Fierce storm hammers Southeast U.S.

The Southeast U.S. is under the gun today from a combination of severe thunderstorms, high winds, heavy rain, and coastal storm surge flooding. A tornado was reported on the ground near Eglin Air Force Base, Florida this morning, and tornado warnings have been posted for two separate squall lines moving through the Florida Panhandle and neighboring regions of Alabama and Georgia. These squall lines are expected to intensify and generate tornadoes, heavy rain, and strong winds as they push eastwards today. The Storm Prediction Center (SPC) has put most of Florida, Georgia, South Carolina, and North Carolina in their "Slight Risk" category for severe weather today, warning of the possibility of supercell thunderstorms capable of spawning tornadoes. If the air mass in front of these squall lines becomes sufficiently unstable this afternoon due to solar heating of the lower atmosphere and other factors, SPC may need to upgrade their severe weather category to "Moderate Risk", the second highest level of risk.

The storm's powerful winds blowing over the Gulf of Mexico have created storm surges of 2 - 3 feet along the coast, from New Orleans to the Florida Panhandle. A storm surge of two feet was recorded in Waveland, Mississippi last night and this morning, which caused flooding of low-lying roads in Hancock County. New Orleans recorded 2.42" of rain yesterday from the storm, breaking their record for the rainiest December 1. Radar-estimated rainfall (Figure 2) shows up to five inches of rain has fallen over some regions of the Florida Panhandle, and additional rainfall amounts of 2 - 5 inches are expected along the track of the storm as it heads north-northeast today. Flash flooding was reported in Charleston, SC this morning, closing several roads.

Also receiving a pounding from the storm were the Gulf Coast beaches from Dauphin Island, Alabama, to the Florida Panhandle near Pensacola. A storm surge of two feet, topped by battering waves 10 - 12 feet high, probably caused millions of dollars of erosion damage last night and this morning. A 16-mile stretch of man-made beach encompassing the Alabama coastal communities of Gulf Shores and Orange Beach suffered $5 million in erosion damage from the pounding delivered by Tropical Storm Ida last month. The two beach communities, along with Gulf State Park, spent about $24.2 million in 2005 to strengthen 16 miles of shoreline by dredging about 6 million cubic yards of sand from the sea floor and dumping it on shore. Hurricanes Gustav and Ike in 2008 did about $9.5 million in erosion damage to the Gulf Shores beach. Because the beach is man-made, the Federal Emergency Management Agency and the Alabama Emergency Management Agency treated it as they do bridges and highways, paying 85 percent of the tab to repair storm damage.

Why:
Un-served, underserved and forgotten people are depending on us.

How:
We need one hundred people across the country to commit to walking one mile on this day, and to raise at least $300.00 in sponsorship from friends, family, co-workers, neighbors, etc. Participants can choose where to walk--it can be the park, the mall the neighborhood--anywhere you choose. The first 100 participants to raise at least $300 will receive a commemorative T-Shirt.

To register, simply e-mail your intention to participate at paul@portlight.org

Check the Portlight featured Weather Underground Blog regularly for updates!

Next post
The embattled director of the Climate Research Unit (CRU) of the UK's University of East Anglia announced that he will be temporarily standing aside as director until an independent review resulting from allegations following the publication of emails illegally hacked from his computers. I'll be posting a response tonight or Thursday morning, assuming that today's storm does not generate a deadly tornado outbreak. I'm also working on a post titled, "Don't Shoot the Messenger", in response to charges by the Wall Street Journal in an editorial yesterday that climate scientists have a vested interest in promoting alarmist views of the climate in order to get research funding.

Any good radar pics. of the storm heading toward Central Florida.

We are under a flood watch through Sat. for 4 to 6 inches of rain the next 2 days.

Any other thoughts on this system.

Well, when you watch your team play Sunday you might see some around the Stadium!

Odds aren't bad they'll be playing on some snow on Sunday:
FED EX Field area, Saturday night
Overnight Low
27°F

I broke down and asked my 5-year-old about the possibility of snow. He said maybe...

I read that to mean he thinks it might happen, but doesn't expect anything to accumulate.

