Explanatory notes:
Weak southwest monsoon break conditions persist until Monday then the southwest monsoon possibly strengthens but still plenty of uncertainty.Anabatic lifting of sea breezes will trigger showers and thunderstorms over the hills and foot hills during during the afternoon/evening hours throughout the forecast period.Light steering flow persists tomorrow and then light onshore steering flow until possible strengthened southwesterly steering flow from Tuesday but still plenty of uncertainty.Forecast still gives more weightage to the ECMWF model with the GFS model trending towards the ECMWF solution.

Kota Kinabalu weather forecast produced at 8:20 PM Wednesday June 27:

Explanatory notes:
Weak southwest monsoon break conditions persist until Monday then the southwest monsoon possibly strengthens but still plenty of uncertainty.Anabatic lifting of sea breezes will trigger showers and thunderstorms over the hills and foot hills during during the afternoon/evening hours throughout the forecast period.Light steering flow persists throughout the forecast period until possible strengthened southwesterly steering flow from Tuesday but still plenty of uncertainty.The ECMWF 00Z and ACCESS Global 00Z as well as JMA predicts onshore steering flow throughout the entire forecast period but the GFS predicts offshore steering flow from Thursday.In this forecast I have given more weight towards the ECMWF 00Z solution and hence only the slight chances of rain over the city center.
