Discussion

The major coastal storm that pushed slowly northward yesterday along the Mid-Atlantic coastline has stalled out over southern New England and colder air in the mid and upper atmosphere is “wrapping around” the surface low pressure system. At the same time, a little piece of upper-level energy (arrow) is rotating around the surface system from the Ohio Valley and this will act to reinvigorate the upper-level low today at 500 mb (see map) which will keep the atmosphere very unstable. As a result, snow showers will threaten from later this morning into Thursday across the region and there can even be a few heavier snow squalls in this still quite unstable atmosphere with some accumulations and slick spots possible. The surface low will finally relinquish to high pressure on Friday and dry weather is likely during the upcoming weekend.
