The first picture can look almost empty: pale cloud, a dark tree and no visible ridge. Keep it. If the weather clears, that frame gives the next one a point of comparison.
Work from an established viewpoint that is safe in the conditions. Check the forecast and local advice before setting out, and decide when you need to leave. Improving visibility does not by itself mean the route is safe. This is a note on composing photographs, not mountain safety advice.
Once you have a position, keep the framing fairly consistent. Photograph the nearest trees, then wait for another part of the slope to become visible. A sequence of three images can show the cloud lifting without requiring a long explanation.
Wet leaves and grass can look strongly coloured under an overcast sky. When editing, compare the whole sequence before increasing contrast or saturation. If one frame suddenly looks much brighter than its neighbours, the edit may be obscuring the change you went there to record.
Write the times beside the selected files. Five minutes and an hour tell different stories. A short caption with that detail is more useful than calling every view dramatic.
