Sunday, 24 August, 2014 Forecasts for Ireland TODAY ... Rain will gradually spread further east but may not arrive in north Leinster or east Ulster until afternoon (these regions have started quite cold, the temperature at 0600h was only 2 C at Markree, Sligo -- this chill wont be fully dissipated until afternoon). Some heavier bursts with slight risk of a thunderstorm in central to southeast counties mid-day, 10-15 mm potential, with moderate southeast winds developing, some gusts to 70 km/hr, and highs about 16 C, except for west Munster where 18 C is possible late afternoon as a somewhat milder air mass pushes in from the south. TONIGHT ... A second and possibly heavier band of rain will develop and move into Munster, reaching south Leinster by dawn. This will bring 10 mm overnight and more during the day on Monday. Further north, misty with drizzle or occasional light rain. Lows 8-10 C north, 10-13 C south. MONDAY ... With a track along the south coast, the second disturbance will turn winds back to the east for most regions, except possibly along the Waterford and Wexford coasts where it could stay southerly for a time. Heavy rain will spread through Munster into south Leinster. 15-20 mm further accumulations are likely there. For most of Connacht, Ulster and north Leinster, rain will be intermittent and not as heavy except for some isolated thundery showers, and amounts will be generally 5-10 mm. Highs will vary from about 14 C in the north to 18 C near the south coast. TUESDAY ... Rain gradually ending through the early morning, just a few outbreaks of drizzle near south coast later in the day, variable cloud with some sunny breaks and northeasterly breezes during the mid-day and afternoon hours, morning lows 9-11 C and afternoon highs 15-17 C. WEDNESDAY-THURSDAY ... Further rain is likely with a rather warm, humid feel as highs reach 19 or 20 C in some places. Rainfalls of about 10 mm a day seem likely, isolated heavier amounts south-central counties. FRIDAY could bring a break in the unsettled weather, and SATURDAY is somewhat uncertain but chances of rain will gradually increase with the approach of a slow-moving system timed for Saturday night into Sunday morning. This could drop some rather heavy rainfalls if it develops as shown on early guidance. However, this is not the developing tropical storm near the Bahamas, that may not arrive at all but seems likely to be absorbed into a frontal system over the central Atlantic around the first two days of September. Any rain from this would arrive 3-4 September. Will update for Britain and North America tomorrow, earlier comments seem to remain valid ... meanwhile, my local weather has returned to very warm, sunny conditions with the high close to 27 C. -- Peter for IWO
