A few showers may interrupt the sunshine Friday and Saturday as heat and humidity push north.
Friday & Saturday Rain Chances
Both Friday and Saturday will have some low chances for rain in the Finger Lakes.
Radar Friday morning shows an area of rain over eastern New York associated with an area low pressure that is riding up along the Eastern Seaboard. While one or two showers over central New York may be possible this morning, that rain should be pulling away with little to no impact in the Finger Lakes.
A second area of some scattered showers over Michigan is dropping southeast. These are associated with a weak disturbance passing through the Great Lakes.
This disturbance should dissipate today, but a couple of widely scattered showers may still try to develop this afternoon, particularly across the western portions of the region.
Next, a surge of warm air aloft will make its way towards the Finger Lakes early Saturday. Again, a few widely scattered showers or a thunderstorm will be possible.
The best chance for precipitation Saturday will be early in the morning and again during the late afternoon hours.
Many areas will escape Friday and Saturday with little to no precipitation. Only a few isolated areas may see more than a couple hundreths of an inch of rain.
Outside of the rain showers, breaks of sunshine are likely both Friday and Saturday.
Temperatures Friday and Saturday will be near normal, with highs in the mid and upper 70s.
Heat and Humidity Arrive Sunday
A very warm and humid air mass will start to move into the Finger Lakes Saturday night. A steady southwest wind will continue to pump warm air into the region, even after sunset, resulting in tempreatures in the 60s Saturday night.
This will get temperatures off to a running start Sunday morning. Sunny skies will combine with the southwest wind to raise temperatures in a hurry.
By noon, many areas will already be in the 80s. Highs Sunday should reach the mid and upper 80s with a few places pushing towards 90 degrees.
Monday will be a couple degrees warmer, with mostly upper 80s and a few low 90s in the typically warmer locations between Rochester and Syracuse.
Along with the heat, the humidity will increase as well. Dewpoints will rise well into the 60s, sending the heat index into the low 90s.
The weather Tuesday and Wednesday is a bit less certain at this point as a cold front will try to work in from the north. This could lead to some showers and storms on Tuesday and/or Wednesday which could help keep temperatures in the 80s.
If the front clears the region, temperatures will fall back towards the upper 70s and low 80s, but with much lower humidity.
Temperatures will likely remain summery through most of next week with 80s commonplace.
