What does a sky cover condition of 2/8ths cloud cover at 2,500 feet and 7/8ths towering cumulus cloud cover at 5,000 feet appear as in METAR?

A sky cover condition of 2/8ths cloud cover at 2,500 feet indicates that there are a few clouds at that altitude, which is designated as "FEW" in METAR reporting. The “025” specifies the height of 2,500 feet above ground level.

At 5,000 feet, a cloud cover of 7/8ths towering cumulus indicates that the sky is predominately covered by these clouds, which is reported with "BKN" for broken clouds, as broken clouds are classified when between 5/8ths and 7/8ths of the sky is covered. The “050” denotes the height of 5,000 feet.

The presence of towering cumulus clouds is additionally noted with "TCU" appended to indicate this specific type of cloud formation.

This analysis leads to the correct reporting format that combines these observations into a single METAR code: "FEW025 BKN050TCU." This accurately reflects the conditions at both altitudes mentioned in the question.
