An area of low pressure traveling east through the Great Lakes will bring a few chances for thunderstorms today.
While the heat will not totally break yet, the presence of extra clouds and occasional storms will mean it will not be quite as hot today.
An initial batch of thunderstorms is working into the western Finger Lakes as of 7 AM this morning. There should be some weakening of this area as it moves east-northeast, but it will likely hold together at least somewhat through the morning hours. The northern and western halves of the region are most likely to see rain from this cluster.
Additional showers and storms may not develop until the late afternoon and into the early evening hours. These scattered storms may have some localized strong to severe wind gusts in addition to frequent lightning and heavy downpours.
Outside of the storms, skies will be mixed, humidity will be high, and temperatures will be warm. Most areas should see highs in the middle 80s, though a few pockets of upper 80s will also be possible. Heat index values should be near or under 90 degrees thanks to dewpoints in the upper 60s.
Evening temperatures will be slow to drop through the 70s but should make it into the 60s by midnight. Any lingering showers or storms should dissipate by then as well, leaving a quiet yet mild overnight with lows in the mid 60s.
A front associated with the low pressure system will stall out to our south on Friday, meaning much of the area will be dry much of the time. Scattered showers and maybe a thunderstorm will be possible, especially in the afternoon across the southeastern half of the region.
Temperatures will continue their retreat with highs in the upper 70s and low 80s. The humidity will not change much, however, with dewpoints sticking to the mid and upper 60s.
Rain Chances, Temperature Slide Continue
Like Friday, much of Saturday may end up dry for much of the region. However, there will be an occasional cluster of showers to dodge.
The chances for rain look highest in the early morning and possibly predawn hours as a small wave of atmospheric energy passes by, and again during the afternoon. Like Friday, southern and eastern areas will stand the best chance for some occasional rain.
Temperatures on Saturday will top out in the mid 70s.
Rain chances will increase Saturday evening as the front creeps back to the north over our region. Sunday looks rather wet with showers and a few thunderstorms likely throughout the day. Widespread rain amounts over a half inch are possible.
With plenty of clouds and rain on Sunday, look for highs to only make it to the low 70s. There will still be a noticeable lack of relief from the humidity, though, with dewpoints remaining in the mid and upper 60s through the weekend.
Winds will also be nearly calm through the weekend thanks to the stalled-out frontal boundary.
The front will head back south on Monday, finally bringing in less humid air as dewpoints fall to the 50s during the afternoon. After a few morning showers, the afternoon looks mostly dry. High temperatures will be in the low and mid 70s.
The next weather-maker looks likely late Tuesday through Wednesday with showers and a few thunderstorms. Temperatures will stay in the low 70s on Tuesday and will only be around 70 on Wednesday, Thursday, and Friday.
