Iskylan stramar \u00e5t sitt grepp om Sverige.\u00a0<\/p>\n

Februaris f\u00f6rsta dag kan bli ett s\u00e5 kallat nationellt isdygn. Det inneb\u00e4r att temperaturen ligger under noll i hela landet ett helt dygn.<\/p>\n

\u2013 Det skulle absolut kunna bli ett nationellt isdygn i morgon s\u00f6ndag, s\u00e4ger Emma H\u00e4renstam, meteorolog p\u00e5 SMHI<\/a>.\u00a0<\/p>\n

SMHI r\u00e4knar ett temperaturm\u00e4ssigt dygn fr\u00e5n klockan 19 och 24 timmar fram\u00e5t. Allts\u00e5 beh\u00f6ver det vara minusgrader \u00f6verallt fr\u00e5n och med klockan 19 p\u00e5 l\u00f6rdagen, till klockan 19 p\u00e5 s\u00f6ndag, f\u00f6r att ett nationellt isdygn ska registreras.<\/p>\n

H\u00e4r kan det bli nollgradigt<\/p>\n

Kuststationerna i s\u00f6dra G\u00f6taland hotar dock s\u00f6ndagens potentiella isdygnsstatus, enligt SMHI.<\/p>\n

\u2013 D\u00e4r kommer temperaturerna ligga runt noll grader. S\u00e5 det h\u00e4nger lite p\u00e5 dem om vi f\u00e5r ett nationellt isdygn eller inte, s\u00e4ger H\u00e4renstam.<\/p>\n

Fenomenet brukar intr\u00e4ffa n\u00e5gon g\u00e5ng per \u00e5r, men vissa \u00e5r uteblir nationella isdygn helt. Om s\u00f6ndagens prognos h\u00e5ller i sig kommer det bli det f\u00f6rsta isdygnet f\u00f6r s\u00e4songen.\u00a0<\/p>\n

\u201dH\u00f6gtrycksblockering\u201d<\/p>\n

Oavsett kan hela landet r\u00e4kna med riktig kyla inom en \u00f6versk\u00e5dlig framtid. En \u201dh\u00f6gtrycksblockering\u201d ligger \u00f6ver Sverige, vilket betyder att h\u00f6gtrycket som f\u00f6r med sig minusgraderna ligger kvar v\u00e4ldigt l\u00e4nge.<\/p>\n

\u2013 Just nu pekar det faktiskt \u00e5t att vi kommer ha det h\u00e4r v\u00e4derl\u00e4get ett bra tag fram\u00f6ver, ett h\u00f6gtrycksbetonat och kallt v\u00e4der.<\/p>\n","protected":false},"excerpt":{"rendered":"Publicerad 31 jan 2026 kl 10.10Uppdaterad kl 11.27 Minusgrader \u00f6verallt i 24 timmar.
