Very Wet and Unsettled
The Long Range weather sees unsettled weather for the rest of December. These will bring periods of wintry showers mixed with drier spells. This week looks particularly wet with over 50mm of rain in some places leading to flooding. Christmas Day looks wet and showery with some showers of sleet and hail. Met Eireann have forecast a cold weekend with lots of wintry showers as Ireland sees the first blast of Winter this season. Temperatures are set to plummet to values of -3c overnight and daytime values will be just 5 or 6c. The showers will be mainly of rain sleet or hail but at levels above 200m snow will fall so if you are driving in hilly terrain be very careful. A few showers of snow may fall at lower levels too these mainly in the Northern half of Ireland. Next week sees more cold wintry weather. In Sligo town most showers of rain or hail but in Collooney and Tubbercurry and Geevagh for example more snow or sleet showers are likely.
Ex Hurricane Gonzalo moves to the Northwest of Ireland on Monday night and into Tuesday. Winds will be 60knots and tides will be 5m off the West coast causing a little coastal flooding. A very unsettled period of weather is now upon us in Ireland. The next 7 to 10 days weather is set to be wet and windy. The temperatures this week are going to be 15 to 18c in any sunshine but after the weekend it will be back at 12 to 14c as much fresher air feeds in bringing showers off the Atlantic. Rainfall in the West and South could be as high as 100mm in this period. In most other places it will be around 40mm so still wetter than normal. Winds will start off from a Southerly source but will move to a Westerly early next week.
Rain and wind have brought over 40mm to parts of Ireland. There is an unsettled cool week ahead with showers or rain every day. Only 11 to 14c
September is going to be a reasonably dry month for Ireland especially in the first half of the month with temperatures around normal at 17 to 20c. After midmonth more unsettled weather tries to push in and this will be most likely in the last week of the month. Overall temperatures will be slightly above average, sunshine will be above average and rainfall will be well below average.
Dublin Heavy Rainstorm but little flooding - why?
August 2nd 2014 saw some really torrential rain in Dublin as over 90mm of rain fell. In normal circumstances this would have resulted in severe flooding. However due to the dry nature of the Summer up to now the rains caused little flooding apart from some road flooding on the M1 and M50. Land saturation did not occur to any great scale and by Monday 4th August it was a case of what rain?
So far this year there has not been any extraordinary weather apart from the stormy tidal Winter and the warmest temperature for the year at 27.7c in Oak Park on 25th July.
