Thundery showers expected in first half of January 2021: Met Service

On most days in the first two weeks of 2021, moderate thundery showers are expected in the afternoons. This may extend into the evenings on some days.

SINGAPORE — Moderate thundery showers and windy conditions are expected in the first two weeks of the new year, the Meteorological Service Singapore (MSS) said on Thursday (Dec 31).

On most days in that fortnight, moderate thundery showers are expected in the afternoons. This may extend into the evenings on some days. 

On a few days, large-scale convergence of winds in the region could bring heavy and widespread thundery showers over the country.

"Overall, the rainfall for the first half of January 2021 is expected to be above-average over most parts of the island," MSS said. 

The monsoon surge in early January is also expected to bring cooler daily temperatures of between 22°C and 31°C on a few days. 

For the rest of the fortnight, daily temperatures are forecast to range between 23°C and 33°C. The mercury may reach a high of 34°C on one or two days, said MSS.

DECEMBER REVIEW

This month, "short duration" moderate to heavy thundery showers fell over Singapore mostly between the afternoons and evenings, with showers stretching into the night on some days. 

On Dec 26, strong solar heating of land areas, coupled with localised convergence of winds, brought heavy thundery showers over many parts of the country. 

The daily total rainfall recorded on Dec 26 was 108.4mm at Mandai, the highest total rainfall in a day for this month. 

Daily temperatures in December ranged between 22.2°C and 35.1°C.

The highest daily temperature of 35.1°C was recorded in Admiralty on Dec 25, while the lowest temperature of 22.2°C was recorded in Sembawang on Dec 28.

"Many parts of the island recorded near-average rainfall in December 2020, except for a few parts of western Singapore where rainfall was below average. Around the Chua Chu Kang area, rainfall was 39 per cent below average," said MSS. CNA
