Spring 2013 is likely to make some false starts in Reigate and the SE of England. This week starting 4 March certainly looks warmer but more unsettled with some rain returning as Atlantic influences and LOW pressure take over as the HIGH drifts off south east over the continent. It could reach pleasant max temperatures of 13ºC mid-week in a warm bath of southerly winds but these will be accompanied by some rain. The sketch map shows what models are predicting for Spring after this warm spell ends by this coming weekend. The medium range charts see LOW pressure moving down over the continent and a ridge of HIGH pressure building back up to the north of the UK over the coming weekend.
This could mean cool easterly winds returning from 9/10 March dragging temperatures back to rather wintry like figures by next weekend and beyond. Temperatures could take a significant fall, not as harsh as mid-winter, but certainly down to daytime temperatures of 5ºC again or perhaps even lower; in any case, much cooler than expected for March and possibly even cold enough to bring SNOW back on the agenda!
The north of the UK will fair better if this scenario pulls off update: cold plunge arrives from NE – which will be hit worst … anyhow, expect some ups and downs in the weather and a big false start to Spring.
