Arctic cold in place, snow creeping north

9:23 AM
There’s a lot to cover this morning!  So let’s get to it!
The area of precipitation that will impact the northern Atlantic this afternoon through this evening is currently developing over the Tennessee Valley and western Virginia under the influence of the strong Sub Tropical disturbance that is driving towards the Mid Atlantic coast.  The [...]

Very cold day on tap for northern Mid Atlantic

7:50 AM
In case you haven’t realized from the gusty winds from last night, Arctic air has arrived for the New York City and Philadelphia metropolitan areas.  Temperatures this morning are in the single digits and teens over many interior locations and mid to upper 10’s along the coast with a gusty northwesterly wind around 10 [...]

Verification Analysis Of The Pre Christmas Blizzard of December 2009

6:00 PM
Now that the winter storm is over, it is time to see how I did with this storm.  The forecast analysis appeared to be a picture of two worlds.  Over the interior, I feel I did poorly which I will discuss what went wrong.  Meanwhile, the forecast along the coast could not have been [...]

Evening Thoughts- starting to piece the storm together

8:53 PM
Tonight I want to step away from the models, which are certainly trending towards the third solution I discussed this morning and instead put together how I feel this storm will come above. To do this, I am going to use the water vapor satellite picture and hope that you’ll follow me along on [...]

Rain, snow, and ice on the way

8:30 AM
Rain, sleet, and even some snow is racing northward and eastward  from  the southern Mid Atlantic and Ohio Valley.  A coastal low is slowly forming off the North Carolina coast while pressure is quickly falling throughout the Tennessee Valley and Mid Atlantic.
My concern this morning is the cold air that is locked in [...]

Evening Thoughts: The approaching snow event

8:20 PM
Tonight I am going to focus on the next 36 hours as a moisture loaded low pressure system approaches the northern Mid Atlantic, which will be under the influence of a cold Polar air mass.  The forecast of this storm is no doubt difficult to nail down as there are two significant competing features [...]

The atmosphere is still capable of supporting heavy downpours over much of eastern Pennsylvania, New Jersey, and [...]

Nor’ Easter stalls over New Jersey

2:30 PM
The upper low associated with the coastal storm today appears to be slightly stronger than expected.  As a result, the coastal low has now moved into south-central New Jersey and is expected to stall over central New Jersey over the next 24 hours.
The 850 MB low has matured to a point where the low [...]

Fall-like conditions visit Mid Atlantic to start September

5:25 AM
At least for one day, early fall like conditions will return to the forecast area as high pressure continues to build into the region.  High pressure will remain in control over the forecast area through the next three days, keeping much of the forecast area dry with generally clear skies.
The air mass in place [...]
