weather
Freezing rain Sunday afternoon to Monday morning.
What:
A long lasting period of freezing rain.
Ice accretion amounts of 5 to 10 mm.
When:
Beginning Sunday afternoon or evening through to Monday morning.
Additional information:
A rapidly intensifying low pressure system is expected to track over the Great Lakes. Freezing rain is expected to begin Sunday evening and persist through Monday morning before transitioning to rain showers or flurries. As temperatures are expected to be fairly close to the freezing mark, it is possible some areas will receive rain Sunday afternoon and evening.
There remains some uncertainty regarding the track of the low pressure system and as a result exact ice accretion amounts are somewhat uncertain.
Local utility outages are possible. Travel conditions are expected to be difficult. Ice covered surfaces are likely.
