A weak lower- level trough is crossing the region and moisture trailing its axis should cause occasional cloudiness with a few showers across our islands this afternoon, increasing tonight. The High Pressure System should be re-establishing itself across the Atlantic; but lower-level moisture associated with shearline features on its southern edge, are expected across the Southern Windward Islands including St.Vincent and the Grenadines (SVG) this weekend.

A weak shear-line brought a narrow band of cloudiness with a few showers across the northern portion of mainland St.Vincent during the latter half of this afternoon. Cloudiness should be reduced by early morning (Thursday) and no significant shower activity is expected tonight. Another weak shearline/trough is now expected across the region by Thursday evening with a few scattered showers.

A  High Pressure System is centered across the far eastern Atlantic and lower-level shearline/trough features within its wind-flow along the south-western edge can be expected across our area. Tonight into Wednesday, moisture converging at the lower to mid-levels as shearline features could result in scattered showers across our area. Another weak shearline/ trough is expected Thursday into Friday.

Weak shearline/trough features along the southern edge of the Atlantic High Pressure System are propagating across the island chain. Over the next few days, these lower-level shearline/troughs are expected to cause some cloudy skies with periods of light rain and light to moderate showers accompanied by some gusty winds. Favourable conditions associated with an upper-level Jet-entrance region; could provide some enhancement to shower activity causing unstable conditions on Monday,

A High Pressure System is dominant across the Atlantic Ocean area, but couple weak trough/shearline features are along its southern edge propagating across the island chain. Cloudiness with shower activity should be decreased across our area by this evening, but a few scattered showers are expected again overnight into Sunday. By late Sunday, another weak trough should be approaching the islands bringing showers on Monday.

The Atlantic High Pressure System is dominant across our area, but couple weak troughs induced by a low pressure system in the Eastern Atlantic are propagating across the island chain. A few showers can be expected tonight with brisk trade-winds and occasional strong gusts. Occasional showers are expected to continue Friday and throughout the weekend. 

The Atlantic High Pressure System is dominant across our area, with brisk trade-winds and occasional strong gusts expected across our area. A couple troughs, being induced by a low pressure system in the Eastern Atlantic are expected across our islands. Some showers are expected across our area tonight into Thursday and models still project rainfall accumulations across St.Vincent and the Grenadines (SVG) to be near 20 - 30mm or ~ 1inch.

A low pressure area is expected to deepen just off the Continental US in the Western Atlantic Ocean tomorrow and be steered northward. Meanwhile, a couple troughs and shearline features are being induced by a low pressure system in the Eastern Atlantic. A weak shear-line should be across our area with occasional cloudy skies and a few scattered showers by tomorrow, Tuesday

The Atlantic High Pressure System is across the region and cloud patches within its wind flow could bring a few showers across our islands by evening/tonight.By Tuesday, a weak low-level shear-line could result in occasional cloudy skies and a few scattered showers across our area, shifting southwards of the Grenadine Islands by Wednesday.

A couple troughs should be crossing the islands Thursday into Friday. 

Over the next couple days, the south-easterly flow should continue across our islands with speeds ranging 15 – 35km/h. This could result in moisture convergence with patches of low level clouds causing occasional cloudy skies and scattered showers.  A couple weak lower-level shearlines and mid to upper level features should support such shower activity across our area this weekend.
