    Concerning...Freezing rain=20

    Valid 021834Z - 022230Z

    SUMMARY...Freezing rain may continue through the afternoon, and may occasionally mix with sleet. Modest ice accretion is possible.

    DISCUSSION...Precipitation has gradually increased in coverage
    through the morning across western/central NE, in association with
    midlevel shortwave trough moving east-southeastward across the
    region. Initial dryness in the 850-700 mb layer (as observed in the
    18Z OAX sounding) has likely limited precipitation amounts to some
    extent, but a modest increase in rates is possible into mid
    afternoon as saturation occurs and precipitation continues. The
    surface freezing line is currently oriented north-south across
    west-central NE, and is expected to make only slow eastward progress
    through the afternoon, as ongoing precipitation and low-level
    cold/dry advection help to maintain subfreezing conditions farther
    east.=20

    The bulk of the afternoon precipitation will fall where surface
    temperatures will remain below freezing. Some sleet will be possible
    within the colder environment across north-central/northeast NE, but
    short-term guidance continues to indicate primarily freezing rain
    across central NE, where a shallower subfreezing layer will be in
    place. Precipitation will generally remain rather light, but 3-hour
    rates may approach or exceed 0.05", with modest ice accretion
    possible.
