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.

It is times like this that I wish the Houston adage about our weather was true... "Don't like the weather? Wait 5 minutes, it will change."


They say that here in Colorado too. I heard it growing up in Cincinnati, Ohio as well. In fact, I did a little research one day and came to the conclusion that the "If you don't like the weather just wait x minutes" adage is common for just about any place with a temperate, continental climate.

As for our weather along the Colorado Front Range, adages notwithstanding, I don't expect much change for at least 10 days out. It is currently 103 F and climbing at Davidson Mesa near Louisville. Humidity is a lousy 11% and winds are gusty and erratic. But hey, at least we have a few clouds around today.

Ya those lake have been forming earlier and earlier and now they're getting larger. Watched one that was seven miles by twenty with a decent depth I want to say of about eight feet disappear in a matter of minutes as a fissure opened up. Scientists fathom that all this water rushes to the bottom and makes the shelf move faster and faster as the situation exasperates.

looks like the new norm for texas, one more year and texas might be the new nevada.....


Look at the global patterns and how the airflow patterns are but it is quite obvious that just like there is a tropical flow there is a dry flow. The Sahara to the American dessert. And look at a topographical map of the US and you will see the dessert advancing from the pacific Ocean to the Gulf coast of Texas. Central Texas has been transitioning for years now and its going to continue unless there is a global climate change like there was 10,000 years ago when global climate changed and created the desserts. I do not now the effect of GW on this and hate to bring it up but you think it would speed this process up.


Back on topic Debby looks like she is flying compared to the past 3 days even tho she is still moving pretty slow. I fill bad for you Floridians and I hope everyone stays safe.

I agree. Too many children come on here and try to establish themselves as "good forecasters" as a status symbol. All they end up doing is driving intelligent people away from the blog, irritating the other children (who then get into an e-peen match), and getting on everyone elses' nerves.

Is there anything to prevent Debbie from going south once she emerges out over the Atlantic? I would sure hate to see her go south then back across the state.

There isn't anything to really drive her south or back west, as there is a high pressure pushing her east, and the A/B high will push her north.

have those lakes been forming in the past during the summer, or is this a recent development?

They have been forming in the past during the summer, but earlier and earlier each summer.

Debby was/is a very "frustrating" storm to forecast and it brought out the best and worst out of the models and humans as well.......Model divergence when a storm has not formed, or is way out to sea, is one thing. Model divergence, and other uncertainty, when a storm is on your doorstep is another and Gulf storms are some of the toughest ones to deal with.

I can't remember how many times we have seen the "cone" keep shifting to the left on an incoming Cape Verde storm heading out of the Bahamas towards Florida and the Gulf. Everyone "waiting on the expected turn" as the cone shifts West from South Florida, to Big Bend, to Panhandle, to AL-MS, to LA and so on when ridges and weaknesses do not materialize exactly as predicted in earlier model runs.

This experience with Debby illustrates why this is not a perfect science yet; and may never be.

yeah it does, but thats the closest ive seen convection to the center since it first developed! i think it will look better once it hits land and the day time heating really fires the storms around the center, probably will help it when it makes it into the atlantic!


I agree. Being that part of the inner circulation is already brushing the coast, watch for convection to fire close to the center very soon.

Yeah 107 here with no wind. Thankfully there's almost no humidity otherwise I'm pretty sure the pits of hell would be showing themselves.
Don't worry hottest part of our day is yet to come, the all time high of 112 in Austin could be in jeopardy since the hottest part of day is between 4 and 5 pm? Some records will fall, the bad thing about this heat wave is No wind at times in certain locations. I was on a metal boat on a Lake early yesterday morning with the No wind, no ripples at all and I baked for 3 hours, I have been fishing this Lake for over 30 years with a boat even when it is hot but I have never seen it that calm or that hot.

Yesterday and again today, I'm backing my car into the garage so the hood and engine is near the garage door so whatever heat can escape out, instead of being deeper inside of garage near the door and inner wall.

Yep. I just moved to a new office building this week (now closer to the Memorial area), and I have access to a parking garage now... It is AMAZING how much difference it makes.

Just something to think about.. alot of us Meteorologists and people in general living on the west coast of florida from Venice to Panama City are very thankfull that this storm did lack moisture. Sure alot came down on Saturday and Sunday in extreme western florida and in Apalachicola on Monday..but this is such a slow mover that the rainfield could of been alot more than squalls of showers coming in for most of the State. There is a tornado threat but the dynamics are slight now. But I'm talking about rainfall..especially in the Tampa Bay area.. there was Alot of Rain early on Saturday into Sunday. The Flow off the GOM is surging water over its banks in S Tampa and St Pete,.. if the normal TS had the moisture field with it... the area from TampaBay north to Cedar Key would be approaching 25-40 inches of rain in 4days (Sat thru Tues).. So in all, this could of been a whole lot worse for West Central Florida coastline. We saw what St Pete- Clearwater got on Saturday, We saw what Apahalcholca got on Monday.. think of it as if this system didn't have dry air in it.

Looks like Debby is finally about to make landfall south of Cross City, Florida (sometime later today at least as the cold front starts to give her a kick). The 26" of rain with Debby in Sanborn is incredible, hopefully we don't see anything like that as she slowly moves eastwards across the state. Can't rule out another flood though if convection fires near the center again. I put my full forecast and analysis at http://weather.schematical.com/

No one should be bashed for being wrong on this one. NHC was wrong too, someone posted earlier that Debby wasn't really hard to predict; I about fell out of my seat lol. Debby could have done so many different things, this is just how it all played out. Should give credit where it's due here, but to bash anyone would seem inappropriate since the system was unpredictable by nature. Levi is a polarizing forecaster here, lots hang on his every word, and lots like to let him know if his every word doesn't come to fruition.
