The powerful storm moving off the East coast has produced heavy rain and bands of heavy snow. As it leaves, a full-fledged blizzard will rage across parts of the northern Plains this afternoon and tonight. More snow and cold will accompany another storm heading across the Plains toward the Great Lakes later in the week.
A sure sign of spring is severe weather, and we've had some in the past 24 hours. More is expected across the South over the next 36 hours.
Bitter arctic air will be retreating from the East in the next 24 hours, allowing much milder air to move in. However, a series of storms will pull some cold air back into the pattern over the next week or so, though it won't be as intense as it has been.
A massive storm is dumping heavy, wind-driven snow on Cape Cod and parts of Maine this morning, and most areas east of the Mississippi are much below normal. While the cold will quickly moderate over the next 48 hours, it appears as if winter is not yet over for everyone.
Behind the storm in the East over the next 36 hours, extremely cold air will make one last stand before quickly moderating the rest of the week. A couple of waves of low pressure will bring rain from the Mississippi Valley to the East late this week into the start of the weekend, followed by a back-and-forth pattern going into early April that will still be rather cold from the northern Plains to New England.
Extreme cold will prevail through midweek, while a tremendous storm rapidly deepens off the mid-Atlantic and New England coasts tomorrow night and Wednesday. Behind the storm, look for the cold to retreat late in the week.
After a brief warmup this afternoon into tomorrow, much colder air overwhelms the pattern this weekend. That will set the stage for a strong storm to develop Monday night off the Southeast coast, one that could become a classic nor'easter in time.
It will warm nicely over the next couple of days from the central Plains to the East Coast, but much colder air and threats of snow are still a real part of the forecast deep into next week.
While the waters of the equatorial Pacific have been relatively cool in recent months, there are signs of warming. A full-fledged El Nino may soon be developing in the Pacific, and its appearance will have an impact on the weather patterns around the globe in the coming months.
Despite spring being just three days away, the cold pattern shows no signs of giving up through the end of March.
