Early Week Weather
An area of low pressure will meander through the region today with some scattered showers.
Most of the precipitation this morning is off to the east of the Finger Lakes as some dry air wraps into the low pressure system. There are even some breaks in the clouds and fog across the region, and glimpses of sunshine will continue to be possible throughout the day.
A stray shower cannot be ruled out here or there, but the best chance for scattered showers will come during the mid to late afternoon and into the overnight. A few rumbles of thunder will also be possible.
Individual showers should be relatively short-lived, but there should be enough of them that most areas should see some rain this afternoon or evening.
Winds will increase from the northwest as a secondary low develops along the Mid-Atlantic coast and moves northward toward New England. Wind speeds may approach 10 mph at times.
Afternoon highs will top out in the upper 60s to around 70 degrees. Higher elevations will stick to the mid 60s. This is close to, but just a degree or two under, the climatological average highs for today.
Nighttime temperatures will also be close to average with lows in the low and mid 50s. A few valleys in the western Southern Tier may slip just below 50 degrees.
Clouds and a few showers or some drizzle will linger into early Tuesday morning, but sunshine should increase for most areas before noon. Skies will continue to clear, leaving mostly sunny skies for much of the afternoon.
Wind will remain out of the northwest and will be blustery in the morning with speeds of 10-15 mph. The wind speed should decrease during the afternoon.
Temperatures will be at their low point for the week with highs in the mid and upper 60s. Widespread 40s are likely Tuesday night into early Wednesday, though a few lakeshore areas may stay near 50 degrees. Most of the southern half of the region will see mid 40s with upper 40s to the north.
Dry Into the Weekend
High pressure will be in firm control of our weather for the middle and end of the week.
Wednesday will be mostly sunny with a light northwest wind. Temperatures will warm quickly during the morning, reaching an afternoon high in the upper 60s to around 70 degrees.
Clear skies and calm winds Wednesday night will send temperatures back into the mid and upper 40s for Thursday morning. However, the same pattern will unfold, with quickly rising temperatures under sunny skies.
Thursday afternoon may have a couple of stray clouds but will generally be mostly sunny again. Highs will add on another degree or two, with highs mostly near or just above 70 degrees, except in higher elevations.
Thursday night will also be slightly warmer with more areas staying near 50 degrees and fewer areas slipping into the mid 40s.
Friday afternoon will be the warm point of the week with highs in the low and mid 70s. Skies will be a mix of sun and clouds with a steady but light southeast wind.
The weather should become more unsettled this weekend, though how it unfolds is still uncertain. Saturday is the more likely of the two days to remain dry, though there may be plenty of clouds in the area.
Sunday will likely have at least some showers with a chance for steadier rain. Temperatures will slip back a few degrees during the daytime hours but will be warmer at night, thanks to the clouds and potential for rain.
As we head toward the end of September, unsettled weather looks possible with temperatures near or below average.
