gfs looks to take a broad low north of tampa then onto jax...but could it be tropical? either way looks stormy on tues.

Last night's run gave heavy rain to pretty much the entire peninsula. That makes me happy as it will get water into Lake Okeechobee before the dry season. Usually southern Florida is pretty dry during winter during ninas.

Last winter was bone dry. It started with Nicole lol and did not break really until mid and late June. There were many municipalities contemplating banning fireworks on the fourth. Being a legal state, that would have went over well. laugh.gif

I know, the lake was really low by mid April. Lots of boats needed prop work.

Hey Ice,

Do you think we will get any action down here in the next few days? I know NOAA has a cherry south of us.

It depends on what you mean by action. I think if anything tropical, or subtropical forms in the Gulf, it would make landfall too far NW (panhandle or big bend region) to have much of an effect on us.

That said, Miami radar VWP profiles indicating lots of deep-layer veering, and cells are beginning to become increasingly isolated south of the keys. The trough digging south tomorrow should only aid in forcing upward motion and increasing severe chances further north. I wouldn't put it out of the question that we see a tornado or two over south FL tonight, with the greatest risk shifting northward to include all of FL tomorrow.

Woke up today expecting to be inundated with rain. So far as of 1PM nothing even remotely close to Ocala.

This could be the first time ever that a 100% chance yields nothing. stun.gif By 100% I mean sunrise to sunset.

I was at 70% and it rained all day. Go figure. NOW I am up to 80% lol

That squall line coming onshore in the SW has its eyes on MBY. Along with the tornado watch till 10PM.

Good for you. Glad most folks got something out of this. Looks like that convection moving towards the lake may be pretty intense. Quite jealous up here.

Well it's sunset so its official. A 100% rain chance was a bust with not a drop. There is some lame convection to my west so I guess .10 isn't out of the question but that will be later.

Kind of sucks because the chamber of commerce weather kicks in tomorrow afternoon. 72 and sunny for the next week. Booo!!

Watch out in West Miami, North Miami and Ft. Lauderdale! The couplet has weakened but if that thing could cycle!

00Z sounding indicates 444 m2/s2 sfc-1 km helicity. Looks like new cells are beginning to fire over the far southern tip of the peninsula. Any cell that can maintain an updraft in this environment has the potential to produce a tornado. Stay safe!

Storm is just to my south now but looks like it will pass just to the west of me. Impressive looking on radar right now.

A crazy last three hours and full day on the Treasure Coast! Tornado warnings just to my north and west by mere miles, a flat out DELUGE for three hours, and wind gusts up to 45 knots that capped off a day that saw steady light to moderate rain since day break. October IMBY is already approaching freakish territory and all of it without the help of a named tropical system.

Edit ... tornado watch extended for MBY until 6 AM. More rolling in from SW FL.

very strange...watched radar all day [10/18] because of already[last week] washed out roads in polk county...seems there was something stopping the heavier rain from going north of a east-west line from vero to st.pete....

It's pretty impressive that the Sunrise tornado was rated EF2. The couplet was much stronger out over the Everglades, so its a good thing it didn't hit anything or we could have been hearing about EF3/4 damage.
