Stormy Period for this Week...Wind and Rain Wednesday Night

Low pressure will track northward up the Mississippi River Valley on Wednesday and it will spread a large area of rain to the Mid-Atlantic states and the Northeast. Winds will gust from the south at up to 40 mph Wednesday night and Thursday. On Thursday, the rain will taper off to showers and it will partially clear in the afternoon and the temperature will soar into the 60s. Another storm will form off the coast of the Southeast and will graze the NYC metro area with light rain and/or snow or flurries on Saturday. The NAM computer model indicates that the storm will track to the west of the NYC area (first map above). The tight isobaric spacing indicates that there will be a strong southerly wind ahead of the storm. The blue dotted lines are thickness lines that correspond to colder air across the Midwest and Canada and this colder air will move in here after the storm moves into eastern Canada. The computer forecast below is from the GFS model which is forecasting most of the precipitation and development from the second storm to be out into the ocean thereby only grazing the Northeast. This storm is still several days off and the upper-air pattern and future models can change so this storm bears watching in the next couple of days. At this time, no major snowstorm is forecast for the next week to 10 days here in the Tri-State New York region.
