Late Week Rain Forecast

A frontal boundary has been slowly inching north over the last several days and has finally cleared the entire Finger Lakes region.

Afternoon showers and storms have developed to the south of this boundary over recent days. Yesterday, this included portions of the Southern Tier.

Before any rain develops, today will start off much like the last couple days. Morning sunshine will give way to developing fair-weather clouds during the late morning and early afternoon.

Temperatures are starting in the 70s and will quickly shoot into the 80s. Mid and upper 80s will be widespread by the mid afternoon.

Scattered showers and storms will then start to pop up and should continue until around sunset. Some storms may be slow moving and could produce areas of flooding. Not all locations will see rain today, though.

The activity should quickly dissipate this evening as the daytime heating is lost. A few showers may linger late enough to impact fireworks displays, but patience with the showers will pay off as they continue to dissipate.

Overnight, only a stray shower or two will be possible. It will be another very warm, muggy night with lows Saturday starting around 70 degrees once again.

The front will press back south on Saturday with more widespread thunderstorms expected.

Thunderstorms should begin to develop along and ahead of the front by the early afternoon. Activity will be scattered at first, but a line of storms will drop south during the mid and late afternoon hours. Most areas should see at least some rain.

A few of the storm cells could be robust with gusty winds and hail. Widespread severe weather is not expected, though.

Temperatures will reach the low 80s before the rain arrives. Most of the afternoon will have rain-cooled temperatures in the 70s.

Dry Stretch with Near Normal Temperatures

Behind the front, temperatures will slowly drop Saturday night. The first half of the night will still be rather warm and uncomfortable, but by Sunday morning, temperatures should reach the upper 50s and low 60s.

High temperatures on Sunday will reach the upper 70s, but dewpoints will be low in the 50s. The drop in humidity will be noticeable.

Sunday will have a mix of sun and clouds with no rain expected.

In fact, rain will not be expected back in the Finger Lakes until Thursday as high pressure builds into the area.

Monday, Tuesday, and Wednesday should all follow Sunday’s example with a mix of sun and clouds.

Temperatures on Monday will be similar to Sunday with highs in the upper 70s. Tuesday will be a touch warmer, with highs reaching the low 80s.

Wednesday looks to be the warmest day next week with temperatures pushing back into the mid and upper 80s. However the humidity does not look to be rising with the temperatures.

Dewpoints Tuesday and Wednesday during the afternoon look to only be around 50 degrees which is very dry, and comfortable, for July.

Showers and storms will move back in sometime on Thursday.
