Monday, 21 October, 2013 Forecasts for Ireland TODAY ... A band of moderate to heavy rain will reach a Dublin-Galway line around 0800-0900h and will then continue to drift further north, with any morning sunshine in Ulster fading behind the advancing cloud by mid-day. Once this band moves north, skies will become partly cloudy but further showers or outbreaks of rain can be expected. Highs 14-16 C in the south and about 12 C north where winds will be mostly from an easterly direction until late afternoon, for other regions, winds southeast veering to southwest at about 20-40 km/hr. Further rainfalls 5-15 mm except 15-25 mm in some central to inland southeast counties during the morning -- the amounts with the rainfall band may diminish in Ulster. TONIGHT ... Mostly cloudy, fog patches, showers and very mild, lows 11-14 C. TUESDAY ... Further bursts of heavy rain with slight risk of thunder, and very mild, with highs around 15-16 C. Rainfall potential 15-30 mm. A second band of heavy rain will approach the northwest by evening. WEDNESDAY ... Showers, still heavy in Leinster and east Ulster during the morning, otherwise more isolated with some sunny intervals developing, not quite as mild. Lows 7-9 C and highs 11-15 C coolest in Connacht and west Ulster. Further rainfalls of about 5-10 mm east mainly. Fresh southwest to west winds developing 35-55 km/hr with some higher gusts near west coast. THURSDAY ... Some sunshine to start, increasing cloud, morning lows 4-8 C for most, 10 C south coast, highs 12-16 C. Rain may arrive in west Munster before evening, then will spread to other regions overnight. FRIDAY ... Rain will be heavy at times and possibly thundery in places, with a cool east wind for Ulster until late in the day (highs there near 10 C) but otherwise another warm and muggy day will develop in the south and then east-central counties, highs 14-17 C. Winds becoming southerly 30-50 km/hr. Parts of Connacht and west Ulster may remain closer to 10-12 C in northeast backing to northwest winds as low pressure tracks through west-central counties. NEXT WEEKEND OUTLOOK ... Rain should begin to ease Saturday morning and there could be some brighter spells by afternoon with highs 12-14 C, fresh westerly breezes developing, then Sunday will be a partly to mostly cloudy day with a few showers in fresh backing southwesterly winds, highs 12-14 C. Monday could see stronger winds (GFS model has very strong winds, other guidance less intense). FURTHER OUTLOOK ... It seems likely that the last few days of the month will be very mild again but it could turn windy or even stormy around the start of November. Highs may be into the mid-teens at times. Forecasts for Britain TODAY .... Rain, heavy at times, moving slowly north through south Wales and the Midlands, showers continuing across the south but with some brighter intervals. Further north, the day will start bright and this band of rainfall will arrive by afternoon in northern England and by evening or overnight in most of Scotland. Rainfalls of 15-30 mm and highs 14-17 C. In general, the outlook from Tuesday would be similar to Ireland with a slight lag time for each system mentioned to arrive over Britain (6 hours on average). There could be some locally heavy or flooding rainfalls by Tuesday in south central counties of England. Forecasts for North America Showers or periods of rain across parts of the inland northeast and Great Lakes, turning colder, with highs near the coast about 17-20 C but falling from 15 to about 10 C inland, 8-10 C through the Midwest and 5-8 C northwest of Great Lakes and into eastern prairies. Dry and seasonable further south trending to very warm and sunny in the southwest and inland western U.S., and at higher elevations in western Canada but fog trapped near coasts and in some valleys. My local weather was like that on Sunday, cloud stayed locked in below 500m and the temperature was near 10-12 C so we drove up a local ski hill (Mount Seymour) to find warm sunshine and readings near 20 C. Instead of the usual view of the city and nearby Fraser valley, it was just a flat blanket of white cloud with just the higher peaks in Washington state visible in the distance.
