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 [...]

Threats to consider today-flash flooding and tornadoes?

9:00 AM
A tornado watch is in effect over much of central and southern New Jersey this morning and is in effect until 12 PM.  The potential in an isolated tornado lies within the thunderstorms entering from the Atlantic and moving over the coastal plain.  The majority of these thunderstorms are weak and are not expected [...]

Active afternoon expected, Bermuda high to develop next week

9:01 AM
After looking at some great surface, mid level, and upper level data from the SPC, it appears that a deformation zone is attempting to form over eastern Pennsylvania down through eastern Maryland.  
The snow is already falling heavily over parts of central New Jersey, however that snowfall is associated with a separate mesoscale disturbance [...]
