Snow today then turning bitterly cold tonight/tomorrow across PEI.

Thursday, February 13th 7:00am… A couple things happening today weather wise for the Maritimes. 1ST, A low pressure system located along the US mid Atlantic coast this morning will intensify as it tracks NE passing SE of NS this afternoon. Light snow will quickly spread across the island as this system approaches. 2nd, A strong cold front located in a NE-SW fashion is currently dropping southward into northern NB. This feature will move across PEI late this afternoon. The coldest air of this winter season will then pour in behind this front making for a bitterly cold Friday into Saturday morning as Cold arctic high pressure builds in from the NW. Cloud and few flurries should continue tomorrow especially down east  in the onshore NW winds. These winds will also make for low wind chill values. Skies should clear tomorrow night as the high pressure system passes by to the south which will shift the winds to more westerly ending the onshore activity. Saturday starts out clear and very cold but temps begins to moderate under a SW wind. Clouds invade later Saturday as a warm front begins to approach with some flurries possible. Another cold front crosses Monday afternoon with more cloud and few flurries. Sunshine on Tuesday under high pressure. Watching a weather system moving NE out of the Great Lakes on Wednesday but still way too early for details as the models are quite different at this time.

Precipitation… Snow begins mid morning today tapering to flurries early evening. Southeast corner of the island (Murray Harbour) looks to receive the most being closer to storm track with 6-7 cms possible dropping to 3-5 cms across Charlottetown, 1-2 cms for Summerside and just a trace up west. Flurries possible on Friday, again Sunday and Monday.

Temperatures… Temps should climb to 0 today. Get ready fro the coldest air of the season which will pour in late this afternoon on brisk NW winds. The core of the cold air near dawn Saturday morning. Temps then slowly begin to moderate on Saturday but staying below normal. Sunday and MOnday should be back to slightly above normal. A cold Tuesday then need to watch the Great Lakes system on Wednesday. Could be warm enough for rain.

Wind… Light SW winds now but will shift to brisk NW mid-late afternoon as the cold front moves SE across the Island. Light-brisk NW winds continue into tomorrow shifting to light SW on Saturday.

Hazards… Light Snow today. light-brisk winds will also give local blowing/drifting snow especially in rural areas. Any wet/slushy surfaces will freeze solid late this afternoon. More importantly will be the blast of cold arctic air and bitterly cold wind chill values on tomorrow morning for those kids walking to school. Saturday morning will most likely be the coldest morning of this winter season.

Watches/Warnings… None for PEI at this time.
