Things will cool way off over the next week!

 

Over the next 5-7 days, we’re going to be in a fast flow with predominate ridge out west with overall troughing in the east.  Over the course of the next several days several shortwaves will move along the northern Jet.

Today

As a quick moving cold front moves through, clouds will fill in throughout the day Friday and around and along the front there will be a few passing showers. But it won’t be raining most of the time.

The weekend

 

 

On Saturday the front will continue to slide south, as high pressure drops out of Canada. Behind the front it will be cool but pleasant. The air will be drier for that north of the frontal boundary. The front will be south of the Mason Dixon Line those across Maryland, Delaware and Southern New Jersey. Will be dealing with more or less isolated rain showers.

Later Saturday into Sunday tropical moisture will be working northward. This will help augment a small area of low pressure moving along the frontal boundary. As the shortwave in the northern stream interacts a little with the shortwave in the southern stream moving over the Delmarva Peninsula. We’re likely to see the front meander north a bit, but the high pressure and dry air will limit how far it can come. But southern Pennsylvania along with Maryland, Delaware and New Jersey will see clouds build in along with some rain showers. The tropical influence should allow for rain to be locally heavy at times across Maryland, Delaware, into southern and central New Jersey. We will have that disturbance in Canada, that will bring the chance for some rain showers across northern parts of our region.

Generally, the weekend will see seasonal and cool weather for the weekend

Next Week

 

Monday into Wednesday will see high pressure setup and we will see temperatures become even cooler.  Nighttime lows will be very chilly bringing the chance for freezing and frost, especially across New York State into northern Pennsylvania and New England. The higher elevations across northern New York State and northern New England could see overnight temperatures in the upper teens through the 20’s. By Thursday the high pressure will have pushed off the Coast, the flow will turn southernly allowing for temperatures to be come seasonal, with a beautiful end of the week.
