We are currently in a warm airmass after a generally very cold Spring. The final days of Spring brought a big lift up in temperatures. Today will be warm hazy sunny weather over the eastern half of the country today with cooler air approaching from the west. Cooler air is slowly moving in from the west with the Atlantic trying to break through.

Tomorrow will be fairly mild across most of the country but temperatures down a few degrees on recent days particularly across the southern half of the country with showers beginning to move up from the south and south-west. These may turn thundery in places. Remaining dryer and warmer further north.



The low pressure just out to our west does not look like it will make any real inroads across the country over the next few days with mostly dry conditions to end the week and into the weekend. There may be a few light showers around in places and temperatures will lower further to more average values of 16 to 20C.





Bank Holiday Monday will remain mostly dry but this low pressure just off our west coast may try to make inroads again across western and north-western areas. Temperatures will remain around average 15 to 20C, warmest across the east where sunny spells are more likely.

Rainfall totals over the next week look light away from the far south-west and perhaps western coastal fringes with 10 to 15mm generally depending on shower distribution, some areas could see very little if any rain over the next week or so.

We are currently in a relatively mild to warm pattern of weather although it has cooled down since the warm conditions of the past week. Temperatures look like rising again over the next 5 to 6 days but how long will it last is the question.

There has been uncertainty to how sunny or how warm it will get over the course of the coming week. Over the past few days the models have backed away from a classic 2013/2018 style high pressure fest with very warm to hot conditions. Instead we look on course for a fairly dry and relatively warm week. The warmest conditions look reserved for next weekend, particularly on Saturday before a breakdown may begin as early as Sunday.

Many eastern, central and southern areas may stay dry throughout the coming week with light rain or showers in western and north-western coastal areas at times, but even there, there could be some nice spells of warm sunshine at times too. Not a classic by any means but a nice spell of summery conditions.

Tomorrow will be mostly dry with fairly average temperatures, it may get close to 20C in some eastern areas in spells of sunshine during the afternoon.



Most areas will stay dry but a few light showers may brush up against western coasts at times.



A fairly mild to warm day on Tuesday with spells of sunshine and temperatures reaching 20 or 21C in most places away from western and north-western coastal areas.



Once again light showers may move across western and north-western areas, but many areas will escape these showers.



Wednesday will see the ridge of high pressure become more dominant over Ireland. Temperatures getting into the low 20s in many places, warmest in the east with temperatures of 22 or 23C possible.



Becoming warmer from Thursday with the ridge brushing up against the country with temperatures in the low 20's across the country with temperatures up to 24 or 25C possible in a few areas well inland.





Friday remains fairly warm with low 20s in most places, however cloud or showers may keep western coastal areas cooler.



Next Saturday may see the peak of the warmth with temperatures reaching 22 to 24C widely. By this stage high pressure still in control but low pressure to our west looks poised to make a move soon afterwards.



Trace amounts of rainfall expected for the majority of the country over the coming week, many areas seeing nothing at all, however the far western coastal areas may see 10 to 20mm of rainfall with showers or bands of light rain brushing up along coastal parts from time to time.

The past day or so has seen much cooler conditions spread across the country from the Atlantic. This colder airflow is also right across the UK and delivering some awful conditions particularly for central and south-eastern England today.

The dry spell is still ongoing for most of Ireland despite the cooler conditions. This dry spell will come to a possibly temporary end this weekend with some rain or showers.





The models appear to be backing off rather quickly from an unsettled outlook to a mostly dry scene this coming week and temperatures gradually making a recovery as heights rise.

From Monday today's ECM is showing Ireland largely dry for much of next week with high pressure establishing an influence and keeping us mostly dry with a chance of showers or possibly thunderstorms next weekend.

High pressure moving in from the south-west by Wednesday should deliver a relatively dry week for many.



The UKMO is also on board for some high pressure this week with Thursday also looking rather nice.



We finish the ECM with the possibility of a plume of heat edging over Leinster and low pressure just to our south which may turn things volatile.



As for the GFS it's also rather similar to the ECM and UKMO, we build higher pressure through this week and we get a recovery in the temperatures.



It is also playing around with warmth for next weekend with temperatures into the low to mid 20s.





So it seems the models are backing away very quickly from the cooler unsettled outlook to an improving scene once we get Sunday out of the way. If today's charts verify we could well be on our way for a very, very dry June. The warmth next weekend may not last long as that low pressure to our south could cause us problems with showers or thunderstorms. Interesting model watching over the next few days.
