A humid airmass is in place across the Finger Lakes and will interact with weak disturbances in the atmosphere to produce some thundery downpours today.
Already this morning, some thunderstorms have rumbled through parts of the region with locally heavy rain as one of these disturbances passes through. These showers and storms will continue to depart the region, and most of the morning should be quiet.
Clouds will remain thick, though, with little to no sunshine expected. Without the sun, temperatures will be slow to rise and probably will not quite reach 80 degrees for most areas.
Nonetheless, dewpoints will remain near or above 70 degrees, making the air feel muggy and heavy.
Another bundle of atmospheric energy will move toward the region this afternoon, leading to an uptick in precipitation. Scattered to numerous showers and storms are expected through the afternoon hours as they move along from northwest to southeast.
Severe weather is not expected today, but localized minor flooding could be an issue, especially if areas see multiple rounds of heavy rain. Overall, though, the flooding risk is minor.
A few showers may be possible tonight, but most of the activity will wind down as the sun sets.
Tomorrow will also be very humid with dewpoints remaining around 70 degrees. Sunshine will return, helping temperatures into the mid 80s. A few isolated afternoon showers or storms may pop-up, especially across the southern half of the region. Most areas will stay dry, though.
Thursday will see drier air work in from the northeast as high pressure moves across Canada. Dewpoints should drop to the 50s and low 60s. Few clouds are expected, and the sunshine will push temperatures further into the mid 80s.
While Thursday will remain sunny and dry, an unsettled weather pattern will persist for the rest of the week and the weekend.
Moisture will push back north on Friday, resulting in dewpoints rising back into the mid and upper 60s. Scattered showers and thunderstorms will also develop as a result.
Friday does not look like a washout, and the morning in particular looks quiet. Highs should be able to push into the low 80s.
Saturday looks to have plenty of dry time as well. Overall, the chances for rain will be fairly low and mostly during the afternoon. Just a few scattered showers are expected.
High temperatures on Saturday will be a touch cooler, mostly settling in the upper 70s. Dewpoints will generally be below 65 degrees.
Sunday will bear some watching as a cold front moves into the area. It is too early to be confident on the timing of the front or the ingredients for severe weather, but there is at least a chance for the puzzle pieces to match up for some strong storms.
Showers will remain possible Monday and Tuesday with highs sticking to the 70s.
A well organized low pressure system is being hinted at on the models for the middle of next week which could bring steadier rain to the area. Temperatures would remain cooler with highs in the 70s, or possibly even 60s for a day or two.
