Possible "Bomb" cyclogenesis - Jan 18-20

[NZstorm]

Are there any charts available that show the winds increasing to 160km gusts at or near ground level. Thanks appreciate any guidance regards to this.

I use the forecast 850mb winds to assess maximum gust potential. Modeled 850mb wind speeds are very high near the front, 80 knots (150km/h).

The warning signs of the strong winds coming are that the clouds are fair motoring.

Gusty ENE here today.
I noticed there was some lightning westward late last night and overnight from a front prior to this system moving across us.

Winds are getting started at Mt Kaukau now (one of the most exposed places in wellington with a weather station)

Metservice a little off with their timings of the arrival of the severe gales, still easterly in Darfield and West Melton at 7.10pm, not really late afternoon anymore which is when they said it would begin, I wonder if the low pressure system has stalled in the last few hours unexpectedly?

Nice sunny evening here but cool for the time of year, only 17C with a light NE.

[Bradley]

Complete non event here!!

[melja]

I wouldn't think 17C is cool for the time of year at near 8pm lol

Cool for the conditions expected from the oncoming front. Should be in the twenties, like yesterday.
Anyway, beefy looking thunderstorms moving onto Westland by the look of the latest radar for the West Coast.

[Richard]

Should be a good light show in another half hour or so with that line nearing the West Coast

[Orion]

Has clouded up again to the west here.

[Richard]

Yes and the wind is really starting to pick up now.

west coast getting plastered with lightning strikes!

[Chris Raine]

At Runanga continuous lightening and thunder since 9.30pm and heavy rain

Your shoat John.

Next year in the USA
Gone back to light NE here, so giving up on this as far as strong 150km winds go, thank goodness.
Today's maximum was only 19.3C, well below the forecasted max of 24C, although it could be reached in Riccarton ??? with 0.7mm from rain this morning.
Interesting to see if there will be thunder chances around tomorrow here from any lightning strikes?

[mikestormchaser]

NW wind has picked up in rolleston. Raining quite hard to
