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.

A last spell of summer heat for some parts?

Last week brought a wide variety of weather for the UK. The week began on very quiet note, with high pressure bringing chilly starts and then long sunny days of warm sunshine. As the week progressed though, an unseasonably deep area of low pressure moved in from the Atlantic to bring very wet and windy conditions across many parts of the UK, along with a distinctly cooler feel. Gales affected many parts of England and Wales through Saturday.

After a drier and less windy Sunday, this coming week offers a reversal of the last. Early in the week, We can expect a further rain-bearing system to bring some rather wet weather for many places, but as the week progresses, warm air is expected to drift in from the near continent to affect southern and central parts of the UK, along with a few thundery showers, giving a summery feel. Further north and west though, the remnants of Atlantic weather systems will likely bring a fresher feel with the threat of showers.

Beyond next week, and into the last days of the meteorological summer, it looks like the warm conditions across southern and central areas will be shunted back into the continent by westerly winds that will bring Atlantic weather systems towards our shores. The most unsettled conditions will likely be across northwestern areas, but some more prolonged dry weather may well still be in store for southern regions into the last days of summer. Read on to find out the details...

Dé Luain 22 Lúnasa—Dé Domhnaigh 28 Lúnasa
Hot and humid in the south, fresher in the north.

Monday will get off to a damp start for much of the UK, with a particularly humid feel across southern parts of England and Wales. Through the day though, skies will brighten for Northern Ireland and also eastern parts of England and Scotland. Wales, western Scotland and western districts of England will likely stay rather cloudy and muggy though, with some further albeit patchy rain at times.

Overnight into Tuesday, warm air will start to drift in from the near continent across the southern half of the UK. Through Tuesday daytime, this warm air will prevent an Atlantic front from making any further significant progress east, as it brings rain to Northern Ireland, northern England, southern Scotland and some of the western fringes of Wales and southwest England. By contrast, parts of southeast England and the Midlands will experience some fine and warm conditions.

A similar theme will prevail on Thursday with a good deal of fine, dry but hot and humid conditions across the southeastern half of the UK, but a stalled Atlantic weather front may bring some outbreaks of rain to areas further to the northwest.

Thursday will most likely bring the onset of some thundery showers across the southern quadrant of the UK to bring a rather hot and humid feel. To the north and west, further cooler and damper conditions are expected, again in association with a waving Atlantic front that will be stalled from moving further east by the feed of warm air pushing up from France across the eastern side of the UK. Through Friday and into the weekend, at this stage it looks like an Atlantic low will gradually bring fresher and showery conditions to northwestern parts, with less warm and generally bright weather in store for south England and Wales as the hot and humid continental air recedes away to the east.

Dé Luain 29 Lúnasa—Dé Domhnaigh 4 Meán Fómhair
Summer making an early exit from the northwest.

As we head into the last few days of the meteorological summer, the most likely synoptic set up is that the jet stream will be suitably positioned high in the skies across the mid-Atlantic to push a low pressure system towards the northwestern half of the UK. As a result, it is likely that Scotland, Northern Ireland and northern England will experience a breezy end to the summer with outbreaks of rain at times, with temperatures around perhaps a little below where we'd normally expect them to be in late August.

Further to the south, although some showery and breezy spells can be expected at times, it is likely that the weather across Wales and the southern half of England will often be fine and dry, with some warm days at times.

Similar conditions are forecast for the first few days of the meteorological autumn.

Dé Luain 5 Meán Fómhair—Dé Domhnaigh 18 Meán Fómhair
Fairly typical early autumn weather.

As we move into the first full week of the meteorological autumn, all the forecasting tools and techniques at our disposal point towards a fairly unsurprising meteorological set up for the time of year. At time of writing, the most likely scenario is that the jet stream will continue to push Atlantic low pressure systems towards the UK at times throughout this period, with the wettest and windiest conditions most frequent in the northwest, and the rest of any drier, brighter and warmer interludes reserved for southern parts of the UK.

An tseachtain seo chugainn

Next week's issue will take us into the latter part of September. Will there be a sign of any potent autumnal Atlantic weather systems heading our way? As always, we'll be keeping a close eye on any developments in the forecast here at the BBC Weather Centre.

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.

Heavy showers for some, otherwise dry with some warm sunshine.
Today

Heavy and locally thundery rain will affect northern England at first. Further showers, heavy at times, will affect parts of Scotland, England and Wales, however most parts should see some warm sunny intervals, whilst some western parts stay mostly dry.

Tonight

Showers will ease through the evening to give a dry night with clear spells, allowing some mist and fog patches to form. Fresher compared to recent nights for many areas.

Monday

Early mist and fog will clear to give a fine day with some warm sunshine for many. Cloud will thicken in the west with some rain across north-west Scotland later.

Outlook for Tuesday to Thursday

Largely fine and warm on Tuesday before cloud and rain slowly spreads south-eastwards through Wednesday. Breezy with showers behind this across the north, but drier for most during Thursday.
