We started talking Monday about the potential for homebrew this weekend and now we have a seedling off the west coast of Florida.
The visible satellite shows what looks like a mid-level circulation with a complex of thunderstorms. This area is related to a stalled frontal boundary, which is a climatologically favored way for homebrew development this time of year.
The environment is marginal, but in my estimation more favorable than what we saw with our first and only TC of the season so far, Arthur.
The area its expected to traverse is one of the warmer spots in the Gulf relative to normal.
Looking at Euro and GFS analysis, while there is modest dry air lurking, moisture seems to be present enough to allow for convection to fire should this want to organize.
A true limiting factor eventually may be the presence of shear to the north, but at the moment that is not hindering today's convection.
The biggest factor IMO on whether this is able to develop, is how much time it has over water. This area is in a location trapped between a ridge in the Gulf and a ridge in the western Atlantic, which should allow it to meander for now. However, as a trough swings in, that will open a path for this to get shunted north/NNE. If that happens, development will be unlikely. The GFS, which has been far less bullish on TC genesis chances from the very beginning, shows this well.
However, if that trough is not able to turn this area quickly, it could get trapped under a building ridge in the wake of the trough, pushing this further west and keeping the window for development open long enough for genesis to occur. The Euro AI has been most bullish on this scenario.
The ensembles have waffled back and forth, but this season I've been putting more stock into the AI ensembles and GDM (Google DeepMind). You'll see a modest signal below from both the Euro AI and GDM, and the further west the low tracks the better the chance for development.
So today it's worth watching how this area off the FL coast tries to fire persistent convection, and if it can organize as a result. This weekend the trends on track will be crucial to whether we see homebrew development or not.
