MD 0060 CONCERNING FREEZING RAIN FOR FAR NORTHEAST KS INTO NORTHERN MO AND CENTRAL IL
Mesoscale Discussion 0060
NWS Storm Prediction Center Norman OK
0945 AM CST Fri Jan 17 2020
Areas affected...far northeast KS into northern MO and central IL
Concerning...Freezing rain
Valid 171545Z - 172145Z
SUMMARY...Freezing rain and sleet will continue to lift northeast
across northern MO into central IL through the afternoon hours.
DISCUSSION...Freezing rain, with some areas reporting sleet as well,
extended along the I-70 corridor from the Kansas City metro area to
St. Louis this as of 1530z. Across southwest MO/southeast KS,
temperatures are beginning to climb above freezing in continued
strong warm advection regime. As precipitation continue to spread
northeast across northern MO into central OK, periods of freezing
rain and sleet will continue into this afternoon. Surface
temperatures across the MCD area are generally in the mid 20s to
near 30 degrees with forecast thermodynamic profiles showing
continued support for freezing rain and sleep through much of the
day. Surface temperatures will slowly warm from south to north, with
the freezing line expected to be north of the I-70 corridor by 21z,
allowing frozen precip types to transition to rain. Precipitation
rates have been as high as 0.10 in/hr per Local Storm Reports from
WFO Springfield MO. Rates will mostly be lighter, at a few
hundredths of an inch per hr, though this seems like a reasonable
maximum rate in brief heavier showers.
