Forecast sounding from GFS for Tahuna, Waikato yesterday. Not enough shear there for a supercell but cb's can get organised for short periods and resemble a supercell.

Looks like there is some tho. I think it got a extra lift/help from the local hills.

Getting some excellent rain in Laingholm, though it’s come with the inevitable power outage.

The country's hot spot today looks to be Napier Airport on 30C and Timaru and Dunedin airports got to 28C.

An overcast dull day for Auckland and showery but the temperature still managing to get to 24C. Grey Lynn 14mm today.

Really threatening clouds over here all evening but nothing came from it apart from some spits

Hopefully better thunder chances tomorrow

Tomorrow I think the daytime heating is the key. Isolated severe hail possible inland NI given the colder upper air there. 500mb chart for midday tomorrow.

The mid level flow (700mb to 500mb) needs to be quite strong for a supercell as that tilts the storm.

Good point about the wind off the Firth of Thames getting orographic lift.

NZ Thunderstorm Soc · Wed 03/03/2021 21:14

Looked there was some activity off the coast near Balclutha late this afternoon. Some strikes.

NZ Thunderstorm Soc · Wed 03/03/2021 23:28

Mainly fine and warm day here with NW winds with the high cloud this morning clearing away to the NE.
28C for today.

Looking at today, low risk for canterbury to me.
High cloud cover today over much of south island. Afternoon convection and convergences may get some heavy showers develop this afternoon from timaru and north as far as chch if heating allows

Cyclone Tracy · Unread post by **Cyclone Tracy** » Thu 04/03/2021 09:06

A few sparks to the NW of Auckland

GraemeWi · Unread post by **GraemeWi** » Thu 04/03/2021 09:18

Fairly frequent thunder out to my west here in Swanson, too murky over the Waitakeres to see anything

darcyplumb · Unread post by **darcyplumb** » Thu 04/03/2021 10:36

Wind convergence firing up some heavy showers on the Canterbury plains, perhaps a little earlier than expected.

Just had a really close lightning strike in Cambridge CBD after 15min of torrential rain.

The weather has remained cool and overcast in Auckland this morning. I see Whenuapai only 18C, probably getting outflow from that storm near Kaipara Harbour. Grey Lynn on 19C. Distant thunder heard here from that north Auckland storm.

GraemeWi · Unread post by **GraemeWi** » Thu 04/03/2021 11:58

Sounds like near constant thunder off to my north, the Kaipara system must be quite active. Currently working so can't watch it :-/

Could be some action in the next couple hours. Might be our only hope for today...
