Also Plenty of Dry Time

A couple of small disturbances will pass through the Finger Lakes over the course of the Labor Day Weekend, bringing some showers into the area.

These features are still far from the Finger Lakes today, though, and our weather will be dominated by the northwesterly flow that continues between low pressure associated with the remains of Ida and high pressure building into the Great Lakes.

The wind today will not be as blustery as yesterday, with top gusts near or just over 20 mph.

Still, a narrow belt of moisture remains over our area, leading to widespread cloudiness and a few spits of drizzle. This will persist through much of the day until dry air moves in late. A little sunshine will come out for the late afternoon.

The clouds and winds will again hold temperatures mostly below 70 degrees. The best chances for hitting 70 will be in Monroe, Wayne, and northern Livingston, Ontario, and Seneca counties. Most of the southern half of the region and the hills of Central New York will stick to the mid 60s.

Partly cloudy skies tonight will allow temperatures to fall back into the 50s. The typically cooler areas in the southern half of the region will be in the low 50s with a few pockets of upper 40s possible. Further north, mid 50s will be common.

High pressure will slide through on Saturday, leading to a good deal of sunshine mixing with some fair weather clouds. Winds will turn to the south as the high presses east, giving highs a boost into the mid 70s.

Showers Increase

The first batch of showers will move in during the predawn hours Sunday morning. These will be light, but most areas should see a little rain. Most of Sunday morning and early afternoon should then be dry. Temperatures will again rise into the mid 70s.

During the latter half of the afternoon, additional scattered showers and a few thunderstorms will develop. Most areas will not see a thunderstorm, but light showers will be common. No severe weather or flooding is expected from any storms that develop.

Another dry period is expected Sunday night and into early Monday morning. Clouds and south winds will keep overnight temperatures in the upper 50s.

Rain will then move in during the mid to late morning hours. Given the early timing, thunderstorms will be less likely but still possible. A few showers may linger into the early afternoon, but most of the afternoon should be dry.

Winds will become blustery from the west with speeds of 10-15 mph and gusts of 35-40 mph. Cooler air will move in, keeping highs around 70 degrees.

Tuesday will be another dry day with temperatures bouncing back to the mid 70s. Another front will move through on Wednesday with additional showers and storms, sending highs back to around 70 for Thursday with a few showers.

An early look at next weekend shows a front possible at some point, but most of the weekend remaining dry. Temperatures may get a slight boost ahead of the front and could push toward 80 degrees.
