Wednesday: Any mist and fog will clear on Wednesday morning to leave a mainly dry day, with just the chance of a few isolated spots of drizzle early on in parts of the west. While it's likely to be rather cloudy at first, mainly in parts of the west and north, sunshine will gradually become more widespread. Highest temperatures will range from 18 to 20 degrees in the northwest and west, but generally in low or mid-twenties, highest across Leinster, where temperatures will be even a little higher locally, up to 27 or 28 degrees.

Thursday: Thursday will bring a good lot of cloud for a time, but it'll be dry apart from a few patches of light rain and drizzle or a few showers, mainly in parts of the west and north. This will tend to clear away northwards with sunshine becoming more widespread from the south. Highest temperatures of 19 or 20 degrees in coastal parts of the northwest and west, but generally in the low to mid twenties, highest across Munster and Leinster, where temperatures will be a little higher in parts. Winds will be mostly light southwesterly or variable.
Friday: It looks like Friday will be a dry day for most with plenty of warm sunshine. However, there's the chance that it could be a bit cloudier further west with a little rain.

Next weekend: It's going to continue very warm or hot by day with temperatures generally in the mid to high twenties, possibly a little higher in places, highest across the midlands and west.
