Storm Team4's Doug Kammerer has your Thursday evening forecast.
The D.C. area is in for a deep freeze once again Friday. While temperatures will ease over the weekend, frigid air returns next week.
A wind chill advisory is in effect until 9 a.m. Friday as wind chill temperatures from -5 to -10 are expected.
After three days of closures and delays, most of the region's major school districts will welcome students back to class Friday. Some school systems, including Fairfax County and Prince George's County, are instituting a 2-hour delay. A number of schools in outlying areas will be closed.
Pepco is asking customers to conserve electricity between 3 p.m. and 7 p.m. Thursday and 6 a.m. and 9 a.m. Friday if health permits. Pepco recommends setting thermostats lower, not using major electric appliances, and turning off lights and appliances not in use during those times.
A parade of clipper systems will move through the region in the coming days bringing minor snow chances and reinforcing cold air. A clipper moves through on Saturday with a chance of snow (1 inch or less), especially north and east of D.C. Temperatures warm above 32 degrees on Saturday, but wind gusts could reach 35 mph. A clipper moves through on Monday, bringing little or no snow and reinforcing the cold with highs in the mid-20s for Tuesday and Wednesday.
Storm after storm is bringing the cold air straight down from Canada, and with nothing to move it out, the region could be in the cold for the next 7-10 days.
