More snow expected tonight across PEI. Turning much colder tomorrow.

Wednesday, November 21st 6:45am.. A low pressure system racked NE along the coast of NS and is now located in the Cabot Strait. This system brought snow and relatively mild temps to the island yesterday evening and overnight but precip is now tapering off the the system pulls away. The system will now intensify as it moves over Newfoundland resulting in a brisk NW wind developing later this evening and overnight. Another low pressure system in southern Quebec now will move eastward and is expected to the Maritimes tonight with more cloud and periods of snow. Brisk NW winds will develop in the wake of this system tomorrow which will usher in much colder air for tomorrow and Friday. This cold air over the opens waters of the Gulf will also result in onshore snow squalls and flurries. High pressure will pass south of the Martimes on Saturday/Sunday with sunshine and milder temperatures. Clouds return on MOnday as the next weatehr maker moves up the coast but the models are inconstant on how close this system comes to the Maritimes so on Tuesday/Wednesday which will also impact the type if any of precip so will need to wait a couple more days for the picture to become clearer.

Precipitation.. Periods of snow is tapering off now. Few flurries today becoming periods of snow again tonight as the next system approaches. The snow tapers back to flurries for Thursday morning which should then continue through Friday afternoon especially eastern half of the island. Snow fall amounts of 5-10 cms tonight then another 2-5 cms in flurries later Thursday into Friday. Basically dry for Saturday and Sunday. Sowers or flurries for later Monday into Tuesday.

Temperatures..  Slightly below normal today turning well below normal after midnight tonight which then continues through Thursday and Friday. Temps then moderate back to slightly below normal for the weekend. Normal conditions beginning Tuesday.

Wind.. light-brisk W-NW winds today will increase to brisk-strong after midnight tonight and continue through the day tomorrow and Friday. Brisk west winds on Saturday drop off to calm Saturday night then becoming light easterly on Sunday.

Hazards.. Snow covered roads today but relatively mild temps should allow salt and sand to work. More snow this evening. Turning much colder after midnight tonight along with brisk winds will result in blowing and drifting snow developing. Reduced visibility in flurries and snow squalls fro eastern PEI tomorrow.
