The city is, according to Weatherzone.com, set to be lashed by as much as 50 millimetres of rain across Wednesday and Thursday this week.
The worst of it is forecast to roll through Orange on Thursday, with a 90 per cent chance of rain. There's anywhere between 20mm and 40mm on the radar.
On Wednesday, there's also a 90 per cent chance of rain, however, there's between 5mm and 10mm on the forecast.
Should Orange receive the maximum amount of 50mm, it'll be one of our wettest 48-hour periods of the year, and could near the 55mm we copped on April 27 and April 28.

There was 77mm recorded across July, which is a little below average for the middle of winter in Orange.
