Florida, the Sunshine State, continues to be the thoroughly sodden state, thanks to torrential rains from slow-moving Tropical Storm Debby. On Monday, Debby spawned an area of intense thunderstorms that blew up over the Florida Panhandle, just east of Apalachicola. A weather station in Wakulia County, 4 miles east of Saint Marks, Florida, recorded 12.99" on rain in just 12 hours, bringing the 48-hour rainfall total at the site to 20.96". Several other stations in Wakulia Country also recorded rainfall amounts in excess of 20 inches, and the heavy rains caused moderate to major flooding on area rivers. Debby did not spawn any tornadoes on Monday, thankfully.


Figure 1. Radar-estimated rainfall from Tropical Storm Debby shows an area of extreme rainfall in excess of 15 inches has affected the Florida Panhandle.

Dry air and high wind shear continue to disrupt Debby. Our Wundermap for the surrounding ocean areas shows that winds at almost all buoys and coastal stations along the Gulf Coast were below 25 mph at 7 am EDT. Visible satellite loops show Debby has virtually no heavy thunderstorms near its center of circulation, which will severely limit its potential for intensification. The heavy thunderstorms of Debby are mostly on the east and north sides. Upper-level winds out of the west creating a high 20 - 25 knots of wind shear that continues to drive dry air into Debby's core. This dry air can be seen on Water vapor satellite loops. Ocean temperatures are about 27.5°C (81°F) in the Northern Gulf of Mexico, which is about 1°F above average, but these waters do not extend to great depth, which will limit how strong Debby can get.


Figure 2. True-color visible Terra satellite image of Debby taken at 12:30 pm EDT Monday June 25, 2012. At the time, Debby had top winds of 45mph. Note the heavy thunderstorms on the north side of the center, which were dumping extremely heavy rains over the Florida Panhandle that caused major flooding on area rivers. Image credit: NASA.

Forecast for Debby
Debby's slow motion will make rainfall the primary threat from the storm, though tornadoes will continue to be a threat over the next few days. NOAA's Storm Prediction Center has placed most of Florida in its "Slight Risk" area for severe weather today. The slow motion of Debby will inhibit intensification of the storm by stirring up cooler waters from the depths to the surface. Debby's close proximity to land places a portion of its circulation over land, which will also tend to slow down intensification. Wind shear is expected to remain in the high range through Wednesday, and given the storm's other problems, significant intensification before landfall on Florida's Gulf Coast is unlikely.

Denver's 105°: hottest temperature in city history
The mercury soared to 105° in Denver, Colorado on Monday, tying the record for the hottest temperature ever measured in the city. The city also hit 105° on July 20, 2005 and August 8, 1878. Yesterday's 105° reading was the city's fourth consecutive day in the triple digit heat. The city's record streak of 100°+ days is five, set in 1989 and again in 2005. Denver's forecast today calls for highs of 100 - 104°, so the city will likely tie its all-time mark for consecutive 100°+ days.

In many respects, the extreme heat that has scorched Colorado since Saturday is the state's most intense heat wave in recorded history. According to wunderground's weather historian Christopher C. Burt, Saturday's 114° reading in Las Animas tied for the hottest temperature ever measured in the state of Colorado. Two other 114° readings have occurred in Colorado history: in Las Animas on July 1, 1933, and in Sedgwick on July 11, 1954. Colorado Springs tied its all-time record for warmest temperature ever measured on both Saturday and Sunday, with readings of 100°. The record heat in Colorado has exacerbated numerous destructive wildfires, and the Governor reported over the weekend that half of the nation's firefighting fleet has been deployed to Colorado. On Sunday, a wildfire that grew to more than 3 square miles near Colorado Springs drove 11,000 residents (2% of the city's population) out of their homes. In Fort Collins, the mercury hit 102° on Sunday, just 1° below the city's all-time hottest temperature of 103° set on Jul 21, 2005. The heat did no favors for firefighters struggling to the contain the massive 81,000 acre High Park fire fifteen miles northwest of Fort Collins. The fire is the second largest and most destructive wildfire in Colorado's history, and is 45% contained. La Junta, CO hit 110° on Sunday, tying its all-time hottest temperature record, set on June 28, 1990. Today is the last day of exceptional heat for Colorado, as the ridge of high pressure responsible slides to the east, bringing record-breaking heat to the Midwest instead.

Looks like we have a new player in the central Atlantic. That little blob has a nice spin to it, it even has convection near its COC. And no shear to boot! It would be just too funny to get storm #5 before July 1st. What a record that would be!
Saw the same thing as soon as visible imagery was available this morning.

