Plenty of rain, unseasonal humidity

THE arrival of heavy thunderstorms in North East Victoria on Sunday, November 17 effectively ended the long warm, very dry conditions which had persisted for many weeks.

And subsequent rains during last week have seen us endure very warm and humid conditions.

My ginger cat Lilly hasn't been the same since she was soaked during Sunday's storm when 33.8 mms was recorded in my gauge in an hour.

The rainfall was produced by a low pressure trough crossing our region.

A second low pressure trough crossed the Bight and interacted with two low pressure centers over inland Queensland, resulting in a period of unsettled conditions with thunderstorms which may continue into early this week.

Heavy rain was recorded at both Renmark and Mildura.

Renmark recorded 36mms to Monday morning, November 25 - the wettest November day since 76mms on November 17, 1961.

Mildura's 42mms was also the wettest November day since 1961.

The period July 1961 to November 1961 was very similar to this year.

This will also mean the absence of very hot days of over 35 degrees in our regions until the second week of December.
