Why was Winter so Mild?

Just why was this Winter so mild in Ireland a lot of people are asking?

• High Pressure Remained to the South bringing Southwesterlies
• Low Pressure was much further North than 2010
• Increased cloud cover at night due to moist airflow
• Warm Sea Temperatures
• Winds coming in from the Atlantic
• Siberian Air just failing to reach our shores
• Windy weather at times prevented frost
• Lack of mobility at times meant prolonged mild spells
• Lack of Cold Weather in Europe until February

Sunny days were rare this Winter in Ireland
