It was yet another 90 degree day in Syracuse today, the 26th day this year (2nd most all-time). In spite of this heat and an approaching cold front, our chances for any thunderstorms this evening look pretty low at this point. The best energy in the upper atmosphere is well up across Canada plus very warm air aloft around 10,000 feet are hindering any thunderstorm development. We’ll keep a slight chance of thunderstorms well to our northeast across the Adirondacks and St. Lawrence River valley until the front moves through later this evening.
Once the cold front moves through we are in good shape for much, if not all, of the upcoming holiday weekend. By tomorrow morning a cooler and slightly drier air mass will move into central New York. This is going to return temperatures closer to 80s degrees. While this is still above normal for the first day September it will be much cooler than Friday’s 90s. With the cooler weather will come a good deal of sunshine.
Moisture begins to return to central New York Monday. With a cold front and the remnants of Isaac still to our west there won’t be a lot of forcing to turn this moisture into showers and storms. We are going to keep only a low chance for wet weather in the forecast for Labor Day afternoon. Most of the day will be rain-free.
Our best chance for showers and thunderstorms over the next 7 days will come Tuesday as the cold front we mentioned above moves through with a little help from some moisture from Isaac.
