YESTERDAY'S widespread cloud cover over Tamworth finally delivered when it started raining about 4pm.
But, late yesterday, Weather Channel presenter Duane Strauss said the system might produce a few showers, but there would be less than 5mm in it.
"What we're seeing is a cooler change being funnelled up from the south and that's been producing a few showers," Mr Strauss said.
Coonabarabran had received 4.2mm since 9am yesterday but "we didn't see much rain across NSW", Mr Strauss said.
"This is all thanks to a thunderstorm system ... (triggered by) a hot pool of air sitting in Central Australia," he said.
The Bureau of Meteorology was forecasting possible thunderstorms for late yesterday in the North West Slopes and Plains. This followed strong, gusty and hot westerly winds around the district on Saturday.
Yesterday, when the cool change hit, Tamworth dropped from 31 degrees Celsius to 27 degrees between 2pm and 5pm.
Tamworth should expect a week of vacillating temperatures hovering around the mid- to high 20s, with a top of 32 degrees forecast for Thursday.
Moree should reach 30 degrees today after an overnight low of 15; daytime tops should be a minimum of 30 degrees all week, except for tomorrow when it will reach 28 degrees.
In Narrabri, it's a similar story, with 29 degrees forecast for today, 28 for tomorrow and 30 for Wednesday, heating up to 34 on Thursday.
But no rain is forecast for either Tamworth, Moree or Narrabri this week, with rain expected to fall just to the east.
Yesterday, between 9am-3pm, Armidale received 0.4mm, Blue Nobby 1mm, Coonabarabran 4.2mm, Dunedoo 2mm, Mullaley 0.8mm and Narrabri 0.4mm. Between 4pm and 5pm yesterday, Duri received 0.3mm, Coonabarabran 2.6mm and Mullaley 0.6mm.
The bureau forecasts a less-than-10-per-cent chance of rain until Sunday for Armidale, Inverell, Moree and Tamworth as a high dominates the weather, bringing a scant chance of rain.
