National Outlook
Overview: The prolonged spell of very warm or hot weather will continue for much of next week. Nights will become very warm and humid too, with some tropical nights likely in parts. It'll remain dry and sunny for most for much of the week, though with an increased chance of some showers or thunderstorms later in the week.
Sunday night: Dry and mostly clear on Sunday night. Lowest temperatures of 14 to 19 degrees, in mostly moderate easterly winds.
Monday: Dry and mostly sunny on Monday. Highest temperatures 23 to 28 generally, highest across Munster and Connacht. Temperatures will be a little lower in parts of the east and north, ranging from 20 to 22 degrees, due to the moderating influence of a mostly moderate east to northeast wind.
Monday night: Dry and mostly clear on Monday night. Lowest temperatures of 13 to 18 degrees in light to moderate northeast breezes.
Tuesday: Tuesday will be a mostly dry, sunny day. There's just the chance of the odd isolated stray shower further south later in the day. Highest temperatures generally of 24 to 28 degrees, warmest in the midwest and southwest, while temperatures will be a couple of degrees lower along the east and north coast, in light to moderate east to northeast breezes.
Wednesday: Wednesday will be an even hotter day and more humid too, with temperatures generally in the mid to high twenties and getting into the low thirties in some areas, hottest across parts of the midwest, west and southwest. Temperatures will be a little lower in eastern coastal parts, mainly in the low to mid twenties, in mostly moderate easterly winds. While it'll stay dry and sunny for most, the heat and humidity may spark off a few sharp showers or isolated thunderstorms, with these most possible across the south and west.
Thursday: Thursday is going to be another widely very warm or hot day, with temperatures again in the mid to high twenties for many, hottest across Munster. Once again temperatures will be a little lower along the east coast, more like the low to mid twenties, in a light to moderate easterly breeze. While it'll continue dry and sunny for many, it looks like there's a higher likelihood of some sharp showers or thunderstorm developing, especially across the southwest and west.
Friday: The hot spell will continue on Friday with temperatures again reaching the high twenties in many areas. It'll be dry for many with sunshine, but there'll be a few scattered showers or thunderstorms around.
Further outlook: There's uncertainty in the forecast into next weekend and while there's a greater likelihood of some rain or showers, there'll still probably be a lot of dry sunny weather too. Temperatures may drop to more normal values for the time of year, though there's a chance also that the hot spell will continue a little longer.
