Tropical Storm Debby makes landfall in Florida
Posted by: Angela Fritz, 09:07 PM GMT del 26 Giugno 2012 +39
Debby continues to weaken this afternoon, but remains a tropical storm with maximum sustained winds of 40 mph. The storm's center of circulation made landfall this afternoon near Steinhatchee, Florida. Hurricane hunters continue to find surface wind speeds that just meet tropical storm criteria and surface buoys on Wundermap are all clocking in at or below 30 mph. The storm's upper-level circulation is being stretched out into the Atlantic by the same steering forces that will transport it to the other side of Florida, and this combined with dry air has led to a messy-looking tropical cyclone over the past couple of days. Though there was no lack of rain yesterday in the Florida panhandle, Debby has certainly been weakened by the dry air that has wrapped into its center (figure 1). Water vapor imagery from satellite shows Debby's center is almost completely void of moisture, though rain continues to fall on the northeast side of the storm where moisture is still available. A 6 foot wide, 12-15 foot deep sinkhole swallowed a small portion of I-10 in Madison County west of Jacksonville, Florida, this morning, where heavy rain continues, though this hole will likely be filled and the lane reopened by tomorrow morning. Wind shear around 20 knots is also keeping Debby at bay, but the real disrupter is the lack of moisture.


Figure 1. Where's Debby? On the left: visible satellite imagery. On the right: water vapor satellite imagery, where the dry air ranges from black to rusty orange. Debby's center is almost completely void of moisture. These images were captured around 1pm EDT.

Forecast for Debby
The forecast for Debby continues to be similar to previous forecasts. The storm will likely continue to lose strength as it moves over Florida this evening and Wednesday, but could gain some momentum again when it reaches the yet untapped Atlantic water. There's a high chance Debby will be downgraded to tropical depression status this evening. The HPC continues to forecast up to 8 inches of rain for far northeast Florida over the next 5 days, likely because of the slight strengthening forecast to occur on Thursday and beyond. Debby's center will most likely be over Atlantic water Wednesday night.

The Heat Continues

Record highs continue to fall Tuesday afternoon in the central U.S., where Denver, Colorado had its fifth consecutive day of triple-digit heat after it reached 100°F at 1pm MDT, and could continue to rise this afternoon. This ties the all-time record for consecutive 100°F+ days. Nebraska and Kansas are particularly toasty this afternoon; McCook, Nebraska has reached 113°F so far, and Hill City, Kansas is up to 112°F. Though, to put that in perspective, the state record for Nebraska is 118°F, and the state record for Kansas is 121°F.

The heat moves east tomorrow, and by Thursday, many of the major Midwest cities are forecast to be in the triple-digits, including Chicago, St. Louis, and Indianapolis. By Friday the heat will be beating down on the East Coast. In the meantime out west, the forecast high in Fresno for this weekend is 82°F, which would tie as the coolest final weekend in June on record, according to the Hanford forecast office.

Quoting weatherh98:

it looks extratropical

It looks generally awful, lol... Yesterday I was thinking we could get a decent bit of restrengthening after it reemerged, but at this point anything beyond a 50mph peak seems unlikely... The trip across Florida took a toll on it, and it wasn't too well organized to start with, so it won't do much.

Strange. Shows it every other time I refresh.


What is it we can't see? If you can't see it, how do you know it's there?

no way, i overheated today in swim practice.
you would have to sit almost still in the pool to cool down

to put it perspective, it is warm enough to feel warm when you jump in, practically as warm as or warmer than the air.

average skin temp is 31-32 C for someone who has been indoors, or about 87-89 degrees, and the water has the potential to quickly transfer heat to your skin, given it is 90F or warmer

This morning in N GA the water in our pool was 90F, and will only get warmer

just think, you sweat in 90F weather, now imagine water.
It is not a pleasant experience

Very interesting graphics. So, if I'm understanding that right, although SSTs are (so far) unspectacular this year, the temperature at depth is unprecedented.

I assume that this means that hurricanes which do form have a better chance of becoming majors.

Hi Again ...

Seems this is the best/only 'path' here for Tropics/Hurricanes, yea ?

If so, then guess I'm in the right place ;-)
.

Now, here's a good one some Folks been playing with ...

Quoting Tribucanes:
Best weather should include a state that experiences all four seasons.


.
Yes, happy to see so many standing up for their 'States Rights' (so to speak ;-)

But let's think of 'Areas and Regions' ... or maybe Geographical Climates Zones

(or is there an 'Official Term' for this idea ? ... and sorry, been a while since I talked weather with Real Meteorology Types, and I may sound like Bubba Gump from Gumpstump, so hope you'll forgive any shortcomings I have in those regards)

Do know the Northern Gulf Coast/Deepest South ... from oh, say Houston across to Jacksonville, something like that. Some call it the "Northern Boundary of Margaritaville", but that's only if you consider any Changes in Latitude might affect the Attitude (smile)

This Area, and correct me if I'm wrong, has about the Widest Range of All Possible Weather Anywhere. Won't necessarily get it any given year/cycle, but over the long run. About same for all of Eastern No.America too, yea ?

And are many in my direct area who claim, as the Chamber of Commerce would insist - Tallahassee, the Place Furthest South that Gets All 4 Seasons

Well, can, but not every Season every Year to the degree of that 'page turn' Up North ... that CAN happen, just not year in/out

But, is about same across this whole 'Area of North Gulf', yes ?

Do your own Math on all this, but has something to do with it as the 'Tail End of the Appalachians' ... good example is the 'Escarpment of the Old Spanish Trail' (now I-10, Hiway 90 across Panhandle), Caverns at Marianna, etc .. was some type of 'island' (in a sense) during last Ice Age, so many trees survived that are now gone in rest of South and won't find them till get to way up North - Elm, other Hardwood good examples (and something else going on with the very unique Torreya Pine, cousin to Torrey)

Yep, Snow, Tornadoes, Hurricanes, Afternoon T-Storms with lotta Lightning, etc etc ... get it all, and at times can get a LOT of it all

As one Ol' Weather Guy used to say, and he was Col. in charge of Eglin AFB Weather Command yada way back when ...

"Every Meteorologist in Military wants to get stationed at Eglin. Is THE Place for Weather on Earth"

Or something like that, but you get the Idea, and Quite a Boast, eh ?

But, he was serious Old Skool from Penn State ... yea, that place ;-)

And think Fla State Univ now trying to gain that same reputation ?
.

Anyway, all across this Northern Margaritaville ... sure is something going on almost all the time ... weather-wise ... so grab any State along here, all of them will 'work' ;-)
.

Now, this 'Big Front' that's just moved through, and moved out Debby

Maps I'm seeing show it's moved all the way to Key West, yes ?

Again, another Front getting this far South this late in year, not too common as I know the 'history' .. that fair ?

And like I was yappin' here earlier, let's see what gets left in its wake, yea ?

Could get interesting again in next week or so ?

Ok, ty all, later, BC
.
