First time I've seen a system show up this season.

EPS has a signal too.  Something to watch as the fronts spin up their tails.

This idea is back today

Another one to watch - seems small but you never know.

NAM isn't biting.  Euro has a signal for it. CMC gets to a center of circulation but moves it inland, as does Icon.

18z GFS is pretty active with lps off the coast.

This one looks more subtropical as it develops and sits off New England later on.

The above low heads NE again and another one forms

Euro has the one off NC in a few days and this one out further

Pattern is right with High pressure swinging through the NE

The bottom one is the feature from Monday's post.

I don’t watch the news that often and was surprised when CBS said our first named storm could form and hit FL this weekend. NHC is not all that enthusiastic   image.thumb.png.638e42ac8328b4c46734b563a8f436c2.png

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Wed May 31 2023

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. Northeastern Gulf of Mexico:
An area of low pressure has formed over the northeastern Gulf of 
Mexico in association with disorganized showers and thunderstorms 
displaced to its northeast. Environmental conditions appear 
marginally favorable for some slow development over the next day or 
two as the system meanders over the northeastern Gulf of Mexico. 
However, by this weekend environmental conditions are forecast to 
become unfavorable for additional development as the system drifts 
southeastward towards the Florida Peninsula. Regardless of 
development, the system could produce heavy rainfall and gusty winds 
over portions of the Florida Peninsula through this weekend. 
Additional information on the rainfall and flooding potential can be 
found in products issued by your local National Weather Service 
forecast office and Excessive Rainfall Outlooks issued by the 
Weather Prediction Center.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.

Good advice from Dr. Cowan

The GFS has been consistently showing it and admittedly, with a ridge moving north into Texas, I do see an opportunity in the Western Caribbean. Wind shear has been downright aggressive in the Caribbean so far this season, but that should abate some in the next 5-10 days. The GFS wants to go bonkers with a system, but to Dr. Cowan's point, not completely logical. It is more likely that nothing comes to fruition, but I can see a window opening if a system can come together. 

The question I have is where does the heat go from Texas? The GFS continues to want to loop cutoff systems into the northeast, while the Euro is showing signs that maybe that's not correct following the current system that is going to move north, loop, and provide much needed rain to the Mid-Atlantic and NE. I think we might see heat dragged due north into the plains with some 90's and low 100's late next weekend up into Eastern OK, NE, and KS with the heat then starting to push east. That should collapse pretty quickly, but we probably will get storms riding the contours. Eventually, in July, with El Nino now firmly established, our ridge should retrograde into the Southwest.

While the GFS is drawing attention for constantly making cyclones (like the CMC does), the Euro has been criticized for missing them in the formation stage.  So when the GFS and the Euro each have something, it's probably going to draw the attention of the NHC, although climatologically it's pretty rare.

This is pretty much it for June

Thats cool will have to bookmark that site then. The Atlantic may be firing off storm after storm coming up in the next two weeks. This is really impressive for this early in the season and at that producing Cape Verde systems in June is extremely impressive, this area doesn't typically let its guard down until end of July early August.

Would certainly be something to see not only an average but potentially above/well above average season while forecasts are still for a strong to even super El Nino forming. We are living in some interesting times coming up.
