B\u011bhem noci na p\u00e1tek a v\u00a0p\u00e1tek bude po\u010das\u00ed v\u00a0\u010cesku pod vlivem studen\u00e9 fronty, na kter\u00e9 se mohou ojedin\u011ble vyskytnout i bou\u0159ky.

V p\u00e1tek bude foukat siln\u00fd z\u00e1padn\u00ed v\u00edtr o rychlosti 8 a\u017e 13 m\/s, s\u00a0n\u00e1razy v\u00a0ni\u017e\u0161\u00edch poloh\u00e1ch o rychlosti a\u017e kolem 25 m\/s, tj. 90 km\/h, na hor\u00e1ch kolem 30 m\/s, tj. 108 km\/h, na vrcholc\u00edch hor dos\u00e1hne v\u00edtr v\u00a0n\u00e1razech rychlosti a\u017e 35 m\/s, tj. 126 km\/h, tedy ork\u00e1nu.

Bou\u0159ky jsou obecn\u011b projevem lok\u00e1ln\u00edho nahromad\u011bn\u00ed velk\u00e9ho mno\u017estv\u00ed energie v atmosf\u00e9\u0159e, kter\u00e9 je vyrovn\u00e1v\u00e1no proud\u011bn\u00edm v\u011btru.

Relativn\u011b leh\u010d\u00ed, tepl\u00fd vzduch na front\u00e1ln\u00edm rozhran\u00ed, nebo nad p\u0159eh\u0159\u00e1t\u00fdm povrchem vystupuje do vy\u0161\u0161\u00edch vrstev atmosf\u00e9ry. P\u0159itom s sebou nese vodn\u00ed p\u00e1ru, kter\u00e1 se sr\u00e1\u017e\u00ed a vytv\u00e1\u0159\u00ed vodn\u00ed kapky.
