Areas affected...North-Central/Northeast KS...Southeast/East-Central
NE...Southwest/South-Central IA...Far Northwest MO

Concerning...Heavy snow 

Valid 251641Z - 252245Z

SUMMARY...Ongoing heavy snow across southeastern NE and
north-central/far northeast KS is expected to continue for next
several hours. Additionally, gradual eastward expansion of this
heavy snow into southwest IA and far northwest MO is anticipated.

DISCUSSION...Recent surface observations show numerous locations
across southeast NE and adjacent north-central KS reporting moderate
to heavy snow. Satellite and radar imagery show the dry slot is
currently moving through central KS, suggesting much of southeast NE
will remain within the band of heavy snow for at least the next
several hours. Additionally, with the shortwave trough approaching
the region, lift will likely intensify, resulting in increased
snowfall rates and the potential for up to 2" per hour (particularly
across far southeast NE). 

As the overall system moves northeastward, the area of heavy snow is
expected to do likewise, bringing snowfall rates over 1" per hour in
southwest/south-central IA and far northwest MO during the next
several hours. Once established, these high snowfall rates are
expected to last for 3+ hours.
