England diary of highlights
Mostly mild but unsettled. A short cold snap during the first week, and a drier spell towards the end of the month. Some stations in northern England had a record wet January.
1st to 4th: A relatively mild start with southerly winds, mostly cloudy skies and some rain in the north. Winds soon turned easterly however bringing much colder air to all areas and with fairly frequent wintry showers over north-eastern areas on the 3rd, with maximum temperatures generally only reaching a few degrees above freezing. The snow was heavy enough to cause some traffic disruption in Northumberland for a time. Milder air spread from the west later on the 4th with strengthening southerly winds giving gales over exposed parts.
5th to 24th: A series of low pressure areas and associated fronts crossed from the west through this period, bringing showers or longer periods of rain and occasional strong winds, with severe gales at times in exposed parts. The 11th was a particularly wet day over southern parts, with over 25 mm of rainfall in places. There were some drier days between weather systems however, with lighter winds. A few night frosts occurred but generally it was fairly mild, exceptionally so in the period 17th to 20th in the south, with some sites setting new record high January minimum temperature on the night of the 18/19th. Preston Wynne (Herefordshire) recorded a maximum temperature of 15.2 °C on the 20th. It was very wet across northern areas on the 21st, with over 40 mm of rain in places (snow over the Pennines), resulting in some localised flooding. Some stations in northern England recorded over 10 cm of level snow on the 21st, with Alston Springhouse Park (Cumbria) recording a minimum temperature of -6.3 °C on 22nd.
25th to 31st: A ridge of higher pressure extended north from France early in this period bringing several days of fine and dry weather for most although with some cool nights and overnight fog. There were some very strong gusts of wind, over 70 m.p.h. to the lee of the Pennines on the 25th.
