Rain is likely this weekend, though the bulk of Saturday’s may hold off until after sunset, especially in more eastern areas. Rain and thunder will increase Saturday night into Sunday morning, with spotty showers persisting through Sunday afternoon, Monday, and perhaps even into Tuesday. Temperatures will hold in the 70s, except for Monday, when many areas peak in the upper 60s.
Published Friday, August 21
Friday
What: Sun and clouds.
Quiet weather is expected on Friday with sunny skies and a few small clouds. Areas of fog early will burn off by the mid-morning. Temperatures will be in the mid and locally upper 70s with dewpoints in the 50s. Winds will be light and variable, if not outright calm. Mostly clear nighttime skies are expected with some patchy river valley fog. Lows will mainly be in the mid 50s.
Saturday
What: Some late showers and storms
Saturday will likely start out with some sun before clouds gradually increase through the morning. The afternoon is looking less rainy now as the models continue to fine tune the evolution of the incoming weather system. There will still be a few scattered showers and storms about in the afternoon, but they will be most likely late in the afternoon and over areas west of Seneca Lake. The overall coverage looks less during the day and many areas, even in the west, may get through the daytime hours mostly or completely dry.
Rain and thunder will become more widespread in the evening and through the overnight as the weather system slowly moves in from the west.
Flooding and severe weather are not expected, but some isolated downpours or gusty winds will be possible.
Temperatures will range from the mid 70s across the Southern Tier to around 80 degrees along and north of the Thruway. Dewpoints will be in the low 60s, and winds will be from the south around 10 mph. Overnight lows will reach the low 60s.
Sunday
What: Scattered showers
The area of rain from Saturday night may still be working through the area early Sunday. Some strengthening could even occur over the eastern Finger Lakes with some thundery downpours. Once this more widespread areas of precipitation moves out, the rest of the day will have spotty showers and a few isolated thunderstorms, but also plenty of dry time.
Winds will be from the southwest at 10-15 mph, with the strongest winds to the west. Afternoon highs will reach the mid 70s with dewpoints in the mid 60s.
A few stray showers cannot be ruled out Sunday night. It will be cooler, with lows in the mid 50s.
Monday
What: Scattered showers.
Cool air will build in on Monday. Daytime high temperatures will generally top out in the upper 60s, though a few of the typically warmer pockets will still reach 70 degrees. Southwest and west winds will blow at 10-15 mph. This set up will lead to some slight lake effect influences off Lake Erie, leading to an increased chance in rain showers across the northwestern half of the region. Showers will also be possible to the southeast, but should be spottier.
Tuesday
What: Sun and clouds. A few showers.
Tuesday should have a mix of sun and clouds with a few lingering pop up showers. Highs will be in the low and mid 70s with dewpoints in the 50s. Winds will be from the northwest at around or slightly over 10 mph.
Wednesday
What: Sun and clouds
Wednesday should be dry between weather systems with a mix of sun and clouds. Temperatures should reach the mid 70s with a light south wind or calm winds.
Thursday
What: Sun and clouds
Another weather system will approach the area late next week, but current projections hold the rain off until after Thursday. If that holds true, it will be a day with sun and clouds, though perhaps the clouds will increase and take over late. Highs should be in the upper half of the 70s.
Next Weekend
Friday seems to be the prime target for rain late next week, though showers lingering into the weekend will certainly be possible. Temperatures will remain about where they have been in the 70s. The weather is too uncertain to draw any real conclusions as we head into the first week of September, with a wide spread in the models showing for both temperature and days with precipitation.
