Winter Storm Threat: Jan 17 (Initial Call)

Here comes the first notable snow event for the southern Mid-Atlantic this winter! A powerful upper-level vort. max will push through the region tomorrow, bringing strong dynamics with it that will help create a period of moderate to heavy snowfall. The snow will start in the morning hours in the higher elevations and will work east through the afternoon and evening. The I-95 corridor will probably start off as rain in the morning. Some sleet could accompany the transition in the late morning and early afternoon, with the changeover to snow occurring around mid-afternoon on I-95 between DC and Richmond. This could lead to large traffic headaches during the afternoon rush hour.

Just in case some people might be thinking it, the current forecast is not favorable for thundersnow/thundersleet.
