Example
TAF EDDM 011100Z 0112/0218 25010KT 9999 SCT030 TEMPO 0114/0118 4000 SHRA BKN014
In the example, Munich is forecast from the 1st 12 UTC to the 2nd 18 UTC with wind 250° at 10 kt, good visibility and scattered cloud at 3,000 ft. Between 14 and 18 UTC, temporary rain showers may reduce visibility to 4 km with broken cloud at 1,400 ft.
In practice
Plan with the worst condition inside TEMPO and PROB groups for your arrival window, not with the main forecast line.
