12:30PM Monday 28th January 2019: Low Level Convergence Bring Cloudy Skies, Isolated Showers Through Evening. By Late Evening, Drier & Cool Conditions Expected.
Low level cloud patches, resulting to convergence on the western side of a ridge of a weak high pressure in the Central Atlantic, are moving across Trinidad and Tobago, bringing isolated to scattered showers and partly to mostly cloudy skies.
By the late evening into the night, drier air (low amounts of low-level moisture) will move across Trinidad and Tobago. This drier air will limit cloud coverage and enhance cooling at the surface overnight.
Throughout the week, with mild amounts of low-level moisture pulsing across the region as the Central Atlantic high-pressure system weakens, wind speeds are also expected to weaken. This means that isolated showers by the late morning through the afternoon will be possible, and cool nights are expected.
By Thursday, a new high pressure system in the Eastern Atlantic will begin to dominate the weather across the Caribbean, bringing definitively drier conditions to the later part of the week.
Maximum temperatures are forecast to be 30-31°C across both islands. Lows are expected to be 20-23°C across Trinidad and Tobago through the week. Interior parts of the islands may see temperatures dip below 20°C. By Wednesday, lows are likely to be below 20°C across Trinidad.
Seas, until Thursday, will be slight to moderate with waves up to 2.0 meters in open waters, and calm in sheltered areas. E winds are expected, between 15-20 knots.
