What can be said about the destination airport at 2030 UTC if CAT II ILS minima 350 m RVR, 100 ft Decision Height are being considered?

050 16706 Meteorological Information

Still open because the decrease of the visibility below the CAT II minima will be a little bit later than 2030 UTC. Has to be considered as closed. Still open until 2200 UTC because the weather change is not completed before 2200 UTC. Open the whole night because 300 m of visibility corresponds to at least 900 m RVR.
