Heavy rain in Sydney this morning, forecast backflip for Jyväskylä

The early hours of this morning saw very heavy falls in Sydney's east. In only a matter of just over 4 hours, Sydney Airport received its highest daily rainfall total in almost 4 months. A total of 32.0mm fell from just before 1am until 5am; 20.6mm of that fell within the first 30 minutes or so.

Residents of Sydney may have noticed a fair amount of shower and storm activity off the coast in the past couple of weeks. A few hundred millimetres worth of rain has fallen 50-100km out to sea since the start of the month.

This morning, over 100mm fell off the coast between Sydney and Wollongong. On land, Observatory Hill recorded 27.8mm to 9am, also the highest 24 hour total since November, and Canterbury received a drenching with 48.6mm. That was the highest daily recording there since June 30 last year.

Temperatures were a bit cooler today at the Airport, breaking a 6 day streak above 28C. Observatory Hill managed to top 27.0C, but southerly winds kept the maximum down to 24.1C at the Airport. The daily minimum of 18.3C was also the lowest in more than a week.

Colder weather is still on the way for Finland, but revised forecasts today predict that Jyväskylä will miss the majority, if not all, of the snow that will arrive in the country's south on Saturday. In fact, FMI doesn't predict any snow for Jyväskylä in its current 5 day forecast.

Warm weather continued today. Temperatures this afternoon at Jyväskylä Airport managed to top yesterday's figure. It was 9.4C around 3:30pm. Today was the fifth consecutive day above 5C. The earliest time for such an achievement in the previous 5 years was the 5 day period between April 8 and 12 in 2010. 2009 didn't see such a 5 day period until April 21 to 25.

Tomorrow looks to be the last day above 5C for at least a week and a half. Winds should be a little stronger than normal as well.
