A warm front continues to move through the Delaware valley Tuesday evening, allowing for a mild air mass to briefly return.
Tuesday’s high temperature reached 54 degrees, while the average high is 41. A push of mild and moist air will flow in from the south, allowing for an area of fog to develop Tuesday night that will linger into Wednesday morning.
A strong cold front will approach the region on Wednesday with an April-like air mass just ahead of it. After some morning fog, expect mostly cloudy skies with breezy conditions to develop with highs in the low 60s. If some sunshine breaks out, temperatures will be even warmer and may reach 70 in southern Delaware.
As the front approaches late in the afternoon, the winds will increase from the south and become gusty. Rain will begin to develop late in the afternoon and evening and possibly become heavy at times overnight. A thunderstorm is even possible at night with the mild air mass in place. One to two inches of rain is possible with a flash flood watch for Wednesday p.m. through Thursday morning. A high wind watch is also in effect for coastal NJ for Wednesday afternoon through late Wednesday night.
Cooler and drier conditions return behind the front on Thursday with highs back into the mid 40s. Even colder air arrives for Friday through the weekend, with highs in the 30s with some flurries possible Friday and Saturday night.
