Period of validity is stated as 13:00 UTC day 23 until 22:00 UTC day 23 (2313/2322). 
Initial weather conditions are forecasted to be:

• 24014G32KT = wind 240° at 14 kt gusting to a maximum of 32 kt
• 4000 = visibility 4000 m
• +TSRA = heavy rain and thunderstorms
• SCT005 = scattered clouds at 500 ft above the airport.
• BKN015 = broken clouds at 1500 ft
• BKN020CB = broken clouds at 2000 ft and cumulonimbus

=> The above describes typical conditions at a cold front: gusty conditions, heavy rain and thunderstorms, SW winds and broken layer of clouds with Cumulonimbus.

A change of permanent character is expected to occur on day 23 at any time between 14:00 and 16:00 (BECMG 2314/2316). After the change occurs, the following conditions are to be expected:

• 29012KT = wind 290° at 12 kt
• 9999 = visibility 10 km or more
• BKN030TCU = broken clouds at 3000 ft and towering cumulus
• SCT100 = scattered clouds at 10000 ft

=> The above describes typical conditions behind a cold front: winds veer and speed decreases, cloud base are lifting with occasional CBs.

Next changes expected are of temporary character (TEMPO 2316/2319) => which means that the listed conditions can occur on day 23 at any time between 16:00 and 19:00 UTC, but are not of permanent character and may occur momentarily, for a max of 1h at each time. Thereafter, the conditions will revert back to how they were previously.

• SHRA = moderate showers of rain

=> We can conclude that the passage of a Cold Front is being described in this TAF. Note that this chart is valid for 1500 UTC. A 1500 UTC, as we have discussed, the cold front has already passed. The only airport located behind a Cold front is EINN.
