Rain Returns as Humidity Pushes Back
A small disturbance will touch off showers this afternoon as warm, humid weather starts to move back towards the Finger Lakes.
Conditions should remain dry this morning, though showers are already scattered about Pennsylvania along a boundary between very moist air over the Mid-Atlantic and dry air over Canada.
Winds will swing around to the southeast today as the disturbance approaches from the west. Some of that moisture will start to work its way towards the Finger Lakes as a result.
By this afternoon, showers and a couple of thunderstorms should be spreading north into the Finger Lakes. While there will be numerous showers, the rain will stay in small individual cells. It will be the sort of set up where it is raining in one town but the neighboring two or three towns will be dry.
Winds at the surface and aloft will be light, so rain showers will be slow moving. Any heavy downpours that develop could produce some minor poor drainage flooding as they slowly drift along.
Showers will diminish, but not completely end tonight. A few spits of rain will continue into Saturday morning before the area dries out for Saturday afternoon.
Temperatures on Friday will reach the upper 70s. Saturday will see temperatures warm the most in the northwest, with mid or upper 80s in Rochester while Ithaca settles in near 80 degrees.
Dewpoints will reach the mid 60s today and 70 degrees on Saturday. Dewpoints at or above 70 degrees will then persist for most of next week, along with widespread 80s and perhaps a 90 degree day or two.
Showers and storms will be possible Sunday, Monday, and Tuesday, but the best chance for rain seems to be on Monday. Additional chances for rain will come in later next week as well.
