More sub-tropical rain coming in July

If you’re waiting for “real winter” to arrive you may be waiting some time – with forecasting two more lows with sub-tropical rain in the first half of July – with potentially another Tasman Sea low in the middle of the month too (although too far out to lock in).

Long range reliable data shows two lows in the first 10 days of July.

Low number one will affect the upper North Island with isolated heavy downpours and warmer winds this Sunday and Monday (July 3 and 4).

Low number two looks larger and may affect more of the country with once again mild air from the sub-tropics, or near it, and isolated heavy downpours.  This is expected July 9th and may be more of a nationwide low.

What about the cold snaps?
There’s the chance of a nationwide colder southerly flow around July 7 and 8 (as a high rolls in) and then again in the middle of the month – but both look short-lived.
