FI Charts ( T120+ onwards) Summer2024 **READ MOD NOTE IN FIRST

31-05-2024 6:25pm#1
After a very wet 2/3s of Spring, the season improved during May and overall Spring was yet another very much milder than average season. Summer is here now so how are things looking for the first half of June?

Mod Note:This thread is for posting/discussing/analyzing FI CHARTS ONLY i.e. Charts in the unreliable time frame, generally +T120 onward for Summer 2024.
If your post does not specifically relate to an FI chart then it doesn't belong here - Off topic posts will be moved
Thanks

The first day of Spring has high pressure ridging in from the west bringing a dry and settled weekend to come. Temperatures will be around average with most places sitting between 15 and 18C. A few places might pull off 19 or 20C.
This spell of high pressure does not look like it will stick around for long, this high pressure got downgraded fairly rapidly over the past few days in duration and temperature. By Monday the high pressure will already be on the move with winds in from the north-west bringing cooler conditions. A cold spell is likely from mid week onwards with a chilly north-west airflow. This could bring showers at times to western and northern areas with temperatures overall sliding away into the low teens.
Into next weekend we see another attempt at a ridge of high pressure building, but for now this looks very flimsy and maybe not last more than a day or so.
On this GFS 12z we see the Atlantic making a comeback with a more unsettled pattern setting up for the second week of June with rain and relatively cool temperatures.
The second week of June becomes progressively more unsettled as it goes on with low pressures centred over Ireland or close by.
We finish up with a cool Atlantic pattern well in control. Hopefully my next update will be looking better as this first half of June is currently not looking particularly great by any means.

Rest of this week is looking chilly and dryish but will be some showers around so it won't be completely dry. 2 to 5mm of rainfall between now and Sunday across most of the country, wetter in Donegal and Sligo with more in the way or rain or showers there.

Looks like temperatures starting to pick up slowly and gradually, rainfall fairly low away from the W and NW.
LP nearby out in the Atlantic , will see if a trend builds that the HP will block them, keeping them well off the West.

A fairly major pattern change could begin to take place later this week to something much warmer. It wouldn't be hard considering temperatures have been well below average for over 2 weeks at this point. What is uncertain is will it change to warm/hot and settled or will it change it warm and volatile with heavy showers or thunderstorms etc, time will tell.

That is some set of charts from the ECM, runs over the last few days being leaning more towards warmer and drier weather, after Fridays expected rain very little of note after that showing up for now. That would be some temperature change from all the cooler fresher weather of late, night temps getting no lower than 16 to 18C some nights in places. A scorcher by Irish terms.
GFS equally a lot less rainfall, temps into the low 20's

Complete different look to the charts since just a couple of days ago. Into the mid 20's Sun and Mon and maybe touching that Tues in the E but low pressures from the Atlantic seem to have won the battle bringing in bands of rain and showers at times from Tuesday and thereafter the models showing a drop off in temperatures…gone from the mid to high 20's down to maybe the high teens at best and from relatively dry to now expecting a fair shot of rain at times. Of interest to some perhaps will be the watch for thunderstorms next week to see if they materialize.
