Cold start to summer for Sydney!

Sydneysiders should make the most of today and Tuesday as they are likely to be the warmest days in a while!

Today is already shaping up to be a pleasant sunny day with 26-30 degrees with Tuesday forecast to reach 27-31 degrees.

After a warm night on Tuesday, the beginning of Wednesday will be a balmy 28-31 degrees before showers turn up from the late morning or early afternoon. There is also the potential for thunderstorms which may be severe. The wet weather will provide some cooling but a southerly change due on Wednesday night will lead to a significant temperature drop on Thursday.

Consequently, the first day of summer will feel like more like winter for Sydney with showers and just 20-21 degrees! Cooler than average summer temperatures in the low twenties are forecast to linger for at least another week from Thursday.

This cold and wet change for Sydney is part of a larger system that will affect most of NSW on Wednesday/Thursday. Of particular concern is the rain that is expected to fall over flood affected parts of north-west NSW with up to 50mm possible. While this rain event won't be as severe as last week, it is likely to lead to secondary flood peaks on some rivers.
