1/2 While the 'Raputitsa' seasonal thaw in #Ukraine has lately gained attention (eg halting Russian armour in muddy fields & on unpaved tracks), next week signals a return - at least temporarily - to notably colder conditions. The forecast, especially from around midweek, >>contd 2/2 as shown below from ECMWF model for #Kharkiv (top) & #Kyiv (bottom) calls for overnight lows between -9 to -13C in former; -8 to -10C in latter. Added hardship & peril for those in a humanitarian crisis, especially in areas without functional shelter/power/infrastructure etc.
