BOM predicts rainfall totals to reach 50mm with severe storms

THE Sunshine Coast is heading for a very wet end to the week with the Bureau of Meteorology forecasting falls to 50mm were likely.

Nambour reached 36C on Tuesday as the building heat of the past few days peaked.

However, BOM forecaster Dean Narramore said totals in the low 30Cs expected on the coast didn’t eventuate due to the cooling impact of a stiff north-easterly sea breeze.

He said a strong, upper level trough moving into the region from the west was expected to combine with a moist, on-shore flow to produce solid rain.

“Thunderstorms may be severe,” Mr Narramore said.

Rain will develop Friday evening with Saturday expected to see falls in the order of 30mm to 50mm with isolated heavier totals.

The BOM has forecast a 90 per cent chance of rain Saturday and 70 per cent on Friday with temperature maximums falling to a two-below-average, 23C.

Expect a 24C maximum on the coast today with southerlies at 15-20km/h tending south-easterly at 15-25km/h.

Thursday will be partly cloudy, with a 40 per cent chance of morning and afternoon showers and winds from the south-east at 15-25km/h. Maximum temperatures were unlikely to climb above 23C.

Friday should bring cloudy conditions, a 70 per cent chance of showers through the afternoon and into the evening and the chance of a severe thunderstorm.

The BOM expected a cloudy Saturday with a 90 per cent chance of rain and heavy storms to not climb above 21C.

As the upper level trough moves through conditions will then improve Sunday with light winds, partly-cloudy conditions and a 23C maximum.

By Monday it should be mostly sunny with light winds and temperatures nudging 24C before they rose again to 27C on Tuesday.

Mr Narramore said the burst of heavy rain was just a moment in time with the general, background pattern remaining “pretty dry” heading into summer.
