Just a few stray showers through Saturday

Weak Fronts

A southeasterly flow of air is bringing moisture back into the region, but there will be little in the atmosphere to tap into the increasing humidity.

An area of low clouds has also moved into parts of the area thanks to the southeast winds that developed overnight. These clouds are mostly over the southern and eastern Finger Lakes, while areas further northwest are starting Friday with mostly clear skies.

The clouds will continue this morning and may expand even further north and west. Then, this afternoon, there should be a general reduction in cloud cover as the low level moisture gets mixed up with drier air from higher in the atmosphere.

A stray shower cannot be ruled out this morning, but most areas will stay dry. Any showers that do develop will be very light and brief.

It will be a mild day today with highs mostly in the upper 70s. A few low 80s are likely along the I-90 corridor, and a few higher elevations will stick closer to 75 degrees. Dewpoints will be in the mid 60s.

A pair of weak cold fronts will move through around dawn Saturday and during the early afternoon. These will both have some scattered light showers. Some areas will probably miss out on seeing rain altogether. Breaks of sunshine between the showers and especially between the fronts will be possible.

Temperatures Saturday will reach the mid 70s during the early afternoon. A drop into the low 60s should take place shortly thereafter. Saturday should also end with clearing skies. Dewpoints will be in the mid 60s most of the day before dropping Saturday night.

Sunny and Dry

High pressure will build in Saturday night and will stick around for several days.

Sunday will be mostly sunny beneath the high, though some early morning fog is possible in the usual areas of the Southern Tier and Central New York.

A light north wind will set up behind the cold front Saturday, keeping highs on Sunday limited to around 70 degrees.

The wind will swing around to the southeast by Monday, leading to an increase in temperature. Look for highs in the mid and upper 70s. Dewpoints will remain comfortably in the 50s. Only a few small clouds are expected, if even that.

On Tuesday, thin clouds will start to move in from the west ahead of our next weather maker. There should still be plenty of sunshine and no rain will fall.

South winds will start to pick up with gusts on Tuesday around 25 mph.  Little change in temperature or humidity is expected compared to Monday.

Clouds will increase for Wednesday, but most of the daytime hours should stay dry. Rain will start to approach from the west late in the afternoon. Highs will mostly be in the low and mid 70s.

A slow moving area of heavy rain is likely Wednesday night and could linger into Thursday morning for eastern areas. Rainfall amounts of an inch or more seem likely, though it is too early to be certain.

Behind this front, temperatures will take a turn downward for an extended period of time. Even hitting 70 degrees may be a tall order for the rest of September starting next Thursday.

    Hi Drew!
    Does this mean mid-morning Saturday weather could be clear/rain free?
    “A pair of weak cold fronts will move through around dawn Saturday and during the early afternoon….”
    ….or am I just wishful thinking? TCPL has a new Saturday Stories in the Park tomorrow from 11:00 – 11:30, and I’d love to get an idea of whether I’ll need to cancel. We have no cover if it rains.
    Thank you for any further clarification you can provide!

      It isn’t a slam dunk, but I would be feeling fairly good about going ahead with your Story Time. On the off-hand chance it did rain during that time, it would probably be light and brief.
