Storm Forecast Valid: Tue 25 Feb 2014 06:00 to Wed 26 Feb 2014 06:00 UTC Issued: Mon 24 Feb 2014 22:28 Forecaster: TUSCHY
Weak mid-layer height gradients with numerous large-scale vortices linger over S/C and E-Europe. A cyclonic vortex over N-Algeria rotates east and flattens over Sicily/Malta. A NW-SE elongated upper trough over SE-Europe offers no significant motion to the NE. Numerous cyclonic swirls mark the respective centers, which reform constantly on different places within the broad trough. Along with downstream ridging, blocking ridge-over-trough pattern persists over E-Europe. Most active feature will be a slowly filling 970 hPa depression just north of Ireland. Attendant cold mid-layers overspread a vast area from N-Spain to Scotland during the night.
