Why haven't we had aft thundersorms this 2005 summer

[boca]

The aftternoon and early evening thunderstorms haven't materialized in the last 2 years here in S FL.I don't have a clue why but if the pros have some insight that would be greatly appreciated.

Good Point!! We too haven't seen near the number of summer tstms this year as in years past. In fact, I don't think I can recall the last one here...

This shouldn't be in the tropics section, though...

Yeah, but your avatar is worth it!

But it is odd, we have a grossly short supply of afternoon thunderstorms,
and we have 5 GOMEX majors. Coincidence or correlation?

here in central florida we had our regular afternoon thunderstroms just as usual

Gotta be a correlation in there somewhere. Seems to me this is quite a good topic for the Tropical Board as it presents an opportunity to explore yet more weather-related phenomena that may connected to this year's unusually high tropical result.

HMMM... just a thought:
South Florida has two hurricanes affect it, hardly any t-storms
Mississippi: has a major hurricane hit it, hardly any thunderstorms
NC: my area gets affected by hurricane ophelia, before, no t-storms, after, we get dumped on...
VERY interesting to say the least, what about LA and Northern texas, guys?

see, and central fl didnt get affected AS bad, so they have their afternoon t-storms, hmmmmmm...

[terstorm1012]

that is a very interesting correlation......there's gotta be some research somewhere on that. off to google i go

LOL, ok, if ANYTHING turns up, let us know....

I was just saying to my husband, How come we haven't had our regular afternoon thunderstorms for most of the summer? Normally in the Tampa area, we get these wicked-awful thunderstorms in the afternoon or evening, terrible lightening, dogs freak out. But they stopped in July if I recall correctly. Hmm.

[Crankin]

Yeah, Mountainspring, but no hurricanes for us in Tampa...yet. It almost sounded like lack of thunderstorms in the other areas correlated positively with hurricane strikes, but not in our area.
Did summer 03 have regular thunderstorms in FL? I think so, and look at what we got.
I say there is no relation.

Afternoon-Evening Storms in S.FL only occur in a W or SW steering regime that bring in storms from GOM inland and also cause the seabreeze convergence to occur on the eastern part of the state. Of course this year we have been under the influence of some strong ridges and the steering this year has been dominantly Easterly and South with instances of NE winds favoring SW Gulf Coast and interior florida storm activity in Afternoon-Evening and Eastern florida showers or storms late in the evening and early morning.

You can read these examples from NWS discussions for S.FL region. Also Tampa is further north and is in the higher heights of the ridge which supress any activity from forming. We should see some more instability as fronts come in and create instability before we shift to the dry-season pattern and PWATs and Dewpoints decrease to low levels.

Latest discussions show that PWATS and dewpoints will begin to generally decrease around the state as shortwaves move in and the ridge moves W, putting us in a N to NNE flow. Indications of this progressing shuts the doors down on homebrew systems in the bahamas as a more dry airmass sets up due to the seasonal climate shift we are commencing.

We have had our share of thunderstorms here also. Last year we didn't and we got hit by 2 hurricanes.Maybe there is something to this, makes you wonder???

Absolutely correct.
I think we had a normal amount of afternoon/evening thunderstorms when all is said and done; a lot early in the summer and not a lot late in the summer
Look at the rainfall totals this summer, they were very close to normal.
In fact, many of you were complaining a couple of weeks ago about all of the rain that we had in South Florida and how we could not handle anymore.
I kept pointing out that we were close to normal.

Here in SE Fla we DO NOT get a ton of afternoon/evening thunderstorms. Not like the West Coast does.
As hard as it may be for many of you to admit it... this was a pretty normal summer.....
The anomaly were the Bahamanian born storms that moved across extreme SE Florida/The Keys; beyond that ....very normal.... on all fronts.....

[Ixolib]

Perhaps for SE FL, I agree - but certainly here on the north-central gulf, we typically have afternoon tstms every day (or almost every day) in the summer. And even with the persistent easterlies in some years past - similar to this year - we even had quite a few "backdoor" storms. But not this year. Either that or Katrina's aftermath here has just completely erased my memory of anything pre-08/29. Actually, that may not be too far off the mark.

In any event, I kinda miss the good 'ole wx patterns that I've come to know and love...

Thanks for the compliment. With the way this season has been going, I've had to update it non-stop! Anyway, I didn't mean to come off as harsh with what I said earlier. I just hate to see things posted in the wrong place. But now that you mention it, I see how this can relate to the tropics. I guess I can be a backseat moderator at times, even though I shouldn't be. My bad.

Personally can't speak for the normal weather pattern in your area.
I was responding to the author of the thread who lives near where I do.

[Terry]

We often get the "reverse flow" in Central FL, so I'd assume you in SE FL could also get the weird wx pattern.

Oh, wait. I grew up in SE FL in the 50's and 60's and remember such changes...... early morning thunderstorms, late afternoon thunderstorms, no storms, lots of hurricanes...

[Brent]

We had MORE than normal in June and July... and much of August. We had our normal entire summer rain by then and then, after Katrina, we had no rain for 3 weeks... strange.
