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.

Hey, Tampa people--My daughter wants to go to a concert over there Thursday night. We'll be driving over from Orlando. Do you think there will be any issues getting to the Forum?

TIA

Grew up in the Carolina's. When it's that hot, with humidity, you just look out the window and can see that it's unbearable. I remember as a boy, looking out the window and actually seeing the humidity as it danced in the air many days. Wow that's unbearable, a full week of ninety plus for us here in Wisconsin even. Getting serious here for drought. Farmers are very anxious, this could be a horrible year for yields here. Very close to moving up to the next color up on the drought map, with no help in sight. But I'm thankful we're not in Texas's boat.

Okay, in the last hour the forecast for Raleigh NC went crazy:

From a high of 93 on Thursday to 3 straight days of 109 !!!

Then next Tuesday back to a 'refreshing' 99.

WTH... I know we are due for higher temps later this week, but those numbers look like typos...
I don't see 109, but various sites--NWS, Intellicast, etc.--show three straight days in the triple digits beginning with Friday. I'll actually be in Raleigh on Sunday. Fun...

Massive High Pressure Ridging setting up, the dry air is already beginning to filter in over parts of FL.

Blob of energy just NE of center is getting stronger by the hour. This time the blob is as close to the center as it's been, so this should bode well for it in the coming hours. May actually transition itself to looking like a classical TS in the next two/three days. Question is, will the new blob move east of Debby like the old blob did, or will this new blob interact with the center of circulation and energize the swirl with some real precipitation.

Nice to see some blue skies in Tallahassee today! Bye Debby, and good riddance! Now stop hurting the rest of the state of Florida and head on out to sea...away from land, permanently!

I'll trade you 102 in Hammond for your 98.


LOL. I'll trade you for our 103 in Montgomery. The 850 mb thickness charts looks like we're in for highs of 108 to 114 between now and Sunday. The only thing Debby did for Alabama was give us a breeze, but the subsidence and hot high pressure makes it still extremely oppresive.

Speaking of Debby, why is she still a TS? I know the hurricane hunters found flight level winds at the exact low point of a TS and no bouys in the Gulf are showing over 30 mph. This is all typical of an open low now, and Debby certainly has no characteristics of a tropical storm. I know Florida has had a lot of rain but that happens occasionally just from training thunderstorms caused by your run of the mill low pressure trough. I don't know if the NHC is trying to keep her alive until she gets out to the Atlantic, increase their ACE score, or what, but Debby is the poorest excuse I've ever seen for a TS in my 50 years of weather observations.

Cue Neopolitan to tell me why I'm an idiot. :)

You know it's hot when your hot tub temp is lower than the heat index (108F) and the actual temp (100F) in Jasper County, TX.

If I want to monitor the long range models for july 6-11, what are the best links to use?

Which models go out that far?

About time! Now hopefully the flooding won't be quite as bad as the folks had up in the Panhandle.

Strongest gust so far in eastern Jacksonville has been 52 mph, that was early yesterday. My folks live in New Smyrna Beach, the strongest gust they had was 46 mph.

Don't remember the name of the storm. But last year a tropical storm made landfall in Texas and basically evapoated at landfall. Maybe someone from Texas can chime in.


Definitely Don. Never seen anything like that before. Looked like a decent storm until the bands starting hitting the shore. Then POOF. I don't think the eye/center even made it to shore.

I never saw dry air totally run over a TS like this before. You don't see this too often. There is a lot of dry air between Africa & the Lessor Antiles so that wave in the Mid Atlantic might get choked out. Cape Verde sytems getting choked out by dry air is common early in hurricane season.

REPOST from last blog (for those following the heat and wildfires in Colorado):

Firefighters battling 6-acre wildfire near Bison Drive west of Boulder

Well crud... I know most eyes are on Debby right now, but it sounds like at least one of those brand new fires in Boulder County has gotten enough momentum to warrant an air tanker and helicopter response. Just did a quickie check and this 6-acre-and-growing fire is a mere SIX miles east of my house.

Just have to focus on work a couple more hours and then I can rush home to review my evacuation preparations.

Think humid thoughts for us out here - looks like Ma' Nature has nothing for us in the short-term:

So is Lake City Florida really about to be a city under a lake. Talk about prophetic naming of a city. If anyone is from there please stay safe and listen to all warnings it looks like it could double up there from yesterdays rain totals, that's scary.

This is most certainly the warmest tropical system I've ever been through. Keep going outside expecting it to be cooler out due to rain, overcast and breeze and then wall of warm, wet dog air hits me in the face and I run back into my house and A/C.

Thanks Angela. Maybe,for a future blog you or Dr Masters can add a line about a rather active Tropical Wave now in the Eastern Atlantic. It may not develop but is interesting for being June at that location. It will be very good for some of the Eastern Caribbean islands as it has been dry during this month.

Same for eastern Jamaica...90+ of 400+ water facilities in Jamaica are being affected by drought conditions
