Wintry mix predicted for weekend
The Northern Shenandoah Valley will experience another bout of winter weather late today into Saturday, according to Luis Rosa, a meteorologist at the Sterling office of the National Weather Service.
Snow accumulation figures are not expected to exceed an inch, but the precipitation is expected to be a wintry mix of freezing rain, sleet and snow, which could result in some minor, yet potentially problematic ice accumulation. Today’s high will be 49 with the low predicted to be 32 degrees. The Saturday high is forecast near 33.
“Initially it will be a little bit of snow changing quickly to freezing rain or sleet,” Rosa said. “(It will be) mainly early Saturday possibly changing to rain on Sunday morning. (There will be) up to an inch of snow. It’ll start late Friday night, early Saturday morning.”
He said that ice accumulation is expected to be up to a tenth of an inch.
Rosa explained the weather events that will create conditions when wintry precipitation can occur.
“There will be a cold front pushing through the area tomorrow (Friday) during the day,” Rosa said. “There will be a low-pressure system developing over the mid-section of the country. There will be warm air drawn northward.”
Rosa said that some higher ice accumulation figures are expected for areas to the west and north of the valley, in places such as Allegheny County, Maryland. Accumulations are expected to be consistent throughout the Northern Shenandoah Valley.
Rosa said that the unseasonably warm weather felt in the area on Thursday could impact accumulation.
“Everything is pretty warm so that cold air is going to take some time (to) filter into the area,” he said.
