2m Temperature: Weekly mean anomalies
Base Time: Tue 05 May 2026 00 UTC T+312 Valid time: Mon 11 May 2026 00 UTC - Mon 18 May 2026 00 UTC
Weekly mean anomalies have been calculated relative to a 20-year model climatology. The areas where the ensemble forecast is not significantly different from the climatology, according to a WMW-test, are blanked.
Note that shaded areas are at 10%, contours are at 1% significant level.
