Fog will burn away, severe weather on the way

7:40 AM
The latest visible satellite image clearly shows that fog has developed throughout much of the forecast area with dense fog advisories issued for much of the region.  The dense fog has developed due to a combination of lingering low level moisture from a few showers early this morning and very light winds.  The good [...]

A Discussion On Mesoscale Dynamics And Impacts Along The Coast

The features I wanted to look at is the frontogenesis from the surface to 700 MB, the track of the 850 MB low, and [...]

A Discussion About The Impacts Of Convective Snow Bands

First, when looking at a radar image, the best way to find convective banding is to look for a band of [...]

Thoughts On Afternoon Data And The Storm For Tuesday Through Wednesday Night

6:26 PM
I don’t think anyone can argue that the model guidance has warmed.  There has been little shift in the actual storm track, but the low pressure systems that impact the forecast area appear to have stronger WAA at the mid levels are the very least.  There is a lot to consider here, but I [...]

The Only Consistency In The Models Is Inconsistency

I’ve been getting a lot of emails today about the period from Sunday through Thursday.  Actually, I’ve been getting a lot of emails over the past 4 days about this period.  I want to just send an apology if you didn’t get a response, consider this post your response.
My confidence for the period of [...]

Pressure Falls Everywhere, But Not A Closed Circulation

This morning there are a lot of pressure falls developing.  One interesting pressure fall is over the coastal waters of Massachutes that might indicate a developing low pressure system, but there is not one hint of redevelopment in the wind vectors.  Another pressure fall is right over southern New Jersey, with a bit more [...]
