Saturday, 27 December, 2014 Forecasts for Ireland ALERT for wintry showers becoming more widespread later today, and (over the next three or four nights) severe frosts all leading to icy roads at times. TODAY ... Variable cloud with outbreaks of showery rain, hail or snow. The air aloft will be getting colder which may turn more of these over to snow in northern and central counties by afternoon and early evening. Cold with moderate northwest to north winds 40-70 km/hr, turning slightly to northeast at times -- this could bring Irish Sea streamers onto the Wicklow coast if not as far north as Dublin, precipitation in these will likely be rain near sea level, hail or snow higher up. Highs about 5 or 6 C, but temperatures likely to fall to about 2-3 C in heavier wintry showers. TONIGHT ... Wintry showers becoming more isolated then ending, clearing, severe frost and patchy ice fog, drive with extreme caution. Lows -6 to -3 C. SUNDAY ... Persistent freezing fog in some areas, wintry sunshine elsewhere, highs struggling to reach 4 or 5 C for most (7-9 C Atlantic coasts). Persistent ice fog could keep one or two places near 0-2 C. Winds light or calm. MONDAY ... Severe morning frost and fog, lows -7 to -4 C. Somewhat less fog should persist and it will slowly become a bit milder, highs 5-7 C. TUESDAY ... Another sharp frost with local ice fog, lows -5 to -2 C. Then partly cloudy, somewhat milder especially in western counties where highs may reach 9 or 10 C. Still about 6-8 C in east. WEDNESDAY (New Years Eve) and THURSDAY (New Years Day) will be breezy and mild with some rain likely, although perhaps not all that much, with temperatures generally much milder in the 7-10 C range. Another frosty high will develop but it wont be as severe a frost on mornings of 2 and 3 January by the looks of most guidance, about -2 C with days around 7 C. Then we enter a possibly quite volatile and stormy period around the 4th to 7th of January. Storms may have fairly cold air masses entering their circulations and showers from them could be quite mixed. Britain has seen some outbreaks of heavy snow from the departing storm, mainly in the Midlands and inland southeast. From now on the pattern there will become similar to the above with severe frosts and ice fog developing for several nights. Only western Scotland will see much relief from this before New Years Eve as southeast England stays under the cold high pressure area longer. Over North America, Christmas and Boxing Day as we also call it over here have been unseasonably mild in much of the U.S.A., and eastern Canada, closer to normal but somewhat on the mild side in western Canada, but here on the west coast it was a bit below normal with highs near 5 C under cloud. -- Peter for IWO ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
