Good afternoon everyone Well, I’ll do my best to try and make sense of the next few days rollercoaster weather for you. To sum it up, it goes something like this – cold with some wintry showers, milder but wet and very windy, cold again with wintry showers. I could leave it at that, but I guess a little more detail might not go amiss….. So it’s a story of low temperatures and scattered (locally heavy) hail, sleet and snow showers for the next 24 hours. A covering of snow is possible just about anywhere between now and the end of tomorrow morning. Up to around 5 cm is likely in places, but due to the patchy, showery nature of the precipitation, some places will miss out entirely. As is usually the case, it’s likely to be the higher parts of Northumberland and the Pennines which see most of any snowfall (say above 200-300 m). Trans-Pennine routes are also likely to see snow cover, with 5-10 cm possible in places. The combination of snow and ice will lead to some tricky driving conditions. Then it’s all change, as the next Atlantic weather system arrives tomorrow. Any wintry showers will die away around the middle of the day, as clouds begin to thicken. Outbreaks of rain will arrive through the afternoon and evening (preceded by a short spell of sleet and snow on ground above about 400 m). A spell of heavy rain through the evening and first part of the night, then a return to clearer skies during the early hours. Gale to severe gale force south to south westerly winds will accompany the rain through Wednesday evening and night, veering west to south westerly as the rain clears, with gales or severe gales continuing through Thursday. Gusts of 50-65 mph are likely quite widely, with 75 mph or so in exposed coastal or hilly locations. Some transport disruption is possible, along with the risk of trees being blown over, minor structural damage and the threat to power supplies. During Thursday it’ll begin to turn colder again and we’ll see some scattered showers developing later in the day, which will turn to hail, sleet and snow. The colder air stays with us over the weekend, so we’ll be keeping an eye on the need for snow and ice alerts/warnings. In the meantime, we have a Yellow Warning for snow and ice (low likelihood, medium impacts), valid until midday tomorrow, which extends as far south as parts of North and West Yorkshire. We also have a Yellow Alert for Wind (low likelihood, medium impacts), valid from 15:00 Wednesday to 15:00 Thursday). With so much going on, it’s a good idea to keep up to date with the latest forecast on our website, or by logging onto Hazard Manager. The rainfall radar is good for showing where the wintry showers are at the moment. This was at 12:20 this afternoon….
