Discussion
Strong low pressure will push towards the eastern Great Lakes over the next 24 hours and this system will generate a significant rainfall for the DC-to-Philly-to-NYC corridor on the order of 1.00 to 2.00 inches. As the storm pulls northward, it’ll force somewhat milder air into the I-95 corridor and this could help generate some strong thunderstorm activity to go along with the periods of rain – some of which will be heavy at times. Following the passage of a strong cold front, colder-than-normal air will push into the region this weekend and, thanks to the formation of a classic “omega”-shaped blocking pattern in the upper atmosphere, it will stay colder-than-normal around here - and somewhat unsettled - for several days.
