Monday, 26 January, 2015 Forecasts for Ireland TODAY ... Windy and slightly colder with passing showers, highs 7-9 C. Some of the showers may be sleety on high ground in north. However, also some sunny intervals. Westerly winds gusting to about 80 km/hr in some areas. TONIGHT ... Generally clear across the south, lows 2-4 C. Cloudy further north with light rain at times, lows 4-7 C. Winds light to moderate westerly near some exposed coasts but calm inland. TUESDAY and early WEDNESDAY will be rather mild with strong westerly winds 60-90 km/hr, and periods of rain developing, highs 8-10 C and near 5 C overnight into Wednesday morning except falling to 1-3 C by morning in Connacht as showers become sleety or mix with snow on hills. WEDNESDAY it will turn colder with showers or periods of rain becoming sleety on high ground, eventually some snow accumulations by late in the day on western and northern hills. Blustery with west to northwest winds 60-90 km/hr and temperatures falling during the day to about 4 C, possibly lower in parts of north. THURSDAY will then stay rather cold in west to northwest winds and showers becoming mixed and wintry at times in the north. Lows -1 to +2 C and highs 6-8 C for most, 3-6 C north. Winds W-NW 50-80 km/hr. FRIDAY it will begin to turn even more wintry in higher parts of the north, and much colder in other areas, in strong northerly winds gusting to 90 km/hr, morning lows -2 to +2 C, and highs only 4-6 C. NEXT WEEKEND and early next week, expect some strong northerly winds at times, passing mixed or wintry showers, snow on hills quite likely, and at lower elevations from time to time, as temperatures struggle to reach even 3 or 4 C. Some sharp frosts will develop and there may be icy road conditions at times as well as lying snow. The main feature of this spell will be strong northerly winds reaching 70-100 km/hr at times in exposed areas. When these winds subside early next week, snow may develop from a chain of weak lows moving south in a broad northerly flow. Details will be hard to assess until much closer to the time but it would not surprise me if some 2-5 cm amounts come into play in the outlook by later this week. At the moment there are indications of a brief warmup late Sunday or early Monday to be followed by almost gale force northwest winds and mixed wintry showers as a low dives southeast across Ulster towards southern Britain. For Britain, most of these trends will be similar and when the very cold spell begins, it may be more severe in parts of Scotland. There is some chance that this spell may dig in and be a prolonged wintry period dominating February, but other guidance suggests continued variable conditions with a mixture of cold and milder spells. Meanwhile, the northeast United States is bracing for the impact of a major snowstorm expected to hit Tuesday (Monday in some parts of the mid-Atlantic states). This will bring 3-6 cm amounts near Washington DC, increasing to about 5-10 cm Baltimore and 10-20 cm Philadelphia, then 40-80 (!) cm in New York City, Long Island and much of New England. Airports in the northeast U.S. are likely to be closed down by this storm on Tuesday and a good part of Wednesday during clean-up. The west is much warmer, in fact records are falling in many parts of western Canada and the Pacific Northwest states yesterday and today. My local weather on Sunday was dry and mild with a few glimpses of the sun and a record high of 14 C at YVR (may have been 15 at my place), also a daily record set down at Seattle WA (17 C there). The temperature at 1500m around here is near 20 C. This is the expected high in parts of southern Alberta as a strong chinook develops. -- Peter for IWO ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ _________________________ - _________________________
