First Arctic Air Blast of the Season On its Way!


The early part of this outlook will actually start out on the seasonal to perhaps slightly above seasonal. However do not get use to it. Today a cold front will be making its way across the region providing windy and rainy conditions along the mid atlantic into the Northeast. This cold front and upper level low will move out of the region and on thursday a ridge will attempt to move into the area. This ridge of high pressure will be in control of the weather thru about Friday. Late friday night/ early saturday this area of high pressure will start to move off to the east and away from the coast as a powerful cold front approaches the region with an area of low pressure along the front. This will likely provide another round of rainfall from Friday into early saturday morning. Meanwhile, another area of low pressure looks to develop over the Southeast later on saturday evening and that starts to head NE up the coast and could provide the southern Mid Atlantic with some rainfall on Sunday. This low pressure though will not be able to ride up the coast though as the cold air that is pressing south and east will shunt this storm system off to the south and the east
Now this is where it starts to get fun smile.gif Another area of low pressure or piece of energy will be diving down thru the midwest. While at the same time the leading edge of the cold air is working its way towards the region. Depending on how much this energy digs will determine how soon the cold air is able to work into the region and then also will determine how far south this energy will be able to dig. The stronger the push of cold air ..the more this piece of energy will be able to dig. This energy then looks to transfer its energy to a low that develops somewhere off or along the east coast. Again this is all going to be dependent on just how much digging this piece of energy can do and how strong the push of cold air is. The air that is coming in with this system will be the coldest air of the fall season so far. Matter of fact this air will be more similar to an Arctic Air mass that you would get in winter time.
So to sum things up..Early in this period we will be looking at seasonal to perhaps slightly above normal temps but towards the middle and ending and beyond as well...temperatures will be below normal and could end up much below normal! How long will this cold air last is the question? We will cover that in the next update!
