Talk about Spring chaos! On Monday single digit highs were felt across the South Island, today highs in the late teens maybe even 20 degrees are expected.
It’s all to do with airflows – on Monday a high around southern NZ was dredging up a very cold southerly out of the Southern Ocean. Many places had highs between 7 and 9 degrees on Monday.
Now Thursday we have a westerly flow kicking in from Australia and this will warm up further as it crosses over the Southern Alps, pushing southern and eastern temperatures up this afternoon with highs of 16 to 19 degrees forecast and perhaps one or two maybe even breaking 20.
Warmer weather moves into the North Island on Friday before a cool down at night arrives.
