Monday, August 21st 5:00pm.. An area of high pressure will slide by to the south of NS tonight, meanwhile a frontal trough lies east-west across the northern Gulf. This front will sag south tonight into early tomorrow giving some cloudy periods and chance of a shower/thundershower. A low pressure system located west of the Great Lakes will move NE tomorrow. This system, as it moves out of the Great Lakes will actually lift that front northward again later tomorrow. As the system tracks by to the north on Wednesday it will pull a cold front southeastward in it’s wake sweeping across PEI late Wednesday with more showers and thundershowers. This frontal passage will bring in some cooler air which for the end of the week. The cooler air will also be quite unstable with daytime heating so expecting afternoon cloud build-ups with hit and miss showers for Saturday and Sunday. The long range into early next week continues to hint at this instability with hit and miss afternoon showers into Monday.
Precipitation… Chance of a shower tonight especially up west. May even see a shower early tomorrow. Better chance of showers later Wednesday as that potent cold front sweeps across the island. Thursday and Friday looking dry but then getting into that instability for the weekend so chance of showers for Saturday through Monday.
Temperatures… Warm and muggy today through Thursday then that cooler air moves in for the weekend.
Wind.. Light-brisk SW winds through Wednesday diminishing to light on Thursday. Light and variable for the weekend.
Thunderstorms.. Slight chance of a thundershower up west tonight. Better chance on Wednesday.
Hazards.. Chance of a shower up west giving wet driving conditions.
