Rain Arrives Thursday Into Friday As Cold Front Moves Through Weekend Outlook
We continue to move along in a rather quiet weather pattern for the next two days. Weak disturbances moving east are producing occasional clouds. Most of the time today skies will be no worse than partly sunny. There is no real cold air around not just in the Northeast US but most of the country is seeing if any colder Canadian air let alone arctic air which is pinned up way north in Canada and around the Arctic. In the meantime high temperatuers this afternoon will be in the low to middle 40s. Tonight will be another night of clear to partially clear skies. Most lows tonight will be in the mid to upper 20s inland and low to mid 30s warmer urban areas.
Wednesday looks to be a nice day of partly sunny skies or no worse than partly sunny skies. Wednesday high temperatures will be in the mid to upper 40s after a chilly start. This is rougly 8 to 10 degrees above average. We will likely see clouds increasing Wednesday night into Thursday morning as the next cold front to the west makes its approach.
Thursday we see clouds thicken quickly. Low pressure from the Central Plains heads quickly to the Great Lakes. There is no cold air anywhere so this is rain from start to finish not just in Eastern Pennsylvania to Soutehrn New England but you probably need to go all the way up into Northern New England to see any snow and even there it will be pushing it.
Showers will likely hold off until the afternoon and evening as the cold front nears. Temperatures on Thursday will likely reach up into the 50s everywhere. The front will move through later Thursday night and most of the rain will be ending from west to east around or shortly after midnight. This should leave the area dry by Friday morning. rainfall amounts will likely be in the half inch range in most places.
Friday we will see leftover clouds with some sunshine and high temperatures Friday will be in the 50s but that will likely be leftover from the overnight before the front passes. We will likely see temperatures settle in the upper 40s and lower 50s during the day Friday and then drop down into the 30s by Saturday morning. The air behind this front is once again only marginally cold at best and we will see temperatures only take a stair step decline. We are going to for now lean away from the idea that some sort of secondary wave develops and creates an issue Saturday into Sunday morning at least for now. 9 times out of 10 when models show this, it winds up either being further south or further east and not a problem for the Northeast. So for now we will go for a dry and colder weekend though temperatures will still be above average.
