GOM system is getting the look

[Stratosphere747]

The pressure falls are normal diurnal falls that occur every late afternoon.

The convection is decreasing and not deep at all. Also, there is no indication of any surface circulation. I would not look for any development from this system unless the thunderstorm activity becomes much deeper and persists for at least another 24 hours.

Thanks for clarifying that..

Keep seeing too many folks announcing these pressure drops when they are normal everyday occurrences.

Yes, I know well they are normal. This is a pretty big drop though. I will be looking for any night time blow up of storms.

do you have a link to the bouy in question?

Nothing much now. worth keeping an eye on especially with the wave from the caribb nearing. See what happens.

What you are seeing with this bouy report is that a cluster of showers and thunderstorms moved across the bouy around mid morning. In the wake of the showers and thunderstorms, a mesohigh build in during the late morning. Notice the big rise in pressure before noon. During the early afternoon, the mesohigh has collapsed resulting in a rather rapid drop in pressure. In reality though, the rapid drop is just leveling out the pressure field to where it should be.

Nothing too unusual here and nothing to be alarmed at.

Thanks for the explanation.

What's a mesohigh?

[greg_kfdm_tv]

What's a mesohigh?

This is also commonly called a "bubble" high. It is created by the rain cooled air behind a cluster of showers and thunderstorms. The pressure rise is also assisted by sinking air in the wake of the storms.

Hope that helps.

This is just normal convection nothing going to develop.

I usally look at what the pressure was 24 hrs. ago to see if pressure is rising or falling, if you use that as a rule ( not law) it might help.

Good point. Overall on Satellite it looked on its way earlier. It has since collapsed. Was an interesting feature as it held together for the last day or two since leaving the coast.

Are of low pressure forming at 24.5 83.3? Has the distintintive hook on visible

SW winds at one buoy last 2 hours and another just now reporting SW winds. Thundrstorm related or? LEts see.

Key West has had south or southwest winds all morning.

[Starburst]

If I am reading the buoy data map right on accuweather they are reporting a pretty substantial pressure drop in that area. Maybe someone that knows more about buoy data can verify this.

I'm not seeing anything but steady pressures in the Keys and in the eastern Gulf. What bouy were you looking at?

THE RIDGE AXIS WILL
BE ACROSS SOUTH FL AND THE FL STRAITS FOR SAT AND SUN. THIS WILL
CAUSE WINDS TO BECOME SW AT THE SURFACE WITH THE STEERING FLOW
ALSO INCREASING FROM THE S/SW AS THE UPPER TROUGH DIGS INTO THE
EASTERN US SAT AND THEN REMAINS IN PLACE SUN.
