pressure covered the UK and heavy showers developed widely. In Northern Ireland, significant surface water flooding was reported in Enniskillen where many roads were reported impassable for a time. In Manchester a tram line in the Didsbury area was reported closed for a time due to flooding, while

on average (Figure 5a). The surface temperature anomalies were associated with a pattern of higher-than-average sea level pressure over the North American continent, and lower-than-average sea level pressure over much of the Arctic Ocean itself, and the north coast of Siberia, with regions of mild

emitted from the Earth’s surface; the precise algorithm used to convert the microwave signal to ice fraction leads to differences in the measured extent. In 2025, this uncertainty is likely even higher than normal due to a recent change in the satellite sensor used to produce the two indices. Figure 1

of the month. There were also periods of strong winds and heavy downpours, sometimes associated with thunderstorms, at several points in the month. Settled conditions crept in with high pressure on the 21st, but the rain returned on the 27th, widespread but particularly heavy over the west coast of Scotland

now affecting regions further south, we advise motorists to plan well as ice forms on untreated surfaces.  “Drivers should ensure their tyres have plenty of tread and are inflated to the correct pressure to give them the best possible grip on the road. It’s best to stick to major roads, rather

After a period of low-pressure dominance bringing a short-lived return to wet and windy weather, a high-pressure system is on the way. This means cold conditions are likely to take hold, with temperatures falling below average by the end of this week.  Rain, wind, and clear and bright spells

. As the societal impacts of hazardous weather and other environmental pressures grow, the need for a more complete prediction of our complex and interdependent environment is greater than ever to help society make more informed decisions, protecting lives, livelihoods and property, and enabling

(iii) ASXX charts (Actual Surface Analysis Charts) These charts provide the observed pressure information and position of fronts and are produced every six hours. They provide a graphical representation of the weather without the addition of plotted data
