A 100 mph+ jetstream will shift air currently over the Arctic islands of Svalbard all the way down to Majorca in the Mediterranean. This air will travel 3000 miles in around 24 hours. It will bring cold but eventually brighter conditions across the UK as the Atlantic HIGH slips a little over to the East on Thursday. Light snow / sleet / rain showers are likely here and there, especially on Wednesday when shower bands pass over in the morning, but generally they will be few and far between and nothing to get excited about for Reigate, eventually clearing up to clearer skies. Enjoy the crisp Polar sunshine and excellent visibility brought from the Arctic! Sunday and Monday look interesting as a slider LOW (see colour chart) could slip SE down around the HIGH and bring some milder air which meets cold easterlies on their back: a potential recipe for significant snow in the South East. Keep watching for developments. Meanwhile, wrap up – the Arctic winds will feel well below freezing throughout the rest of this week.
