Cool weekend expected across PEI..

Saturday, September 8th 7:45am… A weak cold front is currently sweeping across the island. Not much inn the way of weather except for some cloud and a wind shift to the NW. Cooler air will filter in behind this front for the weekend as high pressure dominates the Maritimes. This cooler air will be unstable meaning daytime heating will result in afternoon cloud build-ups with possible showers both today and tomorrow. The area of high pressure will crest over the region Monday morning then drift SE. Clouds will then begin to increase as the remnants of Tropical system “Gorden” approach from the lower Great Lakes with rain developing by noon Tuesday. Significant rain is possible depending in the exact track this system takes across the region. Gorden moves east on Wednesday but still could be some cloud and showers around. High pressure builds in for Thursday and Friday.

Precipitation..  Chance of an isolated shower both today and tomorrow in the cooler air. Rain from “Gorden” begins near noon on Tuesday ending Wednesday morning. Significant rain is expected but too early to into exact numbers right now but anticipate that rainfall warnings maybe required.

Temperatures.. The coolest air of the season will effect the Maritimes this weekend into Monday. Tuesday will start to see a warm-up as winds turn southerly and Gorden approaches. Above normal Wednesday Thursday and Friday.

Wind.. Light-brisk NW winds today and tomorrow dropping off to calm Sunday night into Monday. Light SE winds begin to develop Monday afternoon increase to brisk on Tuesday.

Tropical systems.. As already mentioned, the remnants of Gorden will pass through the Maritimes on Tuesday with heavy rains. Florence now located in the central Tropical Atlantic weakened into a tropical storm yesterday due to unfavorable environment but conditions are improving now and expect the storm to restrengthen back to hurricane status. Florence is moving generally westward and with an increasing chance of striking the US east coast vicinity North Carolina Thursday night but this is far from certain. This storm may rewrite history as no storm ( from what I hear/search)  in the past has impacted the east coast from the position that Florence is in right now. All storms in the past have turned away from North America and back out into the Atlantic. Interesting….

Hazards.. Fairly quiet except for the chance of an isolated shower which could give temporary wet driving conditions.. This time of year when cooler air invades there is always the risk of waterspouts over the Gulf/Strait but think the winds maybe a bit too strong. Better chance tomorrow as winds drop off a bit.

Watches/warnings.. None for PEI at this time but anticipate rainfall warnings maybe required for Tuesday.
