Počasí v SZ části Sev. Ameriky opravdu divoké s teplotními vlnami nahoru a dolů. Před týdnem to byly rekordní mrazy, nyní opak - např. kanadské Calgary (byť toto město je "za kopcem") má aktuálně +23 C (normál +5C, tzn. odchylka +18 C). V dané oblasti je nyní výrazná teplotní odchylka do plusu a to +12 až +18 C ! Montana, Sev. i Jižní Dakota, atd. hlásí max. teploty až +23 C. O víkendu pak zase obráceně - studená vlna od severu a propad teplot do hodně záporných hodnot. Divoké ...

Ano v USA jsou ty teplotní skoky opravdu nesmyslné. Koukám na tu Jižní i Severní Dakotu a jsou tam teď teploty přes 20°C a za týden půjdou minima pod -10°C. To bych tady fakt nechtěl. Zlaté mírné Evropské klima.
