Too much, too fast
The Finger Lakes is in need of soaking rainfalls, but today will hold the potential for seeing too much rain too fast, possibly resulting in some areas of flash flooding.
In the wake of Tropical Storm Fay last night, a disturbance will slowly spin its way across our region today. This feature shows up strikingly on radar this morning over Lake Erie. Heavy rain and flooding have been associated with this system since yesterday.
Some breaks of sun this morning will help heat temperatures into the 80s. Humid air is also in place, with dewpoints ranging from the mid 60s to low 70s.
Thunderstorms will fire this afternoon, first along the I-90 Corridor west of Geneva. Additional storms will then develop east of Seneca Lake while more widespread rain and downpours move into the western Finger Lakes.
This widespread rain will push through the rest of the region during the late afternoon and evening.
There is potential for slow-moving, persistent downpours with the thunderstorms and the widespread rain. Localized areas could see an inch or two of rain quickly, producing flooding. There is potential for a few places to see as much as 3-5 inches of rain today.
In addition to the flooding potential, one or two storms could turn severe with damaging winds. Widespread severe weather is not expected though, and flooding is of greater concern today.
The rain will exit the region tonight, but areas of dense fog will be possible in its wake. Only a few scattered showers are expected on Sunday. These will not be enough to produce any additional flooding, but nor will they be overly beneficial in terms of our rainfall deficits.
