WEATHER UPDATE: THE HEAT IS ON

Despite high level cloud moving in today across much of NSW temperatures remain high, especially inland.

Storms across the Northern Tablelands have been a real feature this week and will continue to be so until the hotter drier air moves in on Thursday.

So Wednesday is going to be another hot, cloud affected day with afternoon storms affecting areas on and about the ranges and Upper Hunter.

From Thursday conditions are going to become even more dangerous as Spring goes out under scorching conditions which will roll over into the first day of Summer on Saturday.

The worst of the heat will be felt across the NW, Hunter and MNC with the potential for catastrophic bushfire conditions.

NE winds will help fan the coast with the run of little to no swell continuing.
