Rain
It was much wetter than average in the east and southeast over the past seven days, with both Johnstown Castle and Casement Aerodrome reporting more than twice their normal rainfall for this time of year. Dublin Airport was also significantly wetter than average. Conditions were more variable elsewhere, with some western and northern stations recording near- or below-normal rainfall.The weather will be mostly dry today (Thursday), but it will turn unsettled and wet from Friday evening onward. A spell of widespread rain will develop on Friday night, followed by further rain or showers on Saturday and Sunday, heaviest in western and northern areas. Early next week will remain changeable with additional showers or longer spells of rain. Over the 7-day period, rainfall totals are expected to be above average, especially in the west, northwest and midlands.
Temperatures
Mean air temperatures during the past week were slightly below normal, generally between 5 and 8 degrees Celsius. Soil temperatures remained 1 to 2 degrees Celsius above normal, supported by brighter spells in southern and eastern counties.It will be cold today and Friday, with daytime temperatures reaching only the low single figures locally and widespread frost tonight. Temperatures will rise gradually over the weekend, becoming somewhat milder from Sunday into early next week. Over the 7-day forecast period, mean air temperatures will be slightly below the late-November norm, while soil temperatures will decrease slightly, remaining close to normal.
Sunshine
The past week was duller than average in many northern and western areas, with stations such as Malin Head recording just over 6 hours of sunshine. In contrast, the east and southeast were much sunnier, with Casement Aerodrome and Johnstown Castle reporting sunshine totals well above average.There will be good sunshine today and some bright spells on Friday before turning duller from the west as the unsettled weather arrives. The weekend will be generally cloudy, with limited sunshine outside short brighter intervals. Overall, sunshine totals for the coming 7-day period are likely to be close to or slightly above average, owing to the brighter conditions today and early Friday.
Drying Conditions
Drying conditions during the past week were poor to moderate, limited by low temperatures and wet conditions in the east and southeast earlier in the period.Drying will be rather poor over the next two days due to cold conditions, and the wet weekend will bring very poor drying overall. Early next week will offer little improvement as further rain or showers are expected.
Spraying
There will be a short window for spraying today and into part of Friday, with light winds and dry conditions. Spraying conditions will deteriorate sharply over the weekend as widespread rain and unsettled weather move in. Opportunities early next week will remain restricted.
Field Conditions
Soils remain saturated or waterlogged in many areas, particularly in the east and southeast following the recent very wet spell. Although there will be some dry conditions today, poor drying and a wet weekend will prevent any meaningful improvement. With additional rain expected next week, trafficability will remain poor, and poorly and moderately drained soils are likely to deteriorate further.\n
