Applicable vs Planning minima
A destination forecasting this kind of conditions requires 2 destination alternates to be nominated for a flight to be legally dispatched there if ETA was anything between 0500Z and 0800Z:
TAF EBLG 140530Z 1406/1512 04006KT 2000 BR BKN003
TEMPO 1406/1407 0100 FG BKN001
EBLG offers CAT III approach with requirement of 125m RVR, a condition which is not fulfilled at time of ETA --> select 2 destination alternates!
