A WARM air mass will pass over NSW during the next couple of days before a brief burst of showers and thunderstorms sweeps across the state.
Northerly winds ahead of an approaching low pressure trough will cause temperatures to spike across much of NSW today and tomorrow.
On Thursday, the mercury should reach around 40 degrees Celsius in far western NSW and the low-thirties over the slopes and plains.
This heat will shift further north and east on Friday, causing temperatures to climb along parts of the coast, ranges and across the northern inland.
- Summer just got soggy for the Central West
- Soggy end to week for eastern parts of NSW
- State set to sizzle as a heatwave settles in
Fortunately, the humidity won't be too low and wind won't be too strong as temperatures rise in the coming days.
This will help suppress fire danger ratings across the state.
Following the heat, the low pressure trough will trigger showers and thunderstorms in most districts of NSW on Friday and Saturday.
This wet and stormy weather will initially develop over southern and western NSW on Friday, before spreading over the state's central districts during the afternoon and evening.
On Saturday, showers and storms will mostly contract to central and northeastern NSW, although showers remain possible over all but the southwestern inland.
Some of the thunderstorms on Friday and Saturday could become severe, so make sure you check the latest warnings in your area.
Drier weather will return to most of the state from Sunday, with temperatures remaining near or slightly below average for most of the state into the beginning of next week.
