Another round of rainfall is expected tonight with this storm, however the worst conditions are over.
The storm developed initially as a frontal boundary off the New Jersey coast. As a strong upper low started to drive towards the Mississippi Valley, the low and eventually mid level winds began to veer to the southeast off [...]

The temperatures may be warmer, but the active storm track that the Philadelphia and New York City metropolitan area experienced in February is returning once again.
The easterly fetch developing at the mid and lower levels of the atmosphere is already influencing the northern Mid Atlantic as Atlantic moisture moves into the coastal plain. The [...]

One of which, that even suggest that the coastal low becomes the primary low SOUTH of the northern Mid [...]

Obviously tonight all of our focus is on the storm that is on the way for Saturday. This afternoon, the model guidance took a strong swing towards what I defined two days ago as scenario 3, which is a full phase intense winter storm that is capable of producing significant snowfall.

While high pressure and a building ridge holds sway over the Mid Atlantic this evening, trouble is brewing over the Southwestern United States.
Tropical Storm Rick, at one point a strong hurricane, is racing to the northeast towards mainland Mexico. The moisture from this tropical system is already interacting with a strong disturbance over the [...]
