Rain

There was very little rainfall last week, with most areas recording no rainfall. However, it will be a different matter today as thunderstorms break out in a humid continental flow. All areas are at risk and orange status rainfall warning will bring local totals of 50mm, bringing this week's rainfall totals above normal in the matter of a day for some localities. Despite the wet start to the week, the week ahead will bring more usual rainfall amounts.

Temperatures

Mean air temperatures over the past seven days were above average, typically by 2°C. However, parts of Ulster saw just slightly above average temperatures. The week ahead will once again be warmer than average in all areas. In the midlands, the mean air temperature is indicated to be three degrees warmer than normal. However, values are set to slip back from Friday into next weekend. Soil temperatures are above normal for the time of year by up to five degrees.

Sunshine

There was a lot of sunshine throughout the country last week, especially over the last four or five days and amounts range from 200 to 250% of average for the week as a whole. Sunshine will be less reliable through the week ahead. Despite some heavy downpours in the short term, there will be spells of warm hazy sunshine in parts over the next number of days.

Drying conditions

Drying has been excellent overall. However, conditions will deterioirate with the arrival of thundery rain in parts today. Later in the week, Atlantic rain belts will throw up some falls of rain.

Spraying

Conditions for spraying will deteriorate today, but will improve tomorrow well into midweek.

Field Conditions

All lands are trafficable. Soil moisture deficits are high at the moment and may impact on growth in some areas. However, the expected rainfall should help as the week progresses.
