High Pressure
A broad area of high pressure over the Great Lakes region will bring quiet and comfortable weather to the Finger Lakes today.
The day is starting off with some typical summertime valley fog in the usual places across the Southern Tier and Central New York this morning. The rest of the area is sunny, with just a few clouds here and there.
Fog should burn off during the mid-morning hours, with fair weather clouds forming by the late morning. The afternoon will have plenty of sunshine and mainly small, puffy, fair weather clouds.
There is only a very small chance for a brief spit of rain this afternoon, mainly over the higher elevations of the western Southern Tier. Any rain that manages to fall will be very light and will likely only last a few minutes at most.
Most of the wildfire smoke has also cleared out of the region and air quality should not be a concern for the near future.
Temperatures will range through the upper 70s and low 80s, with most places within a degree or two of 80 degrees. Dewpoints will be comfortable in the 50s. Winds will be near or under 5 mph from the north and northwest.
Skies will quickly clear as sunset approaches and will remain mostly clear overnight. Only a few thin clouds are expected around and after midnight.
Most areas should make it into the 50s tonight, with mid 50s across the southern half of the region with more valley fog, and upper 50s to near 60 degrees across the north and near lake shores.
Winds will swing around to the south Thursday morning as the high passes by to our east. While remaining light with speeds around 5 mph, the shift will be enough to bring warmer, more humid air back into the area.
Highs on Thursday should commonly reach the mid 80s with dewpoints around 60 degrees and rising late.
Skies will be a mix of sun and clouds. Late in the afternoon or early in the evening, some thunderstorms may fire up, though this remains uncertain.
Typical Summer Weather
Additional chances for rain and thunderstorms will continue Thursday night and into Friday. There remains a fair bit of uncertainty in how this all unfolds, so be sure to check back tomorrow morning for updates.
Regardless, the chances for severe weather and flooding appear to be low, though not quite zero, as this system moves through. Most areas should get through without any major issues.
A lingering shower will be possible Friday night and possibly into very early Saturday morning. That should be the extent of the precipitation chances for the weekend as another high pressure system moves in.
Saturday will be a bit cooler and breezier than we have seen in a while. Northwest winds will blow with speeds around 10 mph and gusts around 25 mph. This will hold temperatures to the low and mid 70s, despite plenty of sunshine.
By Sunday morning, the high pressure should be centered over southern New England. Temperatures should moderate back to near average, with highs Sunday pleasantly around 80 degrees. Both days this weekend will have dewpoints in the 50s.
The next system will move in sometime late Monday or early Tuesday. Temperatures will jump to the mid 80s on Monday ahead of the system with a few late showers or storms possible. Rain showers may linger into Tuesday before skies turn sunny with highs in the low 80s.
That should be the primary chance for rain during the weekdays next week with dry weather expected until the weekend.
Temperatures will most likely stick to the 80s, but become less certain late in the week, where there is a large spread of possibilities showing on the models. Overall, though, temperatures are more likely to go up than down.
