The chance of elevated showers and thunderstorms late tonight until morning tomorrow with relatively high amounts of moisture and relatively steep vertical lapse rates ahead of an an upper level trough/disturbance.The low level wind convergence at around 850-750 hPa level could act as a trigger.
A more southeasterly pressure gradient from Wednesday but there would be plenty of clouds on Wednesday with plenty of low level moisture,hence possible drizzle in the morning.
Sea breezes likely return from Thursday with the west coast trough inland.
