Wet weather for Jyväskylä, cool in Sydney

The last few days in Jyväskylä have seen quite a bit of rain. Almost 30mm fell over Monday and Tuesday. While this might seem quite low in comparison to rainfall in Sydney, if you look at averages for Jyväskylä it is quite high. In 2011 only 26mm fell during the whole month of November, and 36mm fell in 2012. The 1981-2010 monthly average stands at 54mm so we're on target at the moment to match or beat that mark.

The rain late yesterday was part of an intense low pressure system that moved north across the western part of the country. Along with the rain, strong winds were felt in many locations. I noticed a highest gust of 13m/s (about 47km/h) for Jyväskylä while monitoring observations on the FMI website. I may have missed a stronger gust though as FMI doesn't give daily recordings in the same way as BoM. Despite that, 13m/s is pretty strong for inland parts of Finland and a strong wind warning was in place yesterday. The strongest wind gust in Finland was at Kokemäki in the country's south west where a 23.3m/s (84km/h) gust was recorded.

November 6  in Jyväskylä was a showery day with hints of sunshine. Clouds cleared by late afternoon allowing the sun to briefly show itself again before setting.

Meanwhile in Sydney, it was the third coldest November morning since 2009. Around 6am this morning it was only 11.9C. Only November 2010 has seen lower minimums with two successive days at the start of the month dropping to 11.5C.

The start of the week was rather cool as strong southerly winds kept daily maximums below 20C with 18.4C and 19.6C recorded on Monday and Tuesday respectively. This was after the equal 6th warmest day of the year on Sunday. Temperatures peaked at 34.9C before a southerly change in the afternoon. Rain has stayed away for the time being although the current forecast shows the chance of a storm on Friday followed by showers and rain from Saturday to Monday.
