Storm & Convective Discussion - 04/07/15 Onward - Heat & Plumes

[The PIT]

Missed us well tot he noth Grrrrr.

[Derry O'Brien]

Sorry mate, but I'm in sunnyhunny at the mo, it rained hard for about 3 minutes. 43mm is over an inch and a half. Where are you getting this ob from? If there was 43mm in 3 minutes then I'd be swimming down Greevegate.

 

Came down extremely hard for about 10 minutes.. The garden rain gauge seems to think 43mm.

Yeah just had thunder but the lightning activity is to the north of here.

What lightning maps are you looking at? I'm not picking up any around Leeds.

That's a serious amount of rain in 10 minutes. I think that figure may be a bit off!

Some very pretty cauliflowers blooming west of me now:

NW radar shows a couple of strikes... too miserly to pay for full edition but free one shows them.  Also the blitzortung app shows them.

See what your on about now.. The radar for me has just sprang into action North-East of Leeds.. 

 

Also using http://www.lightningmaps.org/realtime aswell as NW radars.

Sorry to appear dismissive but 43mm in 10 minutes equates to an hourly rate of 6x43 which is about 250mm per hour - it's absolutely impossible. Either your rain gauge is underneath a leaking overflow or it's very definitely miscalibrated. I think you'll see there was about 2mm.

[Methuselah]

That's a serious amount of rain in 10 minutes. I think that figure may be a bit off!

Indeed, Nick - 4.3mm wouldn't be bad, for that space of time?

Lol, divide by 10 and halve.

[Richard Taylor]

Nice structures to the clouds around Aberdeen now. Still bright to sunny, +20.

Not entirely true, Candice: http://wmo.asu.edu/world-greatest-sixty-minute-one-hour-rainfall

Any chance that the cheap rain gauge was collecting water from a larger area then i should have been?

Depends where it's sited...see above.

ah yes i see I feel a bit dumb believing it now!

No worries...I once put a rain-gauge under my shed's guttering!

hahah, going to make sure i put it in a better place for next time the rains back!

Wish i was further north! Looks like some places are up for 2 thunderstroms in a row!

4.3mm would sound much more reasonable. We got 3mm from our section of the line.

And 250mm/hr rain rate is perfectly plausible to record in this country. I've recorded into the hundreds on more than one occasion.

[Derry O'Brien]

4mm would be generous, i also know that 43mm is crazily unlikely.. but I personally think it was a bit more then 4mm! 

Currently trying to see if there are any stations locally other then the Heacham one so I can see what it really was..

[Nick L]

Not entirely true, Candice: http://wmo.asu.edu/world-greatest-sixty-minute-one-hour-rainfall

 

Well that's a different measure to be fair. That's the rainfall that DID fall in one hour. Not the extrapolated rainfall rate from an intense 10 minute burst.

 

The highest 5 minute rainfall total officially recorded in the UK was 32mm, and that equates to 384mm/hr!

As always, Lincolnshire is the place to be?

Yup. This is what flooded my local co-op out for the third time in a year..
