SUNDAY NOVEMBER 23: A bright sunny day with just a small chance of a shower in a light NW breeze. Highs of 8c to 9c or perhaps 10c. OVERNIGHT: Very cold with frost and fog developing quickly after dark as the light NW breeze drops calm. Lows of between -5c and -2c will result in a sharp to severe frost and coupled with fog will make driving conditions quite hazardous.
MONDAY NOVEMBER 24: Fog will slowly lift during the morning and the frost will thaw. Sunny spells for a time, but during the late morning or early afternoon cloud will quickly build from the west. Winds near calm at first will pickup from the south and clear the fog and frost as the cloud arrives. Highs getting up close to 10c later in the day. During the afternoon or early evening a spell of rain will develop. OVERNIGHT: Wet and windy for much of the night. A clearance before dawn may see some frost, fog and ice develop for a time so once again, driving conditions will become hazardous. Lows of 5c to 8c during the rain, dropping close to 0c before dawn with the clearance.
WEEK AHEAD OUTLOOK: Tuesday will be a cool day with sunny spells with an outside chance of a shower. From mid week onwards it will become more unsettled as low pressure develops to the south of Ireland encouraging a southeast to east airflow bringing showers or longer spells of rain. Cool throughout.
