A strong cold front came through yesterday evening and bought back the fall chill, the front has cleared the coast but did not make it very far east before being forced to stall out by a ridge out in the Atlantic, as some of the remains of Karen are interacting with this stalled out boundary we are seeing a coastal storm forming off the southeast coast, which is already leading to moisture and clouds streaming back into our area after briefly clearing out last night and this morning
This coastal low will drift north over the next several days slowly , we do have Canadian high pressure and a blocking high setting up so at least for areas away from the coast it will take a while longer for the clouds and showers to come in , but for coastal locations we are already seeing this clouds stream in and the chance of showers will begin over the Delmarva later tomorrow then the Southeast coast of NJ Thursday morning and slowly spreading NW throughout the vast majority of the area during the day Friday
As the low comes north and interacts with a blocking high we will see a pressure gradient develop and increasing East-Northeast winds throughout most of the area, again especially along and east of I95 and along the coast, Thursday and Friday the impacts will spread throughout most of the forecast area with periods of rain and gusty NE winds, and as the low sits and lingers this prolonged ENE flow of 15-20 mph with higher gusts could lead to at least minor to moderate coastal flooding, there is also potential for significant rainfall amounts of 1-3 inches, more along the coast than gradually going down as you head N & W
The peak impacts of this coastal storm will likely be Thursday afternoon through Friday night but as it lingers there will be the chance for isolated-scattered showers and a raw east wind continuing Saturday and Sunday , although the NW interior will likely begin clearing over the weekend, most of the area will have a pretty raw and nasty weekend . Temperatures during the period will be in the 60s for highs and lows in the low 40s tonight than mid 40s to low 50s through Sunday.
There are still more details to iron out here but today by determining where the cold front has stalled out and looking at satellite seeing that moisture is already streaming up the east coast I do believe we will see pretty significant impacts from this storm, especially along the coast.
