MD 0027 CONCERNING WINTER MIXED PRECIPITATION FOR PORTIONS OF CENTRAL ARKANSAS
Mesoscale Discussion 0027
NWS Storm Prediction Center Norman OK
0527 PM CST Thu Jan 09 2025
Areas affected...portions of central Arkansas
Concerning...Winter mixed precipitation
Valid 092327Z - 100330Z
SUMMARY...Mixed wintry precipitation should continue into the
evening hours, with heavier snow likely later tonight.
DISCUSSION...700 mb warm-air and moisture advection is increasing
across AR with the approach of the mid-level trough, which is
currently progressing across the southern Plains. The low-level
warm-air/moisture advection regime is supporting heavier
precipitation across central AR, as shown by both MRMS mosaic and
KLZK regional radar imagery. Bright banding is ongoing across
southwestern into central AR, with reports of heavier snow rates
just north of the bright banding area. RAP forecast soundings shows
temperatures within the 850-700 mb layer hovering around the
freezing mark, which will continue to support a mix of snow, sleet,
and perhaps some freezing rain over the next few hours. With time,
cooling within this layer will promote primarily heavy snow,
including 1+ inch/hr rates, later this evening.
