Invest is up now. We should get the first HWRF run in a few hours.

Glad to see we'll have some tropical models to work with here soon. Should help provide a bit more clarity about the outlook for this disturbed weather

12z Euro is coming in a little stronger, and develops it a little quicker than previous runs.

12Z Euro is 1MB weaker and more of a NE trajectory in the Eastern Gulf with landfall between Cedar Key and Tampa.

Also the vorticity doesn't look as strong as it is getting stretched out on its approach to Florida similar to the GFS.

This forecast is about as straightforward as they get for a disturbance. North to the Gulf then NE to a bit north of Tampa, with landfall of a sheared TS on Tuesday morning. Main threat is heavy rain across Florida. could be a small area of 35-40 kt winds, but average onshore flow 20-30 kts.

Feels weird to get model runs like this in June... Looks like something we would see in September or October. Looking at that spaghetti plot, my first thought was "Wilma".

Main threat is heavy rain across Florida. could be a small area of 35-40 kt winds, but average onshore flow 20-30 kts.


What are you thinking about for tornadoes in the southern half of the state? Looking at a 50+ kt LLJ in the models.

SST's are plenty warm in the entire Gulf of Mexico.

At the beach right now and the water literally feels like a huge bath tub! Has to be a degree or two above normal for this time of year on the SE FL Coast. Any warmer and it would be too uncomfortable to swim in for too long. :lol:

12Z Euro is 1MB weaker and more of a NE trajectory in the Eastern Gulf with landfall between Cedar Key and Tampa.

Also the vorticity doesn't look as strong as it is getting stretched out on its approach to Florida similar to the GFS.


What I am seeing is stronger than last night's run, it even shows stronger winds for the FL Peninsula, through wunderground site.
