Whilst vast areas of NSW had a quiet night last night, the North West Slopes and Plains had a livelier affair, with a low pressure trough bringing storms and heavy showers.

A few isolated storms started proceeding across northern parts of the state in the late evening on Saturday, however it wasn't until around 2.30am that a line of storms about 200km long developed in the Narrabri area.

Between 2am and 4am there were around 4600 lightning strikes within 100km of Boggabri, with just over 760 of these ground strikes. As well as lightning the storms delivered heavy showers, with Narrabri picking up nearly 17mm in the 2 hours from 2am, by 27mm by 8am this morning.

The line of storms continued moving southeast over the next couple of hours reaching the Manilla area before the system weakened. By the time it arrived at Tamworth rainfall had eased, with the town only picking up 7mm in the two hours from about 7am.

Further isolated storms are possible over the next couple of days, with some models indicating an increase in instability and the potential for greater activity from Tuesday, so make sure to stay up to date with the latest forecast.
