Low Rain Chances
The transition from the hot and humid weather of late to a new pattern of cool, dry air is almost complete.
Some moisture left behind by the front and previous airmass is resulting in some cloud cover across portions of the region this morning. Lake Ontario is adding in a few clouds of its own and even a few stray lake effect showers southeast of the lake.
Clouds will continue through the morning and will probably increase in coverage for a time as the daytime heating kicks in.
Northwest winds will blow lightly through the day at around 5 mph. These winds will continue to pull dry air into the region. As a result, this afternoon, the cloud cover will start to diminish. By this evening, skies will be mostly clear.
With the clouds hanging tough into the early afternoon, highs will have a hard time reaching 80 degrees today for most areas. Many places will come close, though. Dewpoints, which have been around 70 degrees, will be in the mid and upper 50s today.
Tonight, temperatures will settle into the upper 50s and low 60s with a few cooler pockets. Valley fog will develop in the usual areas across the Southern Tier.
Another cold front will drop southeast through the area tomorrow, probably in the late morning or midday hours. A few scattered showers will develop along the front, especially for the southeastern quadrant of the region. However, most areas will probably not see rain, and even those that do will not see a significant amount.
Northwest winds will increase behind the front with speeds around 10 mph and gusts of 20-25 mph. Still, there should be a good deal of sunshine and temperatures will again be in the upper 70s to near 80 degrees.
Clear skies will return for the nighttime hours with temperatures a few degrees cooler than tonight. Most areas should end up in the 50s.
Weather Through the Weekend
High pressure will build in overhead on Friday. Skies will be mostly sunny with a few thin wisps of cirrus clouds and a couple of small fair weather cumulus clouds.
Winds will be almost from due north with speeds increasing through the morning to around 10 mph again. Gusts will be near or slightly over 25 mph.
Despite the ample sunshine, temperatures will be cooler on Friday. Most areas will struggle to even reach 75 degrees. The dewpoint will really drop and will only be in the low and mid 40s.
Friday night will again be clear and calm beneath the full moon. Nighttime temperatures will be a few degrees lower yet, with mostly low and mid 50s. A few pockets of upper 40s are probable.
Saturday will be similar to Friday, just with a few more fair weather clouds and afternoon highs a couple degrees warmer. North winds will remain but will be a bit lighter with speeds just over 5 mph.
The wind will be nearly calm and of a variable direction on Sunday. Skies will remain a mix of sun and clouds with highs crawling back into the mid and upper 70s. A few places may make it to 80 degrees.
Uncertainty increases early next week, but Monday should stay dry with sun and clouds. The nature of the clouds and the chances for any rain will influence the temperature, but highs are mostly likely to be in the upper 70s.
Some showers will be possible on Tuesday and throughout the rest of next week. It will not rain the whole time, and much of the rain will probably be light. However, the clouds and showers will continue to hold temperatures down with highs remaining in the 70s.
