ROCHESTER, N.Y. – The temperature at the Rochester Airport today reached 90 degrees.  That is eighth time this season of 90 degrees or higher and it probably will not be the last.  What is more definitive is the chance of rain and that probability will be on the increase for the remainder of the weekend.  A combination of a low pressure system and a warm front now approaching from the west will increase the southwest flow of higher dew points and eventually some rainfall.  Expect increasing chances for showers and thunderstorms over the next 48 hours.  If the rain does not come down too heavy, this will make for some welcome rainfall for Western New York.

Tonight look for patchy clouds and just the chance of shower or thundershower later tonight.  It will be a muggy night with the low in the upper 60s.  Sunday will bring a few breaks of sunshine with an occasional shower and thunderstorm by later in the afternoon and evening.  At this point, it does not appear to be severe, but any storms could contain a heavy downpour and small hail.  Expect lots of humidity with the high temperature in the low to middle 80s.  Another few showers and thunderstorms are possible Sunday night and Monday. Tuesday any spotty thundershowers will come to an end as low pressure will slowly depart the area. This will take most of the wet weather out of Western New York by the middle of the week.

Wednesday and Thursday you can expect mostly sunny skies with much lower humidity.  Both days will bring high temperatures in the middle to upper 80s.
