Sunday, November 18th, 8:00am.. An area of high pressure centered over Montreal this morning is drifting eastward and will pass south of the Martimes this evening. Generally clear skies and light winds will accompany this feature. Skies will cloud over after midnight tonight as a first in a series of weather disturbances approaches the Maritimes. This first system moves along the Atlantic coast of NS later tomorrow into Tuesday morning bringing a mix of rain and snow across the island. The Second system passes south of NS on Tuesday nigh into Wednesday bringing another threat of rain and/or snow. The third system moves westward into the Gulf of Saint Lawrence Thursday night into Friday morning with what looks to be a snow event especially for eastern PEI. Looks like cloudy unsettled 5 days ahead with either rain and/or snow depending on temperatures. Things quiet down for the weekend with high pressure in control.
Precipitation.. Snow begins near noon tomorrow could possibly change to rain for a few hours then back to snow before ending near midnight. 2-5 cms snow and 5 mms rain. Wednesday looks like a bigger mess with 10-15 cms snow possible beginning Tuesday afternoon ending Wednesday afternoon. Left over flurries on Thursday becoming periods of snow again Thursday night as the 3rd systems approaches. Still need more data for amounts here but looks like eastern PEI will see the most.
Temperatures.. Normal afternoon high temperatures for this time of year of +5. We won’t see +5 for at least another week-10 days.. So below normal temps continue but no bitterly cold. Looks like the coldest day of the week will be Thursday-Friday.
Wind.. Don’t see a low of wind until the Thursday night system moves through.
Hazards.. Hazardous driving condition sin any snow over the next 5 days. Snow should be fairly wet and compact. Winds remain light so blowing/drifting snow not really a concern until maybe Thursday evening.
