Fair weather will be the case overnight with mainly clear skies and comfortable temperatures, in the low to mid-50s for areas in the valleys, to the upper-50s and low-60s elsewhere across western New York.
A weakening frontal boundary will brush the area from the north and west Wednesday morning, keeping the chance for a few isolated inland rain showers during the afternoon. Shower coverage will be very spotty, but most locations across the viewing area will remain dry with plenty of sunshine and comfortable temperatures, in the 70s.
The remainder of the week should be mainly rain-free with plenty of sunshine for most days. We have another chance of seeing an isolated shower or thunderstorm develop Thursday afternoon. Readings edge up a bit as becomes warmer toward the end of the week. At this early point in the week, next weekend looks pretty good, mostly sunny Saturday, partly sunny Sunday along with increasing heat, humidity. Shower chances increase into the start of the next work week.
