You can see the Low spin out of what looks like just a small area of clouding; however, this was not the case. Surface circulations were already at work ahead of the…
by WeatherFlow meteorologist Shea Gibson. As a quick recap, The Intertropical Convergence Zone where tropical storms form, or the “ITCZ”, is heavily impacted by the Saharan Air Layer (or “SAL”), which is a dust layer off the western African coast along the lower and mid levels of the atmosphere. This dry, dusty more stable air rides just over the…

(*Heads up for fluky conditions / shifty directions as each synoptic feature changes position / gains and or loses influence) and (*Showers and or thunderstorms…
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…
