Widespread rain events on the way

By Peter Nelson on March 21, 2017

The continuation of the current warm to hot spell in our regions which has persisted since the end of February is now expected to lead up some widespread moderate to heavy rain events, with thunderstorms in the next few weeks. 

Some places have already had heavy rainfalls with Moree 113 mms, it's heaviest March rain since 2000, Narrabri with 160 mms it's wettest March since 1963 and Coonabarabran Airport with 153 mms it's wettest ever March in 16 years of records. 

Bendigo is having a record long hot March Spell to date and is approaching the record hot March of both 1893 and 1882. 

Both 1893 and 1882 saw heavy widespread rain near the end of March and again in early April in our regions. 

Minimum temperatures have also been noticeably above the March normal not only in our regions but also along coastal towns in Northern and Eastern Tasmania , in East Gippsland and along the NSW Coast where heavy rain fell last week. 

Port McQuarie with over 300 mms had it's heaviest March rain since 1974 and Smokey Cape with 217 mms last Thursday 16th March had it's wettest March day since 1963. 

The Coastal town of Wynyard in Northern Tasmania has to date had minumum temperatures 4 degrees above the March normal and this is the highest for March since 1974. 

Low Head near Devonport, St Helens and Swansea are all having their highest mean minimum temperatures for March since 1956, 1974, 2001 and 2010. 

At Gabo Island, the Mean minimum temperature this month to date is 16.8, three above normal and looks set to break the March 1974 record of 16.4. 

The first three of those four years listed above did see heavy rain events during the last week of March, early April and late April in our regions. 

The elongated zone of High Pressure south of the Continent is still yet showing no signs of breaking down; its now more than 4 weeks since the last cold frontal passage, a very unusually long time indeed.
