Storms hit Sydney, more typical autumn weather for Jyväskylä

Sydney Airport recorded its warmest minimum yesterday in almost four months. The warmth seen on Wednesday led to rather warm overnight temperatures as it barely dropped below 18C in the early hours of September 25. A change late in the day, however, dropped the mercury to the daily low of 15.9C. Storms and showers also arrived along with the southerly change.

Wednesday September 24 recorded the second warmest temperature of the month so far. The 25.7C maximum was only the third above 25C this month. Yesterday was still fairly warm also with a top of 24.0C.

The Bureau of Meteorology issued a storm warning for the Sydney region yesterday afternoon as several isolated concentrations of very heavy rain and small hail made their way east across the city.

Despite the menacing appearance of the storm clouds, rainfall totals weren't especially high. The Airport recorded a total of 4.4mm yesterday. In fact, rainfall across the Sydney region was fairly evenly distributed. The highest total, 8.4mm, was seen at Terrey Hills. Penrith in the west, Camden and Sydney Olympic Park each recorded 6.6mm. Observatory Hill only saw 2.0mm. The Airport's total was the highest daily figure in just over two weeks.

Today was much cooler in Sydney. Temperatures at the Airport only reached 18.9C, while Observatory Hill was a little warmer at 21.7C.

Tuesday's very cold day in Jyväskylä, of which the 3.0C maximum was the lowest seen since April 1, almost five months ago, has given way to a gradual increase in daytime temperatures up until today. September 24's maximum of 5.9C, however, was still the fifth lowest since at least 2009. The 24th also saw another 1.5mm added to the monthly rainfall total.

Yesterday's minimum of -1.6C was the lowest seen this month and the coldest since May 15, but it rose to 8.8C by the late afternoon. Temperatures this morning remained above 5C and they climbed above 12C just after 3pm.

Rain is currently moving in from the west and should reach Jyväskylä around 9pm this evening. Yesterday was dry but 0.2mm was already recorded early this morning at Tikkakoski.
