The potential for severe thunderstorms lingers today & some places might approach warning criteria for rain.
There's an easing trend as we head into Friday but there's still risk of thunderstorms.
There is a moderate risk of these thunderstorms becoming severe, producing localised downpours with intensities of 25 to 35 mm/h, damaging wind gusts in excess of 110 km/h and the chance of a localised damaging tornado, MetService said.

Rainfall of this intensity can cause surface and/or flash flooding, especially in low-lying areas such as streams, rivers or narrow valleys and may also lead to slips.
Driving conditions will also be hazardous with surface flooding and poor visibility in heavy rain.
Wind gusts of this strength, and damaging tornadoes can cause structural damage, including trees and power lines, and may also make driving hazardous.
A heavy rain watch is also in place for the ranges of Bay of Plenty, east of WhakatÄne and the Tongariro National Park until 5pm.
Friday's forecast is for a few showers with mostly fine weather over the weekend.
Severe Thunderstorm watch Updated for Bay of Plenty. Now valid until 6pm today. Thunderstorms could become potentially severe between 9am and 4pm today.
