As we wake up on Tuesday, September 22nd, it looks like Ireland is in for a fairly mixed bag of weather. If you're anywhere in the southern half of the country, you're probably already seeing a fair bit of cloud, mist, and maybe even a spot of drizzle. That's how our day is kicking off, but as always with the Ireland weather forecast, things are set to shift a bit as the hours tick by.

We've been keeping a close eye on the Met Éireann updates, and it's clear that while some areas are starting off mild, others are going to feel a bit cooler. Let's break down what to expect today, tonight, and even a peek into what the rest of the week has in store for us.

A Cloudy Start, Rain Moving Eastward

This morning, the general picture across the island is mostly cloudy. Those of us down south are dealing with mist, fog, and some drizzle. It's the kind of weather that makes you want to stay tucked in with a cup of tea, but unfortunately, most of us have to get on with our day.

The real shift in the Ireland weather forecast for today starts in the northwest. Rain and drizzle are going to develop there this morning. This isn't a quick sprint; it's a slow, deliberate march. Expect this rain to gradually make its way into parts of Ulster, Connacht, and west Munster as the afternoon turns into evening. Elsewhere, we're looking at scattered showers. So, while it might not be a washout everywhere, it's definitely a day to keep an umbrella handy, especially if you're out and about in the western and northern regions.

Temperatures: A Tale of Two Halves

Now, let's talk about temperatures, because there's a noticeable difference depending on where you are. Generally, the highest temperatures today will range from 17 to 22 degrees Celsius. That's not too bad for late September, certainly quite mild for some.

However, if you're in the west and northwest, you'll be feeling a cooler breeze. Top temperatures there are only expected to hit between 13 and 16 degrees. It's a stark contrast, and it really highlights how local conditions can vary so much across our small island. Winds today will be light to moderate, coming from the south or variable. It won't be particularly blustery, which is a small mercy when you're dealing with rain.

What to Expect Tonight

As Tuesday rolls into Tuesday night, that band of rain and drizzle we mentioned earlier will continue its journey eastwards across the country. Met Éireann predicts it will be heaviest and most persistent in the north, and then later in the east.

After that passes, clear spells and isolated showers will extend from the northwest to most areas overnight. This is when temperatures will really start to drop, falling to between 7 and 11 degrees in most places. However, if you're in the southeast, that cloud and patchy rain might linger a bit longer, meaning temperatures there won't fall below a milder 13 to 15 degrees. We're also looking at patches of mist and fog forming overnight in light and variable winds, so watch out for that on your morning commute tomorrow.

Looking Ahead: Wednesday and Beyond

The Ireland weather forecast for Wednesday, September 23rd, offers a bit more optimism for some. Mist and fog should clear tomorrow morning, and any lingering cloud or patchy rain in the southeast will also make its exit.

We might see isolated showers developing in places, but for the most part, it's expected to be a dry day with some welcome sunny spells and light winds. Temperatures on Wednesday will be a bit cooler than today's highs, ranging from 14 to 19 degrees, with the southeast once again being the mildest spot.

The National Outlook: A Mixed Bag for the Week

If you're wondering what the rest of the week holds, the national outlook suggests a fairly mixed picture. We're in for more rain or showers at times, which isn't entirely unexpected for this time of year. Daytime temperatures for the rest of the week are generally expected to be in the mid to high teens.

Wednesday night: Expect a dry start with clear spells, but cloud will increase overnight. Patches of light rain or drizzle will develop in the west and northwest. Lowest temperatures will be between 7 and 11 degrees, with a moderate southerly breeze picking up.

Thursday: This is shaping up to be a breezy day, with a fresh and gusty southerly wind. Most areas will start dry with occasional sunshine. However, patchy rain and drizzle are expected in the west and northwest, and some drizzle could also hit the south coast. The rain will slowly move eastwards across parts of Ulster, Connacht, and Munster during the afternoon and evening. Highest temperatures will be between 15 and 19 degrees.

Thursday night: Winds will ease, and it'll be mostly cloudy with patchy light rain or drizzle. It's going to feel mild and humid, with lowest temperatures staying quite high, between 11 and 14 degrees.

Friday: Friday morning will be cloudy with patchy light rain or drizzle. This will gradually clear eastwards through the afternoon and evening, making way for sunshine and showers, mainly in the west and north. Highest temperatures will be a cooler 13 to 16 degrees, with light to moderate southwesterly winds.

Friday night: A few showers are expected in the north and west, but otherwise, it should be dry with long clear spells. Lowest temperatures will drop to between 7 and 11 degrees, with light to moderate southerly winds.

The Weekend: Looking further ahead, the weekend starts bright and breezy on Saturday, with sunny spells and scattered blustery showers. Rain is then expected to move into the west later on Saturday, pushing eastwards across the country on Saturday night. Sunday will bring sunny spells and scattered showers. Daytime temperatures over the weekend are set to reach the mid to high teens.

So, there you have it. A typical Irish September, really. A bit of everything, keeping us on our toes.
