Another rain/snow/wind event expected across the island Today/tonight/tomorrow..

Tuesday, November 13th 7:00am..  An area of high pressure is currently crossing the Maritimes and is giving the calm winds to the island. An area of low pressure has developed along the US southeast coast near Cape Hatteras. This feature will intensify into a noreaster today as it tracks NE towards the Maritimes. Clouds have already spread across the region and precip is expected to begin this afternoon in the form of snow but change over to rain as the temps rises. The storm itself is expected to move into the Bay of Fundy this evening then right across PEI just after midnight tonight, then into the southern Gulf headed towards Newfoundland tomorrow. morning. Rain and very strong winds will accompany this system tonight. The rain will end tonight after the storm moves through but very strong W-NW winds will continue all day tomorrow as well as a surge of very cold air. Onshore cloud and flurries will prevail tomorrow especially down east in these NW winds.  Expected flurries at times heavy and blowing/drifting snow especially in the morning. This activity will diminish later tomorrow as a ridge of high pressure builds in which will allow winds to drop off to calm Thursday night. On Friday we don it again. Another noreaster will develop off the US mid Atlantic coast and track NE. This time the track is a little further SE which should keep the Maritimes on the cold side resulting in a threat of snow rather than rain. The storm itself passes SE of NS vicinity Sable Island just after midnight Friday night then continues to move NE into Newfoundland by Saturday morning. Again this looks like a cold scenario so expecting snow with this system.  Skies clear later Saturday as high pressure approaches. Clouds and rain return later Sunday into MOnday with weak low pressure passing by to the north.

Precipitation.. Snow begins early this afternoon changing to rain by late afternoon then ending just after midnight tonight. Up west could see 5-10 cms snow, Queens and Kings, 2-5 cms. Rainfall amounts in the 10-15 mm range. Flurries/snow squalls possible early Thursday in the onshore NW winds especially for Kings county where additional accumulations are possible. Dry Thursday late afternoon through Friday morning. Snow begins near noon on Friday tapering to flurries before dawn on Saturday giving 10-15 cms. Showers on Sunday. More snow on MOnday and Tuesday as we are locked in a cold pattern.

Temperatures.. The region is locked in a cold pattern with just a couple of brief warm-ups. The first one tonight when temps climb to +10 just after midnight for a couple hours then fall by dawn tomorrow. The second warm-up will be on Sunday when temps return to normal for the afternoon. Next week is looking even colder as arctic air invades the Maritimes. Bundle up and get your property ready for winter.

Wind.. SE winds begin early this afternoon increasing to brisk this evening then shifting to SW-W after midnight tonight further increasing to strong with gusts to 90 KMH possible. These strong W-NW winds continue through Wednesday diminishing to calm by Thursday night into Friday morning. SE winds redevelop Friday noonish in advance of the next system.

Hazards.. Winter driving conditions for a few hours today beginning near noon. Wet driving conditions in rain tonight. Strong winds developing after midnight tonight resulting in more bridge restrictions on the Confederation Bridge which will most likely last well into tomorrow evening. Plan accordingly of driving if high sided vehicles. Could be snow squalls for eastern PEI during the day tomorrow in the onshore NW winds. Bitterly cold tomorrow as well with wind chills values near -15. Quiet Thursday evening into Friday morning. More snow Friday afternoon through Saturday.
