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

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! :rofl:

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.

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.

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.

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.

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.
