AFTER four long, dry months the Sunshine Coast has smashed the October rainfall average of 70mm in just the first four days of the month with the promise of more to come over the next week.

Maroochydore and other coastal areas have received 106mm for the month so far although falls of over 200mm have been recorded in parts of the hinterland and at Noosa Heads.

A weakening trough inland will ease the chance of more than a late afternoon shower today.

However Bureau of Meteorology forecaster Harry Clark said the system would strengthen again Friday improving the likelihood of thunderstorms and unsettled weather through to next week.

The longer-term outlook is less certain with only a 50-50 chance of more or less than average rain through November and December.

Mr Clark said the strengthening trough would push back eastward on Friday bringing with it the possibility of showers and storms for the Darling Downs and the Granite Belt before drifting further towards the coast in the late afternoon or evening.

He said while there would be a greater focus to the south and west of the Sunshine Coast, there was the chance the rain would also reach this region.

There were showers and isolated storms over much of the Sunshine Coast on Wednesday but the system died as it got closer to the coast.

Falls to 5mm were recorded however Mr Clark said they would have been heavier in places.

The weekend will bring a southerly change on Saturday but its impact would be determined by the timing.

Mr Clark said if it arrived early in the day there would be no chance of thunderstorms, however they would become more likely the later it pushed into the region.

Sunday should be cooler, down to 26 degrees after reaching 30 on Friday and 27 on Saturday.

Modelling shows the chance of showers ramping up on Monday and Tuesday but Mr Clark cautioned the forecast was a long way out and subject to change.

Winds will reach 15-20kmh from the east through the middle of today before becoming light later on with a chance of a shower in the late afternoon.

Friday will be hot and steamy with the chance of showers and a gusty evening thunderstorm with winds from the north north-west at15-20kmh swinging north north-east at 15-25kmh and then north north-west at 15-20kmh later in the day.

On Saturday winds would be light early before the south-easterly change kicks in with gusts to 30kmh.

However Sunday they are expected to swing east north-east after being light earlier in the day.
