Thunderstorms late today - cool dry weekend

It is another beautiful morning here on L'Ile Perrot with sunshine and warm temperatures for mid-September. We managed another warm 80F plus day on Thursday to add to what has been just one spectacular summer. The high in Montreal was 29C (85F). We need rain however and we should receive a little later today. A cold front is to our west this morning over central Ontario and it should arrive by late evening. Before that we can expect another sunny, warm day with highs near 28C (83F). Winds will be on the increase out of the southwest as the front approaches and should gust to 50km/h in the St. Lawrence Valley. The front will arrive with a burst of showers and perhaps a thunderstorm from this evening into the wee hours of the morning. A few lingering showers may be around to start the weekend, but otherwise look for dry weather but much cooler with highs of 15 to 18C (60-65F) this weekend. The sunshine will last into Monday with warming temperatures into the 20's.
