An active week of weather

June 18, 2012

Like last week, the weather this week will be unsettled at times. “Unlike last week, though, we’re looking at a generally warmer next few days, with the air coming from the Tasman Sea instead of the Southern Ocean,” commented Media and Communications meteorologist Daniel Corbett. “And in this case, the warmer air is organised into lines of showers and thunderstorms, with the first of these lines crossing much of New Zealand today.”

Corbett went on to say that, “Today, and possibly again on Wednesday, shower and thunderstorm activity over parts of the North Island’s northern and western coasts brings with it the risk of a few small tornadoes.”

For most of this week, the Tasman Sea is expected to be a breeding ground for lows and fronts. From time to time, thundery rain and squally winds are likely to affect the north and west of both islands. Temperatures are generally expected to be higher than last week, with daytime highs over the east of the North Island reaching the mid-teens and overnight minimums in most places perhaps five degrees warmer than last week’s chilly nights.

“Today is one of those days that people in northern and western areas will want to keep an eye on the weather as the active storm system moves through, ” said Corbett.
