Tonight

Scattered wintry showers this evening and early tonight in Ulster, some heavy or prolonged especially in northern and western parts. Still a slight risk of thunder too but snow showers will be mainly confined to higher ground. The showers will become isolated overnight and confined to northern and northeastern coastal regions. Very windy for a time also but the winds will veer west to northwest and decrease moderate to fresh overnight. Cold tonight, lows of 1 to 3 Celsius with frost and some icy patches developing, especially later in the night.

Tomorrow

Wednesday morning will be bright and sunny and it will be dry apart from a few isolated showers in northeastern parts. It will become cloudier during the afternoon and, though staying mostly dry, some scattered patches of rain or drizzle will spread into western parts later in the afternoon. Highest temperatures of 7 or 8 Celsius and winds will become mostly moderate westerly in the morning and back southwesterly during the afternoon then freshen on western coasts by evening.
