Dry spell and warm days continue

June 26, 2017
The long spell of dry weather and above normal warmth each day has continued last week and is expected to continue up to near the end of the month in our regions.

 However, there are signs of a change approaching. Perth last Thursday 22nd , received 61 mms rainfall and this was the wettest June day there since 1986. Since then an upper level feature has developed over inland parts of WA with some light rainfalls, 6 mms at Warburton which had a cold day with a maximum temperature of 14 degrees.

This upper level low may intensify and provide useful rainfalls to some parts of our regions by next weekend. This month has been noteworthy that daily maximum temperatures have been above normal almost everywhere across the nation.

It will be warmest June on record at Perth and Hobart and at many other places across the Nation. It has been the driest June on record at Adelaide and the driest at Hobart since 1979.

To date many places in our regions are approaching their driest ever June. Coonabarabran's 2.2 mms is so far the driest June there since 1971. At Broken Hill where I am currently staying with Rae Sheppard, the first half of this year has been the driest since 1986. Wilcannia and White Cliffs have both had their driest first 6 months this year since 1965.

Melbourne, Adelaide and Hobart have all experienced the lowest run of wind for any month on record; this is due to the presence of stagnating strong high pressure systems.

It is anticipated that the strong high pressure systems will not be as strong during July. This indicates a significant rain event by mid July. There was much needed July rainfalls in our regions in 1971 and 1986.
