A coastal low pressure is developing to the east of the area, producing widespread moderate-heavy rain across eastern New England while the showers that affected Long Island and CT yesterday have moved out. This storm will clear the region tonight, bringing seasonable temps for Saturday, while a weak cold front produces scattered showers and thunderstorms for Sunday. Seasonable conditions will return for the early week again ahead of mid-late week thunderstorms.
Thursday, July 25 Observations:
With the frontal boundary stalled to the east, showers developed along the front and extended northwest to reach Long Island and CT, with isolated showers reaching the immediate NYC area. Showers were generally light to moderate with up to 1/4 to locally 1/2 inch of rain in most of Long Island and CT, although a band of heavy rain set up in eastern CT with totals locally as high as 2-3 inches. With the cloud cover and showers, high temperatures were unseasonably cool, nearly 15-20 degrees colder than average in some locations; highs reached the mid to upper 60s in the immediate NYC area, and the upper 60s to low 70s in eastern Long Island/CT and interior western locations. The warmest temperature was 72 degrees in Montgomery, NY.
