A weather bomb is defined\u00a0as an intense low pressure system<\/a> with a central pressure that falls 24 millibars<\/a> in a 24-hour period. This phenomenon is known to meteorologists as ‘explosive\u00a0cyclogenesis’ and often leads to high winds and heavy rain, or snow, if the temperature is low enough.<\/p>\n

On Boxing Day<\/a> evening, this is exactly what happened as the ‘bomb’ tracked across North Wales<\/a>, the North Midlands<\/a> and South Yorkshire<\/a>. Unfortunately, the southern edge of the system passed over Bracken House resulting in nine centimetres of snow falling between 17:00 and 02:00 the following morning.<\/p>\n

The maximum pressure recorded was 1030.0 millibars at 00:08 on the 26th. This fell to 1004.7 millibars at 22:15 – a drop of 26.3 millibars in a little over 22 hours. This brought a short spell of rain around dusk, which quickly turned to snow after dark. The fall resulted in Selston<\/a> being almost cut off for a few hours.<\/p>\n

Normally, Selston is well gritted, sometimes\u00a0when it isn’t really necessary, but on this occasion, Nottinghamshire County Council<\/a> got it all wrong and no gritters were seen. It was left to\u00a0the local councillors and residents to work until the early hours gritting the hills and helping to free trapped motorists.<\/p>\n

The temperature hovered just above freezing all night, but the biting wind\u00a0chill of -5.2\u00b0C was the lowest recorded this year. The snow depth<\/a> was around nine centimetres, although 14 centimetres was measured in more exposed areas of the garden.<\/p>\n

The following day saw bright sunshine, but with temperatures peaking at 2.2\u00b0C, this had little impact on the lying snow.<\/p>\n
