National Summary

Today

A chilly, dry start in most areas this morning with sunny spells, but showers are affecting north Ulster and these will spread further south over the next few hours, becoming fairly widespread this afternoon. However, much of south Leinster and south Munster will stay dry. Highest temperatures of just 8 to 10 degrees in mostly moderate north to northwest breezes.

Tonight

Showers becoming confined to northern counties this evening. It will then be fairly cold overnight but overall a lot of dry weather under broken cloud. Northwesterly breezes will ease and temperatures will fall to between 0 to +4 degrees Celsius, coldest across southern parts of Munster and Leinster.

Tomorrow

Little change tomorrow Thursday, overall dry but rather cloudy with just some sunny spells. A little showery rain or drizzle too, mostly across the north and east. Northwest breezes will persist, making it another rather cool day, with highest temperatures ranging 9 to 12 degrees Celsius.

Outlook

OUTLOOK: Temperatures improving marginally for May Bank Holiday, but with low pressure very gradually moving in across Ireland. Temperatures should continue to improve into next week however, as winds become east to southeast. FRIDAY NIGHT: Dry across most areas under broken cloud. Light southerly winds will freshen around dawn with patchy rain arriving into southern and western coasts. Lowest temperatures 4 to 7 degrees Celsius, coldest early in the night. SATURDAY: Rather breezy with fresh south to southeast winds. Some scattered outbreaks of rain, with a lot of cloud cover in general. Best of any sunny spells across the midlands, north and east. Highest temperatures 11 to 14 degrees Celsius, with best values across the midlands. SUNDAY: Current indications suggest low pressure will move up over Ireland. Still some uncertainty as to the track of the low, with most of the rain across the south and east. BANK HOLIDAY MONDAY: Low pressure will begin to pull away, so becoming somewhat brighter, rain turning more showery. Some sunny spells breaking through too. NEXT WEEK: Changeable up until midweek, but becoming milder too, as winds begin to feed up from northern Europe.
