  experience calmer conditions, only for winds to increase sharply again after moving further west, highlighting the influence of local terrain. Elsewhere across southern England, it will also feel breezy at times, even though the overall weather remains dry and bright. Why the air is so dry One

  temperatures, 83% was the level of accuracy for the 1-day range, with this dropping to 58% at 5-days. Wind speed is assessed as accurate if it’s within five knots of the verifying observation and comes into sharp focus during the stormy winter season. 89% of wind speed forecasts at the 1-day range were

  and wind direction can create sharp rainfall gradients. For instance, Aberdeen recorded around 120mm of rain in the first nine days of February, while Aviemore, protected by mountains, saw only about 2mm during the same period. These contrasts illustrate the profound effect of flow direction on local

A sharp dip in temperature later in the week A noticeable downturn in temperatures will arrive from Thursday into Friday as colder air is drawn south behind an active frontal system. By Friday morning, daytime highs across much of the UK fall below

Thunderstorms are associated with deep convective clouds, called cumulonimbus and are most often, but not necessarily, accompanied by precipitation at the ground. This factsheet describes how cumulonimbus clouds form, how they produce lightning, how it can

This may present confusion for stakeholders looking to use projections beyond 2100 to make decisions, giving the false impression of a period where sea-level could decrease sharply before rising again. • The different treatment of vertical land motion and landwater storage
