Winter 1947: 'General Inference' and Discussion* at 0600 on 23rd December 1946

General inference-A trough of low pressure extending from southwest to northeast England will move very slowly eastwards and will be followed by a feeble ridge of high pressure. A belt of rain or drizzle affecting much of England and Wales will move move slowly east probably causing some sleet or snow in the extreme southeast of England;mainly fair conditions but with fog developing especially in the industrial areas will spread eastwards behind the rain belt. In Scotland and North Ireland it will be fair apart from a few scattered showers, possibly of a wintry type over hills; local fog will occur. It will be generally rather cold, with local slight or keen night frosts,.
Further outlook-Mainly fair with local fog, risk of rain in west later, rather cold or cold, with night frosts.
At 0600-Wind direction between SW and SE F6 over most of England and Wales. Generally more W'y over Scotland and Ireland behind the front. Extensive cloud but more broken over W. Ireland and W. Scotland.
Plymouth and St.Eval are the warmest places on 48°F (8.9°C). Coldest is Birr Castle on 30°F (-1.1°C)
