It's not going to be such a Beautiful Day for the second U2 concert at Auckland's Mt Smart stadium tonight with a "good chance of a shower or two drifting over".
Despite the muggy 22C forecast in Auckland today, MetService meteorologist Peter Little says concertgoers should take a jacket with them, but also reassured it won't be a downpour.
"For today it's going to be bits and pieces of rain. Certainly one of the main things for Auckland is it's going to be very humid," Little said.
"Muggy northeasterlies with a lot of cloud. There will be some bright patches during the afternoon but there still will be one or two showers about. So quite drizzly. "Take a jacket to U2, but it doesn't look like it will be a particularly wet time. It will just be fleeting, any showers that come across."
Yet, Little said this afternoon was the best time for North Islanders to get outside because it will only get worse on Sunday.
"Tomorrow unfortunately things do start to deteriorate for the North Island. Pretty much everywhere we're expecting rain," Little said.
"Places that are sheltered from northerly flows, like Gisborne, Hawke's Bay, the Wairapa, Whanganui and Manawatu. They will have less rain than places further north and west, but we're still expecting very cloudy conditions and there'll still be some rain for those areas so it's really an indoor day.
"People who have plans for the weekend, today for the North Island is definitely looking like the best day to get out and about and enjoy the outdoors."
Another weather phenomenon people in the North Island are currently experiencing is especially radiant and colourful sunsets created by smoke from the New South Wales bush fires.
"Unfortunately in NSW these wildfires burning and yesterday we could see large plumes of smoke from satellite imagery pushing into the Tasman," Little said.
"There's northwesterly winds aloft and they've been an ideal direction to bring that smoke across to New Zealand.
"Unfortunately it's going to be quite cloudy in many places but areas that do have clear skies for tonight's sunset may notice it a bit more colourful than normal. The sun can refract off more particles."
Elsewhere around the country the conditions are going to be quite stormy with a raft of severe weather warnings and watches in force.
"Unfortunately it's looking pretty rough in many parts of the country. "A lot more rain to come in the already saturated parts of the South Island. We're also expecting strong winds in many parts of the country as well over the next couple of days.
"Wind watches are in force basically from the Bay of Plenty, Gisborne, South Taranaki, Whanganui, Taihape, parts of Hawke's Bay.
"We have a heavy rain watch for many parts of the North Island, more from Sunday into Monday, and that includes Auckland, Waikato, Taupo.
"So once the front moves northward we are expecting the weather will deteriorate. But that's not really until tomorrow."
Along with the storms will be high humidity and temperatures across the entire east coast of the country.
"We've got this persistent northerly flow and that's brought very warm air down from up towards the tropics and partly that's why we've had this very good potential for heavy rain for the South Island and for other areas as the front moves north," Little said.
"It's being fed by a lot of this moist warm air and that's also led to the very humid conditions and also for eastern areas some very high temperatures in the afternoon."
Nearly all major cities across the country are over 20C today, with Napier reaching 28C and Christchurch hitting 27C.
