WEATHER BLOG: Chilly Night

To end the weekend, it will feel more like March than mid-May. An unusually cold upper level low will continue to spin across the Northeast with strong cold air advection and strong WNW winds. While we start out with some sun, clouds are expected to develop during the afternoon hours. It is not out of the question that some of these clouds could produce a spotty shower or sprinkle in some areas, but any area should be fairly isolated. The best chance will be north and west of the city. Temperatures may fail to reach 60 and are expected to stay in the 50's much of the day. The wind will make it feel even cooler.

By Sunday night and Monday, this low will move northward into Canada as a weak ridge and surface high pressure move into the area. This will create clearing Sunday night and a mostly sunny day on Monday with temperatures a bit warmer than Sunday. It will still be breezy during the day. Heading into Monday night, an upper level trough will begin to dig across the Upper Great Lakes. An increase in low- to mid-level moisture will aid in the development of a batch of rain to develop from the southern Plains toward the mid-Atlantic. Its possible some of this rain arrives on the city's doorstep by dawn Tuesday. Rain can break out anytime from Tuesday through Wednesday in the viewing area. How long the rain stays around is likely to depend on a surface high developing across the north-central U.S. and how fast it pushes eastward to the East Coast and moves the storm offshore. Regardless, Wednesday looks to be a cool day with the upper-level low overhead as well as clouds and showers. It does appear that high pressure will be in control of the weather starting on Thursday bringing a delightful end of the week as temperatures trend upward.
