Discussion
A back door cool front passed through the region last night and it’ll turn a bit cooler today with a low-level flow of air out of the northeast. This same front will turn around later tomorrow and advance to the north as a warm front. As a result, it’ll turn warmer on Thursday and become quite warm on Friday along with increasing south-to-southwest winds as we close out the work week. A strong cold front supported by vigorous energy in the upper atmosphere will grudgingly works its way to the east coast at the end of the week and this will result in a soaking rain event for the DC-to-Philly-to-NYC corridor from later Friday into early Saturday. In addition to the heavy rainfall, there is quite likely to be a threat for strong-to-severe thunderstorm activity in much of the Mid-Atlantic region later Friday and Friday night. As the upper-level low crawls to the Mid-Atlantic coastline this weekend, it'll remain mainly cloudy on Saturday and instability showers will remain a threat. Skies should become partly sunny on Easter Sunday, but a shower cannot be ruled out.
