MD 0240 CONCERNING HEAVY SNOW FOR PORTIONS OF CENTRAL AND NORTHERN ARKANSAS
Mesoscale Discussion 0240
NWS Storm Prediction Center Norman OK
0444 PM CST Fri Mar 11 2022
Areas affected...Portions of central and northern Arkansas
Concerning...Heavy snow
Valid 112244Z - 120145Z
SUMMARY...Though localized, mesoscale snow bands will continue this
evening and be capable of producing snowfall rates near to just
above 1 inch and hour in parts of central and northern Arkansas.
Some of this activity may reach into parts of southern Arkansas
later this evening as temperatures cool below freezing eventually.
DISCUSSION...KLZK radar imagery shows highly banded reflectivity
structures. The strongest of these bands have shown 30-35 dBZ echoes
and have produced heavy snow reports from west-central Arkansas into
northeastern Arkansas. This region will stay within favorable
mid-level frontogentic zone as well as within the right entrance of
the upper level jet for the next 3-4 hours. These mesoscale bands
can be expected to continue this evening leading to the potential
for heavy, but localized, snowfall rates. Warmer temperatures exist
in southern Arkansas, but continued cold air advection and diabatic
cooling from precipitation should lead to a change over to snow and
potentially similar banding later this evening.
