All four of tonight's SSE Airtricity Premier Division games must pass pitch inspections this afternoon, as the cold weather and snow has raised doubts about the playability of some pitches.Derry City's clash with Dundalk at the Brandywell is the first that will be decided as an inspection at 1:30pm will decide whether or not that game can go ahead.The three other games are all due to take place in Dublin which appears to have escaped some of the worst weather that has hit the country.Shelbourne v Shamrock Rovers, St Patrick's Athletic v Bohemians and UCD's clash with Drogheda United will all be decided by 3pm inspections.Temperatures in the capital are not predicted to drop below zero for the rest of the day, and officials will be hopeful that those games in Dublin can go ahead as planned.In Derry, widespread frost and icy stretches will develop later with lowest temperatures of -5 to -2 degrees.
