Hot spell to end with a thundery cooler change

Brett Dutschke, Wednesday November 19, 2014 - 13:07 AEDT

A hot spell will be broken up by cooling showers and thunderstorms before it comes to a rainy, thundery end early next week.

The hot spell will last five days over most of New South Wales, longer and more intense than last week's, making it the longest, hottest November spell since 2009.

From this Thursday to next Monday maximum temperatures will run five-to-ten degrees above average across the state and ten-to-twelve degrees above average in the central-west.

Gulgong, Wellington, Scone, Wellington, Dunedoo and Peak Hill should average a maximum of 38-39 degrees, 11 degrees above the long-term average.

NSW's hottest area will be the northwest where Mungindi, Walgett, Lightning Ridge, Brewarrina, Bourke and Wanaaring will average 41-42 degrees, about nine degrees hotter than the long-term average.

The heat won't be confined to the west, much of the ranges below about 1000 metres and the coast should average about 30 degrees.

During the hot spell, brief cooling relief from showers and storms will mainly occur on the northern ranges and slopes but during the weekend parts of the west and south will be affected.

A near-stationary low pressure trough in the north is filling up with moisture, bringing potentially 30 millimetres or more in any storm. This trough will merge with another crossing from South Australia from the weekend. These merging troughs will meet early next week, causing showers and storms to become heavier, more widespread and turn into thundery rain.

It looks like being the most widespread rain for the state since early spring or winter.
