Summer is set to end with some wet and wild weather for the east coast with heavy rains forecast in Sydney every day for the next 10 days.
Morgan Pumpa from The Bureau of Meteorology (BoM) told Yahoo News Australia that severe thunderstorms are predicted, increasing the chance of heavy rain, damaging winds and large hail in parts of New South Wales.
"A trough is moving over the eastern parts today and over this week and deepening, and that's bringing the likelihood of severe thunderstorms for parts of the Hunter and Central Tablelands as well as Western Sydney," Ms Pumpa explained.
"So that possibility for severe thunderstorms also continue tomorrow for the central west as well as central parts of inland New South Wales."
The heaviest rainfall is expected on Tuesday over coastal locations, with heavy falls that may lead to flash flooding, mainly over Sydney and Illawarra districts.
Thunderstorms are expected to continue into Wednesday next week with the chance of storms and showers each day in northern, central, eastern and southern areas of NSW.

La Nina caused increased rainfall over the summer
Sydney can expect 50mm rain by Wednesday, with heavy rain and damaging winds predicted people are being advised to keep an eye on the radar due to possible flash flooding.
While unlikely, Sydney could see 100-150mm of rain by Wednesday, Weatherzone told Yahoo.
The La Nina weather event led to increased rainfall in NSW in January and most of February.
"Median rainfall is likely for parts of northern and eastern Australia for March and March to May," Ms Pumpa said.
BoM predicted an 80 to 100 per cent chance of rain every day between Monday and Sunday for Sydney, with temperatures to sit between the mid and high 20s for most of the week.
Storms predicted for WA, NT and QLD
The rest of the country may also see showers and some storms.
A broad low pressure trough over northern Western Australia, the Northern Territory and Queensland is triggering showers and storms for Monday and Tuesday.
The trough in WA is drawing hot, gusty winds to the west coast. A front is bringing a burst of strong showery winds to Tasmania and onshore winds on QLD's coast bringing a few showers.
Despire some wet weather, it will still feel like summer around the country; with minimum temperatures forcast likely to be warmer than average over the next two weeks
WA saw some record-breaking temperatures over the summer, with Sunday, February 20 Perth’s 31st day at or above 35C so far this summer.
There have also been 13 days at or above 40C this season, smashing the previous summer record of seven 40C days in the summer of 2015/16, according to Weather Zone.
"For [WA] it's been quite dry over the last week, as well as the week coming," Ms Pumpa said.
“So we’ve got some cloud about, so temperatures aren’t getting to record highs but the clouds are keeping the minimum temperatures higher. The maximum temperatures are around average [Australia wide], but in the east they’ve been below average recently.”
