and regional NWP models. In the global model there are changes to improve boundary-layer processes, the representation of cloud, radiation, warm rain microphysics, and deep convection, whilst in the regional models there are improvements to the treatment of lying snow, sub-grid turbulence and ice

During summer 2023, the Met's Office Wessex Convection Experiment (WesCon) campaign focussed on observing convective clouds to better understand how they form and develop, leading to heavy rainfall and thunderstorms.

-based and remote sensing equipment. This concentration of available measurement platforms coupled with above average summer rainfall for the UK provided a fantastic opportunity to improve our understanding of convection. Routine radar measurements recorded details of the 3D structures of clouds

A band of cloud will linger across central and southern areas, bringing occasional drizzle in places

A band of cloud will linger across central and southern areas through Wednesday morning, bringing occasional drizzle in places. However, this cloud is expected to break from the northeast during the afternoon, allowing brighter conditions to develop. Elsewhere, the day will be mostly dry with sunny

On Monday, early low cloud and isolated fog patches in southern and western areas will soon lift, giving way to widespread sunshine, particularly across central England. Some shallow cumulus and stratocumulus cloud may develop in the south, but it will remain dry. Further north and west, conditions
