We may be heading towards the May but the weather is expected to be very cold this week as overnight temperatures could drop below zero degrees.
Although Monday evening will be dry, a north-west wind will bring temperatures down to zero with a few wintry and possibly thundery showers possible in the north.
Tuesday will be a cold fresh day with the sunshine and heavy blustery showers starting in the north and north-west coastal counties but becoming more widespread through the afternoon before dying out. Overnight temperatures will fall below zero in places bringing wintry showers mainly inland and over Ulster.
As the week progresses, increased cloud cover will allow temperatures to rise slightly as an Atlantic front makes slow progress eastwards, but it will eventually bring unsettled – wet and windy - conditions to all parts during the weekend.
Early indications suggest Friday could hold dry with just increasing cloud amounts, with the wettest and windiest conditions expected later on Saturday and through Sunday.
