side were allowed due to rain.
Rocked by a Matt Coles (4-39) triple strike early on, they needed Harry Finch's 54 and Fynn Hudson-Prentice's 48 to guide them to some sort of score, but it proved well short.
Kent lost openers Joe Denly for 24 and Daniel Bell-Drummond for 14 before Northeast and Billings put on 103 together for the third wicket to take Kent to the cusp of a win that was eventually sealed with some 12.1 overs in hand and move them to second in the table while they waited for other results to come in.
Shame about the batting and the result, spicey bowling from the Kent boys! But great to make my @SussexCCC debut...— Christian Davis (@daviscal123) August 2, 2016
No play was possible in Bristol, where Essex and Gloucestershire shared the points. Essex then faced a nervous wait before their place in the quarter-finals was eventually confirmed by Hampshire failing to overcome Somerset.
