Thursday, 9 October 2014 Forecasts for Ireland TODAY ... Heavy showers in the south Dublin region and a few moderate showers moving inland from the west coast, with a dry start to the day for many regions in between ... showers from the west will advance and follow the departing low as it moves towards Scotland, allowing winds to return to a west-southwest direction after a brief northerly in parts of Connacht and west Ulster this morning. Rather cool with highs about 13-15 C. Rainfalls today should be 3-7 mm on average and with heavier amounts in some central counties. TONIGHT ... Partly cloudy, a few lingering showers, but also brief clear intervals, chilly with lows 3-5 C. FRIDAY ... Cloudy with sunny breaks, scattered showers, slight risk of thunder inland south. Highs near 14 C. Typical rainfalls 5-10 mm, locally 15 mm. SATURDAY ... Partly cloudy, showers and risk of a thunderstorm, lows near 7C and highs near 14. Rainfalls about 10 mm. Moderate southwest breezes at times, becoming more northerly in the western half of Ireland by late afternoon and evening. SUNDAY ... Intervals of cloud and sun, isolated hail or brief rain showers, more frequent in onshore flows in moderate northerly breezes. Lows near 1 C with scattered ground frost, highs near 13 C. MONDAY ... Sunny intervals, slight risk of showers in north, winds backing to northeast 30-50 km/hr, could result in isolated hail showers over higher parts of southeast. Lows near 2 C with scattered frost, then highs near 13 C. TUESDAY to THURSDAY will see a warming trend, with a warmer and drier interval developing after a day or two of frontal cloud and west coast drizzle in southeast to southerly breezes. Highs about 15 C mid-week could reach 18-20 later in the week if the projected central Atlantic low moves far enough north and high pressure remains nearby over western Europe. The details for Britain are somewhat similar but around Monday-Tuesday a rainfall producing low that is expected to miss Ireland will emerge from the Biscay region into the Channel and move into the North Sea, bringing 25-30 mm rainfalls to much of southern and eastern England. Once that system has departed, the warmer spell could begin in Britain and later in the week, rain is even less likely there with the high closer at hand. North America is seeing some fairly typical October weather in most regions, although it remains quite warm in the west. Remnants of the typhoon which hit Tokyo earlier in the week have now entered the Gulf of Alaska as a deep (950mb) low heading northeast. This will pump a lot of moisture into western Canada over the coming four or five days but most of the actual rainfall will be north of Vancouver. Fog remains quite widespread in valleys in western interior regions and near the coast too. My local weather on Wednesday remained fairly warm, but with a lot more cloud and fog the high only reached 18 C, with brief sunshine near the end of the day. -- Peter for IWO
