First Alert Weather: Change of seasons will bring a big change in the weather

ROCHESTER, N.Y. (WHEC) — High pressure centered over the eastern Great Lakes gave us a “Chamber of Commerce” type of day for Western New York.

The combination of bright sunshine, lower humidity and comfortable temperatures is usually considered ideal weather conditions. This nice weather will translate into a pleasant evening. Look for clear, moonlit skies with the temperature cooling to near 50° for the overnight.

Once again there could be some patchy fog developing late tonight. The next 48 hours will bring some nice late summer weather. The last full day of the summer season is Tuesday and we expect above normal temperatures. In fact, both Monday and Tuesday should bring partial sunshine and temperatures that are near 80°.

Looking ahead to mid-week, the chance of rain will be on the increase. A cold front will be approaching Western New York with an associated low-pressure system. As a result, showers will be likely late Wednesday into Thursday with the probability of precipitation running between 60 to 70%. This will usher in some much cooler weather as the temperature slides into the 60s and 50s. This may be good timing for the official start of the fall season. The autumnal equinox arrives on Wednesday at 3:21 p.m.
