Updated: Heavy rain likely today, cold and calm weekend

Soaking Rains Likely on Thursday

High-resolution model guidance has been consistent in the suggestion that an area of heavy rain associated with an area of low pressure moving along a cold front will be located near the area for the rest of the morning. A strong upper level jet streak will be positioned just off to our north and west. This will provide ample lift for pockets of moderate to occasionally heavy rainfall during the early afternoon hours. In fact, there may even be a line of heavy showers and thunderstorms within this main area of rain that could produce some gusty winds of up to 30-45 mph and flash flooding–especially for locations with poor drainage. Accordingly, the National Weather Service has issued a Flash Flood Watch for the entire NYC metro area through 6 pm.

Clear and cool start to the week, attention turns to Friday

Temperatures were be quite cold to start the day  across the vast majority of the Northeast – and they still are! Dry air has moved in to the region from Canada as well. This will keep any clouds at bay, allowing for a mostly sunny day, with temperatures in the lower to middle 30’s for much of the area, with the usual colder readings off to the north and west. A weak area of high pressure will gradually build-in during the course of the afternoon/evening hours which will continue the cool and clear conditions into the overnight hours. With dry air in place, a building high pressure system, and light winds, radiational cooling will be near-ideal tonight. As a result, low temperatures will once again be quite cold area-wide. Reading should easily drop down into the lower to middle 20’s over the immediate metro area, with teens possible just off to the north and west.
