A cold front with an Arctic air mass behind the passage of the front is moving through the region this morning with scattered snow showers for much of the region. The cold front is currently located in western Pennsylvania and will move east through the day. Winds initially from the southwest will allow afternoon [...]

A weak disturbance is moving through the Philadelphia and New York City metropolitan areas this morning with a few scattered snow flurries. No accumulation is expected, however the snow showers will likely put a nice touch to the cold conditions in place right now. Let’s be honest, what’s the point of it being cold [...]

If you want to see what a developing strong negative NAO pattern looks like, take a look at this morning’s water vapor satellite image. The upper low associated with the coastal storm off the New England coast is clearly dominating the weather pattern for the much of the Northeast and Mid Atlantic. The upper [...]

An intensifying area of low pressure over the New England coastal waters will be moving towards the Gulf of Maine over the next 24 hours. As the low pressure intensifies, the winds across the northern Mid Atlantic will increase. By this afternoon I expect wind to range from 15 to 30 mph with [...]

This is what we call a close call!
It is pretty clear at this point that the Sub Tropical and Polar disturbances will phase too late and too far east to have much of an effect on the northern Mid Atlantic. However, just take a look at how close this phase was to [...]

The big story this morning is obviously the potential significant snowfall for the coastal locations of the northern Mid Atlantic. I will be diving into my thoughts on the evolution of this storm, and what to look for in the next 24 hours in guidance in a minute.
First, the conditions of this morning should [...]

This post is going to lack images. I want to focus on trying to explain this without any distraction as we enter a period of weather that may lend to some rather wintery results. Let me be clear, this pattern may reload at some point in December, but that reload will be brief as [...]

The cold front from yesterday is long gone, however the surface low over the St. Lawrence Valley, which broke a record for low pressure intensity in December for Michigan by the way at 970 MB, is producing a very strong pressure gradient over the eastern Great Lakes, the Northeast, and the northern Mid Atlantic.

Model guidance for this period is starting to come into line with my thinking of a basic non-event for the potential storm on Sunday night. Let say right off the bat, that I think the 00Z GFS over phased the disturbances on Sunday morning, which lead to the big rain storm on the model [...]

I would call yesterday’s storm, the storm that over performed. I was very surprised to see that Philadelphia received up to 8 inches of snow according to the latest snowfall update, which is double the amount that anyone has seen so far this year from other storms. Meanwhile, in Monmouth County around 6 inches [...]