Large COC makes it kinda hard, but Debby appears to be moving just S of due E. Probably a temporary movement before a due E track starts.

Wow.

Storm has moved 0.1E and 0.1S since 1a.m.

That's just about ONE mile per hour if diagonal, or 2 miles per hour if it did a stair-step...

On the possibility of a later loop back to the west...if Debby manages to slide south far enough, that west loop becomes more likely as the trough would be more likely to leave it behind the further south she is. So that is something to watch for, any south component in the motion. If it is starting soon, it could add up to significant difference in latitude at the critical recurvature-or-not-recurvature time.

Debby at 21 hours.
In alot of ways Florida was fortunate with Debby, what if she was alot more organized and then stalled over Land you would be looking at record flooding and more loss of lives.

Quoting Neapolitan:
I lived in both Colorado Springs and a suburb of Denver, and there was definitely a mini-monsoon season, one with lots of very wet thunderstorms (and more than a few hailstorms). These mostly seemed to occur with the Southwest monsoon that gives the Sonoran and Mojave deserts much of their rain. But if the synoptic-scale hot/dry pattern sets in and becomes large enough to become almost self-sustaining, the area may not experience a "normal" summer rainfall pattern.

Keep your fingers crossed...
One Summer I spent a week or so in Denver and it stormed every afternoon, saw hail a couple of times. Hope they and the other states like NM and Texas plus others get a little relief soon, temps around 110 are tough on people and animals.

It appears that the center has been adjusted to be more south since yesterday...?!?!? The official movement is due East, but I've seen some posters saying it's drifting SE... I live near Orlando and we've already been deluged with rain... long-time lurker and appreciate all of the valuable knowledge and insight on this board!



East movement with a Southward drift is correct, she is south of the forecast points. Not much left of Debby at the moment however.

How about that 12z BAMM track...over the FL peninsula into the Atlantic, the loop back over the peninsula into the Gulf again. 12Z BAMS is similar.
Debby the Defiant is giving serious consideration to those tracks.

I think i just saw that we have the highest probability of el nino since 04.
But was that a shortlived el nino in 2004, because 2004 and 2005 were both very active hurricane years.
I cant seem to recall what the el nino/la nina situation was like so long a ago.


El Nino or no El Nino, in 2004, we got spanked back to back with Frances and Jeanne in S. Fl in September. Add our very wet spring pattern (which we had in 04) and I am now getting very nervous about a repeat of that season. Again, all it takes is 1 to hit to ruin your day, but 2 hitting 3 weeks apart was just plain mean. Mother Nature must have a sick, wicked sense of humor!

Colorado does have a monsoon season coming very soon. My understanding is dry thunderstorms caused some of their fires well soon they will have wet thunderstorms that should help. Near 110 here today, it was 105 yesterday with 42 days without rain. Lots of fires here from those who are throwing cigarettes out their car windows.

Based on the latest recon vortex message, I would be surprised if this is still a TS at 11am. Unless they find some stronger winds somewhere. No deep thunderstorms around the center, shear, dry air really taking their toll on Debby.

You're there? Wish I was; I won't be back in until tomorrow afternoon, then I'm off in another direction three hours later. But, hey, at least I'm working, right? ;-) What are you hungry for? Naples is loaded with restaurants, of course, being a tourist town. Of course, while it's not as bad as it used to be, it's a wintertime tourist town, meaning that some (many?) eateries are shut down for the summer--though it's far easier to get a seat in the ones that are open.

Radar says there's a small line of storms sort of training through there this morning; stay dry.

Well, I would not be so quick to rule out any kind of climate change for our planet. No, I am not one of those chest pounding, doomsayers, but....

Our Earth has gone thru extreme climate changes of millions of years...hot & moist, ice age, continents breaking apart, oceans & lakes created and then turned to deserts. Yep, she does change. Proven scientifically.

Maybe, just maybe, we could consider than there are subtle changes going on and all our fancy computers and such may not have all the necessary information to make a correct call. Just looking at all the confusion and debate over Debby and wondering why she is still out there, not really moving after all the models (logically) called for her to get picked up by trough or grabbed by ridge and then move rapidly away either east or west (pick your favorite). Chris formed in COLD water and became a HURRICANE and defied tradtion/logic. Again, just some thoughts.

I love this blog and have learned so much, but have also learned sometimes you just can't outguess Mother Nature!! LOL
