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

Change of month, change of weather!

This may only be conjecture, but it seems that that lately a change in the calendar month is often accompanied by a change in the type of weather. We saw it from July into August, where we went from warm and settled to cool and wet. We then switched back the other way into September, which has in fact been notably dry. Now, as we hurtle towards October, we are again looking at a switch to unsettled weather. The transition will be gradual; each new weather front that arrives from the Atlantic will have better success than its predecessor with nudging away the stubborn area of high pressure that has helped to keep September generally settled. By the first full week of October though, the models are currently signalling increased chances of rain and wind. Interestingly this signal has been suggested since October started falling within the scope of this Monthly Outlook, and now we can put a little more detail on at least the first few days of the month.

A few fine days, then...

The week starts generally on a somewhat summery note, following a weekend where temperatures were rather above average for the end of September. But rather than continuing the settled theme following a few fine days, there will in fact be a risk of areas of showery rain moving northwards, with isolated heavy showers and possible thunderstorms following on later. On Tuesday, cloudier, wet and breezy weather in the northwest will push eastward across Northern Ireland and much of Scotland. At the same time, the front responsible will weaken, leaving much of Wales and England with a fine day. The weakened weather front will bring its cloud and patchy rain southwards on Wednesday. Behind it, skies will clear, leading to a cold and frosty night in the north of the UK on Wednesday night. Thursday looks like a decent day for the bulk of the country, with the best of any sunny spells in the southeast. It won't last however; it will turn unsettled and windy from the north and west during Friday and Saturday as a more vigorous front will bring wet and rather windy weather southeastward. For the rest of the weekend, clearer weather will follow the active front, although with locally heavy showers pushing into northwestern parts. For the week as a whole, daytime temperatures will be generally near normal, perhaps warm in the south in any sunshine.

Autumn arrives, finally.

Into the following week, it looks at present as though it will gradually become more unsettled across all the UK. Periods of wet and windy weather can be expected, albeit with drier and brighter periods in between. The warmest, driest part of the country is likely to be the southeast, which will remain closest to the area of higher pressure over Europe. Elsewhere, especially in the wetter, winder spells, daytime temperatures will most likely be on the cooler side, with a risk of local frost and fog developing where clear skies prevail overnight.

Some more rain for the gardens.

Current indications suggest that generally unsettled conditions are likely to affect many areas of the UK during this period, with spells of wet and windy weather continuing. However these are still likely to be interspersed with drier and clearer interludes, which will also bring an increasing risk of overnight frosts and fog patches, especially across northern parts. Daytime temperatures look signalled to remain generally close to the seasonal average.

Will the weather change type again as we move into November?

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.
