Tuesday Sept 1st 6:40am.. Good morning and welcome to the first day of September and the 1st day of meteorological fall. A low pressure system tracked across the northern Gulf overnight and is now located just west of Newfoundland. A cold front extended SW from this low and also crossed the island yesterday evening and that was responsible for the band of heavy thundershowers which rolled through. Skies should clear this morning as the low moves further away and a ridge of high pressure builds in. This feature will cross the island this evening with clear skies and the coolest temperatures we have seen in quite a while. Another cold front is then expected to sweep across the region Wednesday afternoon with another band of showers and possible thundershowers. High pressure returns for Thursday and should remain in place over the Maritimes through Saturday. Looks like a cold front will be trying to drop down from the north on Sunday spreading some cloud and showers.
Precipitation.. That heavy rain yesterday evening was a surprise. I recorded 17.2 mms here in the New Haven area. Could still be a stray showers this morning but a drying trend is in store today. Dry again tomorrow then showers beginning Wednesday afternoon. Dry for Thursday through Saturday then watching another round of showers spreading across the island during the day on Sunday.
Temperatures.. Today and tonight will be cool. The heat returns on Wednesday then a slight cool down for Thursday and Friday. Temps at or above normal into the weekend.
Wind..Diminishing NW winds today dropping off to calm this evening then shifting to the south after midnight. Light SW winds tomorrow shifting to the west behind the cold front later Wednesday. Light northerlies for Thursday and Friday turning to westerlies on the weekend.
Thunderstorms.. The storms yesterday evening were a real surprise as the front was expected to be weak but i think the low pressure system tracked a little further south than expected. The storms did not extend much further south than northern NS. The next chance of thunder appears to be on Wednesday.
Watches/warnings.. None for PEI at this time.
Today.. Cloudy with a slight chance of a showers this morning then clearing, light-brisk north winds, highs 16
