At cruising altitude for the first 600 NM after initial climb.

Clear for the first 1500 NM or so and then likely for the rest of the cruise.

It is NOT expected to encounter a high concentration at cruising altitude on this route.

At cruising altitude for the last 600 NM before descent.

A line of Lenticular cloud will be followed by a rapid drop in temperature and severe rime ice.

A cloud will increase rapidly from a Cirrus layer, to Cirrostratus then Altostratus and Nimbostratus, producing

A band of Stratocumulus clouds will rapidly lower its base into frontal fog.

A distinct roll cloud will be followed by a sudden, rapid increase in wind.

The wind strength normally increases by a factor of 2 per 1000 feet up to the 850 hPa level.

The wind normally backs during climb out through the first 2000-3000 feet in the northern hemisphere.

The wind strength normally increases by a factor of 2 per 500 feet up to the 700 hPa level.

The wind normally veers during climb out through the first 2000-3000 feet in the northern hemisphere.