I trust his snow forecasts after he totally called for last year's snow more than 2 weeks in advance...and he was adamant and definitive about that one. Used words like "It will" vs. maybe or could.

Looks like Houston 1/4-1"...Baton Rouge may end up with 2-3".

NWS is calling for isolated areas of 2-3". Based on the discussion, they are going more strongly with the GFS, which is forecasting the most snow. The ECMWF is the least aggressive with the snow (calling for a trace), and the NAM is in the middle (isolated totals of an inch).

Snow is heading your way in a few days. 65 to snow only in New England! Although there might might be more snow in the south then up north go figure. Someone in the south is going to get dumped on!!! Maybe up to 8" in localized areas.


Yeh,not sure how much we will get,plus ocean is still pretty warm,so without any artic air around,could end up with a mixture,and depending on the track.

Good Morning Ike, Question for you. Do you think these fronts that come thru cen s fl loose there punch because we have been in a drought since the middle of 2005. In other words not alot of ground moisture. What do you think

No. The reason why the system lost its punch is because the energy (low) was lifting northward while the front (squall line) was dropping southeast. The system simply lost its energy.

Let's see what happens over the next 2 days. A new low is expected to form and travel with its energy across the state giving widespread 2-5 inch rains with a possibility of stronger storms on Saturday.


Interesting observation. I noticed it too. The winds yesterday afternoon were vicious but then around sundown they died down. Think that may have been when the separation occurred?

Good call. I figured as much too because it always seems like we miss out on serious rain no matter how likely it seems that we'll get it. I sleep like a rock but my wife sleeps relatively lightly and neither of us were awoken by any storm activity. .31" is better than nothing though! Keep your fingers crossed!

Good morning everyone.

The total rainfall amount here on my gauge registered just over 1 inch here in North Jax. All of the severe weather reports yesterday and last night were mainly just north of here in Georgia, SC and NC.

I took a look at the ECMWF this morning. This model not as aggressive as the GFS in regards to the GOM system/ upper shortwave for Friday -Saturday period. ECMWF not nearly as moist as the GFS. GFS rather aggressive with showing abundant moisture. Possible 2 inch snowfall amounts in some pockets GFS is forecasting with a swath at or just north of a line along Interstate 10
from interior SE TX , through Louisiana, and up into Jackson, MS. Looks more like wintry mix possible right along the immediate coast.
Most of the WFOs in these areas are apparently going to remain biased toward the GFS for this upcoming event. Should it verifies. Yeah, could be for the second year in arow in early December a very significant Deep Dixie snowfall. Amazing indeed.

I am awaiting the later runs today to see how this may pan out for the Piedmont region of the Carolinas. I will be traveling to Charlotte tomorrow and be there over the weekend. I will be curious to see if the emerging Low Pressure that will begin moving off the SE Atlantic coast on Saturday. There may be some moisture lifting north in the Piedmont as the Low passes that area off the coast. This system may advect enough cold air advection up in that area for brief period of wintry weather there on Saturday.

Have a great day everyone.

We did get some heavy rain last night in Orlando, which was great! It looks as if a much larger rain event is on the way. Computer models are printing 4 to as much as 6" of rain all across Central Florida Fri. & Sat. Flash flooding of low lying areas seems to be a concern. I wouldn't be surprised if we see some strong to severe thunderstorms as well. Central Florida appears to be the bulls-eye on this one.


Looking at the GFS, I think your right. So close here in PBC but not close enough to see anything appreciable.

Quoting TheCaneWhisperer:


Morning.

That's exactly it. As the upper low travels further and further to the NNE, the surface reflection becomes nothing but a decaying frontal boundary. If you notice the 1993 outbreak the parent low traveled ENE out of the GOM over North FLA.

This current storm traveled much further inland and to the N and W than originally modeled, hence the lack of rain/storms in the lower peninsula. I doubt we'll get anything from this today. On the other hand, the disturbance forecast to develop in the GOM today may pack more of a punch to the lower peninsula than the current one as it is forecast to travel ENE.



Looks that way.
