I’ll take the entire station into the shop for an inspection.
Sounded like it might have been (a positive strike). Curious as to the size of the electric fence wire that got vaporized. I'm guessing 12 gauge high tensile?

Re the 433 MHz link from the anemometer no longer working, just before a lightning strike the action of developing leaders can generate huge electrostatic fields in the vicinity. These electrostatic fields are what causes the air to ionize and generate the leaders. Aerials are very good at converting electrostatic fields (yes I know the case will attenuate it) into electrical signals. From a technicians perspective, the receiver (designed to receive down into low microvolts) is likely damaged & deaf. Whereas it's transmitter may still be ok (working in volts). Try bringing the two very close together and see if you can get them to pair again. If it's just deaf receive, it might be simple to repair if it has a front end device that is easy to swap.

(I do know a bit about both radio & lightning having been heavily involved in some Telecom NZ research stuff in the late 80's)

The instability weakens as it approaches and currently looking like only isolated storms over the NI Monday. That means the odds of us getting one are low. Will update tomorrow.

Might happen. One thing about weather forecasting is you never have all the information so there is always an element of guess work.

I notice on EU a pool of moist warm air over Christchurch tomorrow midday, just ahead of the southerly change. May get a storm out of it.

Interesting numbers on GFS this morning... low level snow showers again (below 100-200m) on tuesday morning in Canterbury. Twice in one week after the equinox... surely not!

I agree on both of these - an interesting 24 hours ahead for Canterbury again.

I know spring is a changeable season.. but 25deg... then potential near sea level snow showers the next day or 2... I can't remember that much of a contrast in such a short space of time. Quite insane!!

Another impressive streamer lining up on the 6pm water vapour image from above the Antarctic continent and high intensity lightning still occurring east of the frontal boundary in the Tasman NW of the NI. Interesting 48 hours ahead :smile:

NIWA tweeted 25.6 I think for Chch at their much maligned Riccarton station. I buy it, it was bloody warm out there, and Jeff's is a good setup to corroborate it

I agree in built up urban areas the temperatures can get higher than whats recorded at airports which tend to be rural areas.
