Ponca City. Storm total ice accumulations of 0.25 to 0.40 inches are
likely in the warned area. Impacts will be low to critical facilities
with isolated power interruptions possible. High impacts to travel
will occur.

– Freezing rain is expected to end in central Oklahoma Tuesday
morning, tapering off to freezing drizzle by Tuesday afternoon. All
precipitation should end in central Oklahoma by late Tuesday
afternoon. There may be a brief period of sleet and/or snow.

– Freezing rain will continue in eastern Oklahoma through Tuesday and
should end early Wednesday morning.

– Winds will be a concern for any areas with ice accumulations,
especially those in southeast Oklahoma. The time period most critical
for power outages appears to be early Tuesday morning through
Wednesday in southeast sections. If this continues into Wednesday
night will be a function of how much warming can occur on Wednesday.
