Jyväskylä has had its warmest start to October in the last 5 years in terms of average maximums. Including yesterday's maximum of 9.7C the average maximum so far stands at 10.7C, 1C warmer than 2011 at the same date and 4.5C warmer than 2009.
There have been 8 days above 10C so far with a maximum of 14.4C on October 7. This is compared to no days above 10C in 2009, 5 in 2010, 7 in 2011 and 5 in 2012. The monthly maximum also topped the previous highest maximum for October since 2009, the 14.1C measured last year.
Not only has it been the warmest start in terms of the average maximum, it has been the second coldest for average minimums. Only 2009's chilly average minimum of -3.3C after the first 13 days is colder than this year's 1.1C. Last year's 4.9C was the warmest in the 5 year period. Currently it's hovering between -4C and -5C in Jyväskylä though and the next few days are forecast to be much cooler than the previous week also. A prediction for only 1C on Thursday and Friday currently stands with snow forecast on Friday.
I'm heading back to Jyväskylä arriving Thursday morning, so I guess I'll get to experience it myself. It'll be a big change from the 36.2C recorded at Sydney Airport yesterday. Strong northwesterlies bringing warm air from north and central Australia were again responsible. Another strong southerly change hit just before 8:30pm dropping temperatures. A maximum gust of 82km/h was recorded.
There was some storm activity up and down the coast of NSW yesterday evening as a low pressure trough and cold front moved east across the state. I didn't pick up any lightning or thunder in Sydney, but 0.2mm fell just before midnight, with a further 3.0mm in the early hours of this morning.
