Areas affected...portions of central into southern Arkansas and
northern Mississippi

Concerning...Freezing rain=20

Valid 100403Z - 100900Z

SUMMARY...Freezing rain should continue across central and southern
AR over the next several hours, with freezing rain also expected to
gradually spread into MS with time. Accretion rates of .06 in/3 hr
are possible in spots.

DISCUSSION...Strong low-level warm-air and moisture advection
continues to overspread the Lower MS Valley as a pronounced
mid-level trough approaches. Wintry mixed precipitation persists
across portions of southern into central AR, with several instances
of freezing rain noted by surface observations. Surface temperatures
hover around or just below the freezing mark over several locales,
and this should continue through the overnight hours, until the
primary precipitation band clears the region. While some 925-850 mb
warming is expected within the strong low-level WAA regime, surface
wet bulb temperatures below 0C should support continued freezing
rain tonight. A couple instances of .06 in/3 hr accretion rates may
occur within the heavier portions of the main precipitation band.
Freezing rain may develop into northern MS around or before 09Z, as
also shown by some of the 00Z HREF guidance.
