Easterlies return over the North

[Willoughby]

Hmm, the 12z model runs favour development of a shallow easterly/se system over Northland by Wednesday with that trough incoming from the SW guiding into a sub-tropical disturbance bearing down. Could get nasty due to moisture content and could then possibly track in and around the East Cape...
Warm advective snow may be a possibility if the cold air undercuts it there?

Interesting times..

Oh
Will that mean thunderstorms over Christchurch?

LAPS looks very keen to hold onto this low.. could send persistent heavy rain through Eastland.. GFS 12z gives the Waikato a solid fall..

The two northward and southward depressions are starting to mix above now.. this one developing could really pounce up behind us even though cyclogenesis is relatively low at the moment in the Tasman due to increasing pressures coming off the bight.

Well we can only dream now about easterlies as the winds are now Rising from the SW

West southwesterlies rising nicely tonight, to *gale force* at times over the upper north
