Intense Tasman Low - Nov 24-26
Thought I will make a thread for next week's low.

Looks like 30mm for Auckland and heavy totals for central north island. . Flood risk .

EC's 18Z run upgrading around Auckland to 40 to 60mm for the thread which is looking similar to the UK 12Z run.

Every run seems to have this low more and more further north. Not expecting more than about 10mm here in Christchurch.

Re: Intense Tasman Low - Nov 24-26
Rainfall from the warm front in the next 24hours for the Auckland region according to 12Z EU.
Some cooling upper air tomorrow means a few squally thunderstorms could develop over the North Island given the high dewpoints.
GFS shows a cold front crossing from the middle of the day.

Upper polar low over the Antarctic shelf launching the injection streamer into the west side of the Tasman low with a warmer moist jet to the east side.

Re: Intense Tasman Low - Nov 24-26
We will have a cool maximum temperature here today, currently 16C, overcast light rain
Humid weather here tomorrow with cool upper levels, see what weather action can happen.

Re: Intense Tasman Low - Nov 24-26
Why did I just hear on the radio them saying a storm is coming with possible power cuts and the most rain in one go since April 2017??? Seems pretty irresponsible

Re: Intense Tasman Low - Nov 24-26
Probably referring to the metservice tweet and outlook for squally thunderstorms tommorow. I expect localised powercuts and downpours with thunder and Gusty winds at least

Re: Intense Tasman Low - Nov 24-26
Just read the NZ Herald article saying the same thing. “ There was also expected to be up to 25mm of rainfall in one hour which would be the biggest fall since April 2017“.

Yes. it looks as though that you will experiencing a rather stormy period with this low. Some periods of rain which haven't been seen for a while.
Looking forward for the drizzle, here tomorrow.

Re: Intense Tasman Low - Nov 24-26
Wheewy!
EC (usually conservative in its CAPE calculation) is chucking some serious numbers round the Waikato (1700j/kg), although CAPE is terribly fluid
Certainly some moisture laden air coming our way with quite high precipitable water values.
Upper air is fairly cool around -14 to -15 degree region tomorrow afternoon.
Looking forward to some Lightning!

Re: Intense Tasman Low - Nov 24-26
Temperature up to 18C this morning. Only 4mm rain overnight, less than forecast which is disappointing. Fingers crossed for some decent falls today!

Re: Intense Tasman Low - Nov 24-26
the cold front and clearence is coming in fast according to the sat image
interestingly my Air Pollution reading has incresed as the wind has gone more northerly....and I know that salt spray affects it..so it likely a pre cursor warning of a sudden NW change coming
big temperature rise here overnight with that warm front too
28mm here so far in total
now my wettest November on record!, 186mm
