Weather conditions conducive to the spread of blight will develop in Connacht and western counties of Ulster and Munster on Sunday and Monday.

Rain

Rainfall accumulations over the past week have varied greatly region to region but most areas have received above average rainfall. Shannon Airport was the wettest with 40mm recorded (over 2.5 times the norm) whilst Cork Airport saw just 6mm (less than half the weekly average for this time of year. It will be a mixed picture this week with the west and northwest expected to receive the bulk of any rainfall ( 150% to 200% of average) with the south and south east staying relatively dry(15% to 40% of average).

Temperatures

Mean air temperatures over the past week have been between 1 and 2 degrees below average countrywide. The coming week will trend near to slightly below average, between zero and 1 degree cooler than normal. Soil temperatures are close to normal between 13 and 16 degrees across the country, and they are expected to remain near normal on average for the coming week.

Sunshine

After exceptionally dull weather at the end of June, sunshine amounts over the last week have returned to near average, with some parts of the southwest having more sunshine than normal for early July. The sunniest part of the country was west Munster with over 40 hours of sunshine in the last 7 days. Sunshine amounts will be variable over the coming week, but current indications are for lower than normal sunshine overall due to the mixed conditions.

Drying Conditions

Moderate drying today in the east and southeast. However, drying conditions are likely to deteriorate into early next week with rain expected at times. However, there are signs that high pressure may build later in the week leading to drier days.

Spraying

Marginal opportunities for spraying Sunday in the east and southeast with mainly dry conditions and light to moderate winds. Rain at times during the coming week will diminish opportunities for spraying but there will be ample opportunities, especially in parts of the south and east of the country.

Field Conditions

Soil moisture deficits have reduced over much of the country with 7% to 24% generally, perhaps slightly higher in the southeast. Elsewhere, soils are generally saturated or near saturation. Little change in deficits is expected in the southeast in the next week. Elsewhere, soils moisture deficits are expected to become marginally drier, away from the west and northwest.
