The quoted divisional history shows weather altering a combined-arms plan before the advance begins. Most aircraft intended to support the attackers remain grounded across the Channel, leaving only Normandy-based No. 83 Group available. Heavy overnight rain and mist slow the 44th Lowland and 46th Highland brigades and the tanks of 31st Tank Brigade as they cross soft ground. Their effort opens a way for 11th Armoured Division, but the passage makes clear that air support and mobility depend on conditions as much as on the order of battle.

Weather strips air cover from the Normandy advance
Heavy rain grounds most supporting aircraft and turns soft Normandy ground into an obstacle for British infantry and armour.
