Update, 9:15 p.m.
Many school systems as well as the Federal government are being ultra-cautious and have already decided to delay Monday morning.

Original post from 4 p.m.
The light wintry mix expected over the region Sunday night into Monday morning may leave behind enough iciness for school delays, especially in our colder areas.
Within a one-county radius of the District, and to the south and southeast, the chances of delays are rather slim (less than 50-50) because precipitation is likely to be light, and air and pavement temperatures will be high enough that any slick spots are isolated.
As you head west of Fairfax and north and northwest of Montgomery and Prince George’s counties, however, the chance of some delays increases.
Delays are not a lock anywhere, but if you live in Loudoun, Howard and Frederick counties, you face a somewhat better than 50-50 chance. There’s even a slight chance that some school systems decide to close, but that would require snow and iciness at the high end of our projections.
Based on the current forecast, we don’t think the federal government will alter its operations on Monday. The chance of an unscheduled leave or telework option is just about 1 in 5.
