    The cold snap is expected to continue through into the up coming week in New South Wales and Victoria, as low pressure to the south–east of the region continues to pull in cold air from Antarctica. Further cold frontal systems and strong cold southerly winds associated with the low will deliver more rain, and snow throughout the week. The Blue Mountains and Australian Alps will likely see heavy snowfall and blizzard conditions.

    The unusually cold temperatures will be in part caused by a cold frontal system tracking eastwards across New South Wales and Victoria. However, there is some suggestion that the particularly strong El Nino this year accompanied by a strong MJO (an enhanced area of convection which starts in the Indian Ocean and works its way around the globe into the Pacific Ocean) is encouraging more extreme weather about the globe.

    Extreme weather can also be seen in other parts of the world with high rainfall totals in Northern America. July 7th was Indiana’s seventh wettest day on record with 112.5mm falling in 24 hours.  To the west of Indianapolis there were 24 hour totals of 114 to 127mm.

    Here in the UK things are looking a bit warmer on Sunday 12th of July but just as unsettled with blustery showers or longer spells of rain in southern and central England as well as Wales. It will be a mixed day elsewhere with sunny spells and showers. Further rain will push across the UK from the west on Monday.
