I see there is going to be a build up of moisture/dew point with the NW flow, over the NI, providing good CAPE, along with a jet stream, for Thursday

Another strong wind warning for the Canterbury High Country for the next couple of days, as you say Richard hope it isn't as brutal as last week as the Hurunui needs it like a hole in the head.

Wednesday afternoon looking quite good for Canterbury storms in a few aspects as a small low forms this side of the Alps, especially Chch/north with a gap in cloud cover, DP 9C and chance of an easterly with the dying NW but the upper air is only around -20C so maybe low-moderate risk. This going by the last GFS run, as it's currently updating.

21°C, NW breeze fitful at this stage.
