Areas affected...northwest KS...south-central NE
Concerning...Heavy snow
Valid 081339Z - 081745Z
SUMMARY...Heavy snowfall rates around 1 to 1.5 inches per hour are
possible through the morning.
DISCUSSION...A mesoscale band of heavier snowfall rates appears to
be developing across northwest KS on the northern periphery of a
warm conveyor belt located over the southern-central Great Plains.
Frontogenetic forcing for ascent is forecast to continue to
strengthen during the morning across western KS and eventually into
southern NE by late morning. The 12 UTC Dodge City raob showed a
moist profile and an above-freezing layer from the surface through
800 mb. A surface front is draped southwest to northeast from far
southwestern KS north-northeast into northwest KS (i.e., located to
the northwest of Dodge City). The colder airmass north of the front
will support snow as the precipitation type. Model guidance
indicates upwards of 0.10 to 0.15 inches per hour liquid-equivalent
precipitation across northwest KS this morning. As a result of
nearly 10:1 snow ratios, expecting 1 to 1.5 inches per hour (locally
heavier bursts are possible) as lift continues to strengthen during
the morning.
