Drying conditions will be generally poor this week, with rain or drizzle at first, followed by colder weather and mainly light winds.
Spraying
Spraying opportunities will be reduced at the start of the week due to rain or drizzle, however from midweek onwards the weather will be more settled so there will be good opportunities for spraying.
