Dry After Morning Showers

A weak area of low pressure is passing through the Finger Lakes this morning with a few scattered showers.

The rain will continue to track south and east and should exit the region by the mid to late morning. Not everyone will see rain this morning and only a few isolated areas will see a brief, heavier burst.

After the rain departs, clouds will begin to break up and allow for increasing sunshine this afternoon.

Temperatures will peak in the early to mid afternoon with highs in the upper 60s.

This morning’s low pressure system is located along a west to east frontal boundary draped from the Midwest into New England. This boundary will sag to our south tonight, allowing some cooler air to seep in.

With mostly clear skies also in place, temperatures Saturday morning will end up near or just below 40 degrees. A few isolated, typically colder locations could end up in the mid 30s. Frost is generally not expected, but if you live in a location that typically gets colder than surrounding areas, it may not hurt to take a few basic precautions for your plants.

A light north wind Saturday will turn to the east during the afternoon. Skies will be a mix of sun and clouds with no precipitation expected.

Temperatures will be around 60 degrees across the north with mid 60s across the Southern Tier.

Summery Sunday-Monday

Saturday night, the front to our south will jump north. An overnight shower cannot be ruled out, but these will be widely scattered, and most areas should stay dry.

Temperatures Saturday night will initially fall into the low and mid 50s but will rise after midnight. Most areas should be in the low 60s by dawn Sunday.

Sunshine and a gusty south wind will cause temperatures to warm rapidly Sunday morning. By the afternoon, temperatures will be in the low and mid 80s with muggy dewpoints above 65 degrees.

A few showers and thunderstorms will pop up in the hot, humid air. Most likely, these will develop along the lake breezes south of Lake Ontario and east of Lake Erie. There are some subtle signs of a small boundary that could trigger some more widespread activity though. This will need to be monitored.

A chance for showers and storms will continue through the night and into early Monday with temperatures holding in the 60s. The best chance for rain on Monday will be during the morning., but again, not all areas will see rain.

A front will move through during the day, first bringing less humid air, then cooler temperatures. Still, highs Monday should reach well into the 70s before any cooler air arrives.

Tuesday will be sunny and cooler with highs in the upper 50s. The next chance for rain will come late Wednesday. At this point, that rain looks like just some scattered showers.
