Tropical Storm Debby makes landfall in Florida

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.

The first run of the new GFS is showing a Low in the vicinity of the wave.

This is why we need a decent Tropical Wave to at least aliviate what we are going thru and that is why I am rooting for that wave to bring good moisture to the NE Caribbean.

Texas has the weirdest weather in the United States. Snowstorms and frigid temperatures in the winter, warm and tornado outbreaks in the spring, very hot and sunny in the summer, and rainy and warm in the fall.

Well,a number of people asked me to do a blog last night. I did one early this morning and not ONE of you even looked at. So now I think I will keep you all in suspense about those suspicious waves.:)


Now if you just read your responses to your blog and comment on them that would be OK with me..:p
Don't worry about me as you have my respect.. :)

It did a few runs back. There has been plenty of storms that formed the gfs didn't develope. GFS isn't Gospel lol


I know.......We will have plenty of ghost storms this year, like every year, from the various models but I will be curious to see how GFS performs for the rest of the season or if Debby as a "lucky" guess.....

Changing to the wiki background would reduce the amount of raw data available. Remember, WU focuses on more data, wiki is more on asthetics. Kinda like how a Toyota Corolla is designed for people who just want to get from point A to point B. A Lexus IS is designed for a completely different audience.


it can be done, everything the WU background has can be recreated on the Wiki map, it is mainly just borders and lines.

Even though there is a lot of SAL out there, especially near the Antilles, a lot of models do not give it as much weight as they used to. The current system in the Atlantic looks like it is trying to create its own moisture field. SAL can defintely have an impact on a system, but it also depends on the height of the layer field and the strength of the system.



its moving the sal around it

Another startling view from Colorado Springs last evening as the firestorm was near its worst. Oh, man...

fire

The worst fire in Colorado Springs history--and one of the worst in Colorado history--takes place on the hottest day in Colorado Springs history.

Or where Cat1 changes to Cat2?

in GA the water past a certain point in the piping system heats to 100+ but the water from the deep in the pipes and the water system is quite cold to the touch after a few minutes.

Maybe since GA trounces LA, we even have a better water system

we layed down on the pool deck and poured water on ourselves.
They tried running freshwater from a hose into the pool allday.
Its like putting a syringe of icewater into a hot bathtub.
Hot as hell.

Good Morning. Looks like things will be quiet on the tropical Atlantic, with the exception of the remnants of Debby moving off the coast, side per the most recent GFS run. Just saying......... :)

Also interesting to note the current positioning of the A-B high; some pretty strong ridging out there at the moment between Africa and the Caribbean. Have to see how this pattern will change, or not, once we get into the heart of the Cape Verde season in August-September.

Well looking at the NHC radar out of Melbourne it looks as if Debby is ESE of St. Augustine just NE of Cape Canaveral.In the discussion it mentions it's possible she may get left behind by the trough on some models. If this is the center she is still moving ESE, but if they can't tell where the center is, I'm sure I can't either. Just for discussion sake hope she's in no mood for a Bahamas vacation.

We should know within a day or so what our AOI will do, when it detaches itself from the ITCZ (I think it is very close to doing so and looks quite impressive with this in mind). Also, dry air across the CATL has lowered significantly since last night, and it appears that wind shear also will not be an inhibiting factor for our wave. A third noteworthy item is that, while the magnitude of vorticity is not huge, the wave is nearly completely stacked with an impressive amount of spin. The only thing that is preventing me from outright predicting cyclogenesis is the fact that it is still June, and we are talking about a wave that is closer to Africa than the Islands.

WU is clearer, but much more harsh on the eyes. Wiki is more attractive, but less clear. They are designed for different audiences.

WU - weather nuts, people more concerned with detailed data.
