The passage of a low pressure trough with a cold front brought scattered thunderstorms which brought useful moderate to heavy rainfalls at several places in our region last Thursday and Friday the 19th and 20th October.
Some notable heavy falls were at Yarrawonga, 42.2 mms to Friday morning which was the heaviest daily rainfall for October since 1975, Corowa, 47.6 mms which was the heaviest daily fall for October since 2010; White Cliffs , 48.8 mms which was it's heaviest daily rainfall for October since 63.5, mms in 1959 ; Wanaaring with 70.1mms to last Friday morning was it's heaviest daily fall for October since 80 mms on 23rd October 1949.
Many places including Moree and south from Gilgandra to Forbes have all exceeded their monthly averages this month. Further variable rain and thunderstorms are expected during the last week of October as the disturbance with thunderstorms now over the SW corner of WA progresses slowly eastwards this week.
The heavy rain in Eastern parts of QLD mainly along the coast has eased during last weekend but Bunderberg has received a massive 547 mms this month; more than double the previous wettest October of 1953; Sandy Cape has received 506 mms this month; also more than double the previous wettest October of 229 mms in 1984.
Maryborough's 434 mms is the wettest October since 498 mms in 1882. Sydney that year had it's driest ever September until this was broken this year.
Heat is building up again in the Pilbara the last few days. Marble Bar recorded 43.8 last Friday but this is still about two degrees below the record hottest October day of 46 in 2002. At this stage this excessive warmth is unlikely to filter into our region in the immediate future.
