, though the far north can expect a scattering of showers. Later in the day, cloud will increase across western Scotland and the Northern Isles, bringing occasional rain or drizzle. Winds will be a notable feature in the north, with gusty conditions especially to the lee of hills, while the south

current weather or environmental situations - for example, images of cloud-top height, fog coverage or ash clouds from a recent volcanic eruption. The image data can also be processed to form data-sets suitable for climate applications - for example, historical sea-surface temperature analyses

Thursday will bring largely settled conditions across the UK, with high pressure continuing to exert its influence. Most areas will remain dry, with the best of the sunshine expected in western regions. Elsewhere, cloud cover will gradually break up through the day, allowing sunny intervals

or drizzle over the Midlands in the morning, and cloud increasing generally, with isolated showers in the north-west, and more general rain spreading into northern parts around evening. The 4th was generally cloudy but less cold, with rain affecting all parts except the far north, this rain clearing

high for freezing levels to be largely above summits through the period. Confidence is lower in details, especially the extent of low cloud and the timing of any heavier rain or showers. Headline for Friday 20 Feb 2026: Windy with summit gales. Rain clearing to blustery showers and sunny spells
