*** CONTRASTING JANUARY COMPARE TO LAST YEAR FOR THE HEART OF AUSTRALIA SO FAR *** Have a look at this folks.... As we mentioned a few weeks ago we saw here at JWC that the signs were for inland Australia not to be as hot as recent years as the upper ridge showed signs of weakening towards the end of December and disappearing unlike January 2014 and January 2013 with better prospects of moisture, more cloud, better rainfall and lower temps. Here is the upper ridge on New Years day last year cooking most of the interior of Australia so with any northerly winds for southern Australia or north westerly for eastern Australia, or north easterlies in south west part of the country these extreme temps would bring records eg Hobart and Sydney seeing their highest temps just a couple of the many records that were broken thanks to Angry Summer no 2 (First map which shows the stinking hot temps with the upper high ridge which is circled in white sitting over most of the country by the EC model Jan 1st 2014). The good news is without the upper ridge it has been replaced by stronger upper troughs, cloud, humidity, rainfall, temperatures have been a lot lower of late across the interior which is a complete contrast to this time last year.. Look how much of the red colour shades has disappeared compare to last year. (2nd image, upper chart by the EC model for tonight) As a result instead of getting temperatures up to 10-12c above average through the interior we are getting temperatures of up to 10-12c below average instead thanks to the moisture and rain, tropical in feed thanks to no upper ridge being there... This is at least a 20c turnaround from this time last year! Surface temperatures are in the mid 20s range in central OZ and even less further south instead of the mid to high 40s this time last year. The third map of Australia shows the massive cloud mass thanks to the upper trough and surface trough and no upper ridge, image is provided by BSCH & in image four you can see the maximum temperature anomaly for Friday January 9th how much cooler it was through central Australia & southern Australia in fact 90% of the Country was cooler than normal compared to the average, anything that is light green, darker green or blues, purples is cooler than normal thanks to the upper trough, cloud and rain.
