Partly to mostly cloudy and chilly with areas of dense freezing fog on Thursday - KRTV

Morning Commute Snarled by Dense Freezing Fog

Dense freezing fog settled across north-central Montana on Thursday morning, reducing visibility below a quarter mile and prompting a Dense Fog Advisory from the National Weather Service that remains in effect until noon, KRTV reported.

Motorists encountered slick roadways and frosted vehicles, requiring extra travel time as temperatures hovered in the mid-to-upper 30s and low-to-40s. The fog is expected to gradually burn off by midday, giving way to partly to mostly cloudy skies across the northern tier. Central areas near Helena anticipate partly to mostly sunny conditions with highs reaching the 40s.

Cloud Cover, Showers, and Friday Conditions

Friday brings continued cloud cover and morning fog, alongside a slight chance of scattered rain and snow showers around the Helena area. Eastern portions of north-central Montana will experience breezy conditions with sustained winds between 10 and 20 mph, while daytime highs remain steady in the 30s and 40s.

Halloween Weekend Outlook

Conditions are expected to improve significantly by Thursday, October 29, leading into Halloween. Trick-or-treaters will find partly cloudy skies, minimal wind, and pleasant afternoon temperatures ranging from the mid-to-upper 40s into the low-to-mid 50s. Most areas will stay dry, though isolated rain and mountain snow showers could develop as a separate weather system approaches the state.

Clock Change and Sunday Storm System

Residents should prepare to set clocks back one hour as Daylight Saving Time officially ends late Saturday night, October 31, into Sunday morning. Emergency services frequently recommend using this biannual time change to test and replace batteries in residential smoke and carbon monoxide detectors.

A more active weather pattern develops on Sunday as rain and mountain snow spread across the region, culminating in widespread precipitation Sunday night into Monday morning before clearing out later in the day. Highs through the early week will stay cool in the 40s and low 50s, accompanied by light breezes of 5 to 20 mph on Monday.

Election Day Forecast

Looking ahead to the next civic milestone, Election Day next Tuesday currently features a forecast of partly to mostly sunny skies and dry conditions. Voters can expect mild outdoor temperatures in the upper 40s and low-to-mid 50s with light winds.
