High Pressure Overhead
A large area of high pressure will drift through the Finger Lakes today, keeping our weather quiet, albeit smokey.
The wildfire smoke that originated in Oregon and Washington is widespread across the northern half of the country and will continue to filter our sunshine through tomorrow.
There are no health concerns from the smoke, as it is locked high up in the atmosphere. You have to go all the way to western Montana and northern Idaho before the air quality is unhealthy due to smoke.
With the high overhead, there should be few clouds today and no rain.
Temperatures are very chilly to start, with widespread temperatures in the 30s and low 40s. These temperatures will start to come up as the high moves east and winds turn to the south. Look for afternoon highs today mostly in the upper 60s, but with locally warmer and cooler temperatures based on geography.
Wind speeds will be near or under 5 mph today before building to 5-10 mph tonight, still from the south.
The wind will prevent temperatures from getting nearly as cold tonight with overnight lows mostly in the low to mid 50s, but with a few pockets of upper 40s.
Wednesday will be like today with smoke filtered sunshine and little else. South winds will be around 10 mph and will push highs into the upper 70s and low 80s.
Cold Front Thursday
Clouds will increase Wednesday night ahead of a cold front. Temperatures will remain in the mid and upper 50s Wednesday night thanks to the clouds and continuing south wind.
The front will move through early Thursday morning. Unfortunately, rainfall with the front will be scarce and light.
Sunshine will mix with the clouds on Thursday. With north winds and our air being sourced from Canada, the wildfire smoke should be swept away with the front and blue skies will return.
Temperatures on Thursday will peak in the mid to upper 60s. Widespread 40s and a few pockets of 30s are expected by Friday morning underneath clear skies.
Thin clouds will build in from the south on Friday on the fringe edge of Hurricane Sally. No rain is expected, though a few of the European model ensembles have started to show that as a possibility late Friday into early Saturday. At this time, though, it seems very unlikely that it will come to fruition.
Instead, more quiet, cool weather is ahead. Friday should see highs in the mid 60s, but Saturday will only reach the low 60s and Sunday may stick in the 50s. Even Monday could struggle to reach 60 degrees before temperatures start to rebound for the middle of next week.
Morning lows will also be cold, especially Monday and Tuesday, when widespread 30s and frost will be possible.
Sunshine and dry conditions are likely all through the weekend and much of next week
