More than 100mm for January as summer falls flat

Overnight Ballarat recorded 38mm, and with a further 18mm already falling throughout the day until 4pm, it means for the second time this month the city has seen more than a month's rain in a 24-hour period.

Officially our wettest day occurred back on January 3 when 40.8mm fell, but the majority of that fell when a storm pushed through between 9pm and midnight.

This rain event, which has so far dumped almost 60mm is the largest 24-hour rainfall we have seen this year.

Mount William in The Grampians had received more than 67mm, while other towns to record significant falls include Navarre with 53.6mm, Stawell with 52.8mm.

The dump of rain means that for the second consecutive January Ballarat has recorded much more rain than the usual 39.8mm.

Last year, January saw 70mm fall officially in the city's gauge, which is located out at the airport, however, just down the road, more than 200mm fell over areas around Lake Burrumbeet.

While the worst of the storm looks to have passed Ballarat and is now heading east, there is still plenty of moisture in the air with the rain expected to continue for most of the day.

But if you thought this was a wet January, you don't have to go far back to remember the wettest start to the year on record, which happened in 2011 when 206mm in January.

The humidity will disappear over the coming days and be replaced by cooler southerly with temperatures in the early 20s. Monday is the pick of the outlook at 27, but then Ballarat will experience a strong of cool days and temperatures hover around the high teens for much of next week.
