7 day weather forecast

    Effective as of 4:00 AM Tuesday June 8 2021

Explanatory notes:

Plenty of high and middle level clouds associated with tropical moisture aloft streaming from the strengthening subtropical low pressure system over the Indian Ocean ahead of an upper level trough.

The subtropical low pressure system strengthens with the strong upper level divergence and moves to the southeast to lies to the west of the region on Wednesday leading to strong gusty winds and possible raised dust if rain doesn't moisten soils sufficiently. The most likely scenario is first some elevated showers and thunderstorms in the morning with upper level divergence ahead of the upper level trough, then another round of showers overnight associated with an area of low level wind convergence followed by moist onshore flow.

Winds become lighter by Thursday morning as the low moves away from the region, however showers still occurring from time to time through the end of the forecast period with moist onshore flow, troughs within the vicinity and a possible cold frontal passage next Monday.
