Nab Scar weather forecast.

Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.

A mixed day on Nab Scar: summit wind broadly 10-25 mph, with gusts 25-35 mph during the evening (fresh and blowy). A meaningful thunderstorm risk is indicated from around midday into the evening. Avoid committing to exposed ridges if storms begin to build. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 700-1000 m) - clear summits. Cloud is likely to hang lowest on eastern slopes; the western side should see somewhat higher bases and better breaks. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain.

Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.

Cloud-free timing: Around 0% early, improving to around 40% later.

A grey, cloudy day on Nab Scar: summit wind broadly 15-30 mph, with gusts 30-40 mph around midday (strong winds). A meaningful thunderstorm risk is indicated from early morning into the afternoon. Avoid committing to exposed ridges if storms begin to build. The ground is likely to be wet after recent rain. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 01:00 until around 16:00. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 100-400 m in the morning, lifting to 400-700 m around midday. Expect clag for much of the day, though a brief clearance is possible during the afternoon. Cloud is likely to hang lowest on western slopes; the eastern side should see somewhat higher bases and better breaks. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 19-31 mph, so treat the headline as mid-range.

Forecast confidence: A low thunderstorm risk remains difficult to time precisely.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Nab Scar: summit wind broadly 5-20 mph, with gusts 15-25 mph around midday (a moderate breeze). Thunderstorms are possible from early morning into the afternoon. Keep an escape route from exposed ridges and descend if thunder develops. The ground is likely to be wet after recent rain. Cloud is likely to hang lowest on southwestern slopes; the northeastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain.

Cloud-free timing: Cloudy early, clearing later.

A mixed day on Nab Scar: summit wind broadly 10-25 mph, with gusts 20-30 mph around midday (fresh and blowy). Thunderstorms are a significant hazard from early morning into the evening. Exposed summits and ridges are a poor choice while storms are nearby. The ground is likely to be wet after recent rain. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 05:00 until around 03:00 the following day. Any cloud sits well above the tops (base 400-1000 m) - clear summits. Cloud is likely to hang lowest on southwestern slopes; the northeastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 15-30 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 15-30 mph, so treat the headline as mid-range.

Forecast confidence: A low thunderstorm risk remains difficult to time precisely.

Cloud-free timing: Cloudy early, clearing later.

A wild day on Nab Scar: summit wind broadly 30-45 mph, with gusts 50-60 mph during the afternoon (gale-force winds). Thunderstorms are possible from the morning into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Much calmer lower down - generally 15-25 mph in the valley, rising towards the tops. Cloud base around 400–700 m in the morning, lifting to 800–1100 m around midday and 1300–1600 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. Cloud is likely to hang lowest on western slopes; the eastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 30-48 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 30-48 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 13 hours on when it arrives.

Cloud-free timing: Around 67% early, improving to around 100% later.

A wild day on Nab Scar: summit wind broadly 25-40 mph, with gusts 40-50 mph around midday (gale-force winds). The ground is likely to be wet after recent rain. Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 500-800 m) - clear summits. Cloud is likely to hang lowest on western slopes; the eastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 27-38 mph, so treat the headline as mid-range.
