A storm system centered over the northern Plains this afternoon will impact central New York from tonight right into the upcoming weekend.
Even though low pressure is still well to our west this evening a cold front that stretches from the center of the low extends as far east as western New York and Pennsylvania. Southerly winds ahead of this front are transporting an increasingly moist air mass for late October into the region. We expect rain to break out close to midnight and continue overnight. The rain could come down hard at times with some parts of central New York receiving more than an inch of new rain by the morning commute.
The cold front will only slowly moves through central New York tomorrow. As this happens, it appears the steadiest rain will start to shift to our east. By afternoon we will be left with scattered showers.
Over the weekend, the parent low pressure system will slowly track east across the Great Lakes and then into the Northeast. This low is associated with a pocket of cooler air aloft so our temperatures down at the ground will drop closer normal. In addition, we expect showers both days, although we’re not expecting “all day” rain either day.
The low finally kicks out by Monday and the air coming our way is not only dry but mild yet again. Our temperatures for not only early next but for much of next week look as if they will average above normal.
