Early Snows For The Alps

The models are flagging an unusually sharp start to fall across central Europe.

The latest GFS runs project a completed cold-core low embedded in the polar jet stream at around 300 hPa (9 km) over the Alps by October 1. This setup is primed to deliver heavy snowfall, dragging snowlines down to below 1,500 m (4,900 feet).

Snow depth forecasts show up to 30 cm (1 ft) settling across wide swathes of the central and eastern Alps by midweek:

This is a severe onset for September, and it comes with a broader European chill.

Widespread anomalies of -4C to -8C will engulf the continent this week.
