Des Moines, IA –
The National Weather Service in Des Moines has issued a Frost Advisory for portions of north-central Iowa overnight, following a day of strong northwest winds and cooler air sweeping across the state.
A Wind Advisory remains in effect through 6 p.m. CDT Tuesday, October 21, with winds between 25 and 30 mph and gusts up to 45 mph expected across much of northern and north-central Iowa. Affected areas include Waterloo, Mason City, Algona, Emmetsburg, and Grundy Center.
Forecasters say the gusty conditions could blow around unsecured objects and potentially knock down small tree limbs, leading to isolated power outages.
Later tonight, as skies clear and winds calm, temperatures are forecast to drop near 32°F, prompting a Frost Advisory from 2 a.m. to 9 a.m. CDT Wednesday for Pocahontas, Humboldt, Wright, and Franklin counties. The NWS warns that frost could damage sensitive vegetation and advises residents to cover outdoor plants or bring them inside.
Wednesday morning is expected to be chilly but sunny, with gradually warming temperatures later in the day as high pressure builds into the region.
