Narrative:
The airspace was impacted by WX. The controller was getting inbnds other than normal operations. An small transport X and an large transport Y came within 4 1/2 mi and 300' of each other. The controller saw the situation prior to the conflict alert being activated. The controller turned and expedited the small transport Y descent to avoid losing standard sep.
