In addition to the westerly winds aloft, the atmospheric sounding shows several key features.

Surface temperatures will be in the 20s today (70s in Fahrenheit) .

There is a very small temperature inversion at the surface, and winds are nearly non existent. The moist layer is fairly low, leading to some low clouds. There are 58.76 mm (more than 2 inches) of precipitable water, which should lead to some modest rainfall as the day goes on. Additionally, 1029 J/kg of CAPE also leans towards a propensity for rainfall.

As per the usual, there is currently rainfall over the outlying islands and sea. Additionally the Nausori and Suva areas are getting light rain, and should continue to get that throughout the day.
