Time to set your heating as temperatures are forecast to drop dramatically

Temperatures are set to drop dramatically overnight with frost and fog forecast for early on Saturday morning. 

It might be worth setting your heating timer now as it will be particularly cold on Saturday morning as temperatures are set to fall to as low as 1C. 

Met Éireann predicts that Friday will be fresh with sunny spells and scattered showers - most frequent and heavy across the north and northeast. The showers will gradually clear away into the Irish Sea during the afternoon, with sunnier skies developing more widely from the west. Moderate to fresh northwest winds will ease through the day too. Highest temperatures of 12 to 15 degrees.

Tonight will dry, calm and clear, though some mist and fog patches will set in too.

However, it will be a rather cold night with lowest temperatures of 1 and 7 degrees.

Tomorrow will start chilly but largely dry with spells of hazy sunshine. However, early brightness will be replaced by cloudier skies as outbreaks of rain and drizzle gradually move up from the southwest of the country, heaviest later. Highest afternoon temperatures of 11 to 16 degrees (north to south) with mostly fresh and gusty south to southeast winds.
