Cold and windy this evening with clear periods and scattered heavy hail, sleet and snow showers with some dangerous conditions in places.

Tonight

Some very strong northwest winds for a time tonight on parts of the west and northwest coasts. A band of heavy rain and sleet showers will spread southwards early tonight, snowfall becoming mostly confined to higher ground of the north and east overnight. Clearer conditions with scattered showers will follow later tonight and winds will ease. Lowest temperatures of 0 to 3 degrees C. with frost especially in sheltered areas and the danger of icy patches.

Tomorrow

Tomorrow Friday will be cold and breezy. Generally bright with a mix of sunny spells and showers. The showers will be mostly of rain or hail at lower levels, but some sleet or snow on higher ground. Highest temperatures of 4 to 7 degrees C. with fresh and gusty northwest winds.

Outlook

Staying cold for the rest of the weekend and into early next week.Friday night: Cold and very breezy overnight, with a mixture of clear spells and wintry showers. Some snow showers at times, mainly over high ground. Lowest temperatures zero to plus 2 C., with some icy stretches on untreated roads. Winds fresh and gusty north to northwesterly. Saturday and Sunday will be cold, windy days, with bright or sunny spells and occasional showers. Some of these showers will fall as hail or sleet, with some snow on high ground on Saturday and Saturday night and icy patches also. Areas most at risk of the showers are coastal counties of the north, west and east, with many other areas having a good deal, of dry weather, with very few if any showers. Highs each day of 3 to 6 C., and in the stiff north to northwesterly wind, it will feel even colder. Temperatures each night will fall to zero or a few degrees below. Winds will moderate for Sunday night, but later Sunday night, or early Monday morning, a spell of rain and sleet is expected to move in off the Atlantic and this may well be preceded by snow in northern, central and eastern areas. A this stage, it looks as if southern and western areas will have rain on Monday, but this is likely to fall as sleet over Ulster and much of Leinster, with some snow on high ground. Highs on Monday of just 3 or 4 C., in the north and east, but less cold elsewhere, with values 5 to 8 C.
