To assist you in any planning, I’ve tried to summarize the timeline of events and potential  impacts for a few communities:

Halifax: snow starts around 3pm.  Some low evening visibilities in gusty east winds with 15cm expected.

 Snow changes to freezing rain/ice pellets mid-evening (say 9pm).  After midnight expect rain and times heavy giving 40mm that ends before dawn.  Turns colder and clears with gusty northwest winds Tuesday

Impacts: poor driving rush hour into evening.  Possible outages and airline cancellations late evening from freezing rain.  Local flooding and slippery back roads from rain overnight and in morning.  I will shovel this evening to minimize slush… but taking a risk if it doesn’t turn to rain, I’ll have a slippery mess.

Sydney: snow starts around 7pm.  Some low visibilities in gusty east winds with 10-15cm expected. Snow changes to freezing rain/ice pellets after midnight. By 5am expect rain and times heavy (35mm) that tapers to showers/flurries before noon.  Turns colder and clears with gusty northwest winds on Tuesday afternoon.

Impacts: poor visibility for driving in evening, very slippery overnight.  Possible outages overnight from freezing rain.  Local flooding and slippery back roads from rain in the morning.

 

Charlottetown: snow starts around 6pm.  Low visibilities in gusty east winds with 25-35cm expected. Snow mixes with ice pellets after midnight improving visibility a bit..  A brief period of low visibilities in snow and strong northwest winds in the morning then tapering to flurries and turning colder with gusty northwest winds.

Southern NB: snow starts around 3pm and tapers to flurries around dawn Tuesday. Extensive low visibilities in strong northeast winds with 25 to 45cm expected.   Turns colder and clears with gusty northwest winds on Tuesday.

Impacts: poor driving at rush hour and all night.  Heavy accumulations of snow  and strong winds impacting all travel.  Strong winds may cause some outages.  School closures , morning flight cancelations and some business closures. Gradual return to “normal” during clean-up on Tuesday,
