Monitoring the Situation
The instability across the region is attributed to a clash between warm air from the south and cooler air masses advancing from the west.

Detailed forecasts for Paris and the entire Île-de-France region are also available from Météo-Paris.com, which regularly updates its multi-day outlooks.
