A stretch of great weather conditions continues today with strong high pressure over the Ohio Valley. The high pressure system, producing a moderating west and northwesterly wind, will slowly move to the East coast over the next several days. The shift in the high pressure system to the Tennessee Valley and eventually the southern [...]

The pattern is certainly changing away from the cold and stormy pattern seen in February to a warmer but just as wet pattern for much of March. Influences from the Pacific and Atlantic will be felt over the Northern Mid Atlantic, but one can be sure that warmer times are ahead.
This morning, a strong [...]

Over the past three weeks, the 500 MB pattern has been generally unfavorable for any significant winter storms for a variety of reasons. At first, the overwhelming strength of the negative NAO suppressed any potential for Sub Tropical disturbances to interact with the cold air at place, leading to a cold and dry [...]

This morning we have an excellent example of why winter storms are so hard to come by in the northern Mid Atlantic and why all features must be in place just right. In this case, the Sub Tropical disturbance certainly delivered with an energetic and impressive storm developing off the North Carolina coast. A [...]

This morning I’m looking at an overwhelming amount of data pointing to a returning cold pattern that frankly, I’ve had a hard time piecing together exactly what I’m seeing and what it means for the northern Mid Atlantic and the East coast as a whole. The implications of the developments at the stratospheric [...]

If anyone has doubts that medium and long range forecasting is a difficult task, take a look at what the MJO has done the past few days. Yes, that lovely feature that helps drive the Sub Tropical Jet stream has produce a nice loop on itself, falling into a state of near non-influence [...]

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 [...]

As of last night, the majority of model guidance started to take a decided jump towards a solution where much of the East coast with the exception of northern New England will miss out on what could have been an impressive snowfall. So what are the models seeing and does the solution thus far [...]

This morning I discussed the potential outcomes of the storm for the period of Saturday through Sunday. One of the solutions that I discussed was that the upper low over Quebec would be weaker and thus the disturbance dropping over central Ontario would have more of an influence while the negative NAO, still clearly [...]

There is a lot of data I was looking at this morning that frankly it can be a bit overwhelming when organizing my thoughts on how to discuss what I’m seeing. In the medium range, the storm that was expected to cut towards the Great Lakes is now trending on guidances towards the East [...]
