Aucklanders are waking up to a chilly morning, with a temperature of 11.5 deg C, feeling like "three layers of clothing", recorded just before 8.30am.
It will be best to hold the laundry off, as showers expected this morning are due to turn into rain by this afternoon.
The MetService said that rain may become heavy at times and there is also a possibility of thunderstorms and strong northwesterly gusts.
A temperature high of 16 deg C and an overnight low of 9 deg C is forecast in the City of Sails.The rain comes after a horrendous weekend of wild weather for parts of Auckland, particularly in and around East Tāmaki, Papatoetoe and Otara.
A tornado ripped through parts of South Auckland on Saturday - so strong that it lifted roofs off, tore through business buildings and sent trampolines flying.
It also ripped up trees and fences; and even sent a shed flying into an ambulance where a pregnant woman was in labour in Otara.
The woman's baby boy still did not have a name as of yesterday, but the couple were thinking of the moniker "Storm" as a fitting tribute to his entry into the world.
