The Met Office has issued a severe weather warning with freezing fog expected to blanket the area later today (Wednesday 28 December) and until tomorrow at noon.
The warning was issued just after midday today and takes effect from 5pm with the official forecaster saying: “Freezing fog patches will become more widespread and locally dense during Wednesday evening, overnight and through Thursday morning.
“Driving conditions will be difficult with journeys likely to take longer than usual while some delays to air travel are possible.
“A few patches of fog will persist during Wednesday afternoon across East Wales, the Midlands and eastern England, then reforming or thickening up over these areas quickly during the evening and more widely across the rest of the warning area overnight and into Thursday morning.
“While not all areas will have fog, where it does form the visibility could be less than 100 metres.
“Combined with temperatures below freezing, there is also the risk of ice forming on some untreated surfaces particularly later in the night and early on Thursday morning.
“The fog patches are expected to slowly thin during Thursday although some patches may persist throughout the day – most likely in a zone from the West Country to Eastern England.”
