1300 on Sat 7 May 2016 to 2100 on Sat 7 May 2016

Whilst the majority of places within this warning area will see a dry and very warm Saturday with a good deal of hazy sunshine there is a very low likelihood of isolated intense thunderstorms developing during the afternoon and evening.

Faoi Rabhaidh Aimsire na hOifige Meitéareolaíochta

Tugann BBC Aimsir dhá chineál rabhaidh aimsire eisithe ag an Oifig Meitéareolaíochta: Rabhaidh agus Réamhrabhaidh.

Rabhaidh -eiseofar iad seo nuair a mheasfar go mbeidh drochaimsir ann faoi cheann 24 uair.

Réamhrabhaidh -eiseofar iad seo breis agus 24 uair roimh aimsir dhian.

Tá trí chatagóir teagmhais ann, mar atá, Dearg, Ómrach agus Buí - is é Dearg an ceann is measa.

Bíonn Rabhadh agus Réamhrabhadh den dath céanna chomh trom lena chéile ach táthar á thuar go dtiocfaidh siad ag amanna difriúla. Mar sin, is é an difear idir Rabhadh Dearg agus Réamhrabhadh Dearg ná an t-am is luaithe a thiocfadh leis tarlú.

Nuair a bhíonn rabhadh i bhfeidhm, is féidir faisnéis iomlán a fháil ag Rabhaidh Aimsire na hOifige Meitéareolaíochta

Maidir le Rabhaidh Tuilte

Eisíonn an Ghníomhaireacht Comhshaoil, Scottish Environment Protection Agency agus Natural Resources Wales na rabhaidh tuilte agus cuirtear ar aghaidh chuig Ionad Aimsire BBC iad. Ansin eisíonn muid coimre rabhadh bunaithe ar an eolas is déanaí atá ar fáil. Nuair a eisítear rabhaidh tuilte troma, aibhseofar ar chraoltaí teilifíse iad chomh maith.

Is winter over yet?!

It was another blustery week of weather across the UK with rain, hail, sleet and even snow! Yet, if you were out of the breeze and in the sunshine, it did actually feel a little like spring, and by the end of the week it may actually start to feel like summer (well for some of us)!
Last week our weather was dominated by a northerly pattern which brought a continued spell of below-average temperatures, but this week our weather has more of a southerly and westerly influence and this means that are temperatures will start to creep back up.

Dé Luain 2 Bealtaine—Dé Domhnaigh 8 Bealtaine
Some signs of summer!?

On Monday, the south east will start off on a damp note as rain moves south-eastwards. Behind the rain there will be sunshine and scattered showers but the showers will be mainly focused across the western half of the UK. We'll see sunny spells and some further showers during Tuesday and Wednesday and, as our winds will be westerly, we will see day on day improvement in temperatures. A mainly dry day on Thursday with temperatures approaching the mid-teens in the north and near twenties in the south, although Northern Ireland and the far north west of Scotland will be breezier with patchy rain. Dry and warmer for much of the UK on Friday as our winds start to become southerly. This will draw warmer air from the continent and and while most of the country will see temperatures in the mid-teens, the south may see temperatures closer to twenty Celsius. As we head into next weekend, the southerly influence will mean there is a risk of drawing thundery showers across the southern half of the UK. There is still a lot of model discrepancy as to what will happen across the northern half of the UK, but, at the time of writing, it looks there will be the risk of showers continuing to travel northwards.

Dé Luain 9 Bealtaine—Dé Domhnaigh 15 Bealtaine
Have we finally said farewell to winter?

As we head into the second week of May, our computers models are emerging with a pattern of south or south-easterly wind direction. This can lead to quite a varied weather pattern from unsettled with showers and rain to dry and fine conditions. What this wind direction also indicates is that there will be rather warm conditions in the south at times, with this warmer air sometimes extending northwards across the rest of the UK.

Dé Luain 16 Bealtaine—Dé Domhnaigh 29 Bealtaine
A northwest / southeast split?

Towards the end of May it is no surprise to know at this extended range there is quite a variety of weather patterns emerging from the various computer models. At this stage, the dominant wind direction is expected to be from the west or southwest, which would indicate lower pressure to the north and west of the UK and higher pressure to the south and east of the UK, the latter being where we are most likely to see the driest and at times warmest conditions.

An tseachtain seo chugainn

So will this signal for a divide continue as we head into summer?

Réamhaisnéisiú míosúil
Ní furasta an aimsir a thuar níos faide ná seachtain nó mar sin chun tosaigh, fiú don réamhaisnéiseoir is mó taithí. Déantar samhaltáin uimhriúla casta a fháil ón Oifig Meitéareolaíochta agus ón Lárionad Eorpach do Réamhaisnéisí Aimsire Meánraoin (ECMWF) agus déantar iad a rith a lán uaireanta don mhí (agus don séasúr) atá le theacht. Ar an dóigh sin, cruthaítear pictiúr den dóchúlacht go rachadh cineálacha éagsúla aimsire i bhfeidhm ar an RA.

A warm day with a mix of sunshine and showers. Some Showers may be heavy with a risk of hail and thunder, these most likely over Wales and Central England.
