As high pressure brings dry conditions and clear skies to the northern Mid Atlantic, a moisture loaded storm is brewing over the Southeast. This time the Philadelphia and New York City metropolitan areas will not have to worry about the developments along the Gulf Coast as the strong low pressure that impacted the region [...]

I want to wish everyone today a HAPPY THANKSGIVING!
This is the time of year we should give thanks for the things we have in our lives, and I’m not talking about that new video game with the kung fu grip. This is the time to be thankful for friends and family. For jokes and laughter, [...]

A strong disturbance over the Ohio Valley is gaining strength and diving southeast towards the Mid Atlantic coast this morning. This disturbance will spawn a coastal low late tonight off the Delaware coast that will have some minor direct and significant indirect impacts on the Philadelphia and New York City metropolitan areas.
Through today, clouds [...]

Is that trouble brewing off the coast? Well, the weak low pressure system off the Virginia coast could have been a much bigger issue, however the timing of the Polar and Sub Tropical disturbance did not match up to produce a proper interaction. Still, it is interesting to see the strength and tenacity of [...]

While model guidance has been jumping all over the place over the past several days, the forecast idea I’ve had for this time period appears to be coming to fruition. It’s not that I [...]

The 12Z GFS is coming in as I type and the stormy potential is becoming more impressive for the Mid Atlantic.
The latest guidance continues the theme of a disturbance over the eastern Rockies from the Sub Tropical Jet Stream interacting with a disturbance from the Polar Jet stream. By Thursday morning, this disturbance intensifies [...]

A weakening cold front is approaching this evening with scattered showers over much of Pennsylvania and central New York. The cold front will continue to slowly move through the region over the next 24 hours.

This afternoon, the trough that brought overcast conditions to much of the northern Mid Atlantic through this morning is exiting the Northeastern coast. Note the axis of this trough, which is tilted from southwest to northeast. This tilt is caused a “positive” tilt and at this position with the axis along the region, subsidence [...]

Hurricane Fred continues to slowly weaken over the eastern Atlantic as strong southwesterly upper level winds are producing significant shear over the tropical system.
The majority of the convection with Fred is focused over the northeastern quadrant of the storm this morning. Fred continues to drift northward as the steering currents have become weak due [...]

The tropical Atlantic continues to remain very quiet for this time of year. The most pressing area of disturbed weather is over the Bahamas and is associated with a coastal low developing along the Carolina coast. Otherwise, conditions continue to remain quiet.
A deep trough has driven through the Gulf of Mexico and is producing [...]
