Day-by-day forecast

Synopsis:

A mature low-pressure system will cross directly over the state of New York on Saturday, bringing with it persistent moderate, sometimes bordering on heavy, rain. Along with that will come temperatures much cooler than is typical for the beginning of summer. Temperatures will hover in the low 60s for Saturday, and as the back end of the low-pressure system moves through on Sunday, wrap-around colder air from the Arctic will make it difficult to even get out of the 50s for Sunday. The coldest high temperature for June 28 on record is 62 degrees, set back in 1974; we will probably surpass that figure tomorrow. Sunday will not be quite as wet; a few lingering scattered showers will still be in the area, but it will not be everywhere. Most of Monday should be dry and back to temperatures closer to our seasonal norms.

Models are showing the development of another small low with a reinforcing cold front that will graze the southern shores of the Great Lakes, most likely on Monday night, bringing yet another round of rain showers. There is still some uncertainty as to exactly when this one will arrive, and its storm system is not particularly well-defined. What will probably happen is that we’ll get a few light showers from Tuesday through Thursday, each day fewer and lighter than the one before. By Friday, July 3, conditions should be back to dry, probably even sunny, and fairly warm (but not by any means hot), ideal for Independence Day celebrations.

Heading into the very long range, there is yet another rain system in the forecast, with the model consensus seeming to suggest Sunday, July 5 as the likely day for its arrival (one model is trying to rain on the parade, perhaps literally, by bringing the rain through on July 4, but it appears to be an outlier). Once that system clears out, the bulk of the first full week of July appears to be dry and seasonable—dare I say, summerlike.
