Sydney had a warm night, but a gusty cool change swept through during the morning as thundery showers began developing.
A severe thunderstorm warning was issued for Sydney late this morning with western suburbs the most likely to receive severe storms in the Sydney region.
As thunderstorm cells develop on the ranges and move into western suburbs they are likely to become less defined as they move east. Eastern parts of Sydney should receive a gradual increase in showers with stray lightning strikes. Thunder and lightning should continue on and off into the evening, similar to Christmas Day.
Gardeners may be shocked to have so much rain after such a dry period. By tonight Sydney will have gained almost as much rain in the past week than it did in the past four months combined.
Winds are likely to stay fresh and gusty through the day with winds likely to become strong at times on the coast.
Overnight winds will remain strong near the coast as thundery showers begin to ease.
Tomorrow morning winds will remain fresh and gusty in the east with a few showers lingering in the morning. By the afternoon there is likely to only be the odd shower in the Sydney Basin.
Sunday will see an improvement in the weather with slightly warmer conditions and only a low chance of a morning shower. Winds will also be a fair bit lighter and some sun should poke through.
