Apex Weather

St. John Valley weather for Dec. 29, 2021-Jan. 4, 2022

Three-day outlook: Wednesday-Friday

High pressure will build across the SJV today though low-level moisture trapped underneath drier air higher aloft will keep plenty of clouds over the region. A weak area of low pressure and associated fronts will approach from the Great Lakes later today with snow showers overspreading the Valley this evening.

Steadier snowfall is expected to develop Thursday with a slight chance for snow over the course of the day and a chance for snow Thursday night as an occluded front associated with the low pressure area moves through. Snow showers linger Friday under partly sunny skies. Little moisture is associated with the system and no significant accumulation is anticipated.

Today and Tonight

Mostly cloudy with a 20 percent chance for afternoon snow showers. High near 25 degrees. Northwest winds near 3 mph.

Tonight, cloudy with a 30 percent chance for snow. Less than 0.10-inch precipitation. Low around 18 degrees. Southeast winds near calm.

Thursday, December 30

Mostly cloudy with a 30 percent chance for snow. Precipitation totals less than 0.10-inch. High around 28 degrees with south/southeast winds 0-3 mph.

Friday, December 31

Mostly cloudy in the morning then partly sunny in the afternoon with a 30 percent chance for snow. Less than 0.10-inch precipitation. High around 29 degrees. Southeast winds near calm.

Friday night, mostly 3cloudy with a 0 percent chance for snow. Low near 23 degrees. Southeast winds 0-7 mph.

Four- to seven-day outlook: Saturday-Tuesday

Mostly cloudy skies are expected Saturday with increasing chances for snow, mixing with rain, in the afternoon. Forecast model variability is high for the weekend; however, presently, low pressure moving up from the Mid-Atlantic/Ohio Valley will bring a chance for snow/rain Saturday afternoon with snow Saturday night into Sunday tapering off by Monday morning. Due to model inconsistency, precipitation type, amount, and duration are still uncertain at this time and will ultimately depend on the strength and track of the system. Partly cloudy skies and much colder conditions are expected Monday and Tuesday as an Arctic air mass moves into the SJV.
