    Mesoscale Discussion 0118
    NWS Storm Prediction Center Norman OK
    1208 PM CST Wed Feb 19 2025

    Areas affected...Portions of northern/northeast North Carolina into
    southeast Virginia

    Concerning...Heavy snow=20

    Valid 191808Z - 192315Z

    SUMMARY...Snowfall rates around 1 in. per hour are possible within a
    snow band in parts of northeast North Carolina and southeast
    Virginia. Immediate coastal areas could see slightly higher rates.

    DISCUSSION...As mid-level ascent continues to increase across the
    Mid-Atlantic this afternoon, a coastal trough is expected to deepen
    offshore. By the evening, a deeper surface low should be present off
    the coast from the Carolinas. This process should promote
    low/mid-level frontogenesis across parts of the region. This already
    appears to be occurring in northern/northeast North Carolina into
    southeast Virginia. Wakefield, VA ASOS has reported heavy snow
    within the last 30-45 minutes. This band should continue to
    translate northeastward through the afternoon into the evening.
    Moderate to heavy snowfall is probable within this band with overall
    rates near 1 in. per hour anticipated. Some areas near the immediate
    coast may see slightly higher rates or at least longer duration snow
    as the frontogenetic lift should be maximized in these areas.
    Snowfall intensity will eventually decrease by late evening into
    Thursday morning. With southern extent, towards central North
    Carolina, more of a mix of wintry precipitation is possible along
    the edge of the snow band as there will be greater influence from
    the low/mid-level warm nose.
