Narrative:

Heavy to extreme precipitation approaching mco from the west; the first B737 was on final for runway 35R with a second 7-8 miles in trail. Prearranged coordination with the tower was in the event of a missed approach they would be issued 2;000; eastbound. The first B737 went around due to being to fast; he first made contact I said 'climb and maintain 3;000; say your intentions?' he stated he was low on fuel and wanted to try again but if he did he needed to go right back around. I knew his company was behind him so I climbed the first B737 to 3;000 to protect for the second B737 in case he decided to go missed as well. In the mean time the second B737 decided to come out because company did; final was working the second B737 not sure what heading was assigned but he was climbed to 4;000 turning southeast bound. Final descended the second B737 to 1;600 and continued to a southbound heading. Separation was lost. Don't try and cram airplanes into an airport when extreme weather is imminent; stop arrivals before these problems arise.
