Cold Canadian air has made its way back into the Northeast yet again this spring following a cold front that pushed through the region late on Friday.
The intrusion of cold air will be amplified by an area of high pressure over the upper Mississippi Valley. The flow around this high will promote a northwesterly wind, resulting in chilly conditions for New England.
Temperatures across much of the Northeast will struggle to climb out of the 40s on Saturday, with warmer temperatures being limited to coastal areas.
This colder air will allow for some late-season snowflakes to mix in with rain showers across New York today as moisture wraps around an area of low pressure over northern Quebec. Some areas could even have some frost on Saturday night with temperatures dipping below freezing.
Temperatures will slowly rise on Sunday as high pressure builds in from the West; yet it will still remain well below normal.
Below-normal temperatures have not been uncommon so far this spring. The first week of spring in New York City averaged 6 degrees below normal, with other places across the Northeast kicking off spring below normal as well.
Warmer, more seasonable temperatures will return by the start of next week as a new storm system forms in the Plains; drawing in milder air from the South.
