More temperature records for August broken

The last few days have seen more maximum temperatures records for August at places across the Northern part of the Nation. Daly Waters recorded 37.8 ,( 100 F ) , last Saturday 19th August and this broke the previous August high of 37.5 in 1970.

New records were also set at Borroloola, 37.7, and at Palmerville, 37.2, braking the previous records in 1998 and in 1897 respectively at both places. Fitzroy Crossing recorded successive days of 38 degrees or more and this has not happened in August since 1998.

At the other extreme many places in our regions recorded severe frosts on Sunday morning, 20th August and their lowest temperature for this winter. Parkes with minus 5.6 recorded it's lowest August temperature since minus 6.0 in 1999. Dubbo with minus 4.9 recorded it's lowest August temperature since minus 5.2 in 1995.

Both places recorded their lowest temperature for the second half of August in over 100 years of records. The Southern Ocean low pressure belt which has been more active than usual the past weeks was responsible for these record August temperatures generally.

A very deep low pressure centre passing through Bass Strait brought very strong winds to much of our regions and heavy rain to NE Victoria and few places in the Riverina. Very little rain fell north of Wyalong and the strong SW winds brought very low dew point temperatures.

At Moree the Dew point temperatures last Friday and Saturday were very low at minus 5 and winds reached 60 kms per hour consistently during both days. The Southern Ocean low pressure belt has now weakened and a welcome change to warmer days is expected this week and this may continue up to early September.

Not much rainfall is expected in September at this stage, but heavier rains likely mid October. It has been a strange winter as many residents told me in St. George and Moree recently.
