I kdy\u017e se dnes bou\u0159ky vyskytnou na v\u011bt\u0161in\u011b \u00fazem\u00ed (t\u0159eba i na Z a JZ \u010cech), nejsiln\u011bj\u0161\u00ed mohou b\u00fdt hlavn\u011b ve v\u00fdchodn\u00ed a severov\u00fdchodn\u00ed polovin\u011b \u00fazem\u00ed. Dominantn\u00edm \u00fatvarem, kter\u00fd bude iniciovat vznik bou\u0159ek b\u011bhem odpoledne a ve\u010dera, bude konvergence \u2013 sb\u00edhavost p\u0159\u00edzemn\u00edho proud\u011bn\u00ed, kter\u00e1 se u\u017e od rann\u00edch hodin udr\u017euje p\u0159ibli\u017en\u011b v oblasti od jihu Vyso\u010diny\/JM kraje k Jesen\u00edk\u016fm. Pr\u00e1v\u011b zde bude bou\u0159ek nejv\u00edce.<\/h6>\n

Dal\u0161\u00ed oblast, kde mohou b\u00fdt bou\u0159ky intenzivn\u011bj\u0161\u00ed, bude na v\u00fdchod\u011b a severov\u00fdchod\u011b \u010cech, \u010d\u00e1ste\u010dn\u011b i ve st\u0159edn\u00edch oblastech \u010cech. Zde bude bou\u0159ek ale plo\u0161n\u011b sp\u00ed\u0161e m\u00e9n\u011b.<\/p>\n

V\u0161echny bou\u0159ky, kter\u00e9 se dnes vytvo\u0159\u00ed, budou postupovat sm\u011brem k severov\u00fdchodu a\u017e v\u00fdchodu. Dostupn\u00e9 energie nebude v atmosf\u00e9\u0159e mnoho, ale jej\u00ed vertik\u00e1ln\u00ed distribuce v r\u00e1mci atmosf\u00e9ry nazna\u010duj\u00ed hlavn\u011b riziko intenzivn\u00edch p\u0159\u00edvalov\u00fdch sr\u00e1\u017eek. V potenci\u00e1ln\u011b zasa\u017een\u00fdch oblastech je sice v\u011bt\u0161inou mimo\u0159\u00e1dn\u00e9 sucho, pokud se ale bou\u0159ka \u201estref\u00ed\u201c hlavn\u011b do hust\u011bji obydlen\u00fdch oblast\u00ed a v\u011bt\u0161\u00edho m\u011bsta, mohou nastat komplikace. Riziko bude i v opakovan\u00e9m p\u0159echodu bou\u0159ek p\u0159es jedno m\u00edsto hlavn\u011b v oblasti konvergence na Vyso\u010din\u011b a na Morav\u011b, \u010d\u00edm\u017e se mohou \u00fahrny je\u0161t\u011b navy\u0161ovat.<\/p>\n

\u00dahrny lok\u00e1ln\u011b kolem 30 mm\/hodinu se mohou tu a tam objevit, v opakovan\u00fdch bou\u0159k\u00e1ch i v\u00edce.
\nV izolovan\u011bj\u0161\u00edch bou\u0159k\u00e1ch hlavn\u011b zpo\u010d\u00e1tku se mohou vyskytnout i men\u0161\u00ed kroupy nebo n\u00e1nosy mal\u00fdch krup. Lok\u00e1ln\u011b mohou m\u00edt bou\u0159ky tak\u00e9 tendenci se formovat i do lini\u00ed (tzv. squall line), v takov\u00e9m p\u0159\u00edpad\u011b o\u010dek\u00e1v\u00e1me i vy\u0161\u0161\u00ed n\u00e1razy v\u011btru, hlavn\u011b v oblasti v\u00fdchodn\u00edch a severov\u00fdchodn\u00edch\/severn\u00edch \u010cech, kde bude su\u0161\u0161\u00ed vzduch v ni\u017e\u0161\u00edch hladin\u00e1ch.<\/p>\n

Bou\u0159ky budou v oblasti Moravy a na V \u010cech sl\u00e1bnout ve ve\u010dern\u00edch a pozdn\u00edch ve\u010dern\u00edch hodin\u00e1ch a postupn\u011b p\u0159evl\u00e1dne sp\u00ed\u0161e intenzivn\u011bj\u0161\u00ed, ale plo\u0161n\u00fd d\u00e9\u0161\u0165, kter\u00fd bude ovliv\u0148ovat Moravu a hlavn\u011b Slezsko a\u017e do rann\u00edch hodin.<\/p>\n

Upozor\u0148ujeme, \u017ee bou\u0159ky a tedy i \u00fahrny sr\u00e1\u017eek budou hodn\u011b lok\u00e1ln\u011b prom\u011bnliv\u00e9.
