Narrative:

ZZZ1 got hit with thunderstorms and we had numerous flights holding for ZZZ1 in particular I had 4 flights holding. Alternates for these flights were ZZZ2/ZZZ3 ZZZ2/ZZZ4 or ZZZ2/ZZZ5 after flights were in hold and due to fact ZZZ2/ZZZ6 were thunderstorms free we looked at shortening up to ZZZ2. Then captain on one of the flights called me and advised ATC told him that ZZZ2 was closed and we couldn't go there either. I was looking at flights land ZZZ2 the entire time. This it the 2nd time ATC has refused to allow my flights to divert to an airport with perfectly good weather. About a month ago I had 2 flights holding ZZZ7 area...shortened up to ZZZ6 because weather was good there only to have ATC refuse to accept the flights to ZZZ6. I had to scramble and change alternates again to ZZZ8/ZZZ5 and we ended up landing there with thunderstorms around the airports with what I consider minimum fuel good weather. I came real close to having to declare a minimum fuel emergency that night. This situation is completely unacceptable and could result in having flights land with critical fuel into stations with less than optimum weather conditions. The only solution I see is to have captain or myself declare and emergency and go to the alternate we need within fuel range of aircraft. We ended up having to divert flights to ZZZ4/ZZZ9 due to ATC's refusal to allow us near ZZZ6 or ZZZ2.
