8:40 PM: Contrary to the forecast from last night, heavy rain fell through the afternoon and evening hours today, and will continue through at least 10 PM to 12 AM across the area, when the back end of the steady rain, currently over SE PA , will reach the area. An area of moderate to heavy rain ended up training over most of the area, which resulted in rain totals higher than expected. Most of the models from last night showed the rain weakening as it reached the area today, but this has failed to happen, as the radar image to the left and from the 5 PM post show. Rainfal amounts so far have reached the 2 to 4 inch range in northern NJ and SE NY, 1 to 2.5 inch range in NYC, and 0.6 to 1 inch in Long Island/S CT.
After 12 AM tonight, the rain will begin to move back towards the north as the cold front, currently SE of the area, will stall and begin to lift back north as a warm front. This will bring occasional showers to the area tomorrow and on Thursday, but the majority of the rain will stay in Pennsylvania and New York. An additional 1/2 to 3/4 inch is expected to fall through Wednesday morning from NYC and further west and in southern CT, with an additional 1/4 to 1/2 inch falling in Long Island.
Stay tuned for tonight’s update, which will be posted by 10 PM.
Another storm update may be posted later today, otherwise the next full update will be posted at 10 PM tonight, with more information on the outlook for this week, the weekend, and a brief overview of tropical depression 14, which formed this afternoon in the eastern Atlantic.
