Weekend weather: Temperatures to hit at least 21 °C today and tomorrow in Northern Ireland as high pressure dominates

Met Office meteorologist Alex Deakin said there will be “high pressure this weekend which means many of us will be dry and sunny and warm”.

"But as always there is some juicy devil in the detail, as the high pressure is being attacked on two fronts,” he added.

The Met Office spokesman said “we can see the temperatires are going to be above average, 3-5 degrees” and “high pressure is going to last into next week with no sign of much rain around”.

According to the Met Office Northern Ireland today “will be another dry day with long periods of sunshine, perhaps turning hazy at times with areas of high cloud”.

"Becoming rather warm inland by the afternoon but cooler near the east coast. Maximum temperature 21 °C,” it adds.

And tonight “will stay dry through the evening and overnight” with “even sunshine leading to clear spells overnight allowing some patchy mist or frost to develop”.

There will be a minimum temperature -1 °C.

And tomorrow, according tot he Met Office, it will be “dry and bright in the morning after a chilly start” but “becoming warm again by day, with sunshine turning hazy as it becomes cloudier at times later”.

There will be a maximum temperature 21 °C.

The outlook for Sunday to Tuesday, according to the Met Office is that “high pressure will maintain mainly dry and settled weather with sunshine at times, but chance of the odd shower on Sunday and Monday”.

It will be “quite warm inland but cooler along coasts”.

And the forecast for Tuesday 28 Apr - Thursday 7 May is: “High pressure is likely to remain centred close to or over the UK through the remainder of April and into early May.

"This means a continuation of the predominantly dry conditions, likely with a mixture of some cloudier spells and sunnier days.

"For the most part, rain-bearing weather systems should be kept at bay, though the far west and northwest may seeing a little rain at times, although late in the period perhaps an increasing chance of these coming closer into the UK

"Winds will be mostly light, but may be fresher around the coasts at times.

"For most, temperatures will continue above normal, though it will feel cooler along windward coasts in particular”.

And the long distance forecast for Friday 8 May - Friday 22 May is: “A generally more changeable or unsettled spell of weather compared to the previous couple of weeks.

"This comes about as Atlantic low pressure systems move towards the UK, increasing the chance of periods of heavy rain and perhaps strong winds at times.

"Towards the middle of the month, weather patterns become increasingly uncertain; however, the wettest and windiest conditions seem most likely to be in the northwest, with the drier and more settled conditions in the southeast.

"Temperatures will likely be near or a little above normal overall”.
