Pilbara's balmy nightSam Brown, Saturday October 26, 2013 - 17:58 EDT
Fans were a valuable asset last night in Western Australia's Pilbara as temperatures soared well above average.
Port Hedland has recorded its hottest evening (25.7 degrees) since April this year at almost ten degrees above the October average. Mardie had its warmest night since May being eight degrees above the October average. Onslow reached 24.9 degrees overnight, making it the hottest October night since 2006.
These temperatures aren't usually seen this early in spring, and are generally more consistent during the late summer months of January and February.
A low pressure system and trough deepened over the region allowing clouds to build. These clouds combined with a very hot air mass for this time of year to produce the balmy night.
The heat at the surface also helped to trigger thunderstorms about the Pilbara. More than 800 lightning strikes have been recorded since Friday morning.
A lingering hot air mass and evening cloud cover will keep minimum temperatures well above average in the coming days, although instability may continue to produce isolated thunderstorms. Daily temperatures will reach into the mid-to-high thirties until at least mid-week.
