.PREV DISCUSSION... /Issued 921 PM CST Thu Feb 14 2019/ 

..UPDATE...

DISCUSSION...
Cold front has moved through about the northern third of OK, with
surface temperatures in the lower/mid 30s near the KS border.
Based on recent HRRR/NAM output, going Winter Weather Advisory
looks to be in good shape. Some very light freezing rain/drizzle
may develop late tonight, although best chances look to hold off
until after 6-7 am. The northern half of the advisory, mainly from
Osage county east to Ottawa county, looks to be the favored area
for accumulating freezing rain/sleet Friday morning and into the
afternoon before precip tapers off.

Will continue to monitor, but no significant changes are needed 
to the forecast at this time.
