Base Time: Wed 19 Mar 2025 00 UTC T+288 Valid time: Mon 24 Mar 2025 00 UTC - Mon 31 Mar 2025 00 UTC

The anomalies have been calculated relative to a 20-year model climatology. The areas where the ensemble forecast is not significantly different from the climatology are blanked.

A “warming stripes” are a visual representations of the change in temperature. **#ShowYourStripes**
