Typically it pours down at 3pm on a day I didn't take my rain jacket :(
Almost 4mm from that shower, looks like some more to follow. Rather high dew points today.

Not sure if it was the same one but i saw that as i left auckland this afternoon. I caught the edge of it just out of Manukau.
Between Mercer and Huntly it was rather tropical rain as well. Then it moved southish and has just hit here not long after i got to the olds house.

Looks like Hamilton is getting some rain around now, at around 7.00 am it was overcast then had a fine break for about 4 hours now overcast and looks like it is threatening to rain.
Fractus clouds in the picture. It may look like the cloud is descending its not infact it is going the other way.
If you look at the lightning tracker it seems the low is very active in the lightning department.

What the on earth are MS on I would like to know :rolleyes: I would atleast expect to see a moderate risk up for tomorrow afternoon/evening for thunderstorms.
Everything there suggests it i would think apart from the timing but even that shouldnt be a problem, onshore NE winds before hand no NW.
Wooah there goes the Globemaster just now, climbing in altitude right above me what a roar just now :lol: :smile: .
Should be some brief rain later on from the north.
Cheers

MetService have a moderate risk of weak tornadoes for NE coastal areas and the BoP tonight and tomorrow morn in this mornings Severe Convection/ Thunderstorm Outlook.

They also expect NE winds around the Gulf, Waitemata and Manukua harbours rising to 55 km/h, gusting 75 km/h, this evening ... then same again from SW on Saturday evening.

Mean NE winds at 1pm were 37 km/h at Bean Rock, 32 km/h at Tiritiri Is. and 52 km/h in the Colville Channel.

Could be an interesting night ... might even get some waterspouts out here ... :-s

Judging by the rain radar, doesn't look like much coming...metservice not even expecting much instability with the front either, surprisingly. Thankfully 15mm fell here yesterday afternoon (max 10mm in 1 hour) if the front is a fizzer.

Yes, that is a very active strom.. looks like on its current path it will slide just SW of hamilton :(

What are the chances of it fireing up even more when it hits warmer land? or would the land be too cold by then to help convective activity?
