Field Conditions
Soil moisture deficits (SMDs) across all soil types currently range between 4 to 18mm in parts of the north, northwest and far southwest, with SMDs of between 40 and 50mm in the far south where there is some restriction to growth. With mixed and often unsettled conditions over the coming week, SMDs will decrease widely by 10 to 15mm with soils in parts of the north, west and north midlands becoming saturated. However, as parts of the southeast and east will be drier than average, SMDs will increase there slightly.
