Here is one of those days where I just bowed to mother nature and said, “You won this round”. The setup here is a strong ridge of High pressure dominating the eastern seaboard which pretty much rules out much of a synoptic breeze (frontal generated). I thought this would be a…

The Saharan Air Layer, or SAL, is fed by Easterly mid-level jetting over the deserts of Africa…
The cold water temps of this Spring are producing quite a strong engine for thermal assisted sea breezes. One area the typically is a firecracker for the sea breezes is the inner passages for Rhode Island. Today I suspected this might happen but I shied away from it due to the large amount…

Just caught a good example in the VA area of conditions that reflect two of my staple bullet points in synoptic setups such as the one we are seeing today. (*Heads up for fluky conditions / shifty directions as each synoptic feature changes position / gains and or loses influence) and (*Showers and or thunderstorms…
So you may be thinking to yourself… There’s a cold front approaching our area from the W, so I just might get a session in today. Well, in an ideal approaching cold front setup with a strong well positioned center of low pressure associated with the boundary and a strong high pressure out in the…
South and SW gradient winds have a seriously hard time reaching the surface along the Connecticut coastline due to the topography of Long Island and the quite cool waters of Long Island Sound. Usually the southerly flow is a warm flow and thus the winds decouple over the waters and land inland. Not…
This snapshot of wind observations combined with a radar image of storms moving through NJ from W to E is a good example of a gust front / outflow boundary increasing our wind speeds out ahead of approaching storms. A gust front / outflow boundary is simply a storm scale mass of cold / cool…
The recent synoptic setup lately provides us with a good example of a blocking high entrenched out in the Atlantic. A blocking high is simply an area of high pressure that is relatively stationary for an extended period of time. The series of surface maps below show the blocking high staying put through Saturday morning as it…
This is where our Meteorologists will post topics for their discussion and to share concepts that we observe and help better understand the complexities of predicting winds in the areas that we focus on. Not all posts will have answers, but all are aimed at stimulating discussion. If you wish to comment on…
