Areas affected...portions of southern Georgia into northern Florida

Concerning...Winter mixed precipitation=20

Valid 220452Z - 220745Z

SUMMARY...A wintry mix should continue into the early morning hours,
with instances of moderate snow, sleet, and perhaps freezing rain
expected.

DISCUSSION...A belt of strong 700 mb warm-air and moisture advection
is overspreading southern GA into northern FL in response to a
rapidly approaching mid-level trough. While RAP forecast soundings
suggest that much of the vertical profile below 600 mb may be above
freezing at several locales, 04Z mesoanalysis shows strong
surface-850 mb CAA impinging on the GA/FL border, where MRMS mosaic
radar data shows bright banding taking place, and where surface
observations indicate snow, sleet, and freezing rain becoming the
predominant precipitation modes. Continued CAA should result in
wintry mixed precipitation overspreading the rest of far northern FL
and continuing into the early morning hours, in agreement with the
latest high-resolution guidance consensus.
