Snow/rain expected today/tonight across PEI..

Tuesday, November 20th 6:30am.. A developing low pressure system located just south of Long Island this morning will track NE passing along the coast of NS to be located near Halifax just after midnight tonight then in the Cabot Strait by tomorrow morning. Snow from this system will begin mid/late afternoon today and change over to rain across eastern half of the island then back to snow before ending near dawn tomorrow. A ridge of high pressure briefly builds in Wednesday evening with partial clearing then Another area of low pressure moves across the region on Thursday morning with more light snow. This system moves east later Thursday but very cold air for this time of year will invade the island. Ti scold air will be very unstable over the relative warmer waters of the Gulf setting the stage for snow squalls where these northerly winds blow on shore. This activity will taper off on Friday as the winds change direction and becomes more westerly. A large area of high pressure passes south of the region Saturday night which should give quiet weather to the island for the Friday-Monday Time frame. Watching a potential system on Tuesday.
