Mostly sunny skies will be the start to our weekend

I270 Forecast

Good Friday! A cold front will linger across our area, bringing us cooler air throughout our Friday night into Saturday. Gusty northwest winds will continue to decrease our temperatures. There is a chance for upslope snow showers across the Allegheny Front. Cloudy skies will be the norm for our Saturday in front of the upcoming winter storm. Many locations will struggle for high temperatures to rise above freezing, with higher terrains stuck in the low 20’s. Wind chill values will remain in the teens for most locations during the daylight hours after starting the day with wind chill in the single digitals or near zero. High pressure will move through our area Sunday night, with the high remaining off to the north.

Low temperatures on Saturday could dip into the single digits, which could be the coldest temperatures since 2019. We start our Sunday off mostly dry but chilly. The National Weather Service expanded the Winter Storm Watches across portions of I-95 and throughout the Washington D.C. metro area as a winter storm approaches our area. Now, this watch will not go into effect on Sunday afternoon. The watch most likely will expire early Monday morning, except for places along the Allegheny Front, where the watch will expire at lunchtime. Snow, sleet, and freezing rain will be the main precipitation type for this upcoming storm. The timing of this storm is key to the amount of snow that will fall across the area. Northern Virginia and D.C. will be the first to see the snow arrive around 4-5 on Sunday afternoon. Whereas the snow for the rest of us will move through Sunday evening. As for snow totals, west of I-95 could see 1-3 inches of snow, whereas east of I-95 could see anywhere between 3-5 inches of snow. Across the Eastern panhandle of West Virginia and Garret and Allegheny Counties of Maryland can see anywhere between 5-8 inches of snow. However, we will see the transition from snow to freezing rain and sleet heading into Monday. Heavier ice accumulation will be between I-81 and US-15. There is a possibility for minor flooding as the snow/sleet changes over to plain rain, mainly near and east of the I-95 corridor.

Stronger winds are expected east of the corridor as the low exits our area. Wind gusts are expected to be 45 mph + along the Allegheny Front and the Blue Ridge. With strong winds across this area, this could cause blizzard-like conditions. At times we can see close to an inch to two an hour of snow falling. We start Monday off soggy as the low moves out into PA. This low will begin to funnel in cooler air and rush into our area. Some linger snow could be possible for the first couple of places on Monday morning. But as the low moves out to the east, we will begin to dry out but still be cold. Moderate and heavy snow will continue to fall across the Allegheny Front Monday afternoon into Monday evening. Gusty winds will still be a factor for our Monday. Northwest winds could cause a Wind Advisory for the area Monday night. This could create blizzard-like conditions within the Allegheny Front. On Monday, high temperatures for the mountains will remain in the 20’s, whereas the rest of the area could see temperatures in the upper to lower 40’s.
We will settle down Tuesday as an upper-level trough moves northeast and high pressure builds in. Mostly sunny skies are expected for our Tuesday, with high pressure gradually moving out Wednesday. Highs will be in the mid 40’s for our Wednesday, with a chance of us seeing some rain showers. A cold front will move in Wednesday night and dip our temperatures back down into the 30’s for Thursday with dry conditions.
