Break from the wet weather for northern NSW

After a week of heavy rainfall in the New England region of NSW, residents will have a chance to bask in the sunshine for a day or two.

Last week a slow moving low pressure trough delivered unusually heavy rainfall to parts of the Northern Tablelands and Northwest Slopes, in what is usually one of the driest months for the region. Many towns received their normal total July rainfall or more in the space of several days. Moree received 81mm in four days, which is double their monthly average, marking their highest July rainfall in 11 years. Narrabri also doubled their normal monthly total with 62mm, as did Gunnedah, with 67mm. The heavy cloud cover during the nights also served to trap warmth near the surface, leading to unseasonably warm nights. Minimum temperatures were well above average, with Moree recording an overnight low of 15 degrees on Friday 13th, ten above the July average.

Due to the slow moving nature of the trough and prolonged rain periods, local water ways have risen significantly, with the Peel, Namoi and Gwydir Rivers all with minor flood warnings.

The heavy cloud and rainfall has now contracted to the north, thanks to a broad high pressure system that is dominating the state's weather conditions. Consequently, clear skies and low minimum temperatures returned last night and locals can expect to enjoy another sunny day or two, with cool mornings and overnight frost in places.

Another trough is expected to form over inland NSW on Wednesday, bringing showers to the region. Rainfall is not likely to be as prolonged or heavy, with only 5-10mm expected. The trough should move east fairly quickly, with showers easing again on Thursday.
