Another very wet, windy and extremely mild winter has passed and it's time to move on and focus on Spring 2024.
------------------------------------------------------------------------
Mod Note:
This thread is for posting/discussing/analyzing FI CHARTS ONLY i.e. Charts in the unreliable time frame, generally +T120 onward for Spring 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

March looks like it will start off on a chilly note with wintry precipitation on Thursday night and into Friday which could deliver the first flakes since Spring 2023 for eastern and some central parts of the country. Lying snow is possible to low levels but this will be very transitional and short lived.
We remain unsettled and cool into the first week of March with plenty of cold rain and daytime temperatures generally in the high single digits.
After next weekend we go into the unreliable time frame. The GFS 6z is playing around with an easterly of sorts and depending on exact wind direction this could be rather mild if there is a south-east source to the easterly or cool if it's a direct easterly. We may get a bit of a recovery in the temperatures by this point to more average values rather than slightly cooler than average.
We're getting to that time of year where easterlies need to be direct hit and sourced from the north-east to pull in any real cold and this seems unlikely.
We finish up with winds still in from the east but sourced from a warmer south-eastern parts of Europe so no cold air associated with this easterly.
Overall the coming 2 weeks look fairly wet with large rainfall totals possible in western areas.

The ICON op run following other models with an easterly. Nothing particularly cold by 180hrs but the Siberian tap is dripping and much colder air is not too far away. Not sure my heart is in it for a Spring time snow chase 🥵 The moisture content is high and ground is warmer.

LP looks set to be dominant with some high rainfall totals out to +240hrs being indicated on some of the models. Temps cool next week no great improvement showing up just yet with models showing some cold or frosty nights next week and into the weekend. The Jet staying South of us for now.

Unfortunately no, it's about to get worse even wetter than the past few weeks is very possible for next week. Turns very wet from Monday with no shortage of rainfall all through next week and into next weekend and possibly beyond.
For Dublin that is a very wet GFS ensemble graph particularly from 2nd April to 10th April with a possible drying trend into the far depths of FI around the 14th of April. Expect places further west than this to trend even wetter. Many parts of the country could easily achieve 100mm of rainfall or more over the next 2 weeks.

I'll take it at this stage if it stops the rain. Just having a look at the GFS 06z that just finished its run. It's showing the conveyor belt still going up to the weekend of the 12th, with a deep low sitting over Iceland pulling low pressure up towards us and the high pressure staying well south. It shows pressure building in the Atlantic after that and ends with high pressure sitting right over us on the Tuesday but it seems on each run that higher pressure just keeps getting pushed out. The signals are consistently there though for things to begin settling down.
