Wales - Regional Weather Discussion

[mikeocarroll]

A few bits of wintriness in the showers here too - the tops of the hill have a dusting of white - the snowline was about 400m first thing this morning but is now about 550m, temps rising rapidly.

[DeepSnow]

Had some very heavy hail showers thismorning, temp now dropped to 4.4C

[J10]

Looking at the rainfall from NMM and it is not looking that good to be honest,

NAE

Over an inch widely, but should clear away quite quickly by tomorrow afternoon.

[Bobby]

Local flooding looks likely tomorrow, I expect we'll get a good 2+ inches of rain here in the valleys.

A spell of wet and very windy weather will affect Wales during Tuesday morning. The public should be aware of the possibility of disruption due to heavy rain, accompanied by strong winds, leading to localised flooding.

Local flooding looks likely tomorrow, I expect we'll get a good 2+ inches of rain here in the valleys.

I hope you are wrong, but I fear you may be right. How wet is the ground up there, as this may effect runoff etc.

[DeepSnow]

Though only a small patch of wales, im just inside/on the border of the amber warning! Glad Im not in school tomorrow so can stay indoors all day! Hope there isn't too much flooding, lucky for me I live on a slight hill so never get flooding, stay safe those who are unlucky enough though!

Colder out there today with some showers mostly of rain and hail here on low ground, looking at the radar showers will continue over the next couple of hours gradually losing any wintry component as the flow turns to the SW:

Overnight and into tomorrow we will see that strong low pressure system move in off the atlantic tracking across northern parts of the UK:

Strong south westerly winds right across Wales:

Gusts of 60mph seem likely over SW & W coastal areas of Wales.

One very important thing to point out here is the amount of rain that will fall...theres going to be allot across Wales as shown on the NAE precipitation charts below:

Yn wir, mae'n edrych yn wlyb iawn 'fory, bydd 'na lifogydd lleol bron yn sicr i chi, wrth ystyried bod y tir i gyd yn wlyb domen yn barod, a bydd unrhyw law yn llifo'n syth i mewn i'r afonydd, ar nodyn mwy positif braf yw gweld yr haul heddiw er yn oer.

True, it does look very wet tomorrow, there will no doubt be local flooding, almost a dead cert, because the ground is saturated already and any extra rain will flow direcly into the water courses, on a more positive note, it's nice seeing the sun today albeit cold.

[nwales]

Was hoping for a dusting of snow today but it's been sunny and cold, missed the showers here. Max temp earlier this afternoon of 3.8c

As the day went on, the showers tended to turn less wintry here as well, there was a longer shower at around 4pm, largely rain with only a very small amount of sleet.

It looks very wet tomorrow, and the ground is now sodden after the heavy showers today, One thing to consider Re the NAE rainfall charts is that rain is for 6hrs despite updating every 3 hrs, Not wishing to minimize the risk of heavy rain tomorrow though,

[TonyH]

Dodged the showers here today, a mostly dry and bright day. The system tonight and first thing tomorrow does get through quickly, perhaps some 6-8 hours of heavy rain, which may avert too many flooding problems.

It was nice to see the sun today, and I hope you are right about the rain pushing through very quickly and not causing too much disruption.

[ourson]

There's some heavy precipitation on it's way - http://www.raintoday.co.uk/. Shame it's not faling as snow

No flood warnings yet on the Environment Agency wesbite - http://www.environment-agency.gov.uk/homeandleisure/floods/

Not my prefered weather, but at least it's more interesting than mild mild mild mild .........

Hoping for some cold stuff before too long

[Cymro]

It is tipping it down here atm! Has been for the past hour.

[Blackjack]

I got my first proper weather station for Xmas so i'm looking forward to this ppt so i can try it out the rain sensor

As soon as i get my aerial pole i can get the wind sensor functional

[mikeocarroll]

Rain started here about an hour ago, moderately heavy at the moment. Pressure is falling at about 1.5mb/hour. No wind to speak of yet.

Same here. Hoping for a deluge!

[mikeocarroll]

Aberdaron & Capel Curig reporting 55mph gusts, not unusual for either of those stations, but signs that the wind is increasing.

[Herefordweather]

Wind has certainly picked up here with light rain.

[Cymro]

Very stormy and windy out - and an absolute deluge of rain atm! - flashes of lightening also.

Really is pouring down in Hereford at the moment with gusty winds.

[Cymro]

Well the wind has kept me up most of the night, next doors shed door couldn't have been shut correctly as it's been ripped off!!!! Also very heavy rain.

[Cymro]

Also highest gust so far has come from Wales - Aberdaron at 93mph! definetly very stormy out there.

[welshwizard]

hi guys havnt slept hardly anything through the night,i didnt expect the winds to be this strong,in fact iv been out a few times looking around the house,when is this going to drop? nice up this mountain but not nice when this wind is about.

[benb]

Really wild out this way today- a very loud night with very powerful squalls from the early hours, a bit of thunder and lightening, too, which I thought I may have dreamt, but having read Cymro's post, looks like it was real!

Pembroke wave bouy is reading 24ft- which is massive (once or twice a year occurrence)- and can hear the sea from the house, half a mile away. Will be looking for a sheltered surf later...

According to BBC, A477 at Red Roses blocked due to fallen power cables and tree...

Not had a really strong gust for an hour or so, so perhaps the worst has come through here.
