A disturbance will pass to the south this morning, but sunny skies should return by this afternoon.
A warm front to our south has an embedded disturbance riding along the frontal boundary. This disturbance has spread clouds and even a shower or two into the area this Tuesday morning. However, the disturbance will quickly move along to the east this morning. By the midday hours at the latest, most areas should see a return to sunny skies.
Winds on the back side of this small low pressure system will turn towards the northwest this afternoon. This will act to keep some building heat at bay for one more day. Still, with sunny skies and a lack of cold air to the northwest, temperatures will still be into the 80s for most areas. A few locations could even reach the upper 80s.

Skies tonight will be clear, but temperatures will mostly remain in the low and mid 60s. The wind will turn to the southwest, and the transportation of hot and somewhat humid air will begin.
Wednesday will be sunny and hot. Temperatures will rapidly rise in the morning and should be well into the 80s by midday. Afternoon highs will top out at or above 90 degrees for most of the Finger Lakes. Low to perhaps mid 90s may be possible in the typically warmer and urban areas. Dew points will mostly in the upper 50s and low 60s. This should tack on a couple of degrees for the heat index, but most people will not find it oppressively humid.
Scattered showers and thunderstorms will become possible on Thursday at almost any time of the day. These showers, and the associated cloud cover, should help keep temperatures in the 80s. Many areas will probably not see substantial rain on Thursday though. There will be a better chance for rain and thunder late Friday and possibly Saturday as a cold front moves through the region.
