The upper levels remain relatively dry across our area supporting stable conditions. A cyclonic circulation within the lower levels is across our area, but relatively dry mid to upper levels maintains the stable conditions.
Hence, Fair skies tonight with thin low level clouds may only bring the odd brief shower. A weak surface to low level trough (easterly wave) is expected to cross the area tomorrow evening into Wednesday, which may generate a few scattered showers. Models indicate that any rainfall accumulations may be concentrated across the Grenadines Wednesday as weak instability lingers. The High Pressure System is expected to rebuild across the area later Wednesday with the return of fair conditions continuing Thursday.
Gentle (12-19km/h) east north-easterly breeze tonight could be occasionally light and variable. A gradual increase to moderate (20-28km/h) breeze is anticipated on Wednesday as the High Pressure builds; with the southern-most Grenadines experiencing fresh (29-38km/h) breeze.
Visibility continues to be good until a rapid increase in dust concentrations on Wednesday should be noticeable; dust concentrations ranging 80-160 ug/m**3 are expected to reduce visibility and air quality into the weekend.
