Snow showers becoming heavy and frequent in the northwest and north early Saturday morning should extend to many other places (but not all) during daylight hours with the potential for significant falls in the northwest particularly later Saturday evening. The far southeast could stay dry.
For Sunday it will be slightly milder with any showers dieing out and a thaw as a ridge of high pressure builds in - though frosty Sunday night. Lowest temperature around -2c away from high ground.
On Monday and Tuesday a new phase of polar maritime air returns with showers increasingly of snow widespread and heavy at times particularly on hills and in the west.
Temperatures generally between 3 or 4c in the east but lower further northwest and struggling above freezing where any snow settles. Ice restricted due to strong wind except Sunday night.
Winds mostly on the strong side, gales at times.
Depending on how things turn out for later next week this could be the beginning of a longer period of colder weather but that remains to be determined in the next couple of days.
