Tuesday likely cloudy with rain in the north, especially the northwest, clearing to sunny spells and blustery showers. Initially mostly dry in the south with some sunshine, but likely becoming cloudier with some patchy rain later. Into the rest of the period, the main theme is of high pressure centred to the south, with low pressure systems passing to the north. This will result in frontal systems spreading from the northwest, bringing spells of wet and windy weather mainly to the north and northwest. However, the south is also likely to see some rain at times. In any colder interludes between frontal systems, we will likely see a mixture of sunshine and showers, perhaps wintry in the northeast. Temperatures generally varying between mild and cool, with a frost risk remaining.

The general theme for this period is that the high pressure will remain centred to the south, but may reduce in influence, allowing the frontal systems from the north to push further south at times. This frontal activity and associated changeable weather is likely to bring rainfall, sometimes heavy, especially to the north and west, but also to the south at times. Overall rainfall amounts likely to be below average in the south and east, and near or a little above normal in the north and northwest for the time of year. Temperatures are likely to be at or slightly above average, although brief colder spells remain possible.
