Prince Edward Island Blizzard Watch
#peistorm Storm system out of the US is on route to Prince Edward Island for Tuesday (January 24th, 2017) A wintery mix of rain, freezing rain and ice pellets is expected across the province. In addition, strong wind gusts are expected across the province.
A deepening area of low pressure will be moving up the Eastern Seaboard towards the Maritimes Tuesday. At the same time, an elongated and persistent area of high pressure (centred over Newfoundland and Labrador) will deliver a colder and more dense airmass to the surface. Setting the stage for a tight pressure gradient (bringing strong easterly winds), and a mixed bag of precipitation. The north-west quadrant of this low will bring a mix of rain, freezing rain, ice pellets and snow across New Brunswick, and freezing rain for a period before switching to rain in Prince Edward Island.
A mix of freezing rain and ice pellets will move into Southern portions of Prince Edward Island between 9-11pm. A couple hours of freezing rain and/or ice pellets is expected before a change over to rain. Freezing rain may persist for a few hours, ending in the early morning Wednesday. Local freezing rain amounts of a trace - 2mm are expected in most areas of P.E.I. with a small exception in far eastern sections of the island. Brisk easterly winds gusting 40-70km/h will accompany the storm as it moves through. Additionally, up to 20-35mm of rain is expected through Wednesday.
There is some model uncertainly in regards to how the cold air and warm air from this system will interact and sections of eastern P.E.I. may also see a brief period of freezing rain before quickly switching to rain.
Ice accretion will be fairly limited.
More details asap.
