big upper level lightning this morning over toward cambridge ways, heard the rumbles slightly but constant lightning from 6am for around 30mins fanning out into the clear morning sky.

Sudden change from mild and dry to cold and windy in Akaroa about 3.30pm, with showers coming in with the change. (felt like a bit of hail initially in big raindrops) Wind gusts up to gale force.

We've just had a tiny hail/kind of snow shower come over in Hornby. The radar shows that its isolated. How strange.

Yes, around 100mm SW of Chch, which is about twice that area's April normal, but much dryer to the NE.

Meanwhile in the SW of the North Island, Palmerston North Aero's 252mm was more than 4 times its normal (although only 152mm about 6 km further south near Massey Uni).
Hawera, Wanganui and Paraparaumu also recieved more than 3 times their April normals.
