[geoffw]

this is a thread to discuss wednesdays potential nasty storm - weatheronline have mentioned gusts over 90mph. Please discuss here.

yep, definately looks nastier than this weekends storm. batten down the hatches.

plus more heavy persistent heavy rain forecast.

Not sure if this is going to be bigger than what we have had in the last couple of weeks, but still one to watch along with all the current Atlantic activity.

Keep an eye on the posts in this thread as it may get merged with other relevant ones as we get closer. :winky:

For my region, it looks similar to what I experienced lastnight, but for others, it does appear

quite a significant storm. Looking at the above chart, I'm pleased that I don't live in Ireland

[geoffw]

well if you ask me this system looks far more like a storm rather than a normal atlantic depression!

Hi all-

Global model output suggests this front on a convergent trough with a

pre-frontal low-level jet (~30 m/s) will form into a sharp ana-cold

front. Expected is a core/gap morphology with Line Echo Wave Pattern

characteristics. UKMO invent output (presumably processed 1.5 km var)

is predicting such-

There is a risk of localised damaging winds and brief tornadoes.

I would be grateful if reports of damage and unusual AWS readings

could be amended here. It is important that AWS users switch to high

frequency logging. 5 min logging is insufficient to record the frontal

passage.

Time frame is 18Z 24th to 06Z 25th all of England and Wales as the

front progresses eastwards,

thanks,

David

Morning Waghorn and welcome to Netweather!

You'll find we already have a storm report section and hopefully people can take advantage of the thread here to post reports and extreme/unusual data: netweather.tv

GFS has backed it off a little bit now, but if you look in the convective outlook at the post I made earlier, you will see there are indications for some strong convective gusts and more possible funnels and maybe a tornado.

Ah cheers! Thanks for tidying up after me,

No probs! It gets quite busy in the forum around big weather events and it might be that a couple of different threads are combined as the time approaches, to keep the topic in one location. Keep an eye out and we will try and guide you to where the current, up to date discussion is.

Hi all-

Global model output suggests this front on a convergent trough with a

pre-frontal low-level jet (~30 m/s) will form into a sharp ana-cold

front. Expected is a core/gap morphology with Line Echo Wave Pattern

characteristics.

Radar suggest that would appear to be what is happening now over the Irish Sea. I was just going to post about this but you'd already predicted it, nice.

Here is my wind map for Wednesday showing gusts,

Already 48mph gusts here and northern Wales 78mph gusts.

[Sugar79]

well the wind is really starting to pick up here now and the pressure is falling, down to 998mb at the mo

[Cookie]

gusting 46 mph here

[Zenarcher]

Gusting 48mph here.

[sunny scunny]

Average wind speed is around 30mph here, with the strongest gust at 44mph.

[hobbielancie]

Windy here now but the Squall is miles away yet from us in North Norfolk. Going to be a interesting event.

[Marcus_surfer]

very strange weather here, very strong winds earlier, gusts up to 60mph, then the heavy rain came and winds eased off, now around 10-15mph gusts at the most.

[Roger J Smith]

The squall line in central England at the moment is better discussed in the other thread (convective outlook) where people are following it closely.

As to the winds from the low approaching Scotland tomorrow, it looks like Donegal and parts of Mayo, and then the Western Isles will both see peak gusts near 90 mph from this, and possibly even higher. It will be progressively less intense for the rest of Ireland as the gradient further south is much less extreme. Southwest Scotland (mainland) may also see gusts to near 80 mph.

[Zenarcher]

I'm shocked to see no warnings out from metoffice gusting to 62mph here.

[Zenarcher]

Tiree recording gusts of 70mph.

[glasgow-guy]

wind beginning to pick up here in Lanarkshire again 30mph winds and no met office warnings very strange indeed

[Cookie]

77.1mph here today

[Zenarcher]

Highest gust for me so far is 70mph. Its calmed down a bit gone to 50-60mph because the low is moving over us but by 9am winds should pick up again.

Wind gusts are so far not too high although i expect that to change later.

A few showers this morning, i love how the shower clouds are being "lit" up by the low sun, makes outside look "wintry" so to speak.

[Methuselah]

It's blowing a bit here, now...I can even see SNOW in the sky!!!
