Currently mostly cloudy and chilly conditions prevail as a weak zone of high pressure moves east of the Northeast Seaboard. The high will leave the coast later Sunday morning and yield to a fast-moving jet stream disturbance currently over the mid- Mississippi Valley.
While the disturbance is just producing a little light snow from Illinois to Ohio, we expect that it will intensify slightly as it reaches the Northeast Seaboard. As the disturbance approaches, clouds will thicken Sunday morning. The morning will be dry, then some light snow mixed with rain south of the city will arrive around mid to late afternoon and continue for 3-5 hours before tapering to flurries Sunday night.
Most places will receive just a coating to an inch, with none expected south of the city and up to an inch north of the city.
